+
+Please send bug reports and feature requests to http://bugs.kde.org/.
+Don't hesitate to report bugs nor hesitate to send us your wishes - it
+provides valuable feedback that will help to improve future versions of
+KolourPaint and you will not receive flames for reporting duplicates.
+
+
+This file lists known bugs in this version that are not considered
+"release critical" and are difficult to fix:
+
+
+1. Flicker when zooming in/out.
+
+3. Tool Box & Colour Box RMB ToolBar Menus do not work.
+
+4. Image dialog spinboxes should accept Enter Key (instead of the dialog's
+ OK button) after the user has typed something.
+
+ OR
+
+ Spinboxes should signal that their values have changed every time the
+ user changes the text (rather than after pressing Enter or clicking on
+ another spinbox etc.).
+
+ The need for the "Update Preview" button and the difficulty of keeping
+ the percentages and dimensions in sync in the Resize / Scale dialog are
+ manifestations of the current QSpinBox behaviour.
+
+6. a) The undo history and document modified state are not updated during
+ the drawing of multi-segment shapes (Polygon, Connected Lines,
+ Curve). They are however updated after shapes' completion.
+
+ b) The text and brush-like tools set the document modified flag even if
+ user cancels the draw operation.
+
+ c) Select a region, manipulate it (e.g. move), undo - the document is
+ still marked as modified (because 2 commands - the create selection
+ and the move - were added but only one was undone).
+
+7. Certain shapes may have the wrong size (usually only a pixel off and
+ only in extreme cases) e.g. an ellipse of height 1 always has a width 1
+ pixel less than it should be. This is a Qt bug.
+
+8. At zoom levels that aren't multiples of 100%, parts of the image may
+ appear to move when the user interacts with it. Other minor redraw
+ glitches may also occur at such zoom levels.
+
+9. Keyboard shortcut changes do not propagate to other KolourPaint windows
+ (but will propagate to future windows).
+
+10. "File/Open Recent" entries are not updated interprocess.
+
+11. The blinking text cursor will "disappear" if you type more text than
+ you can fit in a text box.
+
+12. You cannot select only parts of the text you write.
+
+13. Due to a workaround for a Qt bug, writing text with the foreground
+ colour set to transparent is incredibly slow. Write your text in
+ another colour and then set the foreground colour to transparent after
+ you've finished typing to avoid this issue.
+
+14. The text cursor may be momentarily misrendered when scrolling the view.
+
+17. a) Using KolourPaint on a remote X display may result in redraw errors
+ and pixel data corruption.
+
+ b) KolourPaint is screen depth dependent. Opening an image with a
+ an alpha channel and/or a depth higher than the screen and then
+ saving it will likely result in loss of colour information. Also,
+ 8-bit screens are not supported at all. To reduce data loss, run
+ your screen at 24-bit. This bug will be addressed in a future
+ version of KolourPaint.
+
+19. Read support for EPS files is extremely slow. You should not enable
+ the "Save Preview" dialog when saving to EPS. This is an issue with
+ KDE.
+
+20. Pasting a large image (esp. one that doesn't compress well as PNG)
+ into an image editor (not necessarily KolourPaint) running as
+ different process from the KolourPaint which was the source of the
+ image, on a sufficiently slow computer, may fail with the following
+ output to STDERR:
+
+ "kolourpaint: ERROR: kpMainWindow::paste() with sel without pixmap
+ QClipboard: timed out while sending data"
+
+ This is a Qt bug.
+
+21. It is not always possible to copy and paste between 2 instances of
+ KolourPaint running different Qt versions. See
+ QDataStream::setVersion().
+
+22. The Emboss, Blur and Sharpen effects give different results depending
+ on _both_:
+
+ a) The KDE version KolourPaint was compiled with
+ (due to KImageEffect not supporting strength settings for these
+ effects in KDE 3.0, KolourPaint repeats these effects in order to
+ simulate strength)
+
+ b) The KDE version KolourPaint is running under
+ (e.g. for the same function calls, KDE 3.2's effects are slower but
+ give better results than those in KDE 3.0)
+
+23. Changing tool options while in the middle of a drawing option may
+ confuse KolourPaint. For instance:
+
+ a) With the brush tools, the cursor incorrectly appears.
+
+ b) With the rectangle-based tools, the temporary pixmap does not resize
+ when the line width increases.
+
+25. Sometimes when you take a screenshot of a window, and then paste in a
+ new window, it will be greyscale. When pasting again, it will still be
+ greyscale. Cannot consistently reproduce. [Thurston]
+
+26. Drawing with the keyboard is unreliable. Depending on the X server,
+ either holding down Enter may continually switch between drawing and
+ not drawing or KolourPaint may fail to detect the release of the Enter
+ key.
