You find the item Drawing Pad as Picture in the File menu, Export. Here, you can specify the scale (in cm) and the resolution (in dpi) of the output file. The true size of the exported image is shown in the bottom of the window.
Choose out of the following formats:
PNG graphic files are well suited for the use on web pages (html) and with Microsoft Word. Whenever you insert a PNG graphic file into a Word document (menu Insert, Image from file) make sure that the size is set to 100%. Otherwise the given scale (in cm) would be changed.
The resolution of an EPS graphic is always 72dpi. This value is only used to calculate the true size of an image in cm and has no effect on the image's quality.
Note: the transparency effect with filled polygons or conic sections is not possible with EPS.
