you can step from point to point,
and make other points to the curremt point.
"Clear Point"
does reset Witdh, Height and Opacity of the point to 100%
and Rotat to 0 degree.
"Clear Point" "Clear All Points"
does reset Width, Height and Opacity of the point to 100%
and Rotation to 0 degree, and leaves the path (X/Y Values)
unchanged.
"Reset Points"
"Delete All Points"
removes all controlpoints.
"Rotate Follow"
Calculate Rotate values for all controlpoints
to follow the path.
An Object moving along a horizontal line
from left to right results in an angle of 0 degree.
(or a multiple of 360 degress if the path
builds circular loops)
A vertical Move from top to bottom gives 90 degrees.
SHIFT: If this Button is clicked while the
Shift Key is pressed, a fix Rotation offset
is added to all the calculated Rotation Values.
The Rotation Offset is taken from the current
Rotate Value of Controlpint 1.
If an Object moves from Right to Left
the calculated Angle is 180 degree and the Object
appears upside down.
With a Startoffset of 180 (or -180)
you can compensate this effect.
"Save Points"
saves your controlpoints to file

Welcome to the GIMP !
Nearly all image operations are performed by right-clicking
on the image. And don't worry, you can undo most mistakes...
# Tips for beginners start here

You can get context-sensitive help for most of the GIMP's features by
pressing the F1 key at any time. This also works inside the menus.
The 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.
You can perform many layer operations by right-clicking on the text
label of a layer in the Layers dialog (Dialogs->Layers & Channels).
label of a layer in the "Layers, Channels and Paths" dialog
When trying to save files as GIF, XPM, or any other indexed
color format, you need to convert the image to indexed using
the Image menu.
When you save an image to work on it again later, try using XCF,
the GIMP's native file format (use the file extension ".xcf").
This preserves the layers and every aspect of your work-in-progress.
Once a project is completed, you can save it as JPEG, PNG, GIF, ...
You can get the Tool Options menu to open by double-clicking
any button in the toolbar.
You can change the name of a layer by double-clicking
on its name in the Layers dialog box.
The layer named "Background" is special. You can't add
transparency or a layer mask to it. To add transparency, you
must first "add alpha" to the layer by right-clicking in the
layers dialog and selecting "Add Alpha Channel".
When using a drawing tool (Paintbrush, Airbrush, or Pencil),
Shift-click will draw a straight line from your last drawing
point to your current cursor position.
The layer named "Background" it special because it lacks transparency.
This prevents you from adding a layer mask or moving the layer up in
the stack. You may add transparency to it by right-clicking in the
"Layers, Channels and Paths" dialog and selecting "Add Alpha Channel".
Most plug-ins work on the current layer of the current image. In
some cases, you will have to merge all layers (Layers->Flatten Image)
if you want the plug-in to work on the whole image.
Most file-formats can't handle layers and for that reason only
the active layer is saved. Use XCF, the GIMP's native file format
to keep layers, channels and guides when saving.
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 to RGB, add an alpha-channel or flatten it.

You can drag and drop many things in the GIMP. For example, dragging
a color from the toolbox or from a color palette and dropping it into
an image will fill the current image or selection with that color.
When using a drawing tool (Paintbrush, Airbrush, or Pencil),
Shift-click will draw a straight line from your last drawing
point to your current cursor position. If you also press Ctrl,
the line will be constrained to 15 degree angles.
The file selection dialog box has command-line completion with
Tab, just like the shell. Type part of a filename, hit tab, and voila!
It's completed.

selecting a menu item, and pressing the new shortcut key combination.
This is dynamic and is saved when you exit GIMP.
All the old channel operations have been replaced with the more
powerful and flexible Layer and Layer Mode operations. They may
take getting used to, but they are simply a better way to operate.
You can use the middle mouse button to pan around
the image, if it's larger than its display window.
@ -91,8 +88,17 @@ 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.
You can drag a layer from the "Layers, Channels and Paths" dialog
and drop it onto the toolbox. This will create a new image
containing only that layer.
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 Anchor Layer buttons in the "Layers, Channels and Paths"
dialog, or use the menus to do the same.
The GIMP supports gzip compression on the fly. Just add
'.gz' (or '.bz2', if you have bzip2 installed) to the filename
".gz" (or ".bz2", if you have bzip2 installed) to the filename
and your image will be saved compressed. Of course loading
compressed images works too.

making a selection in order to constrain it to a perfect square
or circle, or to have it centered on its starting point.
Using Edit->Stroke allows you to draw simple squares or circles by
painting the edge of your current selection with the active brush.
More complex shapes can be drawn with Filters->Render->Gfig.
If you stroke a path (Edit->Stroke), the current drawing tool and its
settings are used. You can use the Paintbrush in gradient mode, the
Clone tool with a pattern or even the Eraser or the Smudge tool.
You can create and edit complex selections using the Bezier tool.
The "Paths" tab in the "Layers, Channels and 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" tab of the "Layers, Channels and Paths" dialog, you can
toggle the visibility of this new channel or convert it to a selection.

When installing a new version, be sure to delete your personal GIMP

TrueType (.ttf) fonts, which are also scalable.
To create a perfect circle, hold Shift while doing an ellipse select. To
place a circle precisely, drag horizontal and vertical guides tangent to
the circle you want to select, place your cursor at the intersection
of the guides, and the resulting selection will just touch the guides.
If some of your scanned photos do not look colorful enough, you can
easily improve their tonal range with the "Auto" button in the Levels
tool (Image->Colors->Levels). If there are any color casts, you can
correct them with the Curves tool (Image->Colors->Curves).
