I'm doing a bit of programming for someone to convert printshop images,
but I seem to have the exact details messed up a little.
I know (er, at least I think I do...) that PrintShop images are bit maps
of 88 * 52 stored in 11 (88/8) lots of 52 bytes, which represent the
image. This is strange but I make the pic size 572 bytes in size (52*11)
but the size of the binary files is infact 576 bytes.
My algorithm to convert these back to pixel images ( converting the 8 bit
bytes to 7-bit Hi-Res type pixel maps) seems to work well, but the images
are somewhat defective after I process them. I think this might have
something to do with those four extra bytes, or the lines not being quite
as simple as I first thought. (I have no qualms about being shown the
error of my ways)
If you know how the file represents the screen image (where those extra
bytes fit in) I would be pleased to hear from you. Email responses are
prefered, coz sometimes our news goes down (and I mean way down) here..
Also, I wonder if anyone knows whether or not its possible to contact
Roger Wagner Publishing over the internet, I would also be appreciative of
these secrets.
Many thanks in advance...
cheers
