Contrast function converts color image to bw image

Hi

I tried to change the contrast of the bitmap using

Sub Button_contrastplus_Click
   bitmap2=ii.Contrast(bitmap2,10)
   imageview1.bitmap = bitmap2
End Sub
Sub Button_contrastminus_Click
   bitmap2=ii.Contrast(bitmap2,-10)
   imageview1.bitmap = bitmap2
End Sub

but instead of changing contrast the whole bitmap changed to Grayscale image

any solutions?

Thanks in advance

have you tried lesser values?

bitmap2=ii.Contrast(bitmap2, .10 )

bitmap2=ii.Contrast(bitmap2, 2 )

 

[mkvidyashankar]

Yeah I tried lower values. But same thing repeats

 

[vb1992]

you can test out this library

I believe it also has brightness/contrast
to see if it works
