GSKPDFImageProcessor

@protocol GSKPDFImageProcessor

Used to preprocess pages of the PDF generation.

When you generate a PDF document from images, you may want to apply some preprocessing to each image before inserting them in the document (for instance resizing them, including a watermark, etc.) You can implement your own PDF_image_processor and pass it when generating a PDF document. to achieve this.

  • Process the image and return a file path to the updated image. The PDF processor will delete this temporary image afterwards (only if it’s different from inputFilePath )
