Overview
This SubVI takes in the percentage of Red, Green, and Blue from an image and creates a Color Map that can be applied to any 8 bit image using Flatten Pixmap.
Description
The Create Color Map.vi creates a scaled color mask that is applied to the 8-bit BMP image file's color properties. By using a scaled color percentage for Red/Green/Blue, which are found by converting each vaule to an 8-bit unsigned integer, ranging from 0-255, the values are returned as a 1D array of colors. This array, is then fed into the image data colors element of the Bundle by Name, and it is then flattened into a pixmap for image display.
Caveats and Additional Notes
Color Maps will not work on 24+ bit images.
Steps to Implement or Execute Code
- Specify the path to your desired 8-bit BMP file on the Color Map Demo.vi Front Panel
- Run the VI
- Change the RGB percentage sliders to manipulate the image
Requirements
Software
