Guides to the frame shelf
Five pages, written because the shelf cannot explain itself while you are using it.
A decorative edge is one of those things everybody can judge and almost nobody can specify. You know when a scallop is wrong; saying why involves an arc count, a corner remainder and a band that is a proportion rather than a measurement. These pages are where that reasoning is written down, so the controls on the tool can stay short.
They are not a manual. Two of them spend most of their length arguing that a particular frame is the wrong choice for a particular photograph, one is mostly about what this renderer will never be asked to draw, and the last two carry sizes with the page each one was read from. If you are looking for a list of features, the shelf itself is a better list than any page about it.
- Guide 1
Scallops and deckles, and where they come from
One edge came off a die and one came off a paper mould, and that is why one is judged on regularity and the other on irregularity.
The corner arithmetic, the seeded tear, and what each slider is really setting.
- Guide 2
Choosing a frame for a photograph
The amount of detail already in a picture decides how much band it can carry, and most pictures can carry less than they are given.
Thin against wide, what holds up at thumbnail size, two moves for colour, and when to close the page.
- Guide 3
Drawn frames, and photographed ones
A frame here is a few hundred bytes of numbers, which is the whole reason it can be recoloured and enlarged without asking anything of you.
What the renderer refuses to draw, why there are no photographed frames here, and the two promises this tool declines to make.
- Guide 4
White borders for Instagram, without cropping
The feed shows a portrait post larger than a square one and the profile grid crops both to 3:4, so the border you add decides what survives each view.
Real outputs at 4:5, 1:1, 3:4 and 9:16 from one landscape photo, the sizes and their source, and what this page will not promise about compression.
- Guide 5
Borders on passport and form photos
None of the official pages read for this guide asks for a border, so the useful answer is mostly when not to add one, and how to pad a photo without breaking a KB window.
Passport, e-Visa, PAN and SSC figures with their sources and check dates, white padding, byte targets and print sheets.
What the guides cover, and what they do not
The two newest pages carry outside figures — Instagram sizes, Indian form photo rules — and each one names the page it was read from and the day it was read. Those figures change; the source is the authority, not this site.
What exists today is thirty-nine generated frames in seven groups, and the pages above cover all of it. The shelf itself is the shorter route to an answer for most questions.
