First released in 1998, the Djvu file format is an alternative open file format for scanned document storage. It is specifically targeted at documents that possess text, vector graphic drawings, photos, and colored images. The format's main selling point is its high quality authoring with minimum storage space making it popular in the distribution of magazines, comics, and ebooks. This fact places it in direct competition with the pdf format by Adobe Systems. The text layer in the Djvu file format supports optical character recognition which allows for text selection, copying, and pasting from .djvu files to other text processing applications. Free browser plugins are available for most major internet browsers which allows hosted .Djvu files to be opened directly through compatible browsers.
The .svgz extension files are Scalable Vector Graphics files that have been compressed using the GZIP compression. These files support graphical elements that include transparency, animations, gradients and filters. They consist of graphics data that is put together in an XML format. Images, text and vector graphic shapes which are paths that comprise of curves and straight lines are the three kinds of graphic objects allowed by .svg extension format. Excellent dynamic and interactive images can be created using the Scalable Vector Graphics technology which has been developed by W3C (World Wide Web Consortium) SVG group in 1998 and launched in 1999. It has been used by many web designers since then for attractive graphical representation. As per W3C recommendation, SMIL is the right choice for SVG when it comes to animation. Onmouseover or Onclick assignments can also be configured for objects in the SVG graphics to handle specific animation events to make the image dynamic and interactive.
FreeFileConvert uses tuned encoding for DJVU to SVGZ conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload DJVU files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized SVGZ results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent SVGZ audio with dependable progress tracking.
The file format has a three pass compression technique in which single scanned images are divided into three separate images and compressed individually. The images are separated into background, foreground, and mask images. The Djvu file format then makes use of IW44, a wavelet based compression algorithm, to compress background and foreground images while the mask image is compressed using JB2 encoding.
The size of .svgz extension files is reduced by as much as 50 to 80 percent as compared to the standard .svg extension files. The .svgz extension images have a vector based 2 Dimensional or a 2D format. This means that the image components have been described to display the image in any size. This image just mentions that there is an X colored circle instead of having a combined circle of all the pixels. This enables more portable images to be fit in a very less space but in turn, compromises on providing the details of the image. Filter effects, nested transformations, in-built templates, clipping of paths, feasibility of extension and alpha masks are some of the main features offered by the .svgz extension format. Some browsers do not open .svgz extension files but it can be resolved configuring the server response with the correct MIME commands that include Content-Type: image/svg-xml, image/svg+xml or image/vnd.adobe.svg+xml as applicable and Content-Encoding: gzip.
