how to hide overflow text in container

Recommended Posts

I am working on displaying a text with background color in pixi.  I could not able to hide overflow text (see attached) .  I have added bit of related code below. Please someone help me!!

renderer(){
let style = {
breakWords: true,
wordWrap: true,
align: "center",
dropShadowAngle: 0,
dropShadowDistance: 0,
fill: textColor, //Text color
stroke: textColor, //Text color,
fontSize: textSize + "px",
fontFamily: fontFamily != null ? fontFamily : "Arial", //TODO
fontWeight: fontStyle == "bold" ? fontStyle : "normal", //TODO
fontStyle: fontStyle == "italic" ? fontStyle : "normal", //TODO
align: "center",
wordWrap: true,
cacheAsBitmap: true, // for better performance
wordWrapWidth: this.textWidth != null ? parseInt(this.textWidth) : ""
};
 
let textPIXI = new PIXI.Text(textName, style);
this.setTextPosition(textPIXI, textBackgroundColor, textDimensions);
 
 
}
 
setTextPosition(textPIXI, textBackgroundColor, textDimensions) {
if (Object.keys(textDimensions).length > 0) {
const textBackgroundGraphics = new PIXI.Graphics();
 
// Rectangle
textBackgroundGraphics.beginFill(
PIXI.utils.string2hex(textBackgroundColor)
);
 
textPIXI.x = this.textPosX + (this.textWidth/2 - textPIXI.width/2);
textPIXI.y = this.textPosY + (this.textHeight/2 - textPIXI.height/2);;
 
textBackgroundGraphics.drawRect(
this.textPosX,
this.textPosY,
this.textWidth,
this.textHeight
);
textBackgroundGraphics.endFill();
 
//Add text and backgroundcolor to the container
this.addChild(textBackgroundGraphics, textPIXI);
}
}
 
I want to hide which is outside of the box.

If you know how to use html5 canvas 2d context, you can just look inside Text class and patch it, or find already existing feature:

https://github.com/pixijs/pixi.js/blob/dev/packages/text/src/Text.js#L324

https://github.com/pixijs/pixi.js/blob/dev/packages/text/src/Text.js#L128

In general, you can just apply a Graphics mask to container with that size. Look up how masks are done in pixi: https://pixijs.io/examples/#/masks/graphics.js

If your brain is already exploding, put your example to codepen/jsfiddle or pixi-playground, post it here, and wait for someone to fix it.
