Make PDF Book is a JScript program that converts all of the JPEG images in the folder of the script into a single PDF document using ImageMagick. This script requires that ImageMagick be installed and able to be accessed as an object.

// This script uses Imagemagick to convert all the files in the input into a single PDF document based on the alphabetical order of the input files.
// Options:
//     sInput          - The input file skeleton, for example "*.jpg" or "Test*.png"
//     sOutput         - The file name of the final PDF.
//     iDPI            - The DPI of the PDF page. 72 is the standard size for digital display.
//     iQualityPercent - What JPEG quality percentage the images should be set to. If -1, they will retain their current setting.
//     lForceSize      - If true, all pages in the PDF will have a width and height matching iPageWidth and iPageHeight. Images larger than the specified dimensions will be cropped, smaller will get a white matte.
//     iPageWidth      - The width of all of the pages in the PDF. Only used if lForceSize is set to true.
//     iPageHeight     - The height of all of the pages in the PDF. Only used if lForceSize is set to true.
