The WRITE_PICT procedure writes an image and its color table vectors to a PICT (version 2) format image file. The PICT format is used by Apple Macintosh computers.
Note: WRITE_PICT only works with 8-bit displays
This routine is written in the IDL language. Its source code can be found in the file
write_pict.pro in the
lib subdirectory of the IDL distribution.
WRITE_PICT, Filename [, Image, R, G, B]
A scalar string containing the full pathname of the PICT file to write.
The byte array to be written to the PICT file. If Image is omitted, the entire current graphics window is read into an array and written to the PICT file.
The Red, Green, and Blue color vectors to be written to the PICT file. If R, G, B values are not provided, the last color table established using LOADCT is included. If no color table has been established, WRITE_PICT calls LOADCT to load the grayscale entry (table 0).
Create a pseudo screen dump from the current window. Note that this works only on a PseudoColor (8-bit) display:
