BSAVE using 16x16 graphics and VARSEG tiles(0) for example

[John Monti/]

So how should I place:

DEF SEG = VARSEG(tiles(0))
BSAVE "yourfile.ext", VARPTR(tiles(0)), 13800



First I would BLOAD like I did (this is just for example)

Once I do that and have them PUT on the screen, would I then need to get the ones that I want and then use BSAVE?

Better yet, let's say I wanted to BSAVE what I BLOADed.

I want to BSAVE them into a different file besides c:\paga\paga1.012

Let's say c:\qbasic\paga1.018

From code I've given, can you show how I would place the code you showed me for BSAVEing into it and eliminate what I don't need?

I already showed you everything you need to know. If you know how to use GET, you can replace the tiles with whatever you want. You put the BSAVE code at the end of your program.

Ok, thanks for the help; I appreciate it. Hope you got the PCX files I sent you as attachments in your E-mail. Do let me know if you receive them.

Screen 7 provides 8 pages on VGAs and 256k EGAs, 4 pages on 128k EGAs, or 2 pages on 64k EGAs.

Plasma, if screen 7 can provide as many as 8 pageson certain cards, why couldnt they make a mode 320x200 have up to 32 bit colour on certain cards!? (if my maths are correct)

[Plasma]

There is. VESA mode 10Fh.

If you're asking why didn't they do it on the VGA, it's because the technology didn't exist then.

[KiZ]

Ok, then could they not have provided extra video page support for screen 13, then? (VGA) Or did the technology not stretch that far either?

[Plasma]

There is. ModeX. 320x200, 256 colors, 4 pages.

Screen 13 only has 1 page because it's a chained mode. It's much easier to program for because you don't have to worry about switching planes. The tradeoff is you only get one page.

:o

I have heard of Mode X, how do you use it? Or is it only available by using asm?

[Plasma]

You set 13h and then unchain it. You can also tweak the resolution if you want, to get modes like 320x240 with 3 pages or 360x480 with 1 page.

Here's a pretty good explanation: http://www.brackeen.com/home/vga/unchain.html

It's in C, but it's easy to translate to QB. SJ Zero has some QB-only ModeX stuff, but it's only 320x240 IIRC.

Cool, im gonna try out Mode X if I can. Thanks for the link =)
