TexturePacker版本 4.2.1
前言：因爲水平有限，錯誤再所難免，望指正, 大家如果有購買能力的話，希望購買TexturePacker正版，不要再用盜版了。好東西就應該支持。
1.安裝TexturePacker Command Line Tool
1.1 Mac下安裝 TexturePacker => Install Command Line Tool => Install
1.2 win下安裝 必須配置環境變量。
2.TexturePacker命令說明(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 PNG (32bit)
png8 PNG (8bit indexed)
pvr3 PowerVR Texture Format, PVR Version 3
pvr3gz PowerVR Texture Format, PVR Version 3, compressed with gzip
pvr3ccz PowerVR Texture Format, PVR Version 3, compressed with zlib, cocos2d header
jpg JPG image format, lossy compression, no transparency
bmp 24 bit BMP
tga Targa Image Format
tiff Tagged Image File Format
pkm PKM image format, ETC1 compression
webp WebP lossless / lossy format
atf Adobe Texture Format
pvr2 PowerVR Texture Format, PVR Version 2, deprecated
pvr2gz PowerVR Texture Format, PVR Version 2, compressed with gzip, deprecated
pvr2ccz PowerVR Texture Format, PVR Version 2, compressed with zlib, cocos2d header, deprecatepng全平臺都適用，
png8文件小但效果比起png來說有一些損失，並且對一些圖片漸變處理效果損失更加明顯，如果效果看不過去還是用png吧
pvr3ccz pvr3ccz是pvr2ccz升級版，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 主要用於ETC1
jpg 由於沒有alpha通道，所以常用於背景圖，壓縮到80%的效果和原圖差距不大，但壓縮比例很嚇人，文件小效果好，目前背景沒有alpha通道的就用的這個。由於在cocos2d 2.x版本上加載速度慢，並且消耗內存大，根據實際情況選用。
2.2 --opt 像素格式
--opt <pixelformat> Optimized output for given pixel formats. Supported formats are:
RGBA8888 32bit, 8bit/channel, 8bit transparency
BGRA8888 32bit, 8bit/channel, 8bit transparency
RGBA4444 16bit, 4bit/channel, 4bit transparency
RGB888 24bit, 8bit/channel, no transparency
RGB565 16bit, 5bit red, 6bit green, 5bit blue, no transparancy
RGBA5551 16bit, 5bit/channel, 1bit transparancy
RGBA5555 20bit, 5bit/channel, 5bit transparancy
PVRTCI_2BPP_RGB PVRTC compression, 2bit per pixel
PVRTCI_4BPP_RGB PVRTC compression, 4bit per pixel
PVRTCI_2BPP_RGBA PVRTC compression, 2bit per pixel
PVRTCI_4BPP_RGBA PVRTC compression, 4bit per pixel
PVRTCII_2BPP PVRTC2 compression, 2bit per pixel
PVRTCII_4BPP PVRTC2 compression, 4bit per pixel
ALPHA 8bit transparency
ALPHA_INTENSITY 8bit intensity, 8bit transparency
ETC1_RGB ETC1 compression
ETC1_A ETC1 Alpha channel only
ETC1_RGB_A ETC1 RGB + ETC1 Alpha
ETC2_RGB ETC2 compression
ETC2_RGBA ETC2 Alpha
DXT1 Compressed with DXT1, 1 bit transparency
DXT5 Compressed with DXT5, transparency
ATF_RGB ETC1+DXT1+PVRTC4, no transparency
ATF_RGBA ETC1/ETC1+DXT5+PVRTC4, no transparency
RGBA8888 效果最好消耗內存比較大。 內存消耗32bpp
RGBA4444 效果比起RGBA8888在某些圖片上丟失得有點大。 但消耗內存是 RGBA8888的一半。 內存消耗16bpp
RGB888 少個alpha通道，內存佔用是 RGBA8888 的 四分之三。內存消耗24bpp
RGB565 效果上比 RGB888差一些，但對於有些圖片還是可以接受的， 但沒有alpha通道。內存消耗16bpp
RGBA5551 對於透明漸變少的可以採用效果 比 RGBA4444好。內存消耗16bpp
RGBA5555 alpha通道增加 自然透明效果好了，但內存消耗也增加了。 仙存消耗24bpp
PVRTCI_4BPP_RGBA 效果上比RGBA8888要差一些，但內存消耗極小，加載速度也快，渲染速度快，在ios上完全是可以接受的，強烈建議ios 用這個格式。內存消耗4bpp
ETC1_RGB 消耗內存極小，加載速度比RGBA8888快，渲染速度快，效果也比較不錯，但沒有alpha通道，這也是ETC1被一直吐槽的點，所以後來有個ETC2。內存消耗4bpp
ETC1_A 和ETC1_RGB 組合在一起用，給ETC1_RGB提供alpha通道，達到透明效果，建議android可以選用這種方法來處理ETC1沒有alpha通道的缺點。內存消耗4bpp
ETC1_RGB、ETC1_A可以通過shader對紋理進行兩次採集處理達到RGBA的效果，這裏就不討論這個問題了。
內存消耗計算方式 ：假如一張圖是 1024 * 888
ETC1內存消耗 = 1024 * 888 * 4bpp / 8 = 454656byte = 444KB
PVRTCI_4BPP_RGBA內存消耗 = 1024 * 888 * 4bpp / 8 = 454656byte = 444KB
RGB888內存消耗 = 1024 * 888 * 24bpp / 8 = 2727936byte = 2664KB
RGBA8888內存消耗 = 1024 * 888 * 32bpp / 8 = 3637248byte = 3552KB
RGBA4444內存消耗 = 1024 * 888 * 16bpp / 8 = 1818624byte = 1776KB
2.3 --data 輸出紋理文件的信息數據路徑 plist
--data <filename> Name of the data file to write2.4 --sheet 輸出圖集路徑
--sheet <filename> Name of the sheet to write, see texture-format for formats available2.5 --dither-type 顏色抖動
--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對圖片顏色進行一些插值處理。不同參數算法不同。
PngQuantLow,PngQuantMedium,PngQuantHigh選用PNG8 可以試試這三個參數。用了比原PNG8好

