“convert” is a versatile and powerful command-line tool provided by ImageMagick for converting and manipulating images. ImageMagick is a widely used software suite that allows users to create, edit, and convert images in various formats.
The “convert” command-line tool enables you to perform a wide range of image conversion tasks. It supports converting images between different formats, such as JPEG, PNG, GIF, TIFF, and many others. You can specify the input image file and the desired output format, and “convert” will handle the conversion process for you.
In addition to format conversion, “convert” provides numerous options and features for image manipulation and enhancement. You can resize or scale images, crop specific regions, rotate or flip them, apply various filters and effects, adjust color levels, and add annotations or text overlays. These capabilities make “convert” a powerful tool for image processing and editing.
The “convert” command accepts a variety of parameters and options to control the conversion process and the desired output. You can specify the output image quality, compression level, resolution, and color depth, among other settings. This level of control allows you to tailor the output image to meet your specific requirements.
Moreover, “convert” supports batch processing, allowing you to perform operations on multiple images in a single command. This is particularly useful when you need to process or convert a large number of images simultaneously.
“convert” is not limited to basic image conversions and manipulations. It can also handle more advanced operations, such as image composition and montage. You can combine multiple images into a single image, overlay one image onto another, or create image mosaics using a grid layout. These features provide flexibility and creativity in generating complex and visually appealing compositions.
“convert” is highly extensible and can be integrated into scripts and workflows to automate image processing tasks. It can be combined with other command-line tools or incorporated into larger software systems, allowing for seamless image processing pipelines.
convert Command Examples
1. Convert an image from JPG to PNG:
# convert image.jpg image.png
2. Scale an image 50% its original size:
# convert image.png -resize 50% image2.png
3. Scale an image keeping the original aspect ratio to a maximum dimension of 640×480:
# convert image.png -resize 640x480 image2.png
4. Horizontally append images:
# convert image1.png image2.png image3.png +append image123.png
5. Vertically append images:
# convert image1.png image2.png image3.png -append image123.png
6. Create a GIF from a series of images with 100ms delay between them:
# convert image1.png image2.png image3.png -delay 10 animation.gif
7. Create an image with nothing but a solid background:
# convert -size 800x600 "xc:#ff0000" image.png
8. Create a favicon from several images of different sizes:
# convert image1.png image2.png image3.png image.ico
