Draw Text in an Image
Print
The following examples ship with Vision:
LabVIEW:
+ 2. Functions\Image Management
- Draw Text.vi
CVI:
+ 2. Functions\Image Management
- Draw Text.prj
VB:
+ National Instruments\Vision\examples\MSVB\2. Functions\Image Management
- DrawText.vbp
The IMAQ Draw and IMAQ Draw Text functions make permanent changes to an image, which is different than overlays.
The first example draws color objects on an image. Because the IMAQ Draw functions change the pixel values of an image, to draw color objects on your image, you must have a color image datatype and not a 8-bit monochrome image. The example below illustrates how to draw color objects on images.
