OSL ‐ Canvas System

What is a canvas

An osl canvas is an image held in memory that can be modified quickly and easily by osl.

This is to allow for fast drawing apps and other applications that would not be possible otherwise

Manage your canvases

canv "create" id width height #colour
// creates a new canvas (used for rendering)
// much faster than the uri commands

canv "remove" id
// deletes the canvas

canv "expand" id width height #colour
// resizes the image with #colour filling in the added parts

canv "stretch" id width height
// stretches the canvas

Get data about canvases

log id.canvWidth()
log id.canvHeight()
// log the width and height of the canvas with this specific id

log id.canvPixels()
// log the number of pixels in the canvas

log id.canvData()
// log the data uri of the canvas

Set and get pixels

canv "set_pixel" id index #colour
// update the canvas pixel at index in "id" to #colour

log id.canvPixel(index)
// log the colour of the pixel at a specific index
