bmp to 2D Array

[Simon790]

Hello

I'm trying to convert an bmp-File into a 2-d array which should conatin the values of each pixel. I created this VI but it doesn't work. Could somebody tell me why not?

Thanks

Simon

PS: I succesfull created the opposite. A VI which creates a bmp out of a 2d array. Now I failed to do it vice versa 😞

You are writing a 24 bit pixmap, but then try to read a 8 bit pixmap. The two must match.

(You should also try to use the correct datatypes)

Simon,

Your VI works for me. Are you sure the .bmp file you are trying to read has 24-bit data? Put an indicator on the image data cluster coming from the Read BMP File VI and see what it says. Also check the error out cluster to see if any errors are reported. I used the file at LabVIEW 8.0 >> Examples >> General >> dragdrop >> 0.bmp as a test file.

Sorry, I was in a hurry and wrote it backwards.

You are writing an 8 bit image, but read it as a 24 bit image. Check the connectors.

Yes, now it works. Thank you very much!
