ImageMagick is a powerful open-source command-line image processing tool that supports almost all common image formats. It can be used independently as a command-line tool or integrated into other programs as a library, and is widely used for batch image processing, format conversion, resizing, watermarking, compression optimization, image effects, and animation processing.
ImageMagick PC Version Introduction:
ImageMagick™ is a free software for creating, editing, and compositing images. It can read, convert, and write images in various formats. It supports image cropping, color replacement, application of various effects, image rotation and combination, text, lines, polygons, ellipses, curves, and appending to images for stretching and rotation. ImageMagick is free software: all source code is open, and it can be freely used, copied, modified, and distributed. It complies with the GPL license. It can run on most operating systems. Most of ImageMagick's functionality comes from the command-line tool. Generally, it supports the following programming languages: Perl, C, C++, Python, PHP, Ruby, and Java; readily available ImageMagick interfaces (PerlMagick, Magick++, PythonMagick, MagickWand for PHP, RubyMagick, and JMagick) are also available.
What is ImageMagick?
Full Name: ImageMagick
Type: Free and open source, cross-platform (Windows, Linux, macOS available)
Main Functions:
Batch image format conversion (e.g., JPG to PNG, WEBP to JPG, etc.)
Image scaling, cropping, rotation, flipping
Adding watermarks, adjusting brightness/contrast/saturation
Image compression, optimization
Creating animated GIFs (e.g., GIF compositing and decomposition)
Image merging, splitting, stitching, adding borders
Overlaying text or other images
Supports automated batch processing via scripts
What are its uses?
Website development/maintenance: For example, automatically generating thumbnails, batch compressing and optimizing images, batch adding watermarks, etc.
Designers/content creators: Quickly batch process images to improve work efficiency
Programmers: As a backend image processing engine, integrated into various applications, automated scripts, and data processing workflows
Daily batch processing: For example, using a single command to shrink, convert, and even automatically rename 1000 photos.
ImageMagick Features
Animate
Utilizing X Displaying Animated Images
**Display**
If you have an X server system, it can display images sequentially.
**Import**
Export image files to the X server or any visible window. You can capture a single window, the entire screen, or any rectangular portion of the screen.
**Compare**
Evaluate different images and their modifications arithmetically and visually.
**Montage**
Create separate feature images. Add arbitrary decorative elements to images containing feature images, such as borders, structures, image names, etc.
**Conjure**
Interprets and executes scripts written in MSL (Magick Scripting Language).
Creates thumbnails.
A large number of filters and extensions for special effects.
Frequently Asked Questions
How does the software change the width and height?
By default, width and height represent the maximum size of the image to be converted. `Convert` controls the width and height of the image to ensure proportional scaling.
For example: `convert -resize 600×600 src.jpg dst.jpg`
The converted image size of `dst.jpg` (width 600, height proportionally adjusted to 450).
II. How to improve the contrast of a PDF using software?
1. Use software to convert the PDF to an image;
`$ convert 1.pdf 1.jpg`
2. Use GIMP to determine the white and black thresholds;
3. Use software to modify the contrast;
`$ convert -level 38%,99% 1.pdf 2.pdf`
III. How does this software compare to other graphics processing libraries?
OpenCV primarily demonstrates its implementation in the form of algorithms; that is, it actually provides various image processing algorithms. For specific applications, these algorithms need to be combined to achieve a particular function.
GraphicsMagick is known as the Swiss Army knife of image processing. GraphicsMagick's concise code provides a robust and efficient collection of tools and libraries for handling image reading, writing, and manipulation.
ImageMagick primarily demonstrates its implementation through applications, such as image cropping, image fusion, image blurring, and image sharpening.
