PDF to other PGraphics object
May 14th, 2006, 8:43pm  
Currently I'm having to duplicate my line draw method, once for buffer.line(x1,y1,x2,y2) and then again line(x1,y1,x2,y2) in order for PDF to record it.

Is there a way of telling the PDF renderer to use a preferred PGraphics object, rather than the default. It's not a huge issue, but affects performance.

I came up with this, which seems to handle it:

Code:


  PGraphics3 tmp = (PGraphics3) g;
  this.g = canvas;

  line( x1, y1, x2, y2); 

  this.g = tmp;

why not use PDF as the renderer in size()? or create a PGraphicsPDF and draw to that directly? "performance" isn't really a feature of PDF anyway.

I'm drawing to a buffer which is 4* larger than the main window  and then blitting sections of this to the main window.

To do this, I draw directly to a buffer PGraphics object and then blit this direct to the main window.
Would it be possible to copy(); straight from the PDF to the main window, it's giving me a null pointer for lack of a this.recorder.loadPixels(); given that it extends PGraphics2 (I'm guessing).

The casting seems ok for now. The main problem is the performance difference between P3D and JAVA2D. I can draw fancy strokeWeights to the PDF, but can't see what I've done until its all over.

A good rummage through the processing source will probably clarify things a bit.
