GIMP (GNU Image Manipulation Program - Application de manipulation d'images du projet GNU)

GIMP (The GNU™ Image Manipulation Program) is a free raster graphics editor licensed under the GPL. It is primarily used as an image retouching and editing tool. GIMP is built upon the GTK+™ framework and can run on a variety of platforms. It is used for graphics editing tasks such as photo editing, image composition, and image creation.

GIMP can be enhanced by the use of plugins and scripts that perform complex operations. It can also be used to convert different image formats.

Some of the features and capabilities offered by GIMP include:

  • Une suite complète d'outils de peinture, y compris les brosses, un crayon, un aérographe, un outil clonage, un outil de correction, les fonctions Dodge et Burn et plus encore.

  • Prise en charge complète du canal alpha pour travailler avec la transparence.

  • Calques et canaux.

  • Fonctionnalités avancées de scripting.

  • Annuler/rétablir multiple (limité uniquement par l'espace disponible sur le disque)

  • Outils de transformation, incluant rotation, redimensionnement, rognage et retournement.

  • Support for a wide range of file formats, including BMP, GIF, JPEG, MPEG, PCX, PDF, PNG, PS, TGA, TIFF, XPM, and many others.

  • Les outils de sélection, tels que sélection rectangle, ellipse, libre, flou, bézier et des ciseaux intelligents.

  • Greffons pour ajouter de nouveaux formats de fichier et filtres d'effet.

Edition graphique dans GIMP

For editing images, you can use GIMP, a powerful and feature-packed application similar to Adobe™'s Photoshop. Here's how to edit graphics in GIMP:

  1. Install GIMP from the Muon package manager, which can be started by going to K menuComputerMuon Software Center.

  2. To run GIMP, go to K menuApplicationsGraphicsImage Editor (Gimp).

  3. In GIMP, go to FileOpen, navigate to the folder where the image is stored, and open it.

    Example 1. Ouvrir une image dans GIMP




  4. There are several tools available in GIMP for editing images, such as the 'Brush' and the 'Eraser' tools.

  5. When the editing is complete, go to FileSave to save your file, or use Save As to avoid overwriting the original image.

Création d'images

Creating graphics can easily be accomplished in GIMP. There are many filters and tools available that can be used to create stunning graphics. Here's how to create graphics:

  1. To create images/graphics, start with an empty image in GIMP. To do this, go to FileNew and enter the dimensions of the new image. Press OK.

    Example 2. Création d'une nouvelle image dans GIMP




  2. With an empty image, any of the numerous tools available in GIMP can be used to create a masterpiece! For example, use the text tool, marked with an 'A' in the toolbox window, to add some text to the image. The text can then be manipulated by using filters and adding more color to it.

    Example 3. Ajouter du texte à l'image




  3. When the image has been created, it can be saved. To save a file in GIMP, go to FileSave and choose a location where the file will be saved. GIMP requires that a file type be selected for the image being saved (PNG, JPG, etc.), so the file extension must be specified. The .xcf choice is considered to be the default extension for GIMP. It is the preferred file type that maintains the edit history of the image, which is helpful if the file is expected to be edited further in GIMP.

    Example 4. Enregistrer l'image
