Array to Image (G Dataflow)

Last Modified: October 24, 2017

Creates an image from a 2D array.

Each image pixels input is specific for a particular type of image.

Refer to the additional nodes in the node group for performing array-to-image transformations with complex images. Refer to the nodes for performing array-to-image transformations with color images.

connector_pane_image
datatype_icon

image in

Reference to the source image.

datatype_icon

U8 pixel values

2D array of unsigned 8-bit integers containing the pixel values that comprise the image.

The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The node resizes image to be the same size as image pixels. Use this input only when image is an unsigned 8-bit image.

datatype_icon

U16 pixel values

2D array of integers containing the pixel values that comprise the image used only for an unsigned 16-bit image.

The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The node resizes image to be the same size as image pixels.

datatype_icon

I16 pixel values

2D array of signed 16-bit integers containing the pixel values that comprise the image.

The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The node resizes image to be the same size as image pixels. Use this input only when image is a signed 16-bit image.

datatype_icon

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

datatype_icon

SGL pixel values

2D array of 32-bit floating-point values containing the pixel values that comprise the image.

The first index corresponds to the vertical axis and the second index corresponds to the horizontal axis. The node resizes image to be the same size as image pixels. Use this input only when image is a 32-bit floating-point image.

datatype_icon

image out

Reference to the destination image.

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.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
