Hi,

In order to conserve memory, I wish to use about 1/4 (250 X 200pels ) of the vga screen for a hi-res map·, ·with the rest of the display reserved for text using the rom characters. Presently I am using the 512X384 demo object which displays TEXT and VGA. How can I achieve this ? I guess that I would have to get into the nitty gritty of the object ?

·Thanks

Chris

You can use "Graphics" to cover just a portion of the screen. Eliminate the double buffering to conserve space...

Here's a link to a 1024x768 demo that uses this (see first link on this page):

Also, if you look at the bottom of this page:
http://www.rayslogic.com/propeller/Programming/RaysStuff/RaysStuff.htm

there are some changes I made to that file to move and resize the graphics windows...
