window.preload = function()

Hi! Thanks for making this great adapter! One question tho, is it still possible to used the preload function in processing in weapps using this library? I am trying to preload some images to use for later in the app. Thanks again!

@mchangxe Thks!

The preload() function mechanism is normal as p5.js.

But I found that when loadImage() in preload, the image will not be shown after draw(). There are two reasons:

1. If preload() called, you will need call canvas.style.visibility = 'visible'; once again in setup(), otherwise all the content of the canvas will not be shown.
2. Canvas of the image created by loadImage() in preload() is not the same as the canvas in setup() or draw(). It should be something conflict with WeChat Mini Game. I'll try to find more next.
   For now you can loadPixels() in callbackFunction of loadImage(xxx, callbackFunction) in preload(), and then setup the pixels to another Image created in draw().

@mchangxe , now you can use preload and loadImage as usual! Thanks @xarray!!
Just pull the latest master branch, and you can find a loadImage example in sketch.
