Hi
Where I can find a sample of converting a PDF to images and then OCRing the images?
Please check following articles in API documentation in order to convert PDF Pages into Images (using Aspose.PDF) and Perform OCR on an Image (using Aspose.OCR):
What is the recommended output for OCR ? PNG?
So I have to convert PDF to images, then OCR the images, cleanup the images…
You may please check all supported formats for the API. However, the image quality and resolution should be good enough to process it e.g. 300DPI.
