Web Browser problem #4

Closed photopea closed 7 years ago

photopea commented 8 years ago

Hi, can you make it work in a web browser? I am getting a following error: PNGDecoder.js:3 Uncaught ReferenceError: require is not defined

Hello, the library cannot run in the browser directly from the source. You can either use a module bundler like browserify or webpack in your project or load it directly from a browserify CDN

By the way, can you test, if your decoder can correctly decode this file? pea

No, sorry. I haven't had time to add support for palette-based images.

@photopea I added basic support for palettes in v1.1.0. The decoded image will have two properties:

image.palette: an array of arrays. Each element contains the RGB values
image.data an array of color indexes referring to the palette array

BTW. I decided to make my own PNG parser. Unlike your library, it fully supports PNG format, including all color depths and interlacing. https://github.com/photopea/UPNG.js .

BTW. why do you develop these parsers? Do you use them in any specific product?
