Exporting to PNG with different dpi
The most common way of presenting SVG drawings created using Inkscape is by exporting them to PNG (Portable Network Graphics) format. This recipe will show us how this is accomplished and what to look out for, in particular when it comes to exporting the same drawing size (width and height in absolute units like inches) into a picture with a different dpi value. We will also use two of the images we export here in the following recipe, in order to practice importing of images with different dpi.
