- <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.

- 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

- command-line application, if this is installed on the system.

-
- <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.

- <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.

- <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.

- Images above a worksheet can be saved by accessing the context
- menu, selecting the many entry and navigating the file saving
- dialog which appears.

- <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.