+
+27. InputMethod has not been tested at zoom levels other than 100%.
+
+28. KolourPaint has not been tested against invalid or malicious clipboard
+ data.
+
+
+Issue with XFree86 <= 3.3.6 with the "Emulate3Buttons" Option
+=============================================================
+
+When drawing, clicking the left or right mouse button that did not
+initiate the current operation will, in this order:
+
+1. finalise the current drawing operation
+2. attempt to paste the contents of the middle-mouse-button clipboard
+
+instead of canceling the current drawing operation.
+
+This is due to XFree86 sending a release notification for the button that
+initiated the drawing operation, followed by a press notification for the
+emulated 3rd button; instead of just a single press notification for the
+button that is intended to cancel the operation. This works correctly in
+XFree86 4.x with "Emulate3Buttons" on because it is harder to trigger the
+emulation for the 3rd button as it is only invoked if the left and right
+buttons are pressed at almost the same time.
+
+Possible solutions:
+
+a) Use XFree86 4.x or an X server from another vendor (e.g. X.org).
+b) Press Escape in KolourPaint to cancel the current drawing operation
+ instead of using the problematic click method described above.
+c) Disable "Emulate3Buttons".

+KolourPaint 1.4_relight Series (branches/KDE/3.5/)
+===============================
+
+KolourPaint 1.4.9_relight (Frozen ???)
+
+ * Ensure selection operations always repaint correctly
+ [the effects of this change are unlikely to be functionality visible]
+
+KolourPaint 1.4.8_relight (Frozen 2007-10-08)
+
+ * Always enable the paste actions to guarantee that pasting from
+ non-Qt applications is always allowed (non-Qt applications do not
+ notify KolourPaint when they place objects into the clipboard)
+
+ * Paste transparent pixels as white instead of uninitialized colors,
+ when the app does not support pasting transparent pixels (such as
+ OpenOffice.org)
+
+ * Make "Edit / Paste in New Window" always paste white pixels as white
+ (it used to paste them as transparent when the selection transparency
+ mode was set to Transparent)
+
+ * Saving, exporting and printing a document with an active text box,
+ that has opaque text and a transparent background, antialiases the
+ text with the document below
+
+ * "Edit / Paste From File..." respects the "Transparent" selection mode
+
+ * Focus an input field when the "Skew", "Rotate" and "Resize / Scale"
+ dialogs are displayed -- this allows the user to edit values without
+ an extra mouse click
+
+ * Add error dialogs for:
+ - if scanning support is unavailable
+ - running out of graphics memory during a scan
+
+ * Other minor changes -- some of these are:
+ - Finish the current shape in more cases of menu item accesses
+ - [internal] kpDocument::selectionCopyOntoDocument() marks the document
+ as modified
+ - More comments
+
+KolourPaint 1.4.7_relight (Frozen 2007-05-14)
+
+ * Save local files atomically - KolourPaint will no longer truncate
+ an existing file if the KImageIO library for the file format is
+ missing or if you run out of disk space.
+
+ * Add "File / Scan..." feature (Martin Koller)
+
+ * Add global session save/restore (Bug #94651)
+
+ * Make "File / Open Recent" consistently work when multiple windows are
+ open
+
+ * CTRL+C'ing a text box also places the text in the middle-mouse-button
+ clipboard, in lieu of being able to highlight the text to do this
+
+ * Change minimum allowed zoom level for the grid from 600% to 400%
+
+KolourPaint 1.4.6_relight (Frozen 2007-01-13)
+
+ * Fix crash triggered by rapidly deselecting the selection after
+ drag-scaling it (Bug #117866)
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+KolourPaint 1.4.5_relight (Frozen 2006-09-19)
+
+ * Translation updates
+
+KolourPaint 1.4.4_relight (Frozen 2006-07-12)
+
+ * Minor code cleanups and corrections
+
+KolourPaint 1.4.3_relight (Frozen 2006-05-02)
+
+ * Probably translation updates
+
+KolourPaint 1.4.2_relight (Frozen 2006-03-12)
+
+ * Printing improvements (Bug #108976)
+ - Respect image DPI
+ - Fit image to page if image is too big
+ - Centre image on page
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+KolourPaint 1.4.1_relight (Frozen 2006-01-15)
+
+ * Updated documentation (Thurston)
+
+KolourPaint 1.4_relight (Frozen 2005-11-08)
+
+ * New icons (Danny Allen, Nuno Pinheiro)
+
+ * Tool Box icon size is 22x22, not 16x16, at screen resolution >= 1024x768
+
+ * CTRL + Mouse Wheel = Zoom
+
+ * While freehand selection scaling, holding Shift maintains aspect ratio
+
+ * Prevent accidental drags in the Colour Palette from pasting text
+ containing the colour code
