dump_window_imagedump_window_imagedump_window_imageDumpWindowImageDumpWindowImage (Operator)

Name

dump_window_imagedump_window_imagedump_window_imageDumpWindowImageDumpWindowImage — Write the window content in an image object.

Signature

Description

dump_window_imagedump_window_imagedump_window_imageDumpWindowImageDumpWindowImage writes the content of the graphics window (WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle) in an image (ImageImageImageImageimage). To transform gray values the current color table of the window is used, i.e., the values of set_lut_styleset_lut_styleset_lut_styleSetLutStyleSetLutStyle remain unconsidered.

Attention

Under UNIX, the graphics window must be completely visible on the root window, because otherwise the contents of the window cannot be read due to limitations in X Windows.

Parallelization

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: local (may only be called from the same thread in which the window, model, or tool instance was created).
• Processed without parallelization.

Parameters

Result

If the window is valid dump_window_imagedump_window_imagedump_window_imageDumpWindowImageDumpWindowImage returns 2 (H_MSG_TRUE). If necessary an exception is raised.
