• Imagick::transposeImage — Creates a vertical mirror image
• Imagick::transverseImage — Creates a horizontal mirror image

ImageMagick manual

https://imagemagick.org/api/magick-image.php#MagickTransposeImage

• MagickTransposeImage MagickTransposeImage() creates a vertical mirror image by reflecting the pixels around the central x-axis while rotating them 90-degrees.
• MagickTransverseImage MagickTransverseImage() creates a horizontal mirror image by reflecting the pixels around the central y-axis while rotating them 270-degrees.

Point out

The imagick manual omits too much explanation and has a different meaning from the ImageMagick API.

Sample image.

vertical mirror image	horizontal mirror image

vertical mirror image, rotating 90-degrees	horizontal mirror image, rotating 270-degrees

explanation omits too much

Make sense. What do you think about the following replacement? We need short description by one line, but not omitting too much.

- Imagick::transposeImage - Creating horizontal mirror image, rotating 270-degrees

How about this? (honer the ImageMagick API manual)

• Imagick::transposeImage — Creates a vertical mirror image white rotating 90-degrees.
• Imagick::transverseImage — Creates a horizontal mirror image white rotating 270-degrees.

My previous explanation was not good.

transposeImage	transverseImage
vertical mirror	rotating 270-degrees
rotating 90-degrees	horizontal mirror

In terms of operations, transpose is the flip of x,y-asix, transverse is the reverse of all pixels, so "mirror & rotate" sentense represent only the effect.

Maybe the use of "while" to ambiguous the order of processing is intentional.
