RandomJ: Options

General Description

This plugin enables setting global parameters used by the other plugins in the RandomJ package.

Description of Dialog Components

Generate 32-bit floating point images. If selected, result images will be 32-bit floating point images. This is useful if you do not want random numbers to be clipped and rounded to the input range. Otherwise result images will be of the same type as the input images.

Adopt brightness/contrast from input images. If selected, result images will be displayed with the same brightness and contrast settings as the corresponding input images. Otherwise the brightness and contrast will be set such that the maximum result value is mapped to the maximum displayable value, and the minimum result value is mapped to the minimum displayable value.

Close input images after processing. If selected, ImageJ always closes the input image processed by a RandomJ plugin, after the plugin has finished. This is useful when you need only the result images and not the original input images.

Save result images before closing. If selected, ImageJ always asks whether or not you want to save result images before they are closed. This is useful when you want to exclude the possibility of accidentally closing an image.

Log messaging. If selected, the RandomJ plugins will generate log messages, which appear in the log window of ImageJ. These messages give you more details on what is going on behind the scene.

Notes regarding log messages: most of them originate from the ImageScience library. In this library, the "c-dimension" (channel index) is called the "s-dimension" (spectral parameter). Also, indexing of image elements always starts at 0, as opposed to ImageJ and Image5D, which start at 1 in the z-, t-, and c-dimension. Thus, in the log window, these indices are reported shifted by 1.

Upon pressing "OK", the options are stored by ImageJ and saved to its preferences file when quitting. Every time a RandomJ plugin is used, these preferences are used. This facilitates adapting the behavior of the package to your wishes.
