Images can be added, as floating graphical elements, to Gnumeric worksheets. These images will be saved as part of the file and therefore can be sent to others embedded within the spreadsheet file.
Images in several file formats can be added, but the specific list depends on the particular installation of the underlying software library, gdk-pixbuf. 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 gdk-pixbuf can be generated with the
9.2.1. Inserting Images
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.
Select the menu item in the menu
Inserting an image starts by selecting, in themenu, the 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.
Select the file containing the image
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 thebutton. This will dismiss the dialog and expose the worksheet, with the mouse pointer now converted to a thin cross-hair.
Place the image on the worksheet with the mouse pointer
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.
9.2.2. Saving Images to New Files
Images in a Gnumeric 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.
Open the context menu
The context menu is opened by placing the mouse cursor over the image and clicking one of the secondary mouse buttons.
Select the menu item
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 Save As dialog to appear.menu item is highlighted, clicking with the primary mouse button will select that entry, causing the context menu to disappear and the
Select the file name and location
The Save As 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 can be pressed which will dismiss the dialog and save the file.
9.2.3. Deleting Images
An image element, floating above a worksheet, can be deleted from the worksheet and from the Gnumeric file using the context menu. The procedure for deleting all graphical elements is the same; this procedure is explained in Section 9.1.8 ― Deleting Graphical Elements.
