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);
};
DWTObject.IfShowFileDialog = true;
// PDF Rasterizer Addon is used here to ensure text-based PDF support
DWTObject.Addon.PDF.SetReaderOptions({
convertMode: Dynamsoft.DWT.EnumDWT_ConvertMode.CM_RENDERALL,
renderOptions:{
renderAnnotations: true,
resolution: 300,
}
});
DWTObject.LoadImage();
