Animation Image (lv_animimg)

Overview

The animation image is similar to the normal 'Image' object. The only difference is that instead of one source image, you set an array of multiple source images.

You can specify a duration and repeat count.

Parts and Styles

LV_PART_MAIN A background rectangle that uses the typical background style properties and the image itself using the image style properties.

Usage

Image sources

To set the image in a state, use the lv_animimg_set_src(imagebutton, dsc[], num).

Events

No special events are sent by image objects.

See the events of the Base object too.

Keys

Simple Animation Image

A simple example to demonstrate the use of an animation image.

#include "../../lv_examples.h"
#if LV_USE_ANIMIMG && LV_BUILD_EXAMPLES
LV_IMAGE_DECLARE(animimg001);
LV_IMAGE_DECLARE(animimg002);
LV_IMAGE_DECLARE(animimg003);

static const lv_image_dsc_t * anim_imgs[3] = {
    &animimg001,
    & animimg002,
    & animimg003,
};

void lv_example_animimg_1(void)
{
    lv_obj_t * animimg0 = lv_animimg_create(lv_screen_active());
    lv_obj_center(animimg0);
    lv_animimg_set_src(animimg0, (const void **) anim_imgs, 3);
    lv_animimg_set_duration(animimg0, 1000);
    lv_animimg_set_repeat_count(animimg0, LV_ANIM_REPEAT_INFINITE);
    lv_animimg_start(animimg0);
}
