Pixels Per Inch

This Paint Shop Pro script for PSP X, 9 and 8 takes a folder and converts all 300ppi jpg's and png's in it to 200ppi.

This is very handy when you want to share or upload files with and to other scrappers or sites. 200ppi looks just as good and is much smaller in file size. And because you also get to keep the folder with the 300ppi files, you have your files ready for the printshop that insists on 300ppi.

The attached script is still in beta, just to be sure. The steps are:

200 pixels per inch Link: Resolution 


From Lori Davis: Yes, I wondered whether you meant half the file size rather than half the pixel dimensions. Folks here should realize that, as you indicate above, the PNGs will have file sizes even less than 1/2 that of the original 300ppi versions. For JPEGs, you can't really predict the file size of the new images, since that will depend in part on the compression factors for both the originals and the converted files.

Yes - it's changing the PPI to 200 and rescaling to maintain print size. And yes - there will be a BIG change in file size, as planned.

Hope everyone can test it out and give it a good shakedown. Jos and Joske have put a lot of time into this. Lori and I have given them some input but we really need some hard-core 300 ppi scrappers to give it a run!


From Trevor:

I did a test by opening PSP, then opening a jpg from a folder on my hard drive called My Documents\My Graphics

I then ran the script that had been placed in My Documents\My PSP Files\Scripts-Trusted

The file sizes are reflected in the following table:

Original jpg 300 File size Filesize at 200ppi
Backlit redo.jpg 1,079 1,252
House photo.jpg 344 133
100_223.jpg 1,170 1,157
After 5.jpg 137 80
After5_high_key.jpg 499 223
After5_scattered.jpg 1,715 750

Obviously, the percentage file size difference is not the same, but there is a saving, and I didn't notice reduced quality.

Notice that one must place the script in your My Documents\My PSP Files\Scripts-Trusted folder, and that one must start Paint Shop Pro, and then open a file that resides in a specific document folder. The script runs from PSP version 8 onwards.
