Modifying images

When you insert a new image, you may need to modify it to suit the document. This

section describes the use of the Picture toolbar, resizing, cropping, and a workaround

for rotating a picture. Changes made in Calc do not affect the original picture,

whether it is embedded or linked.

Calc provides many tools for working with images. These tools are sufficient for most

people’s everyday requirements. However, for professional results it is generally

better to use an image manipulation program such as GIMP to modify images (for

example, to crop, resize, rotate, and change color values) and then insert the result

into Calc. GIMP is an open-source graphics program that can be downloaded from

http://www.gimp.org/downloads/.

Using the Picture toolbar

When you insert an image or select one already present in the document, the Picture

toolbar appears. You can set it to always be present (View > Toolbars > Picture).

Picture control buttons from the Picture toolbar can also be added to the Standard

Toolbar. See Chapter 14 (Setting Up and Customizing Calc) for more information.

This toolbar can be either floating or docked. Figure 113 shows the Picture toolbar

when it is floating. A brief explanation of the tools is given in Table 3. See the Draw

Guide for a more detailed explanation.

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 three toolbars, you can apply small corrections to the graphic or obtain

special effects.
