I need some help with capabilities. I have done some capabilities testing in two different scanner with twack twain tool: Scanner A: see scannerA.jpg Scanner B: see scannerB.jpg I don't understand the scanner B capabilities for XResolution....what are this values: 78.667,94.400,118.000,157.333??? If you see the scannerB.jpg image, I can't get the max value, min value, step value... Then, As I have developed my application using scannerA, when I query the ImageXResolution.RangeCapability.MaximumValue or the ImageXResolution.RangeCapability.StepSize in scannerB I get an error... Could you give me some advice please?? I'm sorry about my poor english, I hope you could understand my problem. Thanks very much, Pablo L.G.    Report

This means if you can use MSG_SET to specify a value in it, you should also be able to use LEADTOOLS SetCapability function. If there's a problem in the driver working with Twacker in any way, it will also fail to work with our toolkit. About the capability value returned by the Twain driver, you can only check for minimum and maximum if the ContainerType was TwainContainerType.Range. For other types you cannot get Min and Max values. Adam Boulad LEADTOOLS Technical Support    Report
