Texture2D.EncodeToPNG 编码为PNG


function EncodeToPNG () : byte[]

Description描述

Encodes this texture into PNG format.

将此纹理编码为PNG格式。

The returned byte array is the PNG "file". You   can write them to disk to get the PNG file, send them over the network,   etc.

返回的字节数组是PNG “文件”。你可以把数组写到磁盘上以便得到PNG文件，并通过网络发送它们

This function works only on ARGB32 and RGB24 texture formats. The texture also has to   have Is Readable flag set in the import settings.

这个函数仅在纹理格式为ARGB32和RGA24的情况下工作，并且纹理要要在倒入设置中设置为

Is Readable （可读）

The encoded PNG data will contain alpha channel   for ARGB32 textures, and no alpha channel   for RGB24 textures. PNG data will not contain gamma   correction or color profile information.

ARGB32格式的PNG纹理包含alpha通道信息，RGB24格式的纹理则没有alpha通道信息，PNG数据不包含伽玛修正或颜色配置信息
