notIm ( integer Input, integer Output )

Use this function to perform a bitwise logical "NOT" on pixel values of an image or selection. Every bit that has a value of "1" will be set to "0" and vise versa. Applied to a binary image this function will reverse the foreground and background.

Parameters
 
Input  
 
An integer between 0 and 116 specifying the input image frame number. A value of 0 represents the DMA memory buffer of the video device. Values in the range of 100-116 correspond to hidden frames.  
 
Output  
 
An integer between 1 and 116 specifying the output image frame number. Values in the range of 100-116 correspond to hidden frames.  
 
Error flags

ERR_OK  
 
The flag set if successful.  
 
ERR_FAILED  
 
The flag set if failed.  

Example

This set of statements performs the "NOT" operation on a sample image:  
 
setCurDir("samples")  
loadIm (1,"sample7.iwd")  
notIm (1,2)  
 
Remark
 
Floating and complex images cannot be processed by this function.
