### 7.4. Hurl

#### 7.4.1. Overview

Rysunek 17.159. Example for the „Hurl” filter

Original image

Filter applied

The Hurl filter changes each affected pixel to a random color, so it produces real random noise. All color channels, including an alpha channel (if it is present) are randomized. All possible values are assigned with the same probability. The original values are not taken into account. All or only some pixels in an active layer or selection are affected, the percentage of affected pixels is determined by the Randomization (%) option.

  These options are described in Sekcja 2, „Common Features”.

Randomization (%)

  This slider represents the percentage of pixels of the active layer or selection which will be hurled. The higher value, the more pixels are hurled.

Repeat

  It represents the number of times the filter will be applied. In the case of the Hurl filter it is not very useful, because the same results can be obtained faster just by using a higher Randomization (%) value.

Random seed, New Seed

  This option controls the randomness of the filter. The Random seed box lets you manually enter a seed for the randomization algorithm used. You can also generate a random seed by pressing the New Seed button. If the same random seed is used in the same situation, the filter produces exactly the same results. A different random seed produces different results.
