Netteté

The Sharpen tool improves the clarity of an image by increasing the color contrast between pixels.

 

The basic tool settings are shown in the Tool Options panel above the Image Window. To display the full list of parameters, press the tool icon in the Tool Options panel, or right-click the image. To specify the parameter settings, enter a numerical value in the parameter’s field or use the slider.

In addition to the above-mentioned parameters, you can adjust the advanced settings that affect the shape and position of the brush marks.

 

Press the Default button to set all settings to their default values.

To enhance sharpness along a straight line, select a starting point with the left mouse button, then, while keeping Shift pressed, move the cursor to the end point and release Shift. If Shift is not released, a new line will be drawn each time the mouse is clicked over the image.
