Bug 177032 – Web Inspector: Canvas: recording parameters that include an Image should show an InlineSwatch (2D canvas)

• Component: Web Inspector
• Status: RESOLVED FIXED

[Devin Rousso]

For Image:
 - createPattern
 - drawImage
 - drawImageFromRect

For ImageData:
 - createImageData
 - putImageData
 - webkitPutImageDataHD

For CanvasPattern:
 - fillStyle
 - strokeStyle

For CanvasGradient (can also treated as an image, due to its complexity compared to a CSS color):
 - fillStyle
 - strokeStyle

[Matt Baker]

It could be good to have a popover with larger thumbnail when clicking/hovering the swatch.

r=me, nice work.

This is clever, but I don't like adding new functions to the top level namespace. I'd prefer a more boring design, like extracting this to a WI.ImageRenderer or WI.ImageUtilities class with static methods. Then if for some reason we need multiple scratchpads it is trivial to do so.

let image = WI.ImageUtilities.imageFromImageData(data)
let image = WI.ImageUtilities.imageFromScratchCanvas((context) => ...)

Nit: move closer to the use site.

Nit: extra space

Ditto.

Will address in followup to avoid making this more complex.  <https://webkit.org/b/179207>
