New version of BGRABitmap

[fcu]

unfortunately i still get the same error when trying to install bglcontrols.lpk

[circular]

Ok I found the problem. It was a circular reference of units.

That's fixed in version 10.8.1:

Hi

Is it possible to animate SVG using BGRABitmap, could not find any info here or on the interweebs?

Like https://css-tricks.com/guide-svg-animations-smil/

Thanks for an awesome library btw.

Hi,

Glad you like the library.

For now BGRABitmap does not handle SVG animation.

Regards

New version of BGRABitmap (10.9)
https://github.com/bgrabitmap/bgrabitmap/releases

Compatibility:
- BGRABitmap can now be used be MSEgui
- improve Delphi portability by avoiding += and using more consistent integer types
- add UTF8toUTF16 and UTF16toUTF8 to BGRAUTF8 unit
- add DeleteFileUTF8 to BGRAUTF8 unit for non-LCL context

Vectors:
- vectorized font: add kerning (putting closer letters that fits like AV)
- vectorized font: add OutlineJoin property
- FreeType: fix TextFitInfo for unicode chars
- text layout: add UsedWidth to TBidiTextLayout
- text layout: add TextSizeMultiline to TBGRABitmap
- avoid crash when layer editor matrix is not inversible

Refactoring:
- added BGRAClasses unit with used classes (instead of Classes and Types)
- using Avl_Tree FPC unit instead of Lazarus AvgLvlTree
- TColor byte order depends on global directive TCOLOR_BLUE_IN_LOW_BYTE

BGRABitmap v11

https://github.com/bgrabitmap/bgrabitmap/releases

- functions that used to return TBGRACustomBitmap now return the type of the current class. So no need to write for example "Resample(...) as TBGRABitmap".

- optimize TFillShapeInfo.IsPointInside by not allocating the intersection array each time.

- basic support for Unicode in BGRAFreeType. This includes Arabic and alpha-syllabic scripts, though there are some limitations. For example, multiple marks in Hindi placement is not adjusted and specific glyph substitutions are not handled. This would require to read the GSUB and GPOS table of the font.

- added DrawPixelF, ErasePixelF, AlphaPixelF

- added fqFineClearType global function, to get the RGB/BGR order used by the system

- fix PNG reader for 24-bit RGB with transparent entry

Hi, can't compile in FPC / Lazarus trunk

bgrafreetype.pas(900,18) Error: Identifier idents no member "CharKerning"

Code: Pascal  [Select][+][-]

1. function TFreeTypeTypeWriter.ComputeKerning(AIdLeft, AIdRight: string): single;
2. {$IFDEF LAZFREETYPE_PROVIDE_KERNING}
3. var
4.   uLeft, uRight: LongWord;
5. begin
6.   if (AIdLeft = '') or (AIdRight = '') then exit(0);
7.   uLeft := UTF8CodepointToUnicode(@AIdLeft[1], UTF8CharacterLength(@AIdLeft[1]));

If you look in the definition of TFreeTypeFont in EasyLazFreeType, can you actually find the CharKerning property?

If you can, then maybe you need to rebuild the IDE for it to know about it. Otherwise, if it is not there, then the file may not be updated.

[lainz]

I have EasyLazFreeType from lazarus\components\lazutils\easylazfreetype.pas

And in that file nowhere is included CharKerning.

So maybe is another problem with trunk, the property was removed or replaced with something else..

Edit 2: I've commented that lines and the BGRABitmap library compiles fine, any side effects?

Edit: Another problem is that the new version does not compile with MSEide.

bgrafreetype.pas(31,57) Fatal: Can't find unit EasyLazFreeType used by BGRAFreeType
Fatal: Compilation aborted

This time I did not copy the bgrabitmap folder into lib\common but added a reference with a global macro to the path, and added in project options the macros. I must define something else?

Please create a global macro LAZUTILSDIR that point to /the/directoryof/lazarus/components/lazutils/

And use that macro in Project - Options - Make - Directories

The problem was I forget to add the define -dBGRABITMAP_USE_MSEGUI

Hello Lainz.

OK, I will try your new commits now.

Write you later on BGRAgui Github.

Thanks, yes nothing new, only I fixed the readme and the compilation, moving only the paint procedure from protected to public, nothing more. But that makes it to compile.
