  • MemDev, flickering GIF images

    Hello,

    I created a simple dialog consisting of 2 button widgets, some image widgets (with a gif) and a text widget.

    Pushing buttons changes the value of the Text widget. However, in some cases this lead to flickering.

    Adding:

    Source Code

    1. #if GUI_SUPPORT_MEMDEV
    2. WM_SetCreateFlags(WM_CF_MEMDEV);
    3. WM_EnableMemdev(WM_HBKWIN);
    4. #endif



    solved the flickering issue, however, now the gifs won't show up.

    If I change the gifs to BMP's they do show up (in guibuilder ->assign BMP instead of gif).

    Any tips? I'd prefer GIF's for easy transparancy!

    Thanks.

    Steven

  • Hello Adrian,

    I've included my main file and the window created by the gui builder. I've also taken 2 pictures: 1 with WM_EnableMemdev(WM_HBKWIN) and one without WM_EnableMemdev(WM_HBKWIN).

    If you wish I can send the complete code, it's not closed source.

    Best regards & thanks for any tips.

  • Hello Steven,

    Thank you for sending the code. Unfortunately I am not able to compile. Would it be possible for you to provide me with the least required code which shows the problem and enables me to run in the the emWin simulation environment? Thank you.

    Best regards,
    Adrian

  • Hello Adrian,

    I've tried duplicating this behavior in the simulator, but everything works fine in the simulator, but not on the target hardware.

    I've attached the code that I used to test on the simulator, and also a movie of what happens on target hardware.

    I've allocated 64 kBytes of memory so I'm fairly certain that should be sufficient for a 300 X 50 pixel GIF.

    Change the gif to a bitmap and everything works ?) Using STemwin 5.26

    Tips are welcome :)
