The command "jpegtran -transpose" is used to rotate a JPEG image by 90 degrees clockwise. Let's break down the command into its components:
- "jpegtran": It is a command-line utility used for lossless transformations of JPEG images.
- "-transpose": This option specifies the transformation to be performed, i.e., the transpose operation, which rotates the image by 90 degrees clockwise.
- "${path-to-image-jpg}": This should be replaced with the actual path and filename of the input JPEG image you want to rotate.
- "> ${path-to-output-jpg}": This part redirects the output of the command to a new file specified by "${path-to-output-jpg}". It will create a new JPEG file with the rotated image.
Overall, this command takes an input JPEG file, applies the transpose transformation to rotate the image, and saves the result to a new JPEG file specified by the output path.
