Is there source code for capturing screen in mode 640x480 (64K and 16M), then saving it in BSAVE mode? if yes, then how should I use DEF SEG and BLOAD for using the saved screen? I don't know segment and offset address that I should use.

How about converting the captured screen into sprite file format (QUICKBASIC format)?

Frankly, I do not really understand any programming language. I'd love to appreciate anyone who assist me.

Thank you very much.

There was one program I know that captured 640x480 into 4 parts and save these 4 parts as individual files. I think I have the code somewhere on my computer. Want me to look for it?

I think I have the code you are looking for. It saves the 640x480 - screen 12 into 3 RGB files (1 per plane) and other 1 for the intensity, using DEF SEG and BLoad, so it is very fast.

The code above opens a vesa screen 640x480x8. Then draws random colored pixels and then saves it to 'C:\QB:BMP'. The Usage with Screen 12 is much more easy. But, you must set the;
BMP.BPP
BMP.ImageSize
BMP.FileSize values with the desired numbers...

Screen 12 uses 4 bit color depth thus one byte in image data in a bmp file contains 2 pixels... So the sizes reduced as their half values... Hope This was helpfull...

well done Tolga. But what about BSAVE and BLOAD ?

The link I posted above works with BSAVE and BLOAD.

Hi guys. I've finally found the code. Here it is, simply copy and paste it to a new .BAS file. It runs (for me, at least) on Qb45 and PDS7.1

Ooops... seems I don't know how to use the "

:P

I fixed it. It was somewhat old code in the system. It looks like it's working now.

start a qbasic and write programming
