Hello,

I am using paperclips to print pages and show previews. Printing works well,
but when previewing the transformation stored in the GC
(gc.get/setTransform) is not respected. Instead everything is painted
unscaled from the untranslated origin of the GC. This seems to be a bug. Any
help is greatly appreciated.

Hello again,

to be more precise:

A printer image GC is initiliazed with 300 dpi and scaled to fit into
the screen and thus having a scaling factor of about 0.14... . Birt
draws a chart on the printer image GC without any scaling/translation
and therefore - after drawing the image on the screen - out of my screen
boundaries exept the white background pane which is at its right place.
when setting the rendering boundaries to 0.14... of the previosly used
chart size, the drawing might be in the right place, but the fonts are
shown 0.14...^-1 times larger as they should be. When moving the
displayed area of the enlarged page the chart is drawn always in the
same position on the screen and doesn't move around with the rest of the
page (This is where the translation comes into play).

Enrico,

Can you open a bug for this?
