Compression
Current Version: 10.1.2
Implements the Bzip2, Deflate, and LZW compression algorithms.
Object Creation
set myCompression [new CkCompression]
Properties
Algorithm
# ckStr is a CkString
CkCompression_get_Algorithm $myCompression $ckStr
set strVal [CkCompression_get_algorithm $myCompression]
CkCompression_put_Algorithm $myCompression $strVal
Specifies the compression algorithm: "deflate", "zlib", "bzip2", or "lzw". Note that "ppmd" is deprecated and should not be used. It was only available for 32-bit systems and specifically used the "J" variant. Please transition to one of the recommended algorithms.
topCharset
# ckStr is a CkString
CkCompression_get_Charset $myCompression $ckStr
set strVal [CkCompression_get_charset $myCompression]
CkCompression_put_Charset $myCompression $strVal
Only applies to methods that compress or decompress strings. This specifies the character encoding that the string should be converted to before compression. Many programming languages use Unicode (2 bytes per char) for representing characters. This property allows for the string to be converted to a 1-byte per char encoding prior to compression.
topDebugLogFilePath
# ckStr is a CkString
CkCompression_get_DebugLogFilePath $myCompression $ckStr
set strVal [CkCompression_get_debugLogFilePath $myCompression]
CkCompression_put_DebugLogFilePath $myCompression $strVal
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
DeflateLevel
set intVal [CkCompression_get_DeflateLevel $myCompression]
CkCompression_put_DeflateLevel $myCompression $intVal
This property allows for customization of the compression level for the "deflate" and "zlib" compression algoirthms. ("zlib" is just the deflate algorithm with a zlib header.) A value of 0 = no compression, while 9 = maximum compression. The default is 6.
topEncodingMode
# ckStr is a CkString
CkCompression_get_EncodingMode $myCompression $ckStr
set strVal [CkCompression_get_encodingMode $myCompression]
CkCompression_put_EncodingMode $myCompression $strVal
Controls the encoding expected by methods ending in "ENC", such as CompressBytesENC. Valid values are "base64", "hex", "url", and "quoted-printable". Compression methods ending in ENC return the binary compressed data as an encoded string using this encoding. Decompress methods expect the input string to be this encoding.
topLastErrorHtml
# ckStr is a CkString
CkCompression_get_LastErrorHtml $myCompression $ckStr
set strVal [CkCompression_get_lastErrorHtml $myCompression]
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
# ckStr is a CkString
CkCompression_get_LastErrorText $myCompression $ckStr
set strVal [CkCompression_get_lastErrorText $myCompression]
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
# ckStr is a CkString
CkCompression_get_LastErrorXml $myCompression $ckStr
set strVal [CkCompression_get_lastErrorXml $myCompression]
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
set boolVal [CkCompression_get_LastMethodSuccess $myCompression]
CkCompression_put_LastMethodSuccess $myCompression $boolVal
Indicates the success or failure of the most recent method call: 1 means success, 0 means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
topUtf8
set boolVal [CkCompression_get_Utf8 $myCompression]
CkCompression_put_Utf8 $myCompression $boolVal
When set to 1, all "const char *" arguments are interpreted as utf-8 strings. If set to 0 (the default), then "const char *" arguments are interpreted as ANSI strings. Also, when set to 1, and Chilkat method returning a "const char *" is returning the utf-8 representation. If set to 0, all "const char *" return values are ANSI strings.
topVerboseLogging
set boolVal [CkCompression_get_VerboseLogging $myCompression]
CkCompression_put_VerboseLogging $myCompression $boolVal
If set to 1, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is 0. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.
topVersion
# ckStr is a CkString
CkCompression_get_Version $myCompression $ckStr
set strVal [CkCompression_get_version $myCompression]
