The Picture (Editing) Toolbar and Graphic Pane

If you have enabled the Picture toolbar (in View → Toolbars), it will automatically appear on the screen whenever you select a (bitmap) picture (see Figure 126). It appears either directly under the menu bar in place of the formatting toolbar or as a floating toolbar elsewhere on the screen.

Most of the same tools are available on the Graphics pane of the Properties deck of the Sidebar. A Graphics pane, like that in Figure 127, appears automatically when you select a picture.

The following table explains the individual functions on the Picture toolbar and illustrates their use with examples.

Filter	Opens the Filter toolbar, which is described in “The Graphic Filter Toolbar”. This tool is not on the Sidebar.
Graphics Mode	Use the Graphics mode (Color mode on the Sidebar) menu to change the display of the graphic from normal color to grayscale, black and white, or a watermark. This setting affects only the display and printing of the picture; the picture itself remains unchanged.
Default:	The graphic is displayed unaltered in color.
Grayscale:	The graphic is displayed in 256 shades of gray.
Black/White:	The graphic is displayed in black and white.
Watermark:	The brightness and contrast of the graphic are reduced to the extent that the graphic can be used as a watermark (background).
Color	Use the Color tool to adjust the values of the three RGB colors, the brightness, contrast, and the Gamma value. These adjustments do not affect the original picture, but the values are stored in Draw as a separate formatting set.
	You can select values from between –100% (no color) to +100% (full intensity); 0% represents the original value of the property.
Brightness	The brightness can be adjusted between –100% (totally black) and +100% (totally white).
Contrast	The contrast can be adjusted between –100% (minimum) and +100% (maximum).
Gamma	The Gamma value affects the brightness of the middle color tones. Values can range from 0.10 (minimum) to 10 (maximum) Hint: Try adjusting this value if changing brightness /contrast does not give you the result you want.
Transparency	The degree of transparency of the picture can be adjusted from 0% (opaque) to 100% (fully transparent).
Line	Opens the Line dialog. In this context, line refers to the outline of the border. See also Chapter 4 (Changing Object Attributes). A subset of the tools are on the Line pane of the Sidebar and the full menu can be accessed via the three dots on that pane.
Area	Opens the Area dialog. Here you can edit color, gradient, hatching, and fills of the background area that contains the graphic—not the graphic itself. To see the background, you must set the graphic's transparency to a suitably high value. A subset of the tools are in the Area pane of the Sidebar, and the full menu can be accessed via the three dots on that pane.
Shadow	Use this tool to set a default shadow effect around the graphic. More control of the shadow is available on the Area dialog.
Crop	Use this function to crop (trim) an image. When you click on this icon, crop marks appear on the image (Figure 128). Drag one or more of these marks to crop the picture to your desired size. For more accurate cropping, see “Cropping” below. This tool is not available on the Sidebar.
