How to add text into canvas - text

Question

I have problem with canvas fillText function. I have this code :
scene.shapes['shop1'] = new Shape();
var ps1 = scene.shapes['shop1'].points; // for convenience
ps1[0] = new Point(1024, 66, 10); // left bottom
ps1[1] = new Point(694, 66, 10); // right bottom
ps1[2] = new Point(694, 466, 10); // right top
ps1[3] = new Point(1024, 466, 10); // left top
// Background
scene.shapes['shop1'].polygons.push(new Polygon(
[ps1[0], ps1[1], ps1[2], ps1[3] ],
new Point(0, 0, 1),
true /* double-sided */,
Polygon.SOLID,
[177, 216, 249]
));
scene.shapes['shop1Header'] = new Shape();
var ps1h = scene.shapes['shop1Header'].points; // for convenience
ps1h[0] = new Point(1024, 400, 11); // left bottom
ps1h[1] = new Point(694, 400, 11); // right bottom
ps1h[2] = new Point(694, 466, 11); // right top
ps1h[3] = new Point(1024, 466, 11); // left top
// Background
scene.shapes['shop1Header'].polygons.push(new Polygon(
[ps1h[0], ps1h[1], ps1h[2], ps1h[3] ],
new Point(0, 0, 1),
true /* double-sided */,
Polygon.SOLID,
[175, 175, 175]
));
var x = -1024;
var y = -500;
ctx.font = '60pt Calibri';
ctx.lineWidth = 3;
// fill color
ctx.fillStyle = 'blue';
ctx.fillText('Hello World!', x, y);
But it don´t create the text and only display the shop. Do you know, how to solve this problem? Thank you very much.

Answer 1

The value of x and y is negative so you are drawing outside of the canvas. If you set x to 0 and y to 0 + font-size it will draw the text in the top left corner.
EDIT: you need to add the font size to y.
ctx.font = "60px Calibri"; // Use pixels instead of points
ctx.fillText("Hello World", 0, 60);
