CUDAImageMultiply

multiplies an amount x to each channel value in img.

multiplies an amount x to each channel value in mem.

gives an image in which each pixel is the product of the corresponding pixels in

and

gives a CUDAMemory in which each pixel is the product of the corresponding pixels in

and

MORE INFORMATION

The CUDALink application must be loaded using Needs.

works with binary, grayscale, and other images.

works with CUDAMemory and lists.

is equivalent to ImageMultiply and CUDAImageDivide.

The image returned by has the same dimensions as image.

and must be the same dimensions in .

If is a single-channel image, each channel of is multiplied by in .

In , the number x is normally in the range 0 to 1.

gives an image with the same underlying data type as image, clipping or truncating values if necessary.

gives an image with the type of , clipping or truncating values if necessary.

The following options can be given:

	"Device"	Automatic	device used for CUDA computation
	"OutputMemory"	None	CUDAMemory where output is stored
