JavaScript => public function LoadRawTextureData(data: byte[]): void;
JavaScript =>public function LoadRawTextureData(data: IntPtr, size: int): void;
C# => public void LoadRawTextureData(byte[] data);
C# => public void LoadRawTextureData(IntPtr data, int size);

Parameters 参数

data	Byte array to initialize texture pixels with. 初始化纹理像素的字节组。
size	Size of data in bytes. 字节数据的大小。

Description 描述

Fills texture pixels with raw preformatted data.

用原始预格式数据填充纹理像素。

This function fills texture pixel memory with raw data. This is mostly useful for loading compressed texture format data into a texture.

该函数使用原始数据填充纹理像素。用来加载压缩的纹理格式数据到纹理。

Passed data should be of required size to fill the whole texture according to its width, height, data format and mipmapCount. Mipmaps are laid out in memory starting from largest, with smaller mip level data immediately following.

传入的数据填充整个纹理所需的大小根据它的宽、高、数据格式和mipmap数。Mipmap是在内存布局从最大值开始，较小的MIP级别的数据紧随其后。

For example, a 16×8 texture of ARGB32 type with no mipmaps can be filled with a 512-byte array (16x8x4).

例如，ARGB32类型16×8的纹理，无Mipmap，填充有512字节数组（16x8x4）。

Call Apply after setting image data to actually upload it to the GPU.

设置图像数据之后，调用Apply才实际上传到GPU。
