The Paint Bucket tool fills an area, that is similar in color value to the pixels you click. You can fill an area with the foreground color or a pattern.
Set options in the Tool Options bar, as desired, and then click the part of the image you want to fill.
If you don’t want to fill transparent areas in a layer, you can lock the layer’s transparency in the Layers panel.
Sets the opacity of the paint you apply. A low opacity setting allows pixels under a paint stroke to show through. Drag the slider or enter an opacity value.
Defines how similar in color filled pixels must be. A low tolerance fills pixels with color values very similar to the pixel you click. A high tolerance fills pixels that have a broader range of colors.
Fills similar pixels on any visible layer that are within the levels set by the Tolerance and Contiguous options.
Fills similarly colored pixels that are next to each other. Deselect this option to fill all similar pixels in the image, including those that aren’t touching. The Tolerance option defines how similar the colors must be.
You can use a fill layer to apply a fill or a pattern to your image, instead of using one of the brush tools. The fill layer gives you the added flexibility of changing the fill and pattern properties and editing the fill layer’s mask to limit the gradient to a portion of your image.
Choose a color from the Use menu. To select a different color, choose Color, and then select a color from the Color Picker. Choose Pattern to fill with a pattern.
Specifies the pattern to use if you choose Pattern from the Use menu. You can use patterns from the pattern libraries or create your own patterns.
You can use the Stroke command to automatically trace a colored outline around a selection or the content of a layer.
To add an outline to the background, you must first convert it to a regular layer. The background contains no transparent pixels, so the entire layer is outlined.
