vsTwain1.OpenDataSource();
vsTwain1.UnitOfMeasure = UnitOfMeasure.Inches;
vsTwain1.Brightness = vsTwain1.BrightnessMaxValue;
vsTwain1.SetImageLayout(1, 1, 6, 4);

I am trying to scan a card that is 6 inches and 4 inches wide and am getting an error in setting the image. What am I doing wrong?

Bill

I too am getting the same error I presume the scanner does have capability to be able to do this since the error does not say "Capability is not supported." (as it does for set pagesize) - Here is the code at which it errors and the last few lines of my log file:

VsTwain1.SetImageLayout(0, 0, 3, 4)

many thanks

Yes I am sure it is in inches, i set them to inches and then Got layout to see what the current size was during debug.

VsTwain1.UnitOfMeasure = UnitOfMeasure.Inches
Dim lay As String = VsTwain1.GetImageLayout()
VsTwain1.SetImageLayout(0, 0, 3, 4)

Can you link where i ought to download the new version? I have bought the version 5.0.3.3 , and i can only see a download for the evaluation dll.

However I will still send you the 5.0.3.3 log file.

many thanks

I have the same problem. Error when setting image layout.

here is my code:
VSTwain1.OpenDataSource()
VSTwain1.Resolution = 150
VSTwain1.PdfImageCompression = PdfImageCompression.Auto
VSTwain1.PixelType = PixelType.GRAY
VSTwain1.UnitOfMeasure = UnitOfMeasure.Inches
VSTwain1.SetImageLayout(0, 0, 8.5, 11)
VSTwain1.Acquire()

here is the twain log
