Color Picker Tool
The Color Picker Tool is used to transfer a color from the active layer to either of the Primary or Secondary color slots.
To use the tool, activate it and click on the active layer.
The color of the pixel under the cursor will be installed to the Primary color ( Left Mouse button )
or the Secondary color ( Right Mouse button ).
Transferring the color of a pixel in the active layer to the Primary color slot.
The Color Picker Tool is easiest to use when zoomed in on an image with the Pixel Grid enabled.
The Color Picker Tool has two sampling modes, Image and Layer.
These dictate which pixels will be sampled when picking a color.
Image - pixels are polled from the composite image when determining the color to install in the color slot.
This mode will operate in the same way as if a multi-layered image was flattened prior to using the Color Picker Tool.
Layer - pixels only within the active layer are polled to determine which color will be installed in the color slot.
This is the same sampling mode as found in previous versions of paint.net.
The Color Picker Tool has six sampling sizes that can be used. These are squares in the sizes one pixel, 3x3, 5x5, 11x11, 31x31 and 51x51.
The size determines the area that will be polled when determining the color that is installed.
Where a range of colors is covered by the sample size, the colors will be averaged and a single hue returned.
The Color Picker Tool has three actions which can be performed following the picking of a color.
