Description
The normalized max error per pixel computed when an image is color reduced.Examples
Compares two images:
Set Variable [$img1; Value:MBS( "GMImage.NewFromContainer"; test::Container1 )]
Set Variable [$img2; Value:MBS( "GMImage.NewFromContainer"; test::Container2 )]
Set Variable [$result; Value:MBS( "GMImage.Compare"; $img1; $img2 )]
If [$result = 1]
Show Custom Dialog ["Image Comparison"; "equal"]
Else If [$result = 0]
Set Variable [$e; Value:MBS( "GMImage.NormalizedMaxError"; $img1 )]
If [$e ≠ 0 and $e < ,03]
Show Custom Dialog ["Image Comparison"; "very similar: " & MBS( "GMImage.NormalizedMaxError"; $img1 )]
Else
Show Custom Dialog ["Image Comparison"; "not equal"]
End If
End If
Set Variable [$r; Value:MBS("GMImage.Release"; $img1)]
Set Variable [$r; Value:MBS("GMImage.Release"; $img2)]
