How to use

1. Drag and drop jpeg/tif images or a folder with images
2. BookCrop overlays them into one preview
3. Draw a rectangle and click "crop" to crop all images

Setup

• Install latest GraphicsMagick (Q8 version is faster)
• Get two files from libjpeg-turbo:
  • Download libjpeg-turbo-1.5.3-gcc64.exe or newer
  • Unzip the .exe with 7zip
  • browse to \bin subfolder
  • copy jpegtran.exe and libjpeg-62.dll and place next to BookCrop.exe

More Features

• Ctrl+Click and draw another rectangle to split crop into two images with L and R suffix.

• Ctrl+Tab starts R L mode. Files ending with L.jpg and R.jpg are previewed and cropped separately.

• R / L at preview: rotate preview in 90 degree steps.

• S at preview: Scrub mode. Draw a rectangle to whiten that area in binarized tif input images. Useful for scrubbing noise near inner/outer edges on book page photos.

• Command line input: a folder path or image filepaths or a .txt with one image filepath per line.

BookCrop.exe "C:\folder"

BookCrop.exe "C:\dir\a.jpg" "C:\dir\b.jpg"

BookCrop.exe "C:\files.txt"

• Drop a folder: Process all jpg or tif in folder (whichever there is more of).

• Drop a single jpg or tif: Quick preview. Move threshold slider to refresh.
  Change threshold in quick preview if the overlay is too dark or light.

• Important: Preview and cropping only works well on same size input images.

• Advice: Use crop to subfolder, so you can redo if you crop too much.

• If you wish to run/build BookCrop.ahk from source: install AutoHotkey

FAQ

Q Scrub mode does not work on certain .tif files, why?
A Scrub fails if the .tif has JPEG compression. Remove the compression manually from the images first.
