Select the width and height you need in inch or cm ... the size you want to be printed on paper for example... then select the dpi ...Vue will calculate the width and height in pixels.... take care that your printer can print in such a resolution to obtain the right size ... For example, when you want to publish a picture, the professional standard is mostly 300 dpi ( this is a printing standard, not an 'on screen' standard ) ..... You only have to choose the width and height in cm or inch ... and the dpi. I don't really understand what you mean with Poser ...
