Image from a buffer

ok, you don't have to use a dll to do this, i would only use a dll if i really had to personally.... but onto the task. ok, this is from something i just wrote a few days ago actually, i got the information from the read/writepixelfast examples i think, the docs can cover this stuff if you can pay attention for long enough that is! heh

this is how to load a bmp and read the pixels into a pixel array for writing to later, comments below.

xdim=256 : ydim=256 ;the image dimension vars
Dim Imagedata(xdim,ydim) ;size pixel array
mypic=LoadImage(filename$) ;load a bmp

DrawImage mypic,0,0 ;draw image to screen
LockBuffer ;must have for ReadPixelFast
 For y=0 To ydim ;x/y loop
  For x=0 To xdim
   Imagedata(x,y)=ReadPixelFast(x,y) ;read to array
  Next
 Next
UnlockBuffer
Cls ;clear image from screen

now you've got all pixels in the array, you want to, ehh...
create the image from the data now. ok, this writes the pixel array to a new image.

 mynewpic=CreateImage(xdim,ydim) ;size new image
 SetBuffer ImageBuffer(mynewpic) ;put image in buffer

LockBuffer ;must have for WritePixelFast
 For y=0 To ydim ;draw new image
  For x=0 To xdim
   WritePixelFast x,y,Imagedata(x,y) ;write to image
  Next
 Next
UnlockBuffer

 SetBuffer BackBuffer() ;reset to screen buffer

I cant garantee this code is 100% perfect, as i havent tested, but it should be. One thing id like to mention is that i found writepixelfast doesn't work in fullscreen 16bit!? but plot does, its a little slower and more complex but at least it works, i guess.

Hope that helps some anyway.
