If the file format is not supported or the Binary Normalisation option is selected, Xena will perform ASCII Base64 encoding on binary files and wrap the output in XML metadata. The resulting .xena file is plain text, although the content of the data itself is not directly human-readable. The exact original file can be retrieved by stripping the ...
Since Base64 encoded data is approximately 33% larger than original data, it is recommended to use Base64 data URIs only if the server supports HTTP compression or embedded files are smaller than 1KB. The data, separated from the preceding part by a comma (,). The data is a sequence of zero or more octets represented as characters. The comma is ...
Because Base64 is a six-bit encoding, and because the decoded values are divided into 8-bit octets, every four characters of Base64-encoded text (4 sextets = 4 × 6 = 24 bits) represents three octets of unencoded text or data (3 octets = 3 × 8 = 24 bits). This means that when the length of the unencoded input is not a multiple of three, the ...
Using XOP avoids this by extracting the binary data out of the XML Infoset so that the XML Infoset does not contain binary data and the binary data can be serialized differently. Therefore, XOP can reduce the size of the serialization (since base64 encoding has approximately a 33% size overhead) and (depending on how it is implemented) might ...
XnView can read more than 500 image file formats, some audio and video file formats, and write 50 image file formats. [13] XnView also supports ICC profiles in JPEG , PNG and TIFF files. It doesn't respect loop settings on animated files, however, and will infinitely loop them, regardless. [ 14 ]
OutGuess is a steganographic software. It has handlers for image files in the common Netpbm and JPEG formats, so it can, for example, specifically alter the frequency coefficients of JPEG files. It is written in C and published as Free Software under the terms of the old BSD license.
FlatBuffers is a free software library implementing a serialization format similar to Protocol Buffers, Thrift, Apache Avro, SBE, and Cap'n Proto, primarily written by Wouter van Oortmerssen and open-sourced by Google. It supports “zero-copy” deserialization, so that accessing the serialized data does not require first copying it into a ...
Grok is a computer software library to encode and decode images in the JPEG 2000 format. It is designed for stability, high performance, and low memory usage. Grok is free and open-source software released under the GNU Affero General Public License (AGPL) version 3.
