TexturePacker版本 4.2.1

前言：因为水平有限，错误再所难免，望指正

1.安装TexturePacker Command Line Tool

1.1 Mac下安装 TexturePacker => Install Command Line Tool => Install

1.2 win下安装 必须配置环境变量。

2.TexturePacker命令说明(主要命令)

2.1 --texture-format

  --texture-format <id>         Sets the format for the textures.
                                The format type is automatically derived from the sheet's file name
                                if possible.
                                Available formats:

png全平台都适用， 

png8文件小但效果比起png来说有一些损失，并且对一些图片渐变处理效果损失更加明显，如果效果看不过去还是用png吧

pvr3ccz pvr3ccz是pvr2ccz升级版，添加了一些功能，可以使用其他像素格式比如 ETC1，pvr2ccz 以前是不支持的。

pkm 主要用于ETC1
jpg 由于没有alpha通道，所以常用于背景图，压缩到80%的效果和原图差距不大，但压缩比例很吓人，文件小效果好，目前背景没有alpha通道的就用的这个。由于在cocos2d 2.x版本上加载速度慢，并且消耗内存大，根据实际情况选用。

RGBA8888 效果最好消耗内存比较大。 内存消耗32bpp

RGBA4444 效果比起RGBA8888在某些图片上丢失得有点大。 但消耗内存是 RGBA8888的一半。 内存消耗16bpp

RGB888 少个alpha通道，内存占用是 RGBA8888 的 四分之三。内存消耗24bpp

RGB565 效果上比 RGB888差一些，但对于有些图片还是可以接受的， 但没有alpha通道。内存消耗16bpp

RGBA5551 对于透明渐变少的可以采用效果 比 RGBA4444好。内存消耗16bpp

RGBA5555 alpha通道增加 自然透明效果好了，但内存消耗也增加了。 仙存消耗24bpp

PVRTCI_4BPP_RGBA 效果上比RGBA8888要差一些，但内存消耗极小，加载速度也快，渲染速度快，在ios上完全是可以接受的，强烈建议ios 用这个格式。内存消耗4bpp

ETC1_RGB 消耗内存极小，加载速度比RGBA8888快，渲染速度快，效果也比较不错，但没有alpha通道，这也是ETC1被一直吐槽的点，所以后来有个ETC2。内存消耗4bpp

ETC1_A 和ETC1_RGB 组合在一起用，给ETC1_RGB提供alpha通道，达到透明效果，建议android可以选用这种方法来处理ETC1没有alpha通道的缺点。内存消耗4bpp

ETC1_RGB、ETC1_A可以通过shader对纹理进行两次采集处理达到RGBA的效果，这里就不讨论这个问题了。

内存消耗计算方式 ：假如一张图是 1024 * 888

ETC1内存消耗 = 1024 * 888 * 4bpp / 8 = 454656byte = 444KB

PVRTCI_4BPP_RGBA内存消耗 = 1024 * 888 * 4bpp / 8 = 454656byte = 444KB

RGB888内存消耗 = 1024 * 888 * 24bpp / 8 = 2727936byte = 2664KB

RGBA8888内存消耗 = 1024 * 888 * 32bpp / 8 = 3637248byte = 3552KB

RGBA4444内存消耗 = 1024 * 888 * 16bpp / 8 = 1818624byte = 1776KB

2.3 --data 输出纹理文件的信息数据路径 plist

  --data <filename>             Name of the data file to write

2.4 --sheet 输出图集路径

  --sheet <filename>            Name of the sheet to write, see texture-format for formats available

2.5 --dither-type 颜色抖动

  --dither-type <dithertype>    Dithering to improve quality of color reduced images
                                    NearestNeighbour      no dithering
                                    Linear                no dithering
                                    FloydSteinberg        Floyd Steinberg, no alpha
                                    FloydSteinbergAlpha   Floyd Steinberg, with alpha
                                    Atkinson              Atkinson, no alpha
                                    AtkinsonAlpha         Atkinson, alpha
                                    PngQuantLow           PNG-8 only: minimum dithering
                                    PngQuantMedium        PNG-8 only: medium dithering
                                    PngQuantHigh          PNG-8 only: strong dithering

对图片颜色进行一些插值处理。不同参数算法不同。 

PngQuantLow,PngQuantMedium,PngQuantHigh选用PNG8 可以试试这三个参数。用了比原PNG8好

cocos2d-x 新版本的多边形打包方式,目前cocos studio 不支持

cocos2d-v2 老版本的打包方式，现在已经被废弃，但我还是用的这个。

maxrect的算法方式

2.9 --enable-rotation 精灵旋转

--enable-rotation             Enables rotation of sprites (overriding file format's defaults)

2.10 --trim-mode 透明像素处理

  --trim-mode <value>           Remove transparent parts of a sprite to shrink atlas size and speed up rendering
                                    None              Keep transparent pixels
                                    Trim              Remove transparent pixels, use original size.
                                    Crop              Remove transparent pixels, use trimmed size, flush position.
                                    CropKeepPos       Remove transparent pixels, use trimmed size, keep position.
                                    Polygon           Approximate sprite contour with polygon path.

常用Trim。

Trim 删除图片透明像素，用原图片像素大小，在帧动画中常用，

None 保证原样大小，和透明像素。 不建议用。图集大。

Crop 删除图片透明像素，用删除后的图片像素大小，位置改变

CropKeepPos 删除图片透明像素，用删除后的图片像素大小，位置不变

Polygon 多边形方式，得到图集更小，目前cocos2d 也不支持多边形精灵。

建议使用Trim，其他用处不大。

2.11 --basic-sort-by 和 --basic-order 

    Basic
      --basic-sort-by           Sort order for the sprite list
