NAME

dumpaed − dump aed display memory as a binary file

SYNOPSIS

dumpaed

DESCRIPTION

Dumpaed copies the contents of the aed display memory to the standard output for redirection to a binary file or for processing as a bitmap image. 

The output consists of a two-integer header (horizontal image size in pixels; vertical image size in pixels) followed by the image itself in left-to-right, top-to-bottom order, (horizontal_pixels / 8) bytes per scanline. For the aed, the horizontal size is 1024; the vertical size is 800. 

Dumpaed uses the whim.aed microcode and subroutine calls from the aed subroutine library to do its work. If whim.aed is not loaded when dumpaed is invoked, /dev/aed will be opened and whim.aed loaded, resulting in a glass tty microcode reload when dumpaed completes. (See ibmaed(4)). 

Dumpaed is provided primarily for use by bitprt(1).

NOTES

Dumpaed applies only to the IBM Academic Information Systems experimental display.

BUGS

Reloading of the glass tty microcode causes the aed screen to be cleared.
