Yes, I think you and I looked at this a few months back, I think you had worked out something with Matrixes.

>>Hi Mike,

>>Thanks for the sample. I've seen some code very similar to this that "dims" the controls on a form. What I'm looking for, I suppose, is the opposite effect where the colors get "brighter". I'm clueless about the GDI library, its classes and RGB color values.

>>>Yes you can. This example is not exactly what you want, but it can get you started. The following change a colored JPEG image to a grayscale image. The function is too slow to be used as is, but you will get the idea.
>>>

cImage = Getpict('jpg')
>>>ConvertToGrayscale(cImage)
>>>
>>>Function ConvertToGrayscale(lcImage)
>>>Set Classlib To Home()+'ffc/_gdiplus.vcx' Additive
>>>oLogoImage = Newobject('gpBitmap',Home()+'ffc/_gdiplus.vcx')
>>>oLogoImage.CreateFromFile(lcImage)
>>>Private x,Y,nColor
>>>lnWidth = oLogoImage.imagewidth
>>>lnHeight = oLogoImage.imageheight
>>>For Y=0 To lnHeight-1
>>>	For x=0 To lnWidth-1
>>>		Wait Window Nowait "Width in pixels: "+Transform(x)+", height pixels :" +Transform(Y)
>>>		nColor = oLogoImage.GetPixel(x,Y)
>>>		oColor = Createobject("gpColor",nColor)
>>>		oAvg = (oColor.Red+oColor.Green+oColor.Blue)/3
>>>		oColor.Set(Int(oAvg),Int(oAvg),Int(oAvg))
>>>		oLogoImage.SetPixel(x,Y,oColor.ARGB)
>>>	Next
>>>Next
>>>oLogoImage.SaveToFile("c:\ex.jpg","image/jpeg", "quality=100" )
>>>Endfunc
