Matrox MIL-Lite with IPL

[New developer]

Hi,
I am using Matrox-Meteor II and want to use IPL to process images
captured with it. I am not sure how to do this. I found we can create
device independent bitmaps with Mil-lite and take a pointer to this
which can be used to create an iplImage. But I am having a trouble
with this...

Specifically I have this piece of code..

numBands = 3;
Height = 240;
Width = 384;
depth = 8;
BITMAPINFO bitMap;
MbufAllocColor(MilSystem,numBands,Width,Height,depth +
M_UNSIGNED,M_IMAGE+ M_GRAB + M_DIB ,&MilColorImage);
MdigGrab(MilDigId, MilColorImage);
MbufInquire(MilColorImage,M_WINDOW_DIB_HEADER,&bitMap);

But I am never getting any data in the bitMap structure.

1. Is this the correct way to do the intended?
2. If yes, what might be going wrong? ( I have also tried changing the
milsetup.h but it did not work).

Use MbufGet (or is it MbufPut?) to put your video frame data into an array
you created.
Then use the IPL functions to fill an IPL allocated image with the data from
the array.
You can then process your IPL image.
This is cumbersome and slow but it works. It is faster if you copy the array
line by line into the IPL image

Try the following example, it has been verified with MIL-Lite 6.1 and
7.1:

void main(void)
{
MIL_ID MilApplication, MilSystem, M_NULL, MilDigitizer, MilImage;
BITMAPINFO bitMap;

MappAllocDefault(M_SETUP, &MilApplication, &MilSystem, &MilDisplay,
&MilDigitizer, M_NULL);
MbufAllocColor(MilSystem, 3, 640, 480, 8+M_UNSIGNED,
M_GRAB+M_DISP+M_IMAGE+ M_DIB, &MilImage);
MdigGrab(MilDigitizer, MilImage);
MbufInquire(MilImage, M_WINDOW_DIB_HEADER, &bitMap);
printf("%d.\n", bitMap);
printf("Press <Enter> to end.\n");
getchar();
MappFreeDefault(MilApplication, MilSystem, M_NULL, MilDigitizer,
MilImage);
}
