<title>Images</title>
<para>
Images can be added, as floating graphical elements, to
<application>Gnumeric</application> worksheets. These images will
be saved as part of the file and therefore can be sent to others
embedded within the spreadsheet file.
</para>
<para>
Images in several file formats can be added, but the specific list
depends on the particular installation of the underlying software
library, <filename>gdk-pixbuf</filename>. By default, the ANI, BMP,
GIF, ICO, JPEG, PCX, PNG, PNM/PBM/PGM/PPM family, Sun raster
(RAS), Targa (TGA), TIFF, WBMP, XBM, XPM image formats are
supported, but extensions to the library can also support other
formats such as the WMF Windows Metafile and SVG Scalable
Vector Graphics formats.
</para>
<note>
<para>
A complete listing of the file formats supported by the local
version of <filename>gdk-pixbuf</filename> can be generated with
the <screen>
gdk-pixbuf-query-loaders
</screen>
command-line application, if this is installed on the system.

<title>Inserting Images</title>
<para>
</para>
<para>
Inserting an image is performed like inserting any other
graphical element using the menu entry to start the process,
then selecting the file, and finally using the mouse to place
the image above the worksheet.
</para>
<procedure>
<title>Procedure to insert an image into a worksheet.</title>
<step>
<title>
Select the <guimenuitem>"Image"</guimenuitem> menu item in
the <guimenu>"Insert"</guimenu> menu
</title>
<para>
Inserting an image starts by selecting, in the
<guimenu>Insert</guimenu> menu, the
<guimenuitem>Image</guimenuitem> menu item using the mouse
cursor and the primary mouse button. This will open a
dialog in which the user can select the file which
contains the desired image.
</para>
</step>
<step>
<title>Select the file containing the image</title>
<para>
In the dialog which appears the user must select the file
which contains the desired image. The dialog will be
specific to the particular operating system platform but
should provide a way to navigate the filesystem to pick
the folder that contains the file and have a way to select
the file or type its name. When these choices have been
made, the dialog can be dismissed by double clicking on
the file or by clicking on the <guibutton>Open</guibutton>
button. This will dismiss the dialog and expose the
worksheet, with the mouse pointer now converted to a thin
cross-hair.
</para>
</step>
<step>
<title>
Place the image on the worksheet with the mouse pointer
</title>
<para>
The image, which will float like other graphical elements
above the worksheet, must be placed on the worksheet. The
image can be placed with its default size by
moving the thin cross-hair pointer above the worksheet and
clicking with the primary mouse button. Alternatively, the
image can be placed and sized by selecting two of the
resulting corners. This is done by moving the thin
cross-hair pointer over the worksheet, determining one
corner by clicking and holding the primary mouse button,
dragging the pointer to the opposite corner, and releasing
the mouse button. The image will then appear between the
place where the primary mouse button was pressed and the
place the button was released.

<sect2 id="sect-graphics-images-save">
<title>Saving Images to New Files</title>
<para>
Images in a <application>Gnumeric</application> worksheet can be
saved to a new, separate file. The image can be saved either in
its original format or in PNG or JPEG formats. The ability to
save images to a new file is especially useful when a
spreadsheet file has been transferred to a computer that does not
have a copy of the original image.
</para>
<para>
Images above a worksheet can be saved by accessing the context
menu, selecting the many entry and navigating the file saving
dialog which appears.
</para>
<procedure>
<title>Procedure to save a worksheet image.</title>
<step>
<title>Open the context menu</title>
<para>
The context menu is opened by placing the mouse cursor
over the image and clicking one of the secondary mouse
buttons.
</para>
</step>
<step>
<title>
Select the <guimenuitem>"Save As"</guimenuitem> menu item
</title>
<para>
Once the context menu appears, the mouse cursor can be
moved over the menu. As the cursor passes over each menu
item, that item will be highlighted. When the
<guimenuitem>Save As</guimenuitem> menu item is
highlighted, clicking with the primary mouse button will
select that entry, causing the context menu to disappear
and the <interface>Save As</interface> dialog to
appear.
</para>
</step>
<step>
<title>Select the file name and location</title>
<para>
The <interface>Save As</interface> dialog which opens will
depend on the platform that the user is using but should
be standard for that platform. The dialog should allow a
user to define a name for the file, to select the folder
(directory) in which a file will be saved, and to select
the format for the saved file. When all these selections
have been made, the <guibutton>Save</guibutton> can be
pressed which will dismiss the dialog and save the file.
</para>

<title>Deleting Images</title>
<para>
An image element, floating above a worksheet, can be deleted
from the worksheet and from the
<application>Gnumeric</application> file using the context
menu. The procedure for deleting all graphical elements is the
same; this procedure is explained in <xref
linkend="sect-graphical-overview-deleting" />.
