Making PSP eBooks with Linux
One of the drawbacks of the current PSP system software is the lack of a PDF viewer. However, using freely available tools you can easily turn your existing PDFs into high quality PNG images.
Requirements: GhostScript 7.x
First create a directory for the images you are transfering to the PSP. I generally use the title of the book or the initials:
mkdir ToH-PSP
Then use the GhostScript to turn each page of the PDF into an image:
gs -dSAFER -DBATCH -dNOPAUSE -r90 -sDEVICE=png16m -dGraphicsAlphaBits=4 -dTextAlphaBits=4 -sOutputFile=ToH-PSP/ToH.%03d.png -c save pop -f Tomb\ of\ Horrors.pdf
The “-r90″ specifies the output “resolution”. Change this to “-r150″ if you have highly detailed images in your PDF that don’t look good at 90.
The “-sOutputFile=ToH-PSP/ToH.%03d.png” tells GhostScript to write each image to “ToH-PSP/ToH.###.png” where ### are the numbers from 000-999. This will keep the pages in order when viewing on the PSP. Change this as appropriate.
Once you have created your images, simply copy the directory to the PSP’s “PHOTO” folder and enjoy!
