BitMap Shape capture system







BitMap Shape capture system

*********************************************************
                 January 18, 2006

This set of programs allows you to: 
1)convert BMP's to hgr images
2)capture the shapes off the hgr screen
3)make a preshift table suitable for display by the
graphically speaking display code
4)view the preshifted animations

I use microsoft PAINT to edit the images.  You can use
an apple II paint program if you wish.



table driven HGR access is easy:

make the table:

make the graphics:

draw the shapes on screen:

SCRN function for HGR screen:
http://rich12345.tripod.com/prog/hirescrn.html 

allows you to capture graphics off the Hires Screen for
use with included HIGH speed graphics driver...  The
graphics to HGR code came from Graphically Speaking book.
This method of animation is called "animation of preshifted
shapes"... See the book Graphically Speaking, Chapter 12, 
Animation of Preshifted Shapes.
the book is available on CD at:

now (a softdisk publication) 
all memory copies are done with assembly 
a shape preview is shown on screen as well 
(all in assembly) 
runs just fine on a real unaccelerated II
