file “lvgl\src\draw\lv_img_buf.h” has following 2 lines
uint32_t w : 11; /Width of the image map/
uint32_t h : 11; /Height of the image map/
This means the max width/height of the image map is 2048.
file “lvgl\src\extra\widgets\chart\lv_chart.h” and “lvgl\src\extra\widgets\chart\lv_chart.c” have following line:
void lv_chart_set_div_line_count(lv_obj_t * obj, uint8_t hdiv, uint8_t vdiv)
This means the max chart div line count is 256.
I think the above 2 limits are unreasonable, the max value is too small. Could you increase the bits of these 2 values?
