|

level=0 is maximum scanner surface,
|
|
<BR>
|
|
level=1 is reduced scanner surface, subpart of level 0
|
|
<BR>
|
|
level=2 is zoomed area, subpart of level 0 and 1
|
|
<BR>
|
|
<P>quality = preview_restore_image_from_file(p, in, quality);
|
|
<BR>
|
|
loads the given file when:
|
|
<BR>
|
|
- it covers the area that has to be shown in the preview window
|
|
<BR>
|
|
- it has a higher quality than a possibly already loaded image
|
|
<BR>
|
|
<P>It does not display the complete image, it only uses the wanted subpart.
