canvas font rendering

Recommended Posts

Hi

 

I am trying to understand what my options are when I textout to canvas.

 

LBitmap.Canvas.Context.DC.font := 'bold 24px  verdana ';

When I google I get lots of results for CSS but that is presumably not quite the same as above. I am looking to understand what this type of definition is referred to.

 

Why because I would like to  render with a text-shadow or blur or some other nice effect. I am struggling with some basic gaps in understanding.

 

Is this referred to context.font?

The bit that I don't follow is how do I go from say this

 

function drawStroked(text, x, y) {
    ctx.font = "80px Sans-serif"
    ctx.strokeStyle = 'black';
    ctx.lineWidth = 8;
    ctx.strokeText(text, x, y);
    ctx.fillStyle = 'white';
    ctx.fillText(text, x, y);
}


drawStroked("37°", 50, 150);

to this

LBitmap.Canvas.Context.DC.font := 'bold 24px  verdana ';

 

where can I find out what "'bold 24px  verdana '; " can be replaced with?

the canvas font property is the same as the css font property : it is a shorthand form for specifying 'font-family', 'font-size', 'font-style', 'font-variant' and 'font-weight' in 1 statement.

so "font: bold 24px  verdana" specifies font-weight, font-size and font-family.

all possible font attribute values at https://developer.mozilla.org/en-US/docs/Web/CSS/font   and  .../font-family
