You can get context-sensitive help for most of GIMP's features by
|
|
pressing the F1 key at any time. This also works inside the menus.

<tip level="beginner" help="gimp-layer-dialog">
|
|
<thetip>
|
|
GIMP uses layers to let you organize your image. Think of them
|
|
as a stack of slides or filters, such that looking through them you
|
|
see a composite of their contents.
|
|
</thetip>
|
|
</tip>
|
|
<tip level="beginner" help="gimp-layer-menu">
|
|
<thetip>
|
|
You can perform many layer operations by right-clicking on the text
|
|
label of a layer in the Layers dialog.
|
|
</thetip>
|
|
</tip>
|
|
<tip level="beginner" help="gimp-file-save">
|
|
<thetip>
|
|
Saving an image uses XCF, GIMP's native file format (file extension
|
|
<tt>.xcf</tt>). This preserves the layers and many aspects of your
|
|
work-in-progress, allowing to work on it again later.
|
|
Once a project is completed, you can export it as JPEG, PNG, GIF, etc.
|
|
</thetip>
|
|
</tip>
|
|
<tip level="beginner" help="gimp-image-flatten">
|
|
<thetip>
|
|
Most plug-ins work on the current layer of the current image. In
|
|
some cases, you will have to merge all layers (Image→Flatten Image)
|
|
if you want the plug-in to work on the whole image.
|
|
</thetip>
|
|
</tip>
|
|
<tip level="beginner" help="gimp-layer-alpha-add">
|
|
<thetip>
|
|
If a layer's name in the Layers dialog is displayed in <b>bold</b>,
|
|
this layer doesn't have an alpha-channel. You can add an alpha-channel
|
|
using Layer→Transparency→Add Alpha Channel.
|
|
</thetip>
|
|
</tip>
|
|
<tip level="beginner">
|
|
<thetip>
|
|
Not all effects can be applied to all kinds of images. This is
|
|
indicated by a grayed-out menu-entry. You may need to change
|
|
the image mode to RGB (Image→Mode→RGB), add an alpha-channel
|
|
(Layer→Transparency→Add Alpha Channel) or flatten it
|
|
(Image→Flatten Image).

You can adjust or move a selection by using <tt>Alt</tt>-drag.
|
|
If this makes the window move, your window manager uses the
|
|
<tt>Alt</tt> key already. Most window managers can be
|
|
configured to ignore the <tt>Alt</tt> key or to use
|
|
the <tt>Super</tt> key (or "Windows logo") instead.

You can drag and drop many things in GIMP. For example, dragging
|
|
a color from the toolbox or from a color palette and dropping it into
|
|
an image will fill the current selection with that color.
|

You can use the middle mouse button to pan around the image
|

(or optionally hold <tt>Spacebar</tt> while you move the mouse).

Click and drag on a ruler to place a guide on an image. All
|
|
dragged selections will snap to the guides. You can remove
|
|
guides by dragging them off the image with the Move tool.

|
</thetip>
|
|
</tip>
|
|
<tip level="intermediate" help="gimp-file-new">
|
|
<thetip>
|
|
You can drag a layer from the Layers dialog and drop it onto the
|
|
toolbox. This will create a new image containing only that layer.
|
|
</thetip>
|

</tip>
|
|
<tip level="intermediate">
|
|
<thetip>
|
|
A floating selection must be anchored to a new layer or to the last
|
|
active layer before doing other operations on the image. Click on the
|
|
"New Layer" or the "Anchor Layer" button in the
|
|
Layers dialog, or use the menus to do the same.

GIMP supports gzip compression on the fly. Just add <tt>.gz</tt>
|
|
(or <tt>.bz2</tt>, if you have bzip2 installed) to the filename and
|
|
your image will be saved compressed. Of course loading compressed
|
|
images works too.

|
Pressing and holding the <tt>Shift</tt> key before making a selection
|
|
allows you to add to the current selection instead of replacing it.
|
|
Using <tt>Ctrl</tt> before making a selection subtracts from the
|
|
current one.

<tip level="intermediate" help="gimp-selection-stroke">
|
|
<thetip>
|
|
You can draw simple squares or circles using Edit→Stroke Selection.
|
|
It strokes the edge of your current selection. More complex shapes
|
|
can be drawn using the Path tool or with Filters→Render→Gfig.
|
|
</thetip>
|

</tip>
|
|
<tip level="intermediate" help="gimp-path-stroke">
|
|
<thetip>
|
|
If you stroke a path (Edit→Stroke Path), the paint tools can
|
|
be used with their current settings. You can use the Paintbrush in
|
|
gradient mode or even the Eraser or the Smudge tool.

<tip level="intermediate" help="gimp-using-paths">

You can create and edit complex selections using the Path tool.

The Paths dialog allows you to work on multiple paths and to convert

them to selections.

You can use the paint tools to change the selection. Click on the

"Quick Mask" button at the bottom left of an image window.

Change your selection by painting in the image and click on the button
|

again to convert it back to a normal selection.

You can save a selection to a channel (Select→Save to Channel) and
|

then modify this channel with any paint tools. Using the buttons in
|
|
the Channels dialog, you can toggle the visibility of this new channel
|
|
or convert it to a selection.
