  • Draw Gradient

    Hello, using draw gradient functions don't work very well. They draw various colored small bar in the way of function. First and end color are good but there is a middle yellowish color.
    I use stm32f7 driver.
    Thanks.

    Regards,
    Sven

  • Conversion color is GUICC_M8888I with LIN32 driver.
    Image quality is bad. Gradient color is white to black. We can see brown bar colored.
    I write a simple gradient function in a for loop and GUI_DrawHLine(), black to red colors and it's work well.
