Using Photoshop to slice a raster image of text questions into individual images


Does anybody know of a place I could look into information about a script that could slice a flat, rasterized image into individual images for each block of text? I have hundreds of pages.


I am working on a single columns where there is a complete row of horizontal whitespace between each question. My ideas were to find the rows of whitespace or to find the pattern of the number before the question. (like (1), (2),...(50), etc) and translate off of that. Attaching example image.

Answer



There's one script that I know of: Split to Layers.


To make it work with this script, there 3 major steps to the process:




  1. Remove the background

    • This "Split to Layers" script requires the background to be transparent, so you need to remove the background first.

    • I was relatively careful with the background removal, but the script only sees transparency as empty space, not white or any solid color. So if that isn't a factor for you, you can sort of ballpark the background removal without risking deleting any pixels from the text.



  2. Run the "Split to Layers" script.

  3. Export layers to files File > Export layers to files...


    • If you have an older version, you may find it in: File > Scripts > Export layers to files... (or was it File > Automation > ...).




Left side is the script preview showing how it's about to split it. Right side is a gif sort of showing how each layer ended up split.

You can also copy the script here (Save as "Split to Layers.jsx"):

//Change any of the following 5 values to customize the default options for the script:

var showOptionsDialog = true; //Set to false to disable prompt to user.
var tolerance = 0;            // the largest gap of transparent pixels that will be ignored. Also sets default
var confirmThreshold = 20;    // If the script is going to make a large number of layers, prompt user to confirm that this is OK
