Document Saving

How can I save selected images instead of all images to my server or database?

The API SelectedImagesIndices returns the indices of the selected images.

You can pass those indices as a parameter to HTTPUpload which uploads files to the server/database.

To upload all images in the buffer with HTTPUpload, you can use the API SelectAllImages which returns the indices of all images.

There are other HTTP upload APIs that can achieve the same. Please refer to this link: Dynamic Web TWAIN API Reference - IO APIs
