Sprite from buffer

[ephraimt 2]

I am trying to display an image that I get in the form of Uint8Array.

/*
width: 640,
height: 360,
data: Uint8Array(921600) [
     89,  72, 34, 255,  97,  80, 42, 255, 105,  93, 43, 255,
    117, 105, 55, 255, 117, 106, 49, 255, 110,  99, 42, 255,
    111,  98, 31, 255, 111,  98, 31, 255, 115, 107, 22, 255,
    117, 109, 24, 255, 119, 115, 16, 255, 117, 113, 14, 255,
    127, 121, 13, 255, 131, 125, 17, 255, 144, 126, 30, 255,
    146, 128, 32, 255, 143, 131, 35, 255, 135, 123, 27, 255,
    130, 112, 26, 255, 127, 109, 23, 255, 129, 103, 32, 255,
    126, 100, 29, 255, 125,  94, 28, 255, 123,  92, 26, 255,
    121,  80, 20, 255,
    ... 921500 more items
*/

const imageTexture = PIXI.Texture.fromBuffer(data, width, height);
const sprite = PIXI.Sprite(imageTexture);

Is there something else I have to do so that the Sprite displays the Texture?

If I create imageTexture using PIXI.Loader, then it works.

Welcome to the forums

Which version of PixiJS do you use? Your code should work, I need more details.

[ephraimt 2]

"pixi.js-legacy": "^5.2.0"

Using canvas renderer.

My alternate method of creating an image Sprite is to use PIXI.Loader and then to pass the resulting resource.data to PIXI.Texture.from().

That works fine, so it seems the difference is isolated to the creation of the texture.

Oh, right, fromBuffer() doesnt work with canvas2d. Whole TextureResource subsystem werent coded for it yet, because no one needed that. Now that you've asked for it , we can have that in two months or so, because it requires to code whole system for canvas and not just one "fromBuffer", and most of the team is busy.

Thanks!

I solved it by creating an <img> from the buffer (base64) and passing that to Texture.from().

I am not asking for it. There are probably more important things for the team to work on!

Well you are kind of second person who noticed that it doesnt work, so I added to some list... maybe it'll work in later versions
