Where there is no strong reason to choose another image file format, you should use SVG or PNG file formats in DITA topics.
DITA supports a variety of image formats. A more accurate assertion is that you can place a reference to any sort of image file inside a DITA image element, and it will be up to the publishing processor as to whether this image can be handled and generated into a reading format.
Unless you have specific reasons for choosing other formats, you should use SVG for line drawings and diagrams. Likewise, for photographs, use JPG with zero or low compression, particularly if you will be publishing to print formats. For other purposes, you should prefer PNG. If your publishing process does not support SVG, you may have to use PNG instead. However, a better approach is to use a publishing process which supports SVG.
