Create padding image filter

[jmooring]

Return an image resource that you can use with images.Text and images.Overlay.

images.Create WIDTH HEIGHT [BGCOLOR] [FORMAT]

• Width and height must be in the range [1,10000] (or something smaller, but put a limit on it).
• Background color is RGBA, with length of 3, 4, 6, or 8 (e.g., #123, #123f, #112233, #112233ff. If alpha not specified, opaque. Default is white.
• Format is one of jpeg, webp, etc. Default is png.

The way to handle this today is with a 1x1.png in the assets directory that you grab as a resource and then resize.

EDIT: Rethinking this, the specific case referenced above, image padding, would probably be handled better with an image filter.

images.Pad D1 [D2] [D3] [D4] [BGCOLOR]

Where the dimensions use the same syntax as CSS padding (e.g., if you provide one number if affects all sides), and background color is as previously described.

That would be useful, but we cannot re-invent the wheel here, so I suggest:

{{ $image := images.Create "200x200 jpg #000" }}

Which is the same "string API" we use in Process etc.

The way to handle this today is with a 1x1.png in the assets directory that you grab as a resource and then resize.

That said, I say that the common way today is to use a pretty background image (with some gradient or something) for your overlay images, which is trivial to make in most photo editors.

Agreed. The primary use case behind this suggestions is padding an image, which today is get+resize+get+overlay.

Instead of doing create+get+overlay, maybe just a filter so you can do get+pad.

Renaming this issue; the ability to pad an image is the primary use case. We can revisit image creation at a later date if needed.