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Cells in the bottom row and cells in the rightmost column of the Colour
+ Palette are now the same size as the other cells
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Text drops to the empty part of the scrollview will not be placed
+ outside the document
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Rename icons from "hi" to "cr" - back to the state of 1.0 (Danny Allen)
+ but leave application icons as "hi" (Jonathan Riddell)
+
+ * Enforce text box font height to prevent e.g. Chinese characters in
+ buggy fonts from enlarging the text box and putting the cursor out of
+ sync with the text
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Clicking in a text box selects a character based on its midpoint -
+ not leftmost point - to be consistent with all text editors
+ (esp. noticeable with big fonts)
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Return and Numpad 5 Key now draw
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Tool Actions placed outside the Tool Box resize with their toolbars
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Ensure Color Similarity maximum is 30, not 29 due to gcc4
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Tool Box traps right clicks (for the RMB Menu) on top of tool options
+ widgets and the empty part of the Tool Box
+ [also in branches/KDE/3.[34]/, branches/kolourpaint/1.2_kde3/]
+
+ * Correct and update image format associations to all formats supported
+ by KDE 3.5 (kdelibs/kimgio/:r466654)
+
+ * String fixes (Stefan Winter)
+ [also in branches/KDE/3.4/]
+
+ * Other string fixes (Malcolm Hunter, Clarence Dang, Stephan Binner)
+
+
+KolourPaint 1.4_light Series (branches/KDE/3.4/)
+============================
+
+KolourPaint 1.4_light (Frozen 2005-02-22)
+ * Antialias text when the text box has a transparent background (Bug #24)
+ [later backported to branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Add Unzoomed Thumbnail Mode and Thumbnail Rectangle
+ * Add RMB context menu for when a selection tool is active (closing KDE
+ Bug #92882)
+ * More intuitive "Set as Image" behaviour (esp. with selection borders).
+ Thanks to Michael Lake for the feedback.
+ [later backported to branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * InputMethod support
+ [later backported to branches/kolourpaint/1.2_kde3/]
+ * Save "More Effects" dialog's last effect to config file
+ * Save "Resize / Scale" dialog's last "Keep aspect ratio" setting to
+ config file
+ * Add "Help / Acquiring Screenshots"
+ * Fix selection regressions introduced in 1.2:
+ - Make selection dragging with CTRL work again (copies selection onto
+ document)
+ - When creating freeform selections, include the starting point; also
+ avoids a QRegion crash with constructing 1-point regions
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Fix other selection bugs:
+ - When the user drags very quickly on a resize handle, resize the
+ selection instead of moving it
+ - Draw resize handles above the grid lines - not below - so that the
+ handles are always visible if they are supposed to be there
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Smaller selection and text box resize handles (visually not
+ actually) - covers up fewer selected pixels, doesn't cover up text
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Restore mouse cursor after deselecting selection/text tools
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Empty text clipboard fixes:
+ - Don't get stuck on a wait cursor after attempting to paste empty
+ text into a text box
+ - Prevent pasting text from creating a new text box if text is empty
+ - Prevent copying of empty text box
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Speed up renderer (most noticeable with diagonal drag-scrolling at
+ high zoom)
+ - Don't paint anything outside of the view's visible region
+ (previously, clipped only on view _widget_ region)
+ - Region-aware: paint component rectangles of the update region,
+ rather than the bounding rectangle
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * When changing between colour depth and quality widgets in the save
+ filedialog, make sure "Convert to:" and "Quality:" are correctly
+ rendered (hacking around a Qt redraw glitch)
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Fix crash after using the Colour Picker if it was the first used tool
+ [kolourpaint-1.2.2_kde3-color_picker_crash.diff]
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Fix crash due to text box when scaling image behind it
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Even when the thumbnail has focus (and not the main window), blink the
+ text cursor in all views
+ [kolourpaint-1.2.2_kde3-thumbnail_blink_text_cursor.diff]
