bopaBoalo

→ createGraphics()

Creates a hidden drawing buffer — a second canvas you draw into first.

bopaBoalo(bophara, boleele)

Call bopaBoalo(bophara, boleele) to make a buffer nobody can see. You draw into it off to one side, then stamp it onto the main canvas. It helps when you want to draw something once and reuse it many times, or simply to keep your code in parts.

Draw into the buffer. Pass it and an operation keyword to dirisaMoGo: dirisaMoGo(boalo, thalaKhutlonne, 20, 20, 60, 40). The remaining arguments belong to that operation. See dirisaMoGo for supported drawing, styling, text, transform and pixel operations.

Nothing shows until you stamp it. The buffer’s canvas is added to the page but hidden; nothing appears until you use thalaSetshwantsho(boalo, x, y). A buffer is a picture, so the word that draws it is the same word that draws any picture.

Parameters

Name	Type	Description
`bophara`	`palo`	Width of the buffer in pixels.
`boleele`	`palo`	Height of the buffer in pixels.

Examples

Draw a badge once, stamp it ten times
