Sniff. :'(
I'm trying to generate charts in my CGI apps:
http://silvioprog.com.br/cgi-bin/cgi1
And PDF with PowerPDF (I'll send a patch soon to remove some LCL
dependences):
http://silvioprog.com.br/cgi-bin/cgi2 (Clique aqui = Click here)
For texts, it should be able to add it.
Yes:
procedure TFPCanvasDrawer.EnsureFont;
begin
{$IFDEF USE_FTFONT}
if FFont nil then exit;
FFont := TFreeTypeFont.Create;
FFont.Resolution := 72;
FFont.AntiAliased := False; I'll set it for True. It would be
interesting if there was a property to handle it.:)
FCanvas.Font := FFont;
{$ENDIF}
end;
Thanks for the fast reply man! :)
ps. I'm very, very happy with the Free Pascal. Now, I'm creating fine my
PDFs and charts. I will make one layer to facilitate the use of some
classes of PowerPDF and TAChart.

Silvio, TAchart has a BGRABitmap backend mode, it creates great anti-aliased
graphics (both lines and text). I didn't tested on CGI without linking against
graphic libraries, I think it relies on TCanvas, so maybe it won't work, but it
worth a try.

Also you could generate your charts in the browser, using a JavaScript/Html5 library like this one: http://www.humblesoftware.com/flotr2/ Leonardo M.

It works fine (see result here: http://imagebin.org/244612) in Win32 with
this code:
program noguidemo;
{$mode objfpc}{$H+}
uses

FPCanvas,
FPImage,
FPImgCanv,
TATools,
TAGraph,
TASeries,
TADrawerCanvas,
TADrawUtils,
BGRABitmap,

TADrawerBGRA;
var
chart: TChart;
bs: TBarSeries;
img: TBGRABitmap;
d: IChartDrawer;
begin
chart := TChart.Create(nil);
chart.LeftAxis.Marks.LabelFont.Name := 'Arial';
chart.LeftAxis.Marks.LabelFont.Size := 10;
chart.LeftAxis.Marks.LabelFont.Orientation := 450;

chart.BottomAxis.Grid.FPColor := colDkGray;
chart.Color := $FFA0A0;
chart.BackColor := $FF;
bs := TBarSeries.Create(nil);
chart.AddSeries(bs);
bs.AddXY(1, 10);
bs.AddXY(2, 7);
bs.AddXY(3, 8);
img := TBGRABitmap.Create(chart.Width, chart.Height);
d := TBGRABitmapDrawer.Create(img);
img.CanvasBGRA.Font.Antialiasing := true;
img.CanvasBGRA.Font.Name := 'Arial';
d.DoGetFontOrientation := @CanvasGetFontOrientationFunc;
chart.Draw(d, Rect(0, 0, chart.Width, chart.Height));
img.SaveToFile('test.png');
img.Free;
bs.Free;
chart.Free;
end.
But, with NoGUI, the error is:
