## 5.4 Image objects

Images are inserted using the Insert image function in the File menu. Once in a drawing, you can scale, stretch, and rotate an image. You can read in some scanned drawing and draw on top of it within Ipe. This is useful if you have a drawing on paper and want to make an Ipe version of it.

Note that there are two separate functions for inserting JPEG images and inserting "other" images. JPEG images are literally included in the PDF output (using PDF's `DCTDecode` filter). "Other" images are stored as a pixel array, using Flate compression. Note that on some systems the function for "other" images will also accept JPEG files--obviously, the resulting PDF files will be (much) larger than if they had been included as JPEG images.

Images are stored most efficiently in PDF format. It is reasonable to create PDF presentations with lots of JPEG photographs in Ipe. Saving in Postscript is somewhat less efficient, as Ipe generates clean 7-bit Postscript files.

Note that images often appear on the screen with reduced resolution to ensure fast display updates--they are saved with full quality in the PDF/Postscript output. You can adjust the quality of the screen preview in the Preferences.
