PB and Graphics Files..

[Tyrone W. Lee]

Some users on PB has suggested I convert my game application to 100%
PowerBasic. I have a series of questions about PB and graphics in general.

1. If I were writing the game for PB/DOS .EXE how would I set graphics
mode in PB?

2. If I remain under windows. How could I load graphics file. (.BMP, .GIF, .JPG)
Are there any PB routines already available to handle this?

under windows you can load bmp's with loadimage.
from win98 and nt 5.0 you should also be able to load jpeg's.
gif's are more problematic! (see my post: http://www.powerbasic.com/support/pb...ead.php?t=3704)

Regarding your PB/DOS comment... you would use the usual PB/DOS SCREEN statement, which supports up to screen 12.

There are libraries in the DOWNLOADS section for Mode-X and Vesa graphics modes too.

However, this is really off-topic for this forum... posting PB/DOS enquiries in the PB/DOS forum will probably net you a greater response from *active* DOS programmers!

Without knowing your experience with Windows graphics programming, I have to point out that there are tremendous differences between graphics programming in Windows and DOS... a good Windows programming book can be worth it's weight in gold, especially if you want to go the API route for Windows graphics programming.

Go to http://www.openil.org

and get http://download.sourceforge.net/open...ler-2.1.4b.exe

It's a free OpenSource image library that handles a lot of formats.
It comes with PB headers and samples.
You are free to use it for commercial applications too (Licence LGPL)

If you only need to display bitmap images, you could use a static control created with the bitmap style, e.g.

hWnd = CreateWindow( "STATIC", $NUL, %WS_CHILD OR %WS_VISIBLE OR %SS_BITMAP, nX, nY, _
nWidth, nHeight, hWndParent, nID, hInstance, %NULL )

You may need to add other styles as required. You then load the image from a resource or file using LoadBitmap() or LoadImage() and tell the static control to display it by sending it a STM_SETIMAGE message.

Using GIF images is somewhat more complicated. The issues involved are explained in MS KB article #Q193543.
