AddBrandingImage为installer添加一个图标，但不是icon,its size will be set according to the width/height specified,the installer'swidth/height and the installer font,the final size will not always be what you requested;AddBrandingImage only adds a placeholder for an image,to set the image itself on runtime,use SetBrandingImage2. AllowRootDirInstallcontrols whether or not installs are enabled to the root directory of a dirve,or directly into a networkshare,set to true to change the safe behavior,which prevents users from selecting C:/ or //Server/Share as aninstall(and later on ,uninstall)directory,for additional directory selection page customizability,3.

This command allows you to control thecompiler's memory usage by limiting how much of a given file it will load into memory at thecompiler needs both input and output,twice the memory size specified could be used at given time for filebuffers.48 SetCompress auto|force|off48 SetCompress auto|force|offthis command sets the compress flag which is used by the installer to determine whether or not data shouldbe compressed49 SetCompressor [/SOLID][/FINAL] zlib|bzip2|lzma;设置压缩算法，不能在section和functions中使用且必须在压缩前使用this command sets the compression algorithm used to compress filese/data in the : (the default) it is a quick and simple method, 300kb memory usesBZIP2: gives better compression raios than ZLIB but a bit slower and uses more memory,4M memory usesLZMA: a new compression method that gives very good compression ratios,compression speed is lower but

decompression speed is high ,8M memory usesif /FINAL is used,subsequent calls to SetCompressor will be ignored.即后面的调用将被忽略if /SOLID is used,all of the installer data is compressed in one block,result in greater compression ratios50 SetCompressorDictSize dict_size_mbSets the dictionary size in megabytes used by the LZMA compressor
