Hello Amstrad community!

I won’t present you the Amstrad CPC, the 8-bit home computers produced by Amstrad between 1984 and early 1990s. You probably spent already thousands of hours enjoying a wide range of game software, and the bravest may have typed dozens of “DATA”-filled listing program pages, all by hand. Yes because at that time we did not have a mouse, and there was no such thing as “copy and paste”…

Amstrad CPC computer

You who have invested in computer programming for long months in the late 80s and early 90s know how limited machines were back then, and how you had to trick to gain space or speed. You may have started in BASIC to finally see its limits and move towards Assembly, Z80, or machine language programming.

The Amstrad CPC has 27 fixed colors. The BASIC language has 3 graphic modes:

MODE 0

16 colors

You certainly remember your floppy disks. You had to type "cat" to see its content, and sometimes in the files listed there was an “IMAGE.SCR” or “IMAGE.BIN” file (always 17k), which corresponded most of the time to an image displayed while a game was loading.

These 17k files were actually finary files representing the full screen memory of the Amstrad computer. This is the kind of image that will be possible to create with the ImgToCpc software, and then easily display it on your Amstrad CPC.

Convert an image to Amstrad format

Image-To-Amstrad-CPC (or “ImgToCpc”) is a image processing utility that makes it possible to convert your picture or image file directly to Amstrad floppy format, so that you will only have to type “run” to display your image on the CPC screen.

Image-To-Amstrad-CPC supports JPG, PNG, BMP, PCX, LBM, TGA image formats.

Image-To-Amstrad-CPC will directly create:

  • a preview image to check the results
  • the equivalent 17k image file in Amstrad binary format
  • a launch file that corresponds to the Basic commands to display the image on the screen
  • a floppy file (.DSK) containing the image, the launcher above and readable by an Amstrad CPC emulator such as WinAPE or CPCBox.

Bonjour Amstradiennes et Amstradiens !

Je ne vais pas vous présenter l’Amstrad CPC, l’ordinateur 8 bits d’Amstrad produit entre 1984 et le début des années 1990. Vous avez sûrement déjà passé des milliers d'heures à profiter d'une large gamme de jeux en disquettes (ou cassette pour les plus anciens). Les plus courageux ont peut-être tapé des dizaines de pages de programmes appelés "listing", remplis de DATA, tout ça à la main à une époque où il n’y avait pas de souris et où le copier-coller n’existait pas…

Vous qui vous êtes frotté à la programmation informatique à la fin des années 80 et début 90, vous savez combien les machines étaient limitées à l’époque, et qu’il fallait ruser pour gagner de la place ou de la rapidité d’exécution. Vous avez peut-être commencé en BASIC pour finalement constater ses limites et vous orienter vers la programmation en assembleur, Z80, ou langage machine.

Vous vous rappelez certainement de vos disquettes. Il fallait taper “cat” pour en voir la liste des fichiers, et parfois il y avait un fichier IMAGE.SCR ou IMAGE.BIN (toujours de 17k), ce qui correspondait à une image affichée le temps du chargement d’un jeu par exemple. Il s’agit en fait d’un fichier binaire représentant la mémoire de l’écran Amstrad. C’est ce type de fichier image qu’il va être possible de créer avec le logiciel ImgToCpc pour ensuite l’afficher simplement sur votre Amstrad CPC.

Convertir une image au format Amstrad

Image-To-Amstrad-CPC (ou “ImgToCpc”) est un utilitaire de traitement d’image qui vous permet de convertir votre fichier image ou photo directement ou format disquette Amstrad, de telle sorte que vous n’ayez qu’à taper “run” pour lancer l’affichage de votre image à l’écran du CPC.

Image-To-Amstrad-CPC prend en charge les images au format JPG, PNG, BMP, PCX, LBM, TGA.
Il va directement créer :
- une image de prévisualisation pour vérifier le résultat
- cette même image, au format image binaire Amstrad de 17k
- un fichier de lancement qui correspond aux instructions Basic pour afficher l’image à l’écran
- un fichier disquette (.DSK), lisible par un Émulateur Amstrad CPC comme par exemple WinAPE ou CPCBox.

Exemples d’images et résultats de conversion

- Pour vous rendre service, les exemples de code en Français sont aussi disponibles.
- Vous pouvez aussi consulter la page de Image-To-Amstrad-CPC en Français.
- Liste complète des options de conversion de Image-To-Amstrad-CPC.
