how do you write text on 16 bit image

[Deanna Zhang]

I am trying to add text to my 16 bit image. The problem is that the IMAQ draw text vi does not draw on 16 bit images. Is there any other vi's or functions I can use to draw the text?

You can use the picture control VIs to do this. They are located in the palettes at...

Functions Palette >> Graphics & Sound >> Picture Functions

You'll want to convert the image to a picture then draw the text and then convert the picture back to an image...

Draw Flattened Pixmap.vi ==> Draw Text at Point.vi ==> Picture to Pixmap.vi

I don't think this will work because drwa flattened pixmap will only work for 1, 4, 8, or 24-bit true color depth and I need 16 bit grayscale (without loosing anything).
