Apply In Blur |
• Menubar | Filters > Blur > Blur |

Apply |
You can select the blur radius. The higher the radius, the more blurred the results. If you use a higher blur radius, you may see artifacts along the boundaries of This filter is not supported with Ptex channels. |
Apply Gamma |
• Menubar | Filters > Gamma |
Changes the gamma levels in the selection. |
Apply Gamma |
Do Inverse reverses the gamma conversion. That is, a higher setting for Gamma results in a more washed-out looking image. |
Apply sRGB To Linear |
• Menubar | Filters > sRGB To Linear |
Applies an sRGB to linear colorspace conversion. |
Apply sRGB To Linear |
Checking Invert applies a linear to sRGB colorspace conversion. |
Apply Hue filter |
Menubar | Filters > Hue | Changes the hue, saturation, and value of the colors on the model. |
Apply Hue |
To change the hue of the colors, set the value for Hue. This moves the • Saturation - how much saturation is applied. Select a multiplier from 0 to 2, where 1.00 is the original saturation value. • Offset - an offset value to add to the initial You can also edit the |

Apply Clamp filter |

Apply Clamp |

Apply Levels filter |
Menubar | Filters > Levels | Changes the color levels in the paint, by setting the white point, midtone, and black point. | Apply Levels |
You can change the levels of all color components or each color component • Color Component - whether this affects all color components, or a specific one (Red, Green, or Blue). • White Point - the upper limit of displayed color • Midtone - the middle point between white and black. Mari remaps the values so that this is the middle of the range between the white point and black point. Moving this pushes the values towards that end of the spectrum. • Black Point - the lower limit of displayed color intensity. Areas with a value lower than this are mapped to 0 (black). |
|
|
|
|
• White Output Level - how strongly to output the white in the filtered image. Higher values show the entire white output, lower values show decreasing amounts. • Black Output Level - how strongly to output the black in the filtered image. Higher values show the entire black output, lower values show decreasing amounts. |
Apply Color Curves filter |
• Menubar | Filters > Color Curves |
Changes the color curve for each color |
Apply Color Curves |
You can also edit each color curve, controlling how each color • pulling the anchor points, • clicking between anchor points to add a new anchor point, • right-clicking to select from a set of preset |

You can set the kernel size (the amount of filtering) by adjusting the Radius. If you use a large radius, you may get slight lines on the boundaries between patches. This is an artifact of the way that Mari handles patch edges. This filter is not supported with Ptex channels. |
