- In GIMP, each image that you have open is displayed in its own separate
- window. (In some cases, multiple windows may all display the same image,
- but this is unusual.) We will begin with a brief description of the
- components that are present by default in an ordinary image window. Some
- of these, in fact, can be made to disappear using commands in the
- <a class="link" href="gimp-imagewindow-menus-view.html" title="8.  The “View” Menu">View</a>
- menu; but you will probably find that you don't want to do that.
- </p>
- <ol type="1">
- <li>
- <p>
- <span class="emphasis"><em>Title Bar:</em></span>
- At the top of the image window you will probably see a emphasis bar,
- showing the name of the image and some basic information about it. The
- emphasis bar is actually provided by the windowing system, not by GIMP
- itself, so its appearance may vary with different operating systems,
- window managers, and/or themes. In the
- <a class="link" href="gimp-pimping.html#gimp-prefs-dialog" title="1.  Preferences Dialog">Preferences dialog</a>
- you can customize the information that appears here, if you want to.
- </p>
- </li>
- <li>
- <p>
- <span class="emphasis"><em>Image Menu:</em></span>
- Directly below the emphasis bar appears the Image Menu (unless it has
- been suppressed). This menu gives you access to nearly every operation
- you can perform on an image. (There are some “<span class="quote">global</span>”
- actions that can only be accessed via the Toolbox menu.) You can
- also get the Image Menu by right-clicking inside the image
- <sup>[<a id="id2583097" href="#ftn.id2583097" class="footnote">1</a>]</sup>
- , or by left-clicking on the little “<span class="quote">arrow</span>” symbol in
- the upper left corner, if for some reason you find one of these more
- convenient.
- More: most menu operations can also be activated from the keyboard,
- using Alt plus an “<span class="quote">accelerator</span>” key underlined in the
- menu emphasis.
- More: you can define your own custom shortcuts for menu actions, if
- you enable <a class="link" href="gimp-pimping.html#gimp-prefs-interface" title="1.3.  Interface"> Use Dynamic Keyboard
- Shortcuts</a> in the Preferences dialog.
- </p>
- </li>
- <li>
- <p><a id="gimp-image-window-origin"></a>
- <span class="emphasis"><em>Menu Button:</em></span>
- Clicking on this little button gives you the Image Menu, except in a
- column instead of a row. Mnemonics users who don't want the menu bar
- visible can access to this menu by pressing the
- <span class="keycap"><strong>Shift</strong></span>+<span class="keycap"><strong>F10</strong></span>
- key.
- </p>
- </li>
- <li>
- <p><a id="gimp-image-window-ruler"></a>
- <span class="emphasis"><em>Ruler:</em></span>
- In the default layout, rulers are shown above and to the left of the
- image, indicating coordinates within the image. You can control what
- type of coordinates are shown if you want to. By default, pixels are
- used, but you can change to other units, using the Units setting
- described below.
- </p>
- <p>
- One of the most important uses of rulers is to create
- <span class="emphasis"><em>guides</em></span>.
- If you click on a ruler and drag into the image display, a guideline
- will be created, which you can use to help you position things
- accurately. Guides can be moved by clicking on them and dragging, or
- deleted by dragging them out of the image display.
- </p>
- </li>
- <li>
- <p><a id="gimp-quick-mask-toggle"></a>
- <span class="emphasis"><em>QuickMask Toggle:</em></span>
- At the lower left corner of the image display is a small button that
- toggles on or off the Quick Mask, which is an alternate, and often
- extremely useful, way of viewing the selected area within the image.
- For more details see <a class="link" href="gimp-channel-dialog.html#gimp-qmask" title="2.2.4.  Quick Mask">QuickMask</a>.
- </p>
- </li>
- <li>
- <p>
- <span class="emphasis"><em>Pointer Coordinates:</em></span>
- In the lower left corner of the window is a rectangular area used to
- show the current pointer coordinates (that is, the mouse location, if
- you are using a mouse), whenever the pointer is within the image
- boundaries. The units are the same as for the rulers.
- </p>
- </li>
- <li>
- <p>
- <span class="emphasis"><em>Units menu:</em></span>
- By default, the units used for the rulers and several other purposes
- are pixels. You can change to inches, cm, or several other
- possibilities using this menu. (If you do, note that the setting of
- “<span class="quote">Dot for dot</span>” in the View menu affects how the display is
- scaled: see <a class="link" href="gimp-view-dot-for-dot.html" title="8.3.  Dot for Dot">Dot for Dot</a>
- for more information.
- </p>
- </li>
- <li>
- <p><a id="gimp-image-window-zoom"></a>
- <span class="emphasis"><em>Zoom button:</em></span>
- There are a number of ways to zoom the image in or out, but this menu
- is perhaps the simplest.
- </p>
- </li>
- <li>
- <p><a id="gimp-image-window-status-bar"></a>
- <span class="emphasis"><em>Status Area:</em></span>
- The Status Area appears below the image display. Most of the time, by
- default, it shows which part of the image is currently active, and the
- amount of system memory that the image is consuming. You can customize
- the information that appears here, by changing your Preferences. When
- you perform time-consuming operations, the status area changes
- temporarily to show what operation is being performed, and its state
- of progress.

- <table border="0" summary="Note">

- <td align="left" valign="top">
- <p>
- Note that the amount of memory consumed by the image is quite
- different from the image file size. For instance, a 69.7Kb .PNG
- image will occupy 246Kb in memory when displayed. Two reasons for
- that. First, image is reconstituted from the compressed .PNG file.
- Then, GIMP keeps a copy of the image in memory to be used by the
- Undo command.
- </p>

- </tr>
- </table>
- </div>
- </li>
- <li>
- <p>
- <span class="emphasis"><em>Cancel Button:</em></span>
- At the lower right corner of the window appears the Cancel button. If
- you start a complex, time-consuming operation (most commonly a
- plug-in), and then decide, while it is being computed, that you didn't
- really want to do it after all, this button will cancel it
- immediately.

- <a id="id2583362" class="indexterm"></a>
- <p>
- <span class="emphasis"><em>Navigation control:</em></span>
- This is a small cross-shaped button at the lower right corner of the
- image display. Clicking on it, and holding the left mouse button down,
- brings up a window showing a miniature view of the image (Navigation
- Preview), with the
- displayed area outlined. You can pan to a different part of the image
- by moving the mouse while keeping the button depressed. For large
- images of which only a small part is displayed, the navigation window
- is often the most convenient way of getting to the part of the image
- you are looking for. (See
- <a class="link" href="gimp-navigation-dialog.html" title="2.6.  Navigation Dialog">Navigation Dialog</a>
- for other ways to access the Navigation Window). (If your mouse has a
- middle-button, click-drag with it to span across the image).
- </p>
- </li>
- <li>
- <p>
- <span class="emphasis"><em>Inactive Padding Area:</em></span>
- This padding area separates the active image display and the inactive
- padding area, so you're able to distinguish between them. You cannot
- apply any Filters or Operations in general on the inactive area.
- </p>
- </li>
- <li>
- <p><a id="imagewindow-display"></a>
- <span class="emphasis"><em>Image Display:</em></span>
- The most important part of the image window is, of course, the image
- display or canvas. It occupies the central area of the window,
- surrounded by a yellow dotted line showing the image boundary, against
- a neutral gray background. You can change the zoom level of the image
- display in a variety of ways, including the Zoom setting described
- below.
- </p>
- </li>
- <li>
- <p><a id="gimp-image-window-zoom-follow-button"></a>
- <span class="emphasis"><em>Image Window Resize Toggle:</em></span>

- image window is resized.
