cutjpg

cutjpg is a command-line utility designed for image manipulation, specifically for cropping JPEG images. It allows users to extract a rectangular portion of a JPEG file by specifying the desired coordinates and dimensions. The tool is typically used in scripting and batch processing scenarios where automated image editing is required.

The primary function of cutjpg is to define a bounding box within an existing image. This is usually achieved by providing parameters such as the top-left corner's x and y coordinates, and the width and height of the desired cropped area. The output is a new JPEG file containing only the specified region.

cutjpg is known for its simplicity and efficiency, particularly when dealing with large numbers of images. It avoids the need for graphical user interfaces, making it suitable for server environments or automated workflows. Installation and usage generally involve downloading the executable and running it from a terminal or command prompt. While its name suggests it only handles JPEG files, some versions or similar utilities might support other image formats. Its purpose is fundamentally to segment images based on user-defined rectangular regions.
