Write Image File (Write Image File (JPEG)) (G Dataflow)

Last Modified: March 26, 2019

Writes an image to a file in JPEG format.

JPEG format is not recommended if you want to make precise gauging or inspection measurements on the image.

connector_pane_image
datatype_icon

image in

Reference to the image structure to write as an image file.

datatype_icon

file path

Path name, including drive, directory, and file name, of the file to write.

datatype_icon

image quality

Amount of compression applied to the image.

image quality can range from 0 to 1000. The higher the value, the less compression the node applies. JPEG compression is lossy, which means that the lower the quality specified, the more loss takes place during the compression. Also, a small amount of loss can occur even when the quality is 1000.

Default: 750

datatype_icon

color palette

Unused input. The JPEG file format does not support color palettes. The input exists to address backward-compatibility issues.

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

image out

Reference to image in.

This node does not modify the image connected to the image in input.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
