Filters

The following filters can be applied to an image. These only apply to the image as it is displayed in the Viewer, not the underlying image data.

Contrast Contrast

The contrast filter allows you to change the apparent contrast of the displayed image. Negative values reduce the contrast while positive values increase it.

The slider sets the adjustment value in the range [-255, 255] with a default value of 0.

Brightness Brightness

The brightness filter adjusts the displayed image by adding a constant value to the pixel intensities.

The slider sets the adjustment value in the range [-255, 255] with a default value of 0.

Threshold Threshold

The threshold filter converts the entire image to black and white. Pixels with an average intensity below the threshold value are converted to black and all others are converted to white.

The slider sets the threshold value in the range [0, 255] with a default value of 128.

Invert Invert

The invert filter inverts the colors displayed in the image.

Window Window

The window filter converts the image to grayscale and scales all of the intensity values to fit within the configured range of values.

The Center slider determines the midpoint of the range of valid values. This slider is in the range [0 - 256] with a default value of 128.

The Width slider sets the upper and lower bounds of the range of valid values; half of the width below the Center and half above. This slider is in the range [1 - 256] with a default value of 256.

Isolate Isolate

The isolate filter allows you to display one of the red, green, or blue channels of the image as grayscale.

The Channel slider can be adjusted to 0 (red), 1 (green), or 2 (blue).
