## Chapitre 6. Enregistrer les images avec GIMP

## 1. Fichiers

GIMP is capable of reading and writing a large variety of graphics file formats. With the exception of GIMP's native XCF file format, file handling is done by plug-ins. This makes it relatively easy to extend GIMP to support new file types when the need arises.

### 1.1. Enregistrer / Exporter des images

| Note
When you open an image, let's say in JPG or PNG file format, it is imported into GIMP's own XCF format, as a new project. For example, a « sunflower.png » image will be loaded as « *[sunflower] (imported)-1.0 (indexed color, 1 layer) ». The leading asterisk indicates that this file has been changed. This image can be saved as « sunflower.xcf » by using the Save command. If you need your image in another format, you should use the Export command.

When you are finished working with an image, you will save the results. In fact, it is often a good idea to save at intermediate stages too. GIMP is a pretty robust program, but on rare occasions crashes have happened.

GIMP's native format XCF is special. It is the only format that can store everything about an image (with the exception of « undo » information). This is the reason that saving can only be done in this format. It makes the XCF format especially suited for storing intermediate results, and for saving images to be re-opened later in GIMP.

XCF files are not readable by most other programs that display images. Once you have finished editing your image, you can export it to the format of your choice. GIMP supports a wide range of formats. Most file formats that can be imported, can also be used for exporting.

### 1.2. Formats de fichiers

There are several commands for saving and exporting images. They are listed in the section covering the File Menu. More information on how to use them can be found there.

GIMP permet d’exporter les images crées dans un grand nombre de formats variés. Il est important de comprendre que le seul format capable d’enregistrer toutes les informations sur une image y compris les calques, la transparence, etc…, est le format natif XCF de GIMP. Chacun des autres formats conserve certaines propriétés et perdent les autres. C’est à vous de comprendre les possibilités du format choisi.

L’exportation ne modifie pas l’image présente sur votre écran et n’entraîne aucune perte d’information. Voyez Exporter des fichiers.

| Note
When you close an image (possibly by quitting GIMP), you are warned if the image has been changed without subsequently being saved (an asterisk is in front of the image name in the title bar of the main window).
