[platform-swt-dev] Printer doesn't stretch any B&W images.

[Arnaud De Muyser <ademuyser@xxxxxxxxxx>]

Hi,

I've seen in Eclipse's search that sometimes,
few printer doesn't print images (transparent one ?).

I'm experimenting a problem with few
images printed by my program, it appear that the one I create from a byte
array (by code),
aren't stretched by printer.
I use same code to draw images on gc
(created from Display or Printer):
          gc.drawImage(
_img, 0,0,oiw,oih, x,ys,iw,ih );
where oiw,oih are size of image, and
iw,ih are size of image rescaled to device (using dpi factors).
This code is used to tile images (I'em
trying to render a filled patterns).

Here is a screen shot (images drawn
to display): 

And here is a scan of the print I got,
as you can see first image is correctly rescaled, but second one not :

(sorry for the bad resolution, but obviously
second images aren't stretched).

the only difference I can see is the
way I create images:
- first comes from a file : 
        new
Image( device, "D:\\tmp\test_image2.png" );
- second comes from a byte array, here
is the piece of code I use:
  private static Image getPattern(
Device device, RGB _fore, RGB _back, byte pattern_[] )
  {
      RGB rgb[] = new
RGB[] { _back, _fore };//_back };
      PaletteData pal
= new PaletteData( rgb );
      ImageData data
= "" ImageData(64,64,1,pal,1, pattern_ );
      data.transparentPixel
= 0;
      Image img_pat_
= new Image( device, data );
      return img_pat_;
  }

Perhaps the way I create image is wrong
?
I'm not sure this printing problem is
due to  SWT or if the postscript interpreter can't handle correctly
this kind of images...
[this will be very strange for a recent
laser printer of a well known company .. ;-)]

Is there any one facing this kind of
behaviour ?
Thanks a lot.

Arnaud.
