avl.dll with Labview

[akang]

I have some code from previous programer using the library avl.dll.  ( the three functions of AVI_Write, AVI_Init, AVI_Close)

I find that the image saved and the image acquired is different in the gray level.

Could anybody tell me what these functions do exactly?

Is there a document describing these functions in detail?

Thanks

Hello,

Those functions do not appear to be National Instruments supplied functions.  I would suggest that you contact the developer that you inherited that code from to find out where that DLL came from.  What programming environment are you using and how are you acquiring the images that you are working with?  There are several NI-IMAQ functions that you could use if you are working with an NI framegrabber board to obtain images. 

Try downloading and installing that software and let me know if you have any additional questions.
