More Sample Code please

[cutterman-cn]

I want to transfer images from Scanner and output to local disk.
when call source.waitReady(); the scanner start working and scan papers
But I dont know how to get the result images data from
source.imageNativeXfer(xfer);
this api only return one image result and I dont know how to get all.

Is there any codes like

for (int i=0; i<imageCount; i++) {
    // get image data one by one
   auto data = xfer[i].data();
  /// ....
}

or is there any simple way that I put a local path to some source api, where the source output image to that path automaticly.

thanks for help!

Hi @cutterman-cn,

twpp is quite close to the standard, low-level TWAIN API but with some added abstractions for convenience. You still need to familiarize yourself with the TWAIN specification in order to use it. Look for Advanced Application Implementation > Transfer of Multiple Images in the specification PDF, and you should be able to do it.
