The color of the font is wrong. :/

I need to show it in black color, but it is showing black and white. See this sample:

http://imagebin.org/244801

Even I changing my demo to:

Code: [Select]

  chart.LeftAxis.Marks.LabelFont.Size := 12;
  chart.LeftAxis.Marks.LabelFont.Color := $000000;   
  ...
  img.CanvasBGRA.Font.Color := $000000;

> Are you talking about the fact that the letters appear in white ? I suppose it's a PNG issue. Try with another file format.

In JPEG format it's OK. But it loses the quality and duplicate the size. :( See two pictures in attached.

JPG - low quality - 11KB
PNG - high quality - 4KB

I solved the problem.

In the file TAChartAxis, change this code:

Code: [Select]
(Line: 1015)
begin
  FillChar(Result, SizeOf(Result), 0);
  ai := 0;
  for i := 0 to High(FGroups) do begin
to it:

Code: [Select]
(Line: 1015)
begin
  FillChar(Result, SizeOf(Result), 0);
  for i := 0 to High(FGroups) do begin
    ai := 0;

Ok, so it's a PNG issue.

Maybe try with clBlackOpaque (from BGRABitmapTypes) instead of clBlack.

Worked like a charm with clBlackOpaque! 8) Thank very much again buddy.

Now we have only the problem on Linux. I'm trying to solve it, but it is very hard to debug.

My environment:

Lazarus 1.1 r39621 FPC 2.7.1 x86_64-linux-gtk 2 (Linux Mint 14, GTK, 64bit)

I've not tested it on Linux, but it should work in theory.
