Il y a quelques jours, je l'ai fait une visière ArcGISCache avec OpenLayers 2.12 avec quelques tuiles dans ce dossier et le format de fichier:OpenLayers 3 ArcGIS Cache Server fichiers locaux
_alllayers \ L04 \ R00000009 \ C00000a07.png
Cela signifie que mes mosaïques se trouvent dans le dossier "_alllayers", puis dans d'autres dossiers indiquant le niveau de zoom (L00, L01 ... L21). A l'intérieur d'eux j'ai d'autres dossiers avec leur nom comme: "R00000009" et puis à l'intérieur de ces dossiers, j'ai les images nommées comme: "C00000a07.png".
Quand je l'ai fait la visière pour OpenLayers 2.12 ou OpenLayers 2.14 je l'ai fait bien et fonctionne bien. Mais quand j'ai essayé de faire la même chose avec OpenLayers 3, cela ne fonctionne pas.

Comme je l'ai dit, cela fonctionne très bien. Mais quand j'essaye de faire la même chose à OpenLayers 3, je ne peux pas. Je ne sais pas pourquoi demander les images comme s'il y avait un service.

Lorsque je tente de charger cette OpenLayers 3 pare-soleil, je peux voir dans la console une erreur 404, ce qui est le type d'URL qu'il essaie de trouver:
http://MY_IP:MY_PORT/MY_FOLDER/Layers/_alllayers/?F=image&FORMAT=PNG32&TRANSPARENT=true&SIZE=256%2C256&BBOX=-20037508.342789244%2C0%2C0%2C20037508.342789244&BBOXSR=3857&IMAGESR=3857&DPI=90
Pretty Print
http://MY_IP:MY_PORT/MY_FOLDER/Layers/_alllayers/?F=image
&FORMAT=PNG32
&TRANSPARENT=true
&SIZE=256%2C256
&BBOX=-20037508.342789244%2C0%2C0%2C20037508.342789244
&BBOXSR=3857
&IMAGESR=3857
&DPI=90
Alors, mes questions sont les suivantes:
- Pourquoi OpenLayers 3 demande pour les images (tuiles) comme il était un service derrière?
- Hoy puis-je utiliser mes carreaux dans OpenLayers 3?
J'ai essayé de changer l'URL avec ce modèles:
http://MY_IP:MY_PORT/MY_FOLDER/Layers/_alllayers/ImageServer
http://MY_IP:MY_PORT/MY_FOLDER/Layers/_alllayers/ImageServer/export
http://MY_IP:MY_PORT/MY_FOLDER/Layers/_alllayers/Tiles/{z}/{x}/{y}
Edit:
Enfin j'ai résolu! J'ai fait en Java un programme qui convertit tous ces dossiers et noms d'images. J'essayais de comprendre le modèle que les noms de dossiers et d'images ont, et finalement je me suis rendu compte que la première lettre des dossiers signifiait les rangées (R -> rangée) et la première lettre des images signifiait des colonnes (C -> colonne).
Une fois que vous avez supprimé la première lettre, juste besoin de convertir ce nombre hexadécimal en décimal et enregistrer le fichier ou le dossier avec ce nouveau nom.
Si quelqu'un a besoin d'aide, je serai ravi de vous aider.
