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(imgbtn, dsc[], num).

Events

No special events are sent by image objects.

See the events of the Base object too.

Learn more about Events.

Keys

No Keys are processed by the object type.

Example
