Making Traveller Geomorphs Extractions for use on VTT

I describe here how I used some quickly built AI Java tools to extract images from a PDF book, capture sub images from each page, and add the ability to colorize them Traveller Geomorphs is a collection of spaceship, or space station deck plans useful for RPGs needing maps or miniatures.

PDF to image step:

  1. Download Geomorphs pdf from travellerrpgblog.blogspot.com
  2. Download my pdf-utils project from github.
  3. Compile and run PDFImgExtractor against the location where you are keeping your geomorphs PDF.
  4. It saves a series of images to a folder with the same name as the pdf file's prefix.


Colorize images step:

  1. Download my ImageColorApp
  2. Compile and run ImageColorApp against the image folder with the color that you want to convert the images to, ex. FF0000
  3. It creates a folder with that color name with the colorized images in it.
  4. Can use these images on VTT.
