Hi Sir
I used Fg_getParameterPropertyEx to get DMA width like below
There were 4 DMA ,and I set the property dmaIndex of Fg_getParameterPropertyEx to 3.
Fg_getParameterPropertyEx return an error code -2070.
What's wrong about the input parameters?
Runtime version : 5.7.0
Thank you.
Jesse
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.
