Typogram 🖼️
Typogram is a simple web app to create nice-looking, minimalistic graphics that focus on a short snippet of text for sharing on the web.
Typogram allows you to set optional headers and footers to anchor or attribute
a text or quote, and provides some minimal customization options for design
style. You can enter text in Slack-style Markdown format (with *bold*
and
_italics_
, etc.), and the parser supports a full gamut of semantic display
elements including quotes, lists, and code blocks.
To render Markdown text, Typogram uses a simple (but sufficient)
hand-written Markdown parser in /js/notation.js
that quickly parses a variant
of Markdown to JSON virtual DOM that Torus can efficiently render. This is
passed to Torus's rendering logic.
The graphic is initially created and previewed as normal DOM elements, scaled to fit the editor on smaller displays. To download/export the graphic, Typogram depends on html2canvas which (mostly correctly) emulates the DOM to render an equivalent image on a canvas, which is then converted to a PNG. There are some known bugs in html2canvas, but I don't consider this a huge issue since screen-capturing the preview usually also works as a workaround.