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Correct "Soften" and "Sharpen" commands' command history names
+ * Correct invert commands' command history names
+ * Fix remaining untranslatable strings (closing KDE Bug #85785)
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Update image format associations to all formats supported by KDE 3.4
+ * Remove unused images in doc directory
+ [also in branches/KDE/3.3/, branches/kolourpaint/1.2_kde3/]
+ * Correct kolourpaint.desktop "Terminal=" and "Categories=" syntax
+ (Benjamin Meyer)
+
+
+KolourPaint 1.2 Series (branches/KDE/3.3/)
+======================
+
+Version 1.2 "ByFiat Everytime" (2004-08-18)
+ * Add up to 500 levels of Undo/Redo (minimum of 10 levels, maximum of
+ 500 as long as the total history size < 16MB)
+ * Add freehand resizing of image
+ * Add freehand smooth scaling of selections
+ * [also in 1.0 branch] New icons (Kristof Borrey)
+ * [also in 1.0 branch] Prefer Crystal SVG text icons over KolourPaint's
+ * [also in 1.0 branch] Add documentation in the KDE Help Centre
+ * Add drag scrolling
+ * Add "More Effects" dialog:
+ - Balance (Brightness, Contrast, Gamma)
+ - Emboss
+ - Flatten
+ - Invert (with choice of channels)
+ - Reduce Colours
+ - Soften & Sharpen
+ * File saving improvements:
+ - Support colour depths (optional dithering) and "colour monochrome"
+ - Support JPEG quality
+ - Realtime file dialog preview with estimated file size
+ - Retain PNG metadata
+ - Prompt when attempting lossy save
+ - Correctly save transparent selections (not as opaque)
+ * Dither more often when loading (and pasting) images for better quality
+ * Single key shortcuts for all tools and tool options (automatically
+ turned off when editing text but can then use Alt+Shift+<key>)
+ * Arrow keys now move one document pixel - not view pixel - at a time
+ (more usable when zoomed in)
+ * Fix selection bugs:
+ - Fix duplicate "Selection: Create" undo entries (Bug #5a)
+ - Allow redoing of selection operation if border deselected (Bug #5b)
+ - Don't print to STDERR when undoing a selection border create
+ operation and border has already been deselected
+ - [also in 1.0 branch] When pulling a selection from the document,
+ only set the bits of the document to the background colour where the
+ transparent selection is opaque in the same place (this is only
+ noticeable with colour similarity turned on). Now moving a
+ selection away and then back to its original place is always a NOP
+ as it should be.
+ * Selections can be deselected using Esc or clicking on icon in Tool Box
+ * Accidental drag detection when deselecting selections or text boxes
+ * Prevent selection from being moved completely offscreen (at least 1
+ pixel of the selection will stay within the view)
+ * Speed up copying selection when transparency is on
+ * Improve Text Tool usability:
+ - Allow single click creation of text box with a sane default size
+ - Allow freehand resizing of text boxes
+ - Add Opaque/Transparent selector for greater usability and
+ consistency with selections
+ - Minimum size is now 7x7 document pixels (1x1 - not 4x4 - border)
+ - Text cursor doesn't overlap border anymore
+ - When dropping text, paste at drop point
+ - When MMB pasting creates a new text box, do so at mouse position
+ * When MMB pasting text in an existing box, correctly paste multiline
+ clipboard contents
+ * Improve text quality:
+ - With a transparent background, don't antialias foreground opaque
+ text with arbitrarily chosen black
+ - Make sure transparent text shows up on opaque (usually, grey was
+ problematic) background
+ * Improve Resize/Scale dialog usability:
+ - Add Smooth Scale (useful for creating screenshot thumbnails)
+ - Allow manipulating image when selection is active
+ - Operation choices stand out as massive, easily clickable buttons
+ - Default focus on operation choices
+ * Warn if Resize/Scale, Rotate or Skew will take lots of memory
+ * Limit startup image size to 2048x2048
+ * Eliminate flicker when scrolling
+ * Thumbnail fixes:
+ - Reduce flicker when appearing (Bug #2)
+ - More reasonable minimum size (actually enforce it)
+ - [also in 1.0 branch] Use deleteLater()
+ - [also in 1.0 branch] Save geometry even if it's closed very quickly
+ after a geometry change
+ * Restore last used tool and tool options on startup
+ * Add Export, Copy To File, Paste From File, Paste in New Window,
+ Full Screen Mode
+ * Add Zoom In/Out buttons to main toolbar
+ * Rename Crop options in an attempt to reduce confusion:
+ - "Autocrop" --> "Remove Internal Border" when selection active
+ - "Crop Outside Selection" --> "Set as Image (Crop)"
+ * "Set as Image" changes:
+ - Enable for text boxes
+ - Underneath transparent bits of selection, fill image with
