[LVGL] Image scale fix for LVGL version 8.4.0

[gonit-dev]

I hope that in the latest version there will be an improvement in image scaling, where when the image is scaled it will be cut off, for example, I have an image of 1080x756px and I scale it to 50 in eez studio, the result is that the bottom part is cut off.

Do you mean in LVGL Image widget? There are different ways you can do it. For example:

You can also use "Inner align" with "STRETCH" option.

Actually, I encountered the same problem several versions ago. On the one hand, there is no "Inner align" in my property bar. On the other hand, after manually defining Width and Height, the image display will be cropped and incomplete.

Okay, I understand. There is no "Inner align" in LVGL8, and this is not a bug. However, abnormal cropping of images does occur in LVGL8.

I just found out that in LVGL 8.4.0 there is a function lv_img_set_size_mode with two options: LV_IMG_SIZE_MODE_VIRTUAL and LV_IMG_SIZE_MODE_REAL. The second one is what you need:

Property "Size mode" will be added in 0.26.1 release. This property only exists in version 8.4.0.
