Description apienk01 2004-07-28 12:50:04 UTC 
Currently, drawings can be exported to bitmaps only at the default resolution of
computer screen. In BMP export there is the option to set DPI, but it doesn't
work as it should - the bitmap produced has the same size in pixels regardless
of the DPI setting. Normally, if 300 DPI (print quality) is chosen instead of
standard 75 DPI of the computer screen, the bitmap should be four times bigger
in width and height, measured in pixels - because the physical size of the paper
(in centimetres or inches) doesn't change, and there are more bitmap pixels per
inch (DPI). Please make this work, as this should require only a small change in
rasterization routines.

If this would not work like it should it would be a defect and not an
enhancement.  Referring to bug 32202 which you wrote earlier: please give me
more details on how you find out the dpi count of the exported files. Thanks.
Comment 2 apienk01 2004-07-28 13:26:03 UTC 
OK. Let's say I'm creating a business card, 3.5 inches wide and 2 inches high,
and want to export it to bitmap for printing at 300 DPI. This means that the
final bitmap should be 1050x600 pixels, because at 300 DPI the printer has to
put 300 full-color dots on one inch. When I export my business card from OOo
Drawing as BMP bitmap, setting the 300 DPI option, I get an image that has a
resolution of 336x192 pixels. When I check the DPI in a graphics viewer, it is
at 300, but the physical width is not 3.5 inches anymore!

Hi,
sorry for the long answering time, but due to too much work I was stressed out a
little bit.

In general everything is already said in Issue 4499.
