The cpdf_import_jpeg() function
opens an image stored in the file with the name file name. The format of the image
has to be jpeg. The image is placed on the current page at
position (x-coor, y-coor). The image is rotated
by angle degrees.
The optional parameter
mode determines the unit length. If it's 0 or
omitted the default unit as specified for the page is used.
Otherwise the coordinates are measured in postscript points
disregarding the current unit.
