  • How to draw a filled gradient circle

    What is the best way to draw a filled gradient circle. I am currently using bmp images, but I wonder whether it would be possible to use simple emWin operations.
    I have not found any information regarding my question in the documentation. But I imagine that maybe using transparent windows and the drawing of gradient rectangles it is possible to achieve the same result.

    So, Is it possible to draw a filled gradient via simple drawing operations or the best way is the use of an image?

    Thanks.

  • Hi,

    Unfortunately, this is not possible with emWin.

    So, the best way is to create an circular gradient with e.g. GIMP and either use the PNG/BMP and draw it on the screen or convert it into an emWin bitmap using the BitmpaConverter and display it this way.
