montage:tldr:25a99
The command you provided is a Unix/Linux command used to create a visual montage of multiple images.
Here is the explanation of the command, broken down into segments:
-
montage: This is the command to create a montage. It's part of the ImageMagick software suite which is commonly used for image manipulation tasks. -
${image1-png}: This represents the first image file name or path, which is in PNG format. The${image1-png}part is a placeholder, indicating that you need to replace it with the actual file name or path. -
${image2-jpg}: This represents the second image file name or path, which is in JPG format. Similar to the previous one,${image2-jpg}should be replaced with the actual file name or path. -
${imageN-png}: This represents the Nth image file name or path, again in PNG format. The${imageN-png}part should be replaced with the actual file name or path of the Nth image. -
-geometry 640x480+0+0: This specifies the geometry of the montage, meaning the size and position of each image within the final montage. In this case, it sets the size of each image to be 640 pixels wide and 480 pixels tall, and places them at coordinates (0,0). -
montage.jpg: This is the output file name for the montage. The resulting visual combination of all the images will be saved as a new image file named "montage.jpg".
Therefore, when you replace ${image1-png}, ${image2-jpg}, and ${imageN-png} with the actual image file names or paths, and execute the command, it will combine all the specified images into a montage, with a size of 640x480 pixels, positioned starting from the top-left corner, and save it as "montage.jpg".
