Can I import existing images or PDF documents using the Dynamic Web TWAIN SDK?
Yes, Dynamic Web TWAIN supports loading PNG, JPG, BMP, image-only PDF, and TIFF files. But if you need to support text-based PDF files, you also require the PDF Rasterizer Addon. See more here.
Code snippet
var onSuccess = function() {
console.log("Loaded a file successfully!");
};
var onFailure = function(errorCode, errorString) {
console.log(errorString);
};
DWObject.IfShowFileDialog = true;
// PDF Rasterizer Addon is used here to ensure text-based PDF support
DWObject.Addon.PDF.SetResolution(300);
DWObject.Addon.PDF.SetConvertMode(Dynamsoft.DWT.EnumDWT_ConvertMode.CM_RENDERALL);
DWObject.LoadImageEx("", Dynamsoft.DWT.EnumDWT_ImageType.IT_ALL, onSuccess, onFailure);
Yes
No
