display error with indexed image #43

Closed fo2w closed 2 years ago

fo2w commented 2 years ago

branch: master

code to reproduce:

    // img_name_map is a c_array here with raw data
    // I random pick a PNG file and use the online tool (https://lvgl.io/tools/imageconverter) to generate it

    const lv_img_dsc_t img_name = {
      .header.cf = LV_IMG_CF_INDEXED_4BIT,
      .header.always_zero = 0,
      .header.reserved = 0,
      .header.w = 40,
      .header.h = 40,
      .data_size = 864,
      .data = img_name_map,
    };

    LV_IMG_DECLARE(img_name);
    lv_obj_t* icon = lv_img_create(lv_scr_act());
    lv_img_set_src(icon, &img_name);
    lv_obj_set_size(icon, 40, 40);

expected result: show the CORRECT image on the top left of the main window

actual result: image

Is it related to the windows port or LVGL in general?

EDIT: it works for me in Eclipse with the latest LVGL.

I have reproduced the issue and solved it by updating the LVGL version to the latest.
