Extracting images - a question and requests

Aspose.PDF Product Family
1

As I have mentioned in a previous post (Error & performance problems extracting images), I am interested in extracting the images from a pdf document, compressing the images, and then replacing the images in the pdf document. I would like to extract the images as they exist in the pdf document without alteration. I noticed the PdfExtractor.Resolution property which seems to imply that extracted images will be converted to the resolution specified by this property. Is it possible to avoid this and extract the images without altering the resolution?

The documents I am working on have a page header with a company logo. When using the ExtractImage and GetNextImage methods of PdfExtractor, the header image is repeated for each page. I am interested in optimizing performance and would like to skip over these repeated images. Can you add a SkipNextImage method, or provide a way of extracting an image specified by ImageDescription.Index?

Of course it would be much easier to process the images if the PdfContentEditor class (which has the ReplaceImage method) also supported an ExtractImage method using pageNumber and index as parameters.

Thank you,
Ken

Hi Ken,

Our team has looked into these requirements in detail and I would like to inform you that these new features will be supported after Q2’2011; I’m afraid, we’ll not be able to provide these features earlier.

We’re sorry for the inconvenience.
