This file has a list of functionality not yet implemented or issues that have to be fixed in libgdiplus. ---- Functionality not implemented * Image formats - WMF and EMF. We have limited support metafiles. ---- Not implemented / partially implemented functions * Handle functions Functions that use or create Win32 handles and are not yet implemented (except for window and device needed in System.Windows.Forms.) GdipCreateBitmapFromResource GdipCreateFontFromDC GdipCreateFromHWND * Generic functions GdipBeginContainer2 GdipBeginContainerI GdipGetPixelOffsetMode [2] GdipGetTextContrast [2] GdipSetPixelOffsetMode [2] GdipSetTextContrast [2] GdipTransformPoints GdipTransformPointsI * Image handeling GdipSetImageAttributesThreshold GdipSetImageAttributesOutputChannelColorProfile GdipGetImageAttributesAdjustedPalette GdipSetImageAttributesOutputChannel GdipLoadImageFromStream GdipSaveImageToStream GdipSaveAdd GdipSaveAddImage * Pens and brushes GdipSetPenDashCap197819 [2] GdipGetPenDashCap197819 [2] GdipSetPenCustomStartCap [3] GdipGetPenCustomStartCap [3] GdipSetPenCustomEndCap [3] GdipGetPenCustomEndCap [3] * Functions related to paths GdipAddString [1] GdipAddStringI [1] GdipIsOutlineVisiblePathPoint [4] GdipIsOutlineVisiblePathPointI [4] GdipIsVisiblePathPoint [4] GdipIsVisiblePathPointI [4] GdipWindingModeOutline GdipWidenPath GdipWarpPath Notes [1] Partially implemented. LayoutRect and StringFormat are ignored. [2] Function exists (return Ok) but doesn't do anything (visually or not) [3] Function exists (return Ok) but only display a warning on the console [4] Partially implemented. GpGraphics is ignored. ---- Known Limitations * Maximum of 32bpp GDI+ supports bitmaps with more than 32bpp. http://bugzilla.ximian.com/show_bug.cgi?id=80693 * Coordinates limitations GDI+ supports 32bips of precision (Cairo is limited to 15bits) http://bugzilla.ximian.com/show_bug.cgi?id=79729 * Cairo doesn't support 8-bit pseudocolor visuals http://bugzilla.ximian.com/show_bug.cgi?id=77937 * Cairo doesn't implement cairo_stroke_to_path GdipWidenPath implementation depends on this feature. http://bugzilla.ximian.com/show_bug.cgi?id=78110 ---- last updated: August 9th, 2007
