- RE: HGDEM.ZIP Hi-Res HGA graphics in assembler.
- FROM: Scott A. Armitage #72750,2237
-
- A while back I was looking for some info regarding graphics for the
- 720x348 resolution mono graphics mode for HGA & compatable adapters.
- I found very little information other than 1 procedure for setting the
- modes.
-
- The procedures for setting the HGA controllers mode in this source;
- _GMODE, _TMODE & SETMD; were not written by me. I can't remember
- if those are what I found on compu-serve or if they were given to me by
- a teacher I had several years ago.
- If anyone recoginzes them credit to the author will be promptly given.
-
-
-
- Hgdem.zip contains the source code and executable program for a
- Hi-res graphics demo for HGA and compatible display adapters.
-
- The program draws variations of the graphics screens until a
- key is pressed.
-
-
-
- NOTE - INCLUDE file HGD.INC contains PLOT_LINE and CIRCLE
- routines to plot straight lines and circles. These procedures are
- based on routines by Rollins - "8088 Macro Assembler Programming".
-
- Modified slightly so that they both call the plot proc pointed to
- by the global PLOT_SUB word var.
-
- To re-assemble you will need to provide your own PLOT_LINE and CIRCLE
- procedures that call the PLOT_SUB address to plot the dots.
-
-
-
-
- The SOURCE CODE provided is intended for the use of compu-serve
- members only. Reproduction and distribution of source code must
- be negotiated.
-
-
- You may use any of the procedures in your own COMPILED program per the
- following.
-
- HGDEMO licence agreement.
-
- Single copy users $ 5.00
- (independent/freelance programmers)
-
- Corporate/business users $ 10.00 1st copy.
- 2.00 each additional
- machine using
- code provided.
-
- Please keep yours and your clients/employers systems from being
- in violation of FEDERAL LAW by registering this program if you
- find it to be useful.
