Apply Curve Bend Effect to Images in the GIMP Application
Edited by Freya, VisiHow, Eng
You're watching VisiHow. In this tutorial, we're going to show you how to apply a "Curve Bend" filter to an image in GIMP in Windows 7.
First, click "Filters".
It is in the horizontal menu at the top of the screen.
Move the cursor to "Distorts" in the menu.
In the expanded menu, click "Curve Bend...".
It is the third option on the list. A dialogue box will appear, where you should see a preview on the left side.
You can click "Preview Once".
Alternatively, check the "Automatic preview" box.
It is recommended to select "Automatic preview" so that you can see how your changes affect the shape of the image.
Next, you can modify the curve by clicking within the graph-like area.
Clicking the curve on the graph allows you to add multiple anchor points.
Then, you can click and drag them.
You can click adjust the "Rotate" value.
You can check or uncheck "Smoothing" and "Antialiasing".
These are in the lower-left corner of the dialogue box.
You can also check "Work on copy".
It is recommended to use this if you don't have a copy of the layer to refer back to as you make your changes.
You can also click either "Upper" or "Lower" under "Curve for Border".
This is underneath the graph area. This option will place the curve on either the upper or lower part of the image.
Then, you can click either "Smooth" or "Free" in "Curve Type".
"Free" looks much more organic, but you may work with "Smooth" more when using this filter.
Finally, you can click "Copy", "Mirror", "Swap", and "Reset".
These control the curve.
Once you're satisfied with the changes, click "OK" to apply them to the image.
