I’m using this example code:Manipulate PDF Document|Aspose.PDF for Java, for making searchable pdf from not searchable pdf, but quality of image resulting from img saving is very poor compared to the original.
The problem is that consequently tesseract does not recognize the text very well.
Can you help me to improve img quality please?
The space taken by its images does not matter, because they are erased immediately after treatment.
The quality of the final searchable pdf is ok.

You can create a PDF from scratch, and then insert page and image elements. Document instance represents a PDF document and Add method of the PageCollection class allows to insert an empty page. Please refer to this help topic: Add Image to Existing PDF File
