rounded corners on jpg image.
Quoting "John R. Culleton" :
have a jpg image that is in rectangular form. I would like to
round the corners off symmetrically to soften the shape a bit.
Which is the quickest way to to this?
The quickest way is to:
* Select all
* Perform a "Rounded rectangle" (I think you will find this on the
"Select" menu, but on previous GIMP versions it may be under
"Script-fu->Selection")
* Invert the selection
* Fill with a background color (JPEGs do not support transparent
areas, therefore you have to choose a specific color for the corners)
If you would prefer to have the corners match the background of
whereever the image is to appear (on a webpage, for example), you will
have to use the PNG format (GIFs will work, too; but will have "ugly"
edges). Change the last step above to:
* Perform a "Layer->Transparency->Add alpha channel" and then an "Edit->Clear"
If you *have* to use JPEG format, I would recommend that you place a
border around your image:
* Select all
* Perform a "Rounded rectangle" (I think you will find this on the
"Select" menu, but on previous GIMP versions it may be under
"Script-fu->Selection")
* Create a new transparent layer. Increase this layer's boundary size
by the amount of border you think will look good. Use the "Center"
option when resizing the layer
* Perform an "Image->Fit canvas to layers"
* Invert the selection
* Fill with a border color
