Where can I find the numerical value for GenICam standard pixel formats?

I am putting in place a structure of case for the reconstruction of image formats using the pixel as IMAQdx output format. Confirmed the consistent property of 'Pixel Format' numeric U32 in id IMAQdx from camera to camera, but it's just a number, and I don't see that the number of image formats used by the cameras I (I need code for other formats I've yet to see). The GenICam standard 1.1 supports 52 image formats, and no doubt IMAQdx has a corresponding U32 value for each format. Where can I find this list? The .pdf for the GenICam standard lists the formats available in name only and does not have a corresponding numerical value.

Hey Nasgul

The attribute 'PixelFormat' is actually a list of name/value pairs. For GenICam cameras (such as GigE Vision) these names and these values are determined by the camera, no IMAQdx XML file. The names themselves are normalized by the part of the "Standard feature Naming Convention" of GenICam (but aren't their values).

I think you speak for the Format of Pixel property node. I think you are right that it is a digital. It's probably because the available modes can not be known before you actually run the code and the LabVIEW enumeration values must be known when editing, no compilation. The node itself as a digital is probably as a relic of the firewire interface. It would be probably more useful as a string, I imagine.

You probably want to use the generic way of manipulating the attributes instead. You initially set the property 'Attribute Active' in 'PixelFormat' and then you can then query a list of name/value pairs available or simply set the value. IMAQdx allows you to set the value directly as a string (using the standard names) rather than having to translate it into a numeric value.
