Several vector formats such as WMF, CGM, DXF and HPGL do not support cropping. This is the act of cutting away and discarding the unnecessary portions of the picture such as extraneous fills and other elements. PDF and PostScript, both very robust and complete formats, do support it. To bridge the gap, Visual Integrity has developed a proprietary method to simulate cropping. When applied during conversion, the resulting file will appear cropped just like the original.
To apply it, select the “Emulate PS/PDF cropping” feature in the General tab of the Options menu.
