Showing png image error

How-to
3

Image data source:
const lv_img_dsc_t png_decoder_test = {
.header.always_zero = 0,
.header.w = 200,
.header.h = 150,
.data_size = 20869,
.header.cf = LV_IMG_CF_RAW_ALPHA,
.data = png_decoder_test_map,
};

test code :
png_decoder_init();

LV_IMG_DECLARE(png_decoder_test);
lv_obj_t * img = lv_img_create(lv_scr_act(), NULL);
lv_img_set_src(img, &png_decoder_test);

Now it is located that there is a problem with memory allocation, error code 83, application memory allocation failed. Which method I use in your blog, the source of the image data I use is also there. What should I do? Thank you
