Hi Guys,
I am writing a VI will when run, will enable me to rotate an image. Right now this is what I am working on:
1. Image -> Pixmap (using Picture to Pixmap VI)
2. Pixmap -> 2D array (using Unflatten Pixmap VI)
3. 2D array to -> Pixmap (using Flatten Pixmap VI)
4. Pixmap -> Picture (using Pixmap to Picture VI)
The problem I am facing is that if my picture has in it "Hello", the output is hello, yet the background fill of the picture has gone from the original colour (transparent) to black. I was wondering why this occurs, especially since I'm not rotating the picture as of yet, there shouldn't be a change in the pixels.
Further investigation leads me to think that there might be something in last stage of the processing (stage 4). I am attaching the VI in question. Hope some one can point me in the right direction.
Regards,
