Hello List - I recently downloaded the GIMP2.6 and have been playing =

play with the outcome. Kind of like Mr. Potato Head (hopefully you =
know what that is) , I am trying to take a part of one picture, say =
the nose, and transpose it to another picture; or perhaps the lips, =
eyes, etc. Once I have one aspect copied on the other picture I get =
stuck making it happen, both in context and melding of image sizes and =
a =E2=80=9Cseamless=E2=80=9D transition. Could you refer me to the rig=
ht tutorial, or =
provide me a facile method to perform this feature using GIMP? Also, =
how do you rectify the image size so that if the pictures are of =
different sizes the transposed part looks of appropriate dimension to =
the host picture.
I very much appreciate your time and any input you might afford me.
The right way to do it is to keep all the added bits in their own layer =
until the end. Layers can be moved, scaled and rotated around with the =
move, scale and rotate tools in the tools palette. You can combine move =
and scale quite seamlessly (but if anyone knows how to rotate at the =
same time, I'll be glad to hear it).
Seamless transition between layers is achieved by gradual transparency =
on the edges. The easy way to achieve it is to "feather" the selection =
on a couple of pixels when you copy/paste. A more complete way is to use =
layer masks that give you full control of the amount of transparency of =
all pixels in a layer. Basicall you add a mask to the layer in the =
layers dialog and click on it to make the editable thing. Wherever you =
apply black the layer image is transparent and where it's white the =
layer is opaque. You can of course use various levels of grey... so you =
can literally paint transparency.
