Screen Dump Query

:HCOPy:SDUMp:DATA? [GIF]BMPWMF

The query returns the current screen image as a file. If the optional file type is not specified it returns GIF type graphic data. The orientation is always portrait and the image is always in color.

The data is formatted as block data where the block of data starts with an ASCII header that indicates how many additional binary data bytes are following in the block. (e.g. #DNNN<binary data>) The binary data is the actual graphics file. To process the block of data you would:

•Read the first header byte #. The # tells you to read the next digit

(D). That digit tells you how many additional digits there are in the header. (In the above example D=3.)

•Then read the next D (that is, 3) bytes. The digits NNN tell you the number of bytes of data there are following the header.

•Those final data bytes are the screen image in the requested format. They can be saved as a separate file with a .gif, .bmp or .wmf suffix to use in other applications.
