Mosaic

The mosaic effect resamples the image and sets every pixel to the average color of its neighbors in the new block. The block size is determined by parameters X and Y (values are between 2 and 50). If the Equal Dimensions box is checked the two parameters will have the same value.

You can place separator lines between the rectangles by switching Separator on. The color of the lines is determined by Separator Color.

Some parameters won't appear if you set Options / Preferences / Level  to Novice.

If you use this effect as a drawing mode by activating its icon on the Icon bar, you can use the brush to select the area you want to process: only image parts under your mouse's path will be altered. You won't see the small preview and the Preview, Cancel and Ok buttons. To get rid of its dialog, simply select another tool.

The small preview image instantly shows the changes you've made. You can hide it by turning switch Inst Preview off.

Be careful! The result of this effect depends on the image size, thus you may get a different image here.


Brightness/Contrast

With the panel you can change the brightness and contrast value of the image. Higher Brightness values result in a brighter, while lower values result in a darker image. The brightness value can change between -99..99. Higher Contrast values result in a higher, while lower values result in a lower contrast of the image. Values can change between -99..999.

The Optimize Histogram button examines the histogram of the image and finds the optimal settings: the brightness and contrast parameters will be set to provide the highest contrast without losing any existing color shades.

This means that the histogram will be shifted and stretched to cover the whole intensity range.

If you use this effect as a drawing mode by activating its icon on the Icon bar, you can use the brush to select the area you want to process: only image parts under your mouse's path will be altered. You won't see the small preview and the Preview, Cancel and Ok buttons. To get rid of its dialog, simply select another tool.


Posterize

The posterize effect cuts the least significant bits of each color component (channel). This means that each component is displayed in 2^(Bits/Channel) shades. The original picture has 8 bits / channel. You can decrease this down to 1 bit / channel which means 2 possible values per channel resulting in 8 possible colors.

But be careful! If you run UP in 16 bit color mode (which means that you can see only 5 bits/channel for red and blue and 6 bits/channel for green), setting the Bits/Channel value between 5 and 8 will affect the picture but the results on the screen will be invisible.


Solarize

Solarize inverts the color components of each pixel of the image that are equal or above the Threshold value. If you turn the Inverse switch on, components below the Threshold value will be inverted (you can think of it as using the normal Solarize effect and inverting the picture afterwards).


Remove Noise

You can remove dust and minor scratches from your image with this filter. The smaller the Threshold value, the stronger the effect will be. Each pixel is examined; if it differs from the average of its immediate neighbors more than the Threshold value, it is substituted with their average.

Zero Threshold value results in a blur filter.

Emboss

Apply the Emboss effect to raise and stamp the image contours by casting highlights and shadows: it will make your image look like a relief. Parameter Angle (in degrees) controls the direction of the light source, Depth determines how deep the ditches are, while Strength sets the power of the effect. If you check Gray Background, you will get the standard Emboss effect: the highlights and shadows will be drawn on a gray background. If the option is not checked, they will appear right on the original image.

The small preview image instantly shows the changes you've made. You can hide it by turning switch Inst Preview off.

Be careful! The result of this effect depends on the image size, thus you may get a different image here.


Diffuse

Apply this filter if you want to spread the points of the picture around: for each pixel the program chooses a neighbor randomly and substitutes the original color with the neighbor's. The size of the neighborhood is determined by parameter Radius. If you use Mode Darken or Lighten the new color will only replace the original one if it is darker or lighter, respectively.

By pressing button Preview you'll get the preview of the effect on the whole picture. Button Preset restores the original settings. If you press Cancel, the operation will be cancelled and the original image will be restored, while pressing the Ok button makes the change permanent.


Ice Cream

This filter gives you a funny special effect: a big ice cream-like spiral appears in the middle of the image. Parameter Angle sets the direction the light comes from. Size determines the size of the spiral - the bigger it is the more curves will appear. Transp sets the transparency level of the spiral: bigger values result in a more transparent spiral. Finally Cream Color determines the color of the spiral.

Invert Light

This effect will invert the picture in a special way. Solar Hi-Lite is the threshold of the invert effect, Control Light determines the ambient light, while True Invert is something like a contrast function here.

Color Gradient

This effect will paint a continuous color gradient over your image. You can define 4 colors for each side of the image. The component will interpolate their value and add it to the image.

It substracts 128 from each color component: 127 means -1, 128 means 0, 129 means 1, etc: thus a middle gray won't change the original colors, a lighter color brightens the given side of the image, while a dark one darkens it.

Median

This filter sorts the colors of neighboring points and picks one determined by Bias from this list. Its Radius value sets the size of the box (each side will be Radius*2+1 pixels) containing the points sorted. Bias determines which point should be retrieved: -10 means the first value (with minimum intensity), 0 means the value in the middle (this is the original median filter), while 10 gets the last value of the list (with maximum intensity).

Some parameters won't appear if you set Options / Preferences / Level  to Novice.

Arithmetic

With the help of this component you can do image arithmetic. First you should select the two images you want to work with by entering the buffer number of the images below Image 1 and Image 2. After that you should select the parameters of the operation (Source 1 and Source 2). This can be

Original	this leaves the original image as is,

Red Channel	leaves the red channel and clears all others,

Green Channel	leaves the green channel and clears all others,

Blue Channel	leaves the blue channel and clears all others,

Grayscale	converts the image to grayscale (all channels will have the same value: intensity).

Now you should decide what operation you want to perform on the selected images:

Source 1	the output will be Source 1, and Source 2 will be discarded,

Source 2	the output will be Source 2, and Source 1 will be discarded,

Addition	it gives the sum of Source 1 and Source 2,

Subtraction	the result image will be Source 2 subtracted from Source 1,

Difference	calculates the absolute value of the difference between the sources,

Multiply	multiplies Source 1 by Source 2,

Darkest	chooses the darker pixels of the sources,

Lightest	chooses the lighter pixels of the sources,

Logical XOR	the output will be Source 1 XOR Source 2,

Logical AND	the output will be Source 1 AND Source 2,

Logical OR	the output will be Source 1 OR Source 2.

Finally you can multiply the image pixel-by-pixel by a multiplier and transpose it by a bias value.

If source images have different dimensions than the destination image, they will be stretched to fit.

Some parameters won't appear if you set Options / Preferences / Level  to Novice.
