Eyedropper Fill effect

The Eyedropper Fill effect (formerly the Color Picker effect) applies a sampled color to the source layer. This effect is useful for quickly picking a solid color from a sample point on the original layer or picking a color value from one layer and using blending modes to apply this color to a second layer.

This effect works with 8-bpc color.

Sample Point
The center of the sampled area.

Sample Radius
The radius of the sampled area.

Average Pixel Color
Which color values are sampled:
Skip Empty
Samples the average RGB color values, excluding those of transparent pixels.

All
Samples the average of all RGB color values, including those of transparent pixels.

All Premultiplied
Samples the average of all RGB color values, premultiplied with the alpha channel.

Including Alpha
Samples the average of all RGB color and alpha channel values. This setting results in the sampled color also containing the average transparency of the sampled pixels.

Maintain Original Alpha
Maintains the original layer’s alpha channel. If you choose Including Alpha in the Average Pixel Color menu, the original alpha is stenciled over the sampled color.

Blend With Original
The effect’s transparency. The result of the effect is blended with the original image, with the effect result composited on top. The higher you set this value, the less the effect affects the layer. For example, if you set this value to 100%, the effect has no visible result on the layer; if you set this value to 0%, the original image doesn’t show through.
