ImageFX(tm) GROB Saver Module
Written by Greg Simon
WHAT IS IT?
'GROB File' is a saver module for GVP's ImageFX Image Processing package.
It allows you to save an image in Hewlett Packard's GROB (GRaphical OBject)
format, suitable to be downloaded into any of Hewlett Packard's HP48-series
calculators. If you don't own an HP48(s,sx,g,gx) this program won't do
anything useful for you.
WHAT IT DOES
The saver module is very simple, it looks at the colors of each pixel
element (red, green, and blue), and if they are all < 125, a pixel is
created (remember, the HP48 has an on/off LCD screen). Thus, if you load
your favorite 256-color .gif image and save it as a GROB, it will appear
very strange and dull on your HP48 screen.
The GROB saver module writes the GROB image out (in ASCII), and also writes
some code around the image to view it. Thus, you can simply save the
image, and go DIRECTLY to your terminal program and download the saved file
to the HP48 for viewing.
The HP48's screen size is 131 x 64 (yes, 131 pixels across), however this
is not a limit for the GROB saver program.
