imgfont can't display

[rayden]

 

Gui Guider-1.8.1-GA

The type I used is lable and the text content is "abcdefg".

SVG images were used to generate the font, but it doesn't show up after compiling with GUI guider. Why is that?

The TTF files generated from single-color SVG images can be displayed, but those generated from multi-color SVG images cannot be displayed.

Hi @rayden 

Can you try using different SVG fonts to see if the problem still persists？

hi@Harry_Zhang  

The version I am currently using is lvgl8.3.

I referred to 'https://lvgl.100ask.net/8.3/others/imgfont.html',However, my icon was not displayed on the screen.The attachment is the array file generated by my image processing program.How can I make it displayed in lvgl8.3 on my device?

// code start 

LV_IMG_DECLARE(img_bluetooth_31);

static bool get_imgfont_path_lefticon(const lv_font_t * font, void * img_src,

                             uint16_t len, uint32_t unicode, uint32_t unicode_next)

{

    LV_UNUSED(font);

    LV_UNUSED(unicode_next);

    LV_ASSERT_NULL(img_src);

    if(unicode == 0xF617) {

        memcpy(img_src, &img_bluetooth_31, sizeof(lv_img_dsc_t));

    }

    return true;

}

void lv_imgfont_lefticon_task(void)

{

    lv_font_t * imgfont = lv_imgfont_create(55, get_imgfont_path_lefticon);

    if(imgfont == NULL) {

        LV_LOG_ERROR("imgfont init error");

        return;

    }

    imgfont->fallback = LV_FONT_DEFAULT;

    guider_ui.mainscreen_label_icon_left = lv_label_create(guider_ui.mainscreen);

    lv_label_set_text(guider_ui.mainscreen_label_icon_left, "\uF617");

    lv_obj_set_style_text_font(guider_ui.mainscreen_label_icon_left, imgfont, LV_PART_MAIN);

    lv_obj_set_pos(guider_ui.mainscreen_label_icon_left, 0, 0);

    lv_obj_set_size(guider_ui.mainscreen_label_icon_left, 785, 80);

    lv_obj_set_style_text_color(guider_ui.mainscreen_label_icon_left, lv_color_hex(0x666666), LV_PART_MAIN);

}
