How to load image from memory instead of Harddisk (.NET)

[ETom]

Hi,

How can I load an image from memory into IMAQ format picture, not using the Harddisk.?

At this moment I save my picture (.bmp) to the harddisk and then open again via CWIMAQVision1.ReadImage(...)

As this is the only way I can make it work.

But this is not what I want. I would like to convert directly from RAM towards IMAQ compatible format.

All the examples I saw where using functions that use an actual pathname to harddisk.

Thanks,

Tom.

It depends.  The image in RAM in what form?  Do you have a handle of it?

If you have purchased the Vision toolkit, you can use IMAQ ArrayToImage.  The input is a 2D array of pixel intensities, and the output is an IMAQ image.

Without the toolkit, I don't think there is a way to bring in images from other sources.

Thanks,

I'll try the arraytoimage functionality.
I think we have the toolkit, but I'm not sure.

It's a .bmp format and yes I have a handle.
I try to cast it, but that didn't do the trick.

Many thanks,

Tom.

If you got the handle, you got the image.
To get pixels, you got to use Window API.
There is a VI on my website does this: Bitmap handle to Image Cluster
