Thumbnail Preview Images

I have a quick question regarding thumbnail images.

FastPdfKit extracts thumbnail preview images automatically when the document is loaded in the view controller. Is it possible to specify the size of these images so that we can get better quality images.

I know we can use the API to get images of different quality but I was wondering if we can specify any option so that code that does this extraction at the time of document loading can do it for us.

Please advise.

    You should be able to change thumbnail size with MFDocumentViewController's thumbnailSize property. It is available since the last few releases.

    Let me know if this is of any help.

    I have the same problem. I looked inside the MFDocumentViewController but i did find the thumbnailSize property. Using thumbnailHeight thumbnail is big but grained. Is it possible to improve the resolution?
