quality is the JPEG image quality (0–100). The default is the image quality that the server specifies. | ||||||

error in describes error conditions that occur before this VI or function runs.
The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code.
Use exception control to treat what is normally an error as no error or to treat a warning as an error.
Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

entire panel determines whether the VI captures an image of the entire front panel or only the portion of the front panel that appears in the window. The default is FALSE, which returns the visible area of the front panel. | ||||||
![]() |
content header contains a header line describing the content type of the image. Wire this output to the header input of the CGI Write Reply VI. | ||||||

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
