Important considerations
- You can get more than one result type from a single request. Use combined formats, such as
TextAndPdf,TextAndHocr,PdfAndHocr, orTextAndPdfAndHocr. - When the recognition result is returned as PDF, the resulting PDF document will contain the preprocessed image in the background and an invisible text layer on top of it. This text layer can be searched, indexed, selected, and copied.
- Almost all results (including plain text) are returned as Base64 encoded strings. You must decode them to display on the screen or save to a file.