+ transparent rather than with background colour
+ * Permit "reloading" of an empty document
+ * Fixes when the current URL doesn't exist:
+ - Don't reload if underlying file disappeared
+ - Don't add non-existent file to Recent Files history
+ - Ask to save before mailing or setting as wallpaper
+ * Only enable Show Path when there is a URL
+ * Pop up dialog (instead of printing to STDERR) and disable Edit/Paste
+ on CTRL+V if the clipboard contents disappeared due to the source
+ application quitting (and Klipper didn't retain clipboard contents)
+ * Image/Clear now always sets _everything_ within the selection boundary
+ to the background colour - including transparent pixels
+ * Add Preview button to Colour Similarity Dialog to work around Bug #4
+ regarding spinboxes and enter key
+ * Colour Picker disallows trying to pick colour outside of image
+ * Make sure colour palette contains valid and visible colours at 8-bit
+ * [also in 1.0 branch] Fix (big) memory leak on kpSelection destruction
+ (Albert Astals Cid)
+ * Don't leak image dialogs' memory
+ * [also in 1.0 branch] Don't let C++ destruct the mask bitmap before its
+ painter when dbl-clicking the color eraser does NOP (avoids
+ QPaintDevice and X error)
+ * [also in 1.0 branch] Check for QImageDrag::canDecode() before calling
+ QImageDrag::decode() (prevents X and valgrind errors)
+ * [also in 1.0 branch] Fix compilation problem with QT_NO_ASCII_CAST
+ (Waldo Bastian)
+ * [also in 1.0 branch] Decrease application preference to below that of
+ a viewer (Stephan Kulow)
+ * Remember dialog dimensions
+ * Remove double dialog margins
+ * Fix missing i18n()'s
+ * Fix some untranslatable strings
+ * [also in 1.0 branch] Corrected several strings
+ * Remove unused icons
+

+KolourPaint Version 1.4.9_relight (KDE 3.5.9 Release Frozen ???)
+http://www.kolourpaint.org/
+

+
+
+1. What is KolourPaint?
+=======================
+
+KolourPaint is a free, easy-to-use paint program for KDE.
+
+It aims to be conceptually simple to understand; providing a level of
+functionality targeted towards the average user. It's designed for daily
+tasks like:
+
+* Painting - drawing diagrams and "finger painting"
+* Image Manipulation - editing screenshots and photos; applying effects
+* Icon Editing - drawing clipart and logos with transparency
+
+It's not an unusable and monolithic program where simple tasks like drawing
+lines become near impossible. Nor is it so simple that it lacks essential
+features like Undo/Redo.
+
+KolourPaint is opensource software written in C++ using the Qt and KDE
+libraries.
+
+
+2. Features
+===========
+
+* Undo/Redo Support (10-500 levels of history depending on memory usage)
+
+* Tools (single key shortcuts available for all tools)

+
+* Selections (fully undo- and redo-able)
+ - Rectangular, Elliptical, Free-Form shapes

+ - Freehand resizeable
+
+* Colour Similarity means that you can fill regions in dithered images and
+ photos
+
+* Transparency
+ - Draw transparent icons and logos on a checkerboard background
+ - All tools can draw in the "Transparent Colour"
+
+* Image Effects
+ - Autocrop / Remove Internal Border
+ - Balance (Brightness, Contrast, Gamma)
+ - Clear, Emboss, Flatten, Flip, Invert (with choice of channels)
+ - Reduce Colours, Reduce to Greyscale, Resize, Rotate

+Eliminates flicker when moving document resize lines / dragging resize
+handles by:
+
+1. Not erasing areas that will be subsequently painted over with resize
+ lines.
+2. Erasing the old areas and painting the new ones atomicly by using
+ clever NOT'ing of pixels.
+
+Additionally, recover the resize lines after a window pops up momentarily
+over KolourPaint (kpViewScrollableContainer::windowActivationChange()).
+
+Critical bugs with this code and scrollbars:
+
+1. Drag scrolling leaves trails of resize lines.
+2. Moving the mouse cursor above the start of the document does not result
+ in a resize line at document y = 1.
+
+Because I'm still debugging, there are a few hacks in the code such as
+"m_resizeLinesDontPaintClever".

+// all other candidate pixels in that side are tested against
+// for similarity. But if the reference color happens to be at
+// one extreme of the range of colors in that side, then pixels
+// at the other extreme would not be deemed similar enough. The
+// key is to find the median color as the reference but how do
+// you do this if you don't know which pixels to sample in the first
+// place (that's what you're trying to find)? Chicken and egg situation.
+//
+// The other heuristic that is in doubt is the use of the average
+// color in determining the similarity of sides (it is possible
+// to get vastly differently colors in both sides yet they will be
+// considered similar).
