IIPImage动态水印

Question

作为开始，有人能为IIPImage做个标签吗？http://iipimage.sourceforge.net/

我正试着在我的服务器上设置动态水印: IIPImage使用金字塔蒂夫成像，它将图像分割成瓦片。动态水印在瓷砖上随机添加水印，要做到这一点，你必须在Server.conf文件中指定3个变量，该文件保存在启用Apache2模块的目录中。水印与你的水印的位置，有多少块将有水印，即0.3 = 30%，最后WATERMARK_OPACITY它是不透明的。http://iipimage.sourceforge.net/documentation/images/#watermarking这是我的配置：

ScriptAlias /fcgi-bin/ "/usr/lib/cgi-bin/"
# Set the options on that directory
<Directory "/fcgi-bin/">
AllowOverride None
Options None
Order allow,deny
Allow from all
</Directory>

# Set the handler
AddHandler fastcgi-script fcg fcgi fpl

# Initialise the FCGI server - set some default values
FastCgiServer /usr/lib/cgi-bin/iipsrv.fcgi \
-initial-env LOGFILE=/var/log/iipsrv.log \
-initial-env VERBOSITY=3 \
-initial-env JPEG_QUALITY=90 \
-initial-env MAX_IMAGE_CACHE_SIZE=10 \
-initial-env MAX_CVT=5000 \
-initial-env WATERMARK=/IIPServer/images/watermark.tif \
-initial-env WATERMARK_PROBABILITY=0.3 \
-initial-env WATERMARK_OPACITY=0.5 \
-initial-env MEMCACHED_SERVERS=localhost

下面是我在启动后的日志文件：

好的，所以问题是，在设置动态水印之前加载的所有图像都缓存在memcache和浏览器缓存中，清除这些缓存修复了问题。
