A Node.js utility for generating animated gifs, inspired from scrolling text used as context titles in film. In the 80s and 90s you'd often see this text rendered with a kind of typing effect - as though it were being typed into a console, printed on a teletype, or recieved character by character via some transmission.
NodePTR accepts a sequence of text and writes an animated gif based on it. A simple markup syntax can be used to blink or highlight individual words, or to trigger a screen distortion effect at a specific frame.
import { nptr } from '../../nodeTextRenderer.js';
nptr('myGif', {
text: 'Hello World',
columns: 10,
displayRows: 5,
scale: 5,
});The project includes a wrapper around nptr for usage on the command line.
node nptrCLI <fileName> <text> <columns> <rows> <scale>The text argument supports three flags applied to individual words: <HL>, <BL>, and <WS>, which stand for 'highlight', 'blink', and 'wipe screen'.
The flags can be combined together, must proceed the word to which they apply, and do not have closing tags like HTML/XML.
'<BL><HL>Projection\n if <HL>intruder <HL>organism reaches civilized areas\n <BL>...Entire world population infected <HL>27,000 hours from first <WS>contact. Data Stream Broken'
This text appears onscreen in the the movie 'The Thing'
Internally, NPTR consumes character definition json generated with the React Pixel Character Editor. It will write any char sets defined with that tool, but is currently hardcoded to a specific definition set.
