Image: Adjustments: Invert
Invert image color
1. imgInvert oimg:=<new>;
2. imgInvert img:=mat(1) oimg:=mat(2);
Specifies the source image to be manipulated. The default input is the active image.
Specifies the output image. By default, the output image is the same as the input image.
See the syntax here.
The imgInvert function inverts the colors in the specified bitmap, making it like a photographic negative. This function can also be used to invert the color of a 1-bit image, making the black white and the white black.
In this example, we use the imgInvert function to invert the color of the input image:
For gray scale image,
O(x, y) = - I (x, y);
For color Image,
where O(x, y) is the output pixel value, I(x, y) is the input pixel value, and Bits is Bits Per Pixel.
The computation uses L_InvertBitmap() function from LEADTOOLS Main API. Please refer to the LEADTOOLS Main API Help file, Version 14 and read the L_InvertBitmap topic.
