Hi,

    Is there any documentation on how to convert code based on LEADTOOLS 12 to LEADTOOLS 15? Right now I have specific trouble converting members of TWAINPROPERTIES TO LTWAINPROPERTIES, but more questions might come. What exactly to do you convert nRes and nBits? Do you convert nWidth and nHeight to margins? We still use Visual Studio 6 (yeah, yeah) and C++.

I
recommend that you use the L_TwainSetCapability function and call it repeatedly
to set the individual capabilities you need one by one. This will give you better control and fewer problems when dealing with different scanners.


For the
DPI, use the ICAP_XRESOLUTION and ICAP_YRESOLUTION capabilities. For the color resolution, use ICAP_PIXELTYPE.


For the
scan area, either use Image Frames (ICAP_FRAMES) or the Image Supported Sizes (ICAP_SUPPORTEDSIZES) capabilities, if they are supported by the Twain driver.
