convert:tldr:397ab

This command is using the command-line tool "convert" from the ImageMagick software to create an animated GIF from three input image files, named "image1.png", "image2.png", and "image3.png". The resulting animated GIF will have a delay of 10 milliseconds between each frame and will be saved as "animation.gif" (or whichever filename is specified in place of "${animation-gif}").

Here is a breakdown of the command:

• "convert" is the command to execute the ImageMagick software.
• "${image1-png}", "${image2-png}", and "${image3-png}" are placeholders for the actual file names of the three input image files. For example, if the actual file names are "cat.png", "dog.png", and "bird.png", you would replace "${image1-png}", "${image2-png}", and "${image3-png}" with "cat.png", "dog.png", and "bird.png", respectively.
• "-delay ${10}" sets the delay between each frame of the animated GIF to 10 milliseconds. You can change 10 to a different value if you want a different delay.
• "${animation-gif}" is a placeholder for the desired output filename for the animated GIF. Replace it with the actual name you want to give to the file when saving it, such as "animation.gif".
