If you’re interested in creating and publishing your own comic or graphic novel and distributing it online, you will probably want to use these formats they’re the most common, they’re easy to create and are recognized by most comic book readers.Īs well as often being available in print, comics are now regularly found as part of websites, on computers, mobile phones and tablets. Websites for the comics’ artists and writers will regularly feature these tales, for instance, often in CBR or CBZ format for use with a comic book reader application. The Internet has also been kind to comic book creators (although piracy has inflicted a big dent in the profits of the major publishers) and web comics and sequential art tales created specifically for an online audience are readily available. Music can be easily purchased and downloaded via iTunes, books can be purchased from Amazon and other online retailers for reading either on paper or as eBooks, movies can be purchased online and downloaded even computer games can be acquired via digital delivery services. Using the image information function in some expensive graphics programs is not reliable as they just report the file type as being whatever file extension the file has.One of the most fascinating aspects of how the World Wide Web has improved our lives can be found in the revolutions that have taken place in entertainment media.

GIMP image information also reports these “webp” images as jpegs.

This means the converted image is not a webp but some other file type with an incorrect and blatantly falsified webp extension. However, it will open the converted “webp” files made by cbxconverter complete with the false webp file extension. My installation of GIMP doesn’t have the webp library and won’t open webp files.

webp doesn’t compress in the same way so no there is no quantiser matrix from which a quality estimate can be made.) (jpeg quality is not recorded in a file but can estimated by examining the luminance quantizer matrix. When I load a real webp image it doesn’t give a warning and reports it as webp format without an estimate of the quality level. The information page reports it as using jpeg compression with an estimate of the quality level. Proof follows.Īll of the converted “webp” images when opened in irfan give me a ‘this is a jpeg with wrong file extension’ warning. See that extension? It’s saying they are in webp format but they aren’t. All of them are given a name like “page1.webp”. I have converted several hundred images using it.
