I have a serious technical complaint about the PDF which is available to all subscribers concerning Vol 4 of the Dead Suns AP. I have not checked yet as to whether the same problem is present in Vol 5. The problem is not present in Vols 1, 2 and 3 of the Dead Suns AP.
In previous PDFs published by Paizo -- virtually every single one of them going back to the very first PDF released for Pathfinder, the PDF security is set so that an end user can still use a software tool to extract the images from the PDF file.
In Vol 4 of Dead Suns, I can no longer do this with your PDF file. You have changed some setting within InDesign to prevent me from doing this. I expect this is unintentional -- but unintentional or not, the problem for your end users is significant.
I use the PDFs to create my adventures for use by my players on a VTT. I need to be able to access both the maps and character art within the PDFs to be able to do this. I can't access the character art in this volume and the Character art JPG and PNG image mask is not extractable.
Please appreciate that I subscribe to the Starfinder AP line so that I will have the PDF for the adventure from Paizo available to me to assist me in running my games via VTT. That is the principle reason why I do so. By locking the character images from being accessed and extracted in this fashion, a significant element of the reason I subscribe in the first place has been removed from the product. That's a MAJOR problem for your subscribers as it impacts on its value-in-use when using the product to play Starfinder.
