Read BMP File VI (32-bit bitmap)

[J Mazzetta]

It appears that LabView does not support 32-bit bitmaps...
I would like to use the Read BMP File VI but the bit depth is limited to 1, 4, 8, or 24.

Does anyone know of a workaround or any plans of NI to support this relatively new graphics format?

The NI Vision Software supports 32 and 64 bit BMPs.  Don't know what comes with LabVIEW without Vision.

IMAQ ReadFile

Reads an image file. The file format can be a standard format (BMP, TIFF, JPEG, JPEG2000, PNG, and AIPD) or a nonstandard format known to the user. In all cases, the read pixels are converted automatically into the image type passed by Image.

Take a look Image Toolbox at:

I took a look at the help for Read BMP File and it says: "image depth specifies the color depth of the image, which is the number of bits to use to describe the color of each pixel in the image. Valid values include 1, 4, 8, and 24 bits per pixel. image depth affects how LabVIEW interprets the values of image and colors." so not sure if it can read 32-bit RGB.  i will try to find a 32-bit RGB to try it on.

From my understanding a 32-bit bitmap is a relatively new image file format that contains the standard 24-bit data (8-bit Red, 8-bit Green, 8-bit Blue) with an additional 8-bit Alpha Channel used to define image transparency...
