The CanvasRenderingContext2D
.translate()
method of the Canvas 2D API adds a translation transformation to the current matrix.
Syntax
void ctx.translate(x, y);
The translate()
method adds a translation transformation to the current matrix by moving the canvas and its origin x
units horizontally and y
units vertically on the grid.
Parameters
x
- Distance to move in the horizontal direction. Positive values are to the right, and negative to the left.
y
- Distance to move in the vertical direction. Positive values are down, and negative are up.
Examples
Moving a shape
This example draws a square that is moved from its default position by the translate()
method. An unmoved square of the same size is then drawn for comparison.
HTML
<canvas id="canvas"></canvas>
JavaScript
The translate()
method translates the context by 110 horizontally and 30 vertically. The first square is shifted by those amounts from its default position.
const canvas = document.getElementById('canvas'); const ctx = canvas.getContext('2d'); // Moved square ctx.translate(110, 30); ctx.fillStyle = 'red'; ctx.fillRect(0, 0, 80, 80); // Reset current transformation matrix to the identity matrix ctx.setTransform(1, 0, 0, 1, 0, 0); // Unmoved square ctx.fillStyle = 'gray'; ctx.fillRect(0, 0, 80, 80);
Result
The moved square is red, and the unmoved square is gray.
