In image-only PDF files, many group 3 tiff images will be from faxes which can have resolutions such as 204dpi x 98dpi
Before using PDFXCp_SaveImageFromPage we need to be able to correctly determine the image object size from the PDF file, in order to be able to correctly set xDPI and yDPI - setting to some default such as 200 x 200 will result in an incorrectly scaled image.
Not possible as of today - but this weekend we will be releasing the Version 3.5 update which has a function (XCPage) to retrieve an object from a page and determine its properties and if neceesary during extraction to modify its properties and parameters - thus allowing you to achieve the desired results.
you can preview the help file from this link for the new v3.5 :
We are now moving our app to 3.5 so we need to be able to use the XCPage(?) method that was mentioned above to determine the X and Y resolution of the image so that we can save it correctly. Can you provide any pointers on how to do this?
