Using the picture toolbar

When you insert a suitable graphic image or select one already present in the document, the Picture toolbar appears. This toolbar can be either floating or docked. The figure below shows what the Picture toolbar looks like when it is floating. Two other toolbars can be opened from this one: the Graphic Filter toolbar, which can be torn off and placed elsewhere on the window, and the Color toolbar, which opens as a separate floating toolbar.

From these toolbars, you can apply small corrections to the graphic or obtain special effects.

Filters

Table 2 provides a short description of the available filters, however the best way to understand them is to see them in action. Feel free to experiment with the different filters and filters settings. remembering that you can undo all the changes by pressing Ctrl+Z or Alt+Backspace or by selecting Edit > Undo.

The figure below shows examples of some of the changes available on the Picture toolbar.

Color

Use this dialog box to modify the individual RGB color components of the image (red, green, blue) as well as the brightness, contrast, and gamma of the image. If the result is not satisfactory, you can press Control+Z to restore the default values.

Setting the object transparency

Modify the percentage value in the Transparency box Image:TranspBox.png on the Picture toolbar to make the image more transparent. This is particularly useful when creating a watermark or when wrapping the image in the background.
