Scale an image and apply a mask to it

[fabriziof64]

Hi,

 

I'm working on a web app that receives jpg images from the server, and I need to resize the received image to the size of a mask .png image.

I'm trying as follows, but I don't find the way to scale the image that I get from the cache.

Can anyone help me? Thanks,

 

// get the size of the mask .png image here

var maskImage = game.cache.getImage('mainMask');
 

// make a bitmapData with that size

var bmd = game.make.bitmapData(maskImage.width, maskImage.height);

 

// get the image received from the server  that must be masked

var currImage = game.cache.getImage(cacheKey);

 

// ======>>>>>>> scale / resize / crop the currImage here to match the mask image size, and put the result into the cache

 

// apply mask

bmd.alphaMask(cacheKey, 'mainMask');

 

// create the sprite

var sprite = game.add.sprite(game.rnd.integerInRange(maskImage.width / 2, 1000), game.rnd.integerInRange(maskImage.height / 2, 1000), bmd);
