140 CHAPTER 7 Painting and Drawing 6 Set additional options: • For the paintbrush tool, select Wet Edges to paint with a watercolor effect. The paint builds up along the edges of the brush stroke. • For the pencil tool, select Auto Erase to paint the background color over areas containing the foreground color. 7 Specify the rate at which a brush stroke fades dynamically. (See "Specifying a paint fade-out rate" on page 149.) 8 Drag in the image to paint. To draw a straight line with one of the painting tools, click a starting point in the image. Then hold down Shift, and click an ending point. Erasing The eraser and magic eraser tools let you erase areas of an image to transparency or to the background color. The background eraser tool lets you erase to transparency on a layer. You can also use the Auto Erase option with the pencil tool to erase the foreground color to the background color as you paint, unless the area does not contain the foreground color. In that case the area is painted with the foreground color. Using the eraser tool The eraser tool changes pixels in the image as you drag through them. If you're working in the background or in a layer with transparency locked, the pixels change to the background color; otherwise, the pixels are erased to transparency. To use the eraser tool: 1 Select the eraser tool ( ). 2 Choose a brush size from the pop-up palette in the options bar. To learn more about using pop-up palettes, see "Using pop-up palettes" on page 35. If a brush is too large to fit in the palette, it appears as a smaller brush with a number indicating the actual diameter in pixels. 3 Choose the tool Mode you want to use as an eraser-paintbrush, airbrush, pencil, or block. 4 Specify an opacity to define the strength of the erasure. An opacity of 100% erases pixels to complete transparency. A lower opacity erases pixels to partial transparency. (This option is not available for block mode.) 5 If you're using the paintbrush eraser, select Wet Edges to erase with a watercolor effect. When this is selected, the erased effect builds up along the edges of the brush stroke. 6 Specify the rate at which a brush stroke fades dynamically. (See "Specifying a paint fade-out rate" on page 149.) 7 Drag through the area you want to erase. Using the magic eraser tool When you click in a layer with the magic eraser tool, the tool automatically changes all similar adjacent pixels. If you're working in the background, or in a layer with locked trans-
