Abstract
OpenOffice Draw currently exports all bitmap file formats in 96 DPI resolution. This resolution is insufficient for use with bitmap editors or for printing. Since a vector editor like OO Draw cannot perform free-hand paint operations (eg. random airbrushing, erasing, etc) the images it produces are necessarily very limited in scope. Simple object gradients do not replace this need.
The purpose of any export function is to allow integration with other programs. True integration would allow a user to compose, size, and maintain a vector quality drawing in OoDraw, and yet export an instance of it for specialized freehand manipulations by a bitmap editor in a final presentation graphic.
The only stumbling block is Draw's present 96 DPI export resolution. This specification would change that resolution to a maximum of 600 DPI, for a maximum file size to accommodate the US Letter and A4 formats.

Detailed Specification
- Maintain the present default of 96 DPI for file exports.
- Reason: to minimize normal export file size, reduce bit calculation time, and to allow screen graphics to be exported without additional user intervention.
- Offer additional user selectable resolutions of 150 DPI, 200 DPI, 300 DPI and 600 DPI for document sizes up to US Letter and A4.
- Documents larger than USL and A4 will export at the default (96 DPI) resolution.
- Input the user's resolution preference in the main Format menu via an item labeled “Export Resolution...”
- Clicking on that menu item opens a combo box with the following items displayed:
Resolution (DPI) input field – choices for: 96, 150, 200, 300, 600 Resolution (Dpcm) calculated field or display only Pixels (Horiz.) calculated for display Pixels (Vert.) calculated for display Image size (uncompressed) calculated for display Default button --> resets Resolution to 96 DPI
