Crop To Margins
Script for Adobe Photoshop
Latest update 9/28/2022, version 2.1
Crop images to result in margins a percentage of the subject size.
- Crop current image or folder of images
- Option to use content-aware fill
- Append suffix to output file names
- Output to JPG, PNG, PSD, or TIF
- Save and restore all settings
IMPORTANT: the script depends on the Photoshop feature Select Subject that was introduced in Photoshop CC 2018 (version 19). Earlier versions of Photoshop will not run this script correctly. For best results use the latest version of Photoshop as the Select Subject feature has improved greatly in recent years.
How to use the script
The interface has four sections: Process, Margins, Output, and Settings. Set options as desired and click OK to begin. If processing the active image, any errors or concerns are reported immediately. If processing a folder, a progress bar is displayed. To cancel processing, press the ESC key. Otherwise, when complete, the number of images processed is reported. If any concerns are encountered, a log file is written to the output folder, and the user is notified.
The script depends on the accuracy of Photoshop’s Select Subject feature, which works well in most cases, but isn’t perfect 100% of the time. At a minimum, the user should open Bridge and scan through thumbnails of cropped images to ensure the results are satisfactory. For any images that crop improperly, open in Photoshop and crop manually.
Section 1: Process
Active image — processes the image that is currently open and the top-most window if multiple images are open. When this option is selected, the section Output is disabled. It is for the user to perform additional transformations if needed and Save As the cropped version of the image in the desired format. A revised file name should be used to preserve the original un-cropped version of the image.
Folder — Processes a folder of images. Click the button Folder to select the desired input folder. If the option Include subfolders is checked, all folders in the selected folder are also processed, with the exception of the folder selected in the Output section, if it is below the input folder. When the option Include subfolders is enabled, the subfolder structure is created in the output folder. If Photoshop cannot open an image or other problems occur, alerts are reported in the log file. For each image file found, the script crops the image to have the specified margins.
Section 2: Margins
Percentage of subject dimensions — margins are based on one of the subject dimensions. Choose either long or short dimension.
Margin and Percent, Left, Top, Right, and Bottom — enter a percentage of subject dimension (set above) to specify the margin each side of the image. Click the checkbox Center to make all margins an equal value.
When image is less than crop — when the cropping boundary exceeds the original image, the user may choose to fill the missing area with the current background color, use content-aware fill to complete the missing image, or adjust the cropping boundary so that it does not exceed the original image. In any case, the condition is reported in the log file, or reported immediately if cropping the active image.
Section 3: Output
Folder — the location to which cropped images are saved. Click the button Folder and navigate to the desired location.
Format — choose from four common file formats: JPG, PNG, PSD, or TIF.
Flatten — reduces layers to a single background layer. If disabled, layers remain, but understand that some formats and situations always flatten the image. For example, output to JPG, because the format does not support layers. The PNG format is always converted to sRGB web standard, and this can also trigger flattening. As well, images converted from RGB to CMYK may flatten to preserve the effect of adjustment layers, which cannot convert from one color space to another.
Quality (JPG format only) — valid range is from 0 to 12. 0 is extreme compression resulting in low quality. 12 is light compression that is virtually indistinguishable from the original, the highest possible quality, which of course, results in the largest file size. 10 to 12 is recommended for print or other high-quality reproduction. For web images, 5 to 8 is an acceptable range.
Convert to profile — the cropped image is converted to the specified profile. Note that PNG always converts to sRGB web standard. All other formats embed either the original color profile or the profile to which the image is converted.
Original file name + — a suffix of characters appended to each cropped image file name. The characters entered must be legal to use in file names. Having no suffix is allowed, but note that without a suffix, output to the input folder is not allowed to prevent overwriting input files.
When cropped images are output, any existing cropped images of the same name are replaced without alert.
Section 4: Settings
The current options may be saved and restored later. Select from the Load drop-down list to choose saved settings, and the current options are updated. Click the Delete button, and the saved settings selected in the Load drop-down list are permanently removed. Click the Save button, provide a name for the settings, and the current options are preserved. If the name already exists, the user may choose to replace the saved settings. Or click the checkbox Replace settings, and choose the settings to replace.
The script provides default saved settings named [Default]. These settings cannot be deleted but may be updated to the current values. Save settings, click the checkbox Replace settings, and choose [Default].
Available color profiles
For the option Convert to profile, the list of profiles from which to choose is compiled by searching known locations in the system for .icc/.icm files and extracting the profile name. This occurs each time the script is launched. The list should include most of the same profiles Photoshop displays in dialogs such as Color Settings, but it doesn’t match exactly. If a needed profile does not appear in the list, add the profile to a location both Photoshop and the script look for profiles (below), and relaunch the script.
