Elementary photocam widget
This snippet shows how to create a photocam widget and use it's basic features (zoom, bounce). Photocam is used for working with big image files.
//icon directory should look like this
#define IMG_DIR "/opt/usr/apps/org.example.myapp/res/images"
static void photocam_test(Evas_Object *parent) {
//create photocam object
Evas_Object *photocam = elm_photocam_add(parent);
elm_win_resize_object_add(parent, photocam);
//set source file (a big image file)
char path[100] = { 0 };
snprintf(path, sizeof(path), IMG_DIR"/%s", "big_image.jpg");
if (!elm_photocam_file_set(photocam, path)) {
dlog_print(DLOG_ERROR, LOG_TAG, "Unable to load photocam!");
}
//enable scroller bouncing
elm_scroller_bounce_set(photocam, EINA_TRUE, EINA_TRUE);
//fit the image to parent's size
//elm_photocam_zoom_mode_set(photocam, ELM_PHOTOCAM_ZOOM_MODE_AUTO_FIT);
//manual zoom control
elm_photocam_zoom_mode_set(photocam, ELM_PHOTOCAM_ZOOM_MODE_MANUAL);
//set zoom, here the photo will be 2 times smaller than original
//values can be <1, then we'll make photo larger than original
elm_photocam_zoom_set(photocam, 2);
evas_object_show(photocam);
