Fg_getParameterPropertyEx [error code -2070]

  • Hello Jesse,


    which exact information do you want to get from the frame grabber?


    1. Is it the link property Max. Img Width of DMA 3 in VisualApplets?

    2. Is it the actual image width of the last image transferred over DMA 3?

    3. Is it the number of byte of the last image transferred on DMA 3?

  • Hi Johannes


    It is the link property Max. Img Width of DMA 3 in VisualApplets.


    I create a class for storage parameter properties and need get the all properties of Width .

    So I used Fg_getParameterPropertyEx to get value,range,access..etc.

    When I get those properties, I will allocate memory by those properties.

    About question 3. Is it the number of byte of the last image transferred on DMA 3?

    When I used blob operator, it will output uncertain length.

    I used SisoImage.getPixelCount to get the number of byte of the last image transferred on DMA in C# wrapper.

    Is it correct?


    When I used getPixelCount ,it always return 0.
