BGRAsvg: Image to big
« on: March 04, 2021, 12:24:00 am »
Hi!

BGRAsvg: Image to big ???

And I thought they are scalable .....

Just a very simple code to load a svg and draw it on a Canvas2D.
The file is a carddeck file from AisleRiot and is loaded without problems in InkScape.

The error message appears at

Code: Pascal  [Select][+][-]
  1. svg.StretchDraw(tmp.Canvas2D, .......
  2.  


Can anybody tell me what's going on???

Thanx
Winni

Can you look at the stack trace?

That might be related to text rendering. Maybe using vectorized text renderer would solve this.

Hi!

I will look later in the night. Just busy.

The source is simple:

Code: Pascal  [Select][+][-]
  1. procedure TForm1.Button8Click(Sender: TObject);
  2. const svgfile= './bonded.svg';
  3. var svg: TBGRASVG;
  4.     tmp: TBGRAbitmap;
  5. begin
  6. svg := TBGRAsvg.create(svgfile);
  7. tmp := TBGRAbitmap.create (Image1.width,image1.height,cssWhite);
  8. svg.StretchDraw(tmp.Canvas2D,0,0,image1.width,image1.height,false); // <=== Crash
  9. svg.free;
  10. tmp.draw(Image1.Canvas,0,0,true);
  11. tmp.free;
  12. end;
  13.  

The bonded cardset svg in the attachment

Thanx
Winni

Grrrr! This software does not allow svg files to be attached!
Allways 20 years behind the state of art!

Have you enabled debugging in BGRABitmap?

I cannot reproduce the error. Though I suggest to add:
Code: Pascal  [Select][+][-]
  1.     tmp.FontRenderer := TBGRAVectorizedFontRenderer.Create;  

Note that this SVG contains elements that are not rendered yet by BGRASVG.

Hi and thanx!

Assigning the fontrenderer did the trick: No crash anymore.

But as you said: Not all elements are rendered until now.
Instead of a carddeck only two rectangles are shown.

Bur anyway: One step forward.

You're welcome.

Improving SVG support is on my todo list, when I have enough spare time.
