About Total Resizer

Total Resizer (TotalRSZ) is a Packer/unpacker plugin for TotalCommander (TC). It's function is to resize image files in batch mode.

Installation:

Unzip TotalRSZ.zip, put the files in the folder where TC sits or anywhere you like. Run TC, from the menu:

	Configuration-->Options...-->Packer
	click "Configure packer extension WCXs",
	then enter "rsz" without quotes in the field of 
	"All files with extension (ending with)". Then click "New type" button, 
	select "TotalRSZ.wcx". Click "OK". That's all of it.

Usuage:

In TC, select one or more image files, then press "Alt+F5". From the opened dialog, choose rsz as the external packer. Click OK, and in the opened TotalRSZ dialog, set the appropriate parameters, then click OK. TotalRSZ will resize the image files using the parameters. The destination path is the one displayed in another pane of TC.

TotalRSZ can also operate on folders. If you select the folders, TotalRSZ will try to resize image files in all the sub-directories.

Notes:

1. About the target file name. $(FileNameNoExt) is automatically filled in the text field, which stands for the source file's name. You can add any prefix or suffix to it, for example, AAA$(FileNameNoExt)BBB. But $(FileNameNoExt) must be a part of the name.

2. About the target image format. There are two options. The first one is the same as the source file. For example, if the source file is a jpeg, then the target is also a jpeg file. The second option is to choose a specific format for all the target files. If you select multiple files to resize, then using the second option, the target files will be in the same format.

3. About the target image size. There are two options as well. The first one is to set a specific size. The second is to set a value of percentage. No mater which option is used, the aspect ratio of the image is unchanged. For example, set the target image of size 500x400, the aspect ratio is 5/4. Using the first option, if the source image's aspect ratio is also 5/4, then the source image will be scaled to the desired size. If the specified aspect ratio is not the same as the source, then the actual target image's size is determined in such a way that using one of the specified sides and the source aspect ratio, the calculated the other side is not greater than the specified value. For example, using the same values for the target image as the previous example, if the source aspect ratio is 1:1, then the target image size will be 400x400; if the source aspect ratio is 5:3, then the actual target image size will be 500x300; if the source aspect ratio is 3:4, then the actual target image size will be 300x400.
