IG_IP_swap_red

This function reverses the color sequence in the pixels of image hIGear's image bitmap.

Declaration:

	Copy Code
AT_ERRCOUNT ACCUAPI IG_IP_swap_red_blue ( HIGEAR hIGear);

Arguments:

Name	Type	Description
hIGear	HIGEAR	HIGEAR handle of image.

Return Value:

Returns the number of ImageGear errors that occurred during this function call.

Supported Raster Image Formats:

All pixel formats supported by ImageGear for C and C++.

Non-RGB images are converted to RGB for processing, and then back to original color space.

Sample:

Image Processing

Example:

	Copy Code
HIGEAR hIGear; /* HIGEAR handle of 24-bit image */ IG_IP_swap_red_blue ( hIGear );

Remarks:

If the sequence is Blue-Green-Red (the standard sequence for a DIB), it is reversed to Red-Green-Blue. If Red-Green-Blue, each pixel is reversed to Blue-Green-Red. This function is typically used on 24-bit RGB images, but it can operate on other image types as well.