其他方式比如unity,unreal,spritekit如果有用的可以自行研究
2.7 --multipack 多圖集打包
--multipack Create multiple sprite sheets if not all sprites match into a single one2.8 --maxrects-heuristics

--maxrects-heuristics Heuristic for MaxRects algorithm
Best Best
ShortSideFit ShortSideFit
LongSideFit LongSideFit
AreaFit AreaFit

2.9 --enable-rotation 精靈旋轉
--enable-rotation Enables rotation of sprites (overriding file format's defaults)2.10 --trim-mode 透明像素處理
--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 刪除圖片透明像素，用原圖片像素大小，在幀動畫中常用，
None 保證原樣大小，和透明像素。 不建議用。圖集大。
Crop 刪除圖片透明像素，用刪除後的圖片像素大小，位置改變
CropKeepPos 刪除圖片透明像素，用刪除後的圖片像素大小，位置不變
Polygon 多邊形方式，得到圖集更小，目前cocos2d 也不支持多邊形精靈。
建議使用Trim，其他用處不大。
2.11 --basic-sort-by 和 --basic-order
Basic
--basic-sort-by Sort order for the sprite list
Best Best
Name Name
Width Width
Height Height
Area Area
Circumference Circumference
--basic-order Sorting direction
Ascending Ascending
Descending Descending選用 Name 和 Ascending就行了。這個我覺得不用多做了解，按名稱升序方式排序在 list中
2.12 --max-size 最大紋理圖集大小
--max-size <int> Sets the maximum width and height for the texture in auto size mode, default is 2048建議使用2048，最大不超過4096，各個機型支持圖集大小有區別。 以前
2.13 --size-constraints 圖集高寬約束方式
--size-constraints <value> Restrict sizes
POT Power of 2 (2,4,8,16,32,...)
WordAligned Texture width is multiple of 2 (for 16-bit formats)
AnySize Any sizeAnySize 任意大小
2.14 --force-publish
--force-publish Ignore smart update hash and force re-publishing of the files強制重新再次生成，忽略智能更新，廢棄以前的 --smart-update
2.15 --shape-padding 和 --border-padding
--shape-padding <int> Sets a padding around each shape, value is in pixels, default is 2
--border-padding <int> Sets a padding around each the border, value is in pixels, default is 2--shape-padding 邊框填充像素
--border-padding 相當於精靈之間的間距像素
2.16 --scale 和 --scale-mode精靈縮放
--scale <float> Scales all images before creating the sheet. E.g. use 0.5 for half size
--scale-mode <mode> Use mode for scaling:
Smooth Smooth
Fast Fast (Nearest Neighbor)
Scale2x Scale2x (fixed 2x upscaling)
Scale3x Scale3x (fixed 3x upscaling)
Scale4x Scale4x (fixed 4x upscaling)
Eagle Eagle2x (fixed 2x upscaling)
Hq2x Hq2x (fixed 2x upscaling)主要用於不同 分辨率的機型和處理紋理大小，如果只用一套資源來適配。不用關心。scale 設爲1就行
