How to get an array of pixel colors from an image?

Cocos

FEBRUARY 28, 2024

I’m trying to make an effect of pixels appearing with transparency and sequence (first the “darkest” then the rest of the pixels). I want to achieve the effect - “so that the pixels, like water, fill the empty mouth of the river.” But I couldn’t get the array of pixel colors.

The vertical axes of textures and picture pixels is shown above, when sampling textures in shaders, that is from top to bottom, which is top-right corner. This is consistent with how most image file formats store pixel data, and with how most graphics APIs work (including DirectX, Vulkan, Metal, WebGPU, but not OpenGL).

First, we get the uv of the surrounding pixel through the offset uv.

Issue with masking a render Texture

Hello all, I have a shader that takes the alpha value of one texture and applies to a sprite frame. Do render Textures not support alpha in cocos? Basic masking functionality without using the mask component.

Also, take a look at the sprite data of the images that are showing up black… are any of them abnormally large? not file size large, but actual pixel size… if you have anything over 2k, I’d highly recommend making it smaller and testing. )

The black border is due to the fact that in the WebGL program, when drawing, the texture object’s Filter is set to gl.Linear (linear filtering), when a semi-transparent pixel is sampled adjacent to a fully transparent pixel during pixel interpolation (e.g.,(0.1)).0， 0) of this kind) produces black or white pixels.

To explain the idea of how shaders work, let's consider a very simple shader for drawing a sprite to the screen. Our sprite is 32x32 pixels in size, and it must be drawn at some position. The following OpenGL code sends the sprite to the shader for drawing: OpenGL Commands. Configuration parameters are sent via uniforms.

The most commonly used method involves rendering the camera to a RenderTexture (RT) and then displaying it on a Sprite. Analysis of 2D Post-Processing Solutions Cocos Creator currently lacks built-in support for post-processing in the 2D render phase, requiring developers to explore various approaches to achieve the rendering goals.
