Do you know what the upper size of the bitmap can be? If I make it really small it works, but over a certain size it just shows as a black box. I haven't quite narrowed down the size that breaks.

well, bmp images are loaded into ram, so you need at least enough ram

Hello,

it seems that in the XLS file in the GamebuinoPalette.zip file describing the colors, PINK (from the source) is called MAGENTA.

The section "Flash Image" explains how to do that. If you are still confused, would you please mind saying more specifically where you are stuck?

In the conversion tool linked. if you specified "indexed" it'll be uint8_t, else it'll be uint16_t.

Indexed images use a palette, by default the gamebuino palette. They are smaller in size.

RGB565 images are basically full color.

Is there a way to delete the images in ram (when i no more need them)

Sorunome

2 years ago

If the image object is deleted then the associated ram buffer is deleted, too.

Deletion of that happens e.g. if they are scoped locally or with the delete keyword, in case of pointers

void someFunc() {
    Image img(/* blah *);
    // do stuff

    // image gets deleted as it is end of the function
}
Image* img_ptr;

void init() { img_ptr = new Image(/* stuff */); } // later on in your code delete img_ptr;


Please note that that can easily cause ram fragmentation
