Divides one image by another image or an image by a constant.

image src a

Reference to the first source image.

image dst

Reference to the destination image.

If connected, image dst is converted to an RGB image. If not connected, image src is converted to an RGB image.

image src b

Reference to the second source image.

constant

Value that dividesimage src a for image-constant operations.

constant must be a RGB color value when image src a is a color image.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error	error in contains an error

If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

rounding mode

Type of rounding to use when dividing image pixels.

Name	Description
optimized	Rounds the result of a division using the best available method.
truncate	Truncates the result of a division.

image dst out

Reference to the destination image that receives the processing results of the node.

If image dst is connected, image dst out is the same as image dst. Otherwise, image dst out refers to the image referenced by image src a.

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

error in does not contain an error	error in contains an error

If no error occurred before the node runs, the node begins execution normally. If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.	If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Image Type Behavior

The image type of image src b depends on the image type of image src a.

If image src a is a signed 16-bit image, image src b must be a signed 16-bit image or an unsigned 8-bit image.
If image src a is a 32-bit floating-point image, image src b must be a 32-bit floating-point image, signed 16-bit image, or unsigned 8-bit image.
If image src a is a complex image, image src b must be a complex image, 32-bit floating-point image, signed 16-bit image, or unsigned 8-bit image.
If image src a is a 32-bit RGB image, image src b must be a 32-bit RGB image, complex image, 32-bit floating-point image, signed 16-bit image, or unsigned 8-bit image.
If image src a is a 64-bit RGB image, image src b must be a 64-bit RGB image, 32-bit RGB image, unsigned 16-bit image, or unsigned 8-bit image.

Otherwise, image src b must be the same type as image src a.

When the value of a pixel in image src b is 0, the result of the divide operation for the pixel is either the maximum or minimum pixel value for the image type. If the corresponding pixel value in image src a is greater than 0, then the result is the maximum possible pixel value for the image type. Otherwise, the result is the minimum possible value for the image type.
