Resynthesizer tutorial

Download and unzip the zip archive for Windows or the tar.gz file.
The readme file contains a description of controls, but too short, hence this tutorial.

Installing on Linux

Copy all the files into:

~/.gimp-2.8/plug-ins/

Installing on Windows:

For the version 2, rebuild the binaries with a C++ compiler.

Copy the files into:

c:\Users\username\gimp-2.8\plug-ins\  

If you can not compile the plugin, you can use the previous version that comes with an installer. Download and extract the archive, run the executable and replace 2.6 by 2.8 in the suggested path.

Commands for using resynthesizer

A new command appears in the menu "Script-fu": Enhance.
It contains three lines:

Smart enlarge

Creates a new image from the selection.

Smart remove selection

Deletes an object framed by the tool selection and restores the background.
You can not select the sample, so it is better to use the filter described below.

Deletes an object framed by the tool selection and restores the background based on what surrounds the object. We define the length of the radius.
We can not select the sample, so it is better to use the filter described below.
On Windows, the script has a bug and takes the top left corner of the image rather than what is around. There is a patch on Gimp.org.

Smart sharpen

Makes the image cleaner.

To use the Resynthesizer, you select a portion of the image, then click on one of these three options.

The resynthesizer filter

It is located in the menu:

Filter -> Map ->  Resynthesize...

The filter can create a texture, usable as a tile or delete an object as does the command "smart remove selection".
But it also allows to select the sample.

Options:

Horizontal / Vertical tilable

Allows to change the image into a tile usable as a texture.
Uncheck if you want to delete an object in the image instead.

Fit output to bordering pixels

The object to delete being defined by a selection, the plugin will ensure that the edge of the texture fit what is around

Texture transfer

Allows you to specify two images that will guide the placement of the texture in the final image.
The plugin will search in the source texture pixels having similar colors in the input image and the output image.
The input image must have the same mode and same size as the image used as texture (Texture source).
The output image must have the same method and same size as the image to change, the current image. We use mostly the current image itself.

Map importance

The slider determines the importance with which must be taken into account these two transfer images (maps).

Sensitivity to outliers

Define a sensitivity. You may want to erase the differences or take them into account.

Now we will enter into practice, step by step, with images obtained at each step.
