Rotating a picture

[Mtronic]

Hi everybody, I'm trying to use this NI example but I don't know how to change the plane that appear when I run the program. I know that comes from the part "airplane image" but don't know how use other image instead of this.

Thank you.

Hi Mtronic,

The airplane image in this example is stored explicitly in the airplane image array as a 24-bit pixmap. In order to substitute the airplane with a different image, you would first need to represent the new image as a 2D pixel array. This can be accomplished using the unflatten pixmap VI in some applications, although the entire Graphics Formats VIs palette may be of use to you, depending on the format of the image you wish to use.

Here are some other resources that may be helpful:

Best,

If you don't mind a .Net dependency (meaning Windows only) I wrote something that can rotate just about any picture, of any file format type, bitness, and supports alpha layers, by a pivot point, and degree, along with window scaling, and its pretty fast.

That whole thread has some good solutions too but mine works with just about any file type you can give it so it is the most developer friendly.
