5 * @defgroup Photocam Photocam
7 * This is a widget specifically for displaying high-resolution digital
8 * camera photos giving speedy feedback (fast load), low memory footprint
9 * and zooming and panning as well as fitting logic. It is entirely focused
10 * on jpeg images, and takes advantage of properties of the jpeg format (via
11 * evas loader features in the jpeg loader).
13 * Signals that you can add callbacks for are:
15 * "clicked" - This is called when a user has clicked the photo without dragging
17 * "press" - This is called when a user has pressed down on the photo.
18 * "longpressed" - This is called when a user has pressed down on the photo for
19 * a long time without dragging around.
20 * "clicked,double" - This is called when a user has double-clicked the photo.
21 * "load" - Photo load begins.
22 * "loaded" - This is called when the image file load is complete for the first
23 * view (low resolution blurry version).
24 * "load,details" - Photo detailed data load begins.
25 * "loaded,details" - This is called when the image file load is complete for the
26 * detailed image data (full resolution needed).
27 * "zoom,start" - Zoom animation started.
28 * "zoom,stop" - Zoom animation stopped.
29 * "zoom,change" - Zoom changed when using an auto zoom mode.
30 * "scroll" - the content has been scrolled (moved)
31 * "scroll,anim,start" - scrolling animation has started
32 * "scroll,anim,stop" - scrolling animation has stopped
33 * "scroll,drag,start" - dragging the contents around has started
34 * "scroll,drag,stop" - dragging the contents around has stopped
38 * TODO (maybe - optional future stuff):
40 * 1. wrap photo in theme edje so u can have styling around photo (like white
43 * 3. rotation flags in exif handling (nasty! should have rot in evas)
