Sorry, 2 mistakes:
1-cmsDoTrasform is a Sub, so last Long is to be avoided
2-obviously, the For loop must be completed with a Next
Public Declare Sub cmsDoTransform Lib "lcms.dll" _
(ByVal hTransform As Long, _
ByVal InputBufferPtr As Long, _
ByVal OutputBufferPtr As Long, _
ByVal BufferSize As Long)
BufferSize is the number of pixels.
As Marti wrote in tutorial, windows aligne scanline on
double word boundary, so pay attention.
To transform an image:
Dim row as long,buf() as byte,bufptr as long
redim buf(wbytesperscanline-1)
bufptr=varptr(buf(0))
for row=0 to Imageheight-1
GetImageScanLine ' Imagerow ==> buf()
cmsDoTransform hTransform,
Byval bufPtr, _
Byval bufPtr, _
ImageWidth
PutImageScanLine ' buf() ==> Imagerow
next
