wyvern

A command-line image processing tool written in Rust.

This tool has been tested with .png and .jpg files. Support for other formats has not been verified yet!

Features:

• Image downscaling (50% downscaling only for now)
• Batch downscaling of a directory of images
• Fast approximate k-means clustering to get the 'common colors' of an image, output as a new image
• Edge detection for a given image
• Pixel sorting with an option to select the 'direction' of the sorted pixels
• Denoise an image using nearest-neighbor averages

Examples

Downscale a single image

The new downscaled image will be saved under \path\to\image_downscaled

wyvern image-downscale "\path\to\image"

Batch downscale a directory of images

The output of this command will be saved under a new directory \path\to\directory\resized_images

wyvern batch-resize "\path\to\directory" png

Return set of common colors in an image

The output is saved under \path\to\image_common_colors

wyvern common-colors "\path\to\image"

Generate new image highlighting the edges of an image

The new image will be saved under \path\to\image_edges

wyvern edge-detect "\path\to\image"

Pixel sort an image

This will pixel sort and save the output under \path\to\image_pixelsorted

wyvern pixel-sort "path\to\image"

Denoise an image

This will denoise a given image and save the denoised output under \path\to\image_denoised

wyvern denoise "path\to\image"

As always, use the --help flag to learn more about each command and the particular flags/args you can provide.
