Some more image object functions examples (2nd block)

In this example, we have three images on the canvas, but one of them is special – we're using it as a proxy image object. It will mirror the contents of the other two images (which are the ones on the top of the canvas), one at a time:

d.proxy_img = evas_object_image_filled_add(d.evas);
evas_object_image_source_set(d.proxy_img, d.logo);
evas_object_move(d.proxy_img, WIDTH / 2, HEIGHT / 2);
evas_object_resize(d.proxy_img, WIDTH / 2, HEIGHT / 2);
evas_object_show(d.proxy_img);
evas_object_show
EVAS_API void evas_object_show(Evas_Object *eo_obj)
Makes the given Evas object visible.
Definition evas_object_main.c:1814
evas_object_move
EVAS_API void evas_object_move(Evas_Object *obj, Evas_Coord x, Evas_Coord y)
Move the given Evas object to the given location inside its canvas' viewport.
Definition evas_object_main.c:1171
evas_object_resize
EVAS_API void evas_object_resize(Evas_Object *obj, Evas_Coord w, Evas_Coord h)
Changes the size of the given Evas object.
Definition evas_object_main.c:1236
evas_object_image_source_set
EVAS_API Eina_Bool evas_object_image_source_set(Evas_Object *eo, Evas_Object *src)
Set the source object on an image object to used as a proxy.
Definition evas_image_legacy.c:463
evas_object_image_filled_add
EVAS_API Evas_Object * evas_object_image_filled_add(Evas *eo_e)
Creates a new image object that automatically scales its bound image to the object's area,...
Definition evas_image_legacy.c:35

As in other examples, we have a command line interface on it.

static const char *commands = \
"commands are:\n"
"\tp - change proxy image's source\n"
"\ts - print noise image's stride value\n"
"\ta - save noise image to disk (/tmp dir)\n"
"\tv - change source visibility\n"
"\te - enable/disable source events\n"
"\th - print help\n";

The 'p' one will change the source of the proxy image to one of the other two, as seem above.

if (strcmp(ev->key, "p") == 0) /* change proxy's source */
{
Evas_Object *source = evas_object_image_source_get(d.proxy_img);
if (source == d.logo) source = d.noise_img;
else if (source == d.noise_img) source = d.text_obj;
else source = d.logo;
evas_object_image_source_set(d.proxy_img, source);
printf("Proxy image's source changed\n");
return;
}

evas_object_image_source_get
EVAS_API Evas_Object * evas_object_image_source_get(const Evas_Object *eo)
Get the current source object of an image object.
Definition evas_image_legacy.c:470

Note the top right image, the smaller one:

d.noise_img = evas_object_image_add(d.evas);
evas_object_image_size_set(d.noise_img, WIDTH / 4, HEIGHT / 4);
evas_object_image_data_set(d.noise_img, pixels);
evas_object_image_filled_set(d.noise_img, EINA_TRUE);
evas_object_move(d.noise_img, (WIDTH * 5) / 8, HEIGHT / 8);
evas_object_resize(d.noise_img, WIDTH / 4, HEIGHT / 4);
evas_object_show(d.noise_img);

Definition evas_image_legacy.c:610
evas_object_image_size_set
EVAS_API void evas_object_image_size_set(Evas_Object *eo_obj, int w, int h)

Definition evas_image_legacy.c:25
evas_object_image_filled_set
EVAS_API void evas_object_image_filled_set(Evas_Object *eo_obj, Eina_Bool value)
Set whether the image object's fill property should track the object's size.
Definition evas_image_legacy.c:81

Since we are creating the data for its pixel buffer ourselves, we have to set its size with evas_object_image_size_set(), first. We set our data with the function evas_object_image_data_set(), where the second argument is a buffer with random data. There's a last command to print it's stride value. Since its created with one quarter of the canvas's original width

#define WIDTH (320)
#define HEIGHT (240)

you can check this value.

The image on the top left also has a subtlety: it is pre-loaded on this example.

d.logo = evas_object_image_filled_add(d.evas);
evas_object_event_callback_add(
d.logo, EVAS_CALLBACK_IMAGE_PRELOADED, _on_preloaded, NULL);
evas_object_image_preload(d.logo, EINA_TRUE);
