Image diff viewer

Replaces the built in image viewer for jpeg and png images.

Features

• Scroll to zoom
• Click & drag pan
• Sync panning when viewing diff
• Highlight differences with mask from pixelmatch!

Commands

• Toggle diff mask - Should toggle the diff mask in the active diff view.
• Toggle swipe mode - Should toggle between a stacked swipe viewing mode.
• Diff last opened images - Will force link last two opened webviews. If vscode opens a diff and your images aren't linked with diff and sync then this is the workaround.

Note that the extension API doesn't allow to directly get the active webview so detection is based on visibility state changes. Therefore toggle commands might be sketchy.

Extension Settings

• image-diff.viewer.minScaleOne - Will always have 1 or less as the minimum scale
• image-diff.viewer.imageRendering - Sets the image-rendering css property on the image
• image-diff.diff.defaultAlign - Sets the default diff alignment for images with different dimensions.

Known Issues

• The swipe mode suffers from transform and scaling limits that don't allow for the images to pan naturally and isn't correct for the view

This extension is in very early days. And it's subject to change anytime.
