Hello.
I am using the draw2d PrinterGraphics class to print a diagram figure.
However, when scaling, the text of my figures do not scale. (Only the
text is not scaling correctly. ) The text scaling works for the zoom
within the diagram editor.
The PrinterGraphics super class ScaledGraphics has the method
int zoomFontHeight(int height) {
return (int)(zoom * height);
}
but in PrinterGraphics this method is
int zoomFontHeight(int height) {
return height;
}
Anyone else encountering this? Could not find any bugs logged against
this.
Regards,
S.

Hi Martin,
I actually got around this by passing in an instance of ScaledGraphics into
PrinterGraphics, then calling scale on the scaledGraphics.
Graphics g = new SWTGraphics(gc);
scaledGraphics = new ScaledGraphics(g);
printerGraphics = new PrinterGraphics(scaledGraphics, printer);
Regards,
S.

Hi S., Randy,
thank you for the tip. This trick solved the problem.
You find attached a print implementation which prints a grahical view with
the zoom level defined by the zoom manager. Other "zoom" levels can be set
with setZoom() before calling run().
Furthermore it prints "tile" pages when the figure does not fit on a single
page.
So this implementation has really benefits in comparison to the standard
print operations.
Best regards,
Martin

You guys are missing the more important issue. We do not have a way to
reproduce the problems you are describing. Please open a bugzilla with all
relevany information. Printing works fine for me. Perhaps if I use your
workaround, Fonts will be double scaled, making them too large.

PrinterGraphics has been fixed:
int zoomFontHeight(int height) {
int printerDPI = printer.getDPI().y;
int displayDPI = Display.getCurrent().getDPI().y;
double factor = zoom * displayDPI / printerDPI;
return (int)(height * factor + 0.0000001);
}
Your workaround should still work, but is no longer necessary.
