  • PNG draw queries

    Hi Segger,

    Please clarify queries below

    In our setup, we have Cortex M4 running at 72 Mhz, using GUIDRV_Lin_16, LCD is -> 120x120,
    We are drawing a PNG using, GUI_PNG_Draw. We see that this is taking 220ms to draw(LCD Frame transfer time is 12.5ms only)

    Could you explain, why the draw takes this much time ?
    1. What are the possible options to accelerate/optimize PNG draw operations ?
    2. What is the better way enable animations. PNG file as bin or PNG as bitmap ?
    3. Can the alpha color mixing be optimized ?
    4. How much MIPS does PNG draw require ?
