I’m not sure if making the canvas transparent is possible in v6. If the buffer is chroma keyed, try filling it with LV_COLOR_TRANSP. If that still doesn’t work, you may have . static lv_style_t style; style.body.main_color = LV_COLOR_ORANGE ; style.body.grad_color = LV_COLOR_ORANGE; lv_obj_set_style(lv_scr_act(), &style); In the image creation function. void f() { static lv_style_t style; lv_style_copy(&style, &lv_style_transp); //style.image.intense = LV_OPA_70; style.image.intense = LV_OPA_TRANSP; .
The problem appears when opacity of widgets on top needs to be changed to a value that isn’t 255 - everything that isn’t 255 is treated as 0. If I understand correctly, in order to make possible, LV_COLOR_SCREEN_TRANSP needs to be set to 1 - as we are drawing on top of widgets with transparent backgrounds.

Colors. The color module handles all color-related functions like changing color depth, creating colors from hex code, converting between color depths, mixing colors, etc. lv_color_t is used to store a color, its fileds are set according to LV_COLOR_DEPTH in lv_conf.h. (See below) To enable this feature set LV_COLOR_SCREEN_TRANSP 1 in lv_conf.h. After it the screen can have opacity.The color module handles all color-related functions like changing color depth, creating colors from hex code, converting between color depths, mixing colors, etc. The type lv_color_t is used to store a color in RGB888 format.
I have a simple lvgl example which runs on an embedded device. It should work like an Overlay on top of an existing image. In this case, I only want to render the text of the label thus the label and the screen should have a transparent background. My approach is to set.
The object does not takes up the whole screen. When the object is drawn to the screen, the background is always white. Is there a way to make the background of the screen transparent? The color space used is argb and the "a" is always the same value (0xff) regardless of the transparency set. If the screen is transparent too than LittlevGL stores the alpha value of the shadow pixels in the alpha channel of ARGB888 colors (LV_COLOR_SCREEN_TRANSP needs to be enabled to work like this). However, if you have only 1 bit alpha it’s not possible. It seems your best option is not to use shadows.Part of the LV Sea Treasure capsule, the Treasure Box bag is made from Monogram satin, entirely covered in hand-applied translucent crystals, evoking water droplets.
