Hi, I am trying to compress a image (.png) using hexadecimal and ZLIB. When running the below code within naviserver the created file is larger then if I run standalone shell.
The sample code is as follows: ######### set file "/bench/myImage.png" set filePath "/bench/" set myFile [open $file RDONLY] fconfigure $ myFile -translation binary set content [read $ myFile ] set binData [encoding convertto utf-8 $content] set hexData [binary encode hex [encoding convertto utf-8 $content]] close $ myFile set fp [open "$filePath/myCompressedHexBlobFile.ixz" w] puts $fp [zlib compress $hexData] close $fp ######### Outputs: 846K - myImage.png 1.7M - myCompressedHexBlobFile.ixz - Executed within Naviserver 1.1M - myCompressedHexBlobFile.ixz - Executed from shell with TCLSH ######### Is Navi using a different zlib compression level, why is this happening? If I set the compression level to nine, the created file is still at 1.7mb. This is kind of a game changer, even if I source the compression script the file size is still larger then if I run it via terminal. Thanks Fox
