![]() ![]() For this reason a recent version of PowerShell is needed. (WebP conversion only) To speed up conversion from jpg to webp the script is using the 'ForEach-Object -Parallel' method.I found libwebp.dll included in XnConvert, just a matter of copy-paste (WebP conversion only) nConvert needs libwebp.dll in it's Plugins folder (folder needs to be created).(WebP conversion only) nConvert - install folder needs to be in Windows PATH variable.7-zip - install folder needs to be in Windows PATH variable.Someone more PowerShell-savvy than me could probably improve this, feel free.If you want to test this, make sure to have copies the first time if something goes bad.In my testing I found that this script is faster than Comicrack at the conversion, it takes about two thirds of the time.cbz file is unpacked -> any jpg converted to webp -> repacked. Only if the user answers 'y' to convert to webp is.At the start the user get's a question about converting to webp, and if 'y' is given as answer the script converts all.cbr files in the current folder and converts them to. Don't use it on comics already in your library unless you understand the consequenses (possible loss of metadata). I use this on my comics BEFORE adding them to Comicrack.I'm not really sure that anyone will find it useful, but I've found information in this sub useful a lot and thought that i should share what little I can back. I personally convert a lot of my comics from jpg to WebP so I added that as an option as well. Recently I started learning a bit of (very basic) PowerShell and I thought it could be useful to write a simple script that converts CBR to CBZ. If you want to do lots, you may have more success applying the changes in stages.So I've been using Comicrack for a long time and I've been lurking on this sub for a while as well. Also the more functions you apply at once, the less predictable the result. ![]() There's probably a practical limit to how many are useful, because applying a lot in one go can take a while. You'll notice you can apply several processing steps at once. ![]() If you select something by accident or just change your mind, click it in the right-hand box and select 'remove' If the function has variable parameters (not all do), then they will be displayed in the 'parameters' box, from where you can set the values. The name will be copied into the right-hand box, which contains the list of functions that will be subsequently used. In order to apply any of these to your images either just double-click, or else single-click it and then click the 'Add' button. If you fully expand out the list (click on the +'s), you'll see a large list of functions. This is where all the interesting stuff is. This is a very useful transformation in itself and may even be all you want to do in some cases.Īfter sorting that out, select the 'Transformations' tab. All common picture and graphics formats (i.e. The application supports a wide range of input and output formats of graphic files, photos and images. Secondly, select the desired output file type. XnConvert is a cross-platform XnView batch image converter and resizer with a powerful and easy to use experience. Firstly, if you want to retain your original images (recommended, because you can't undo most of the functions once they're done), make sure you're either outputting into a different directory, or else you have the 'rename' option selected in the 'Overwrite' field. The window opens on 'General' and there are a couple of important options you will want to pay attention to here. The batch processing window has two tabs - 'General' and 'Transformations'. You can also add or remove files from the list at this point, though it's not usually necessary. This will bring up the batch processing window with your selected files listed. To apply batch processing, select the files that you wish to process using the browser view of XnView, then click the 'convert' button from the toolbar (or 'Batch Processing' from the edit menu or the right-click menu). Many of the functions have configurable parameters. It is also easy to save a script of the configured functions, which facilitates convenient re-use. A large number of functions are available and multiple operations can be configured and applied in one step. The functionality is the same as NConvert, except controlled via the XnView GUI rather than the command line. Batch conversion is used for applying various graphical operations to an image, or set of images.
