Bukkit

Have you ever wanted to view an image on a map ingame? ImageOnMap allows you to do it! (Inspired by ImgMap)

Features

ImageOnMap allows you to load a picture from the Internet to a Minecraft map.

• Loads an image from a URL onto a map. PNG, JPEG and GIF are supported.
• These images will be saved on your server and reloaded at restart.
• Big pictures will be cut automatically into several parts! As example, a 1024x1024 picture will be cut in 16 maps.
• Your image will be centered.
• You can put your map in an item frame.

This plugin is a free software lisensed under the GNU General Public License (version 3 or above). The source code is published on GitHub.

The latest version is only compatible with Minecraft 1.15+.

• For Minecraft 1.13 and 1.14, use 4.0-pre1.
• For older versions, please use ImageOnMap 3.1 (warning: unchecked by the BukkitDev staff—if you're unsure, use 3.0 here in BukkitDev, it's the same but without permissions).

Support and bug requests

If you need help with ImageOnMap, the preferred way is our Discord server. We speak English and French. You should read the FAQ first!

If you want to report a bug or suggest features, by far the best option for us is GitHub issues, which you should use whenever possible. If you absolutely can't use GitHub, use the support options above.

We're a team behind ImageOnMap (and others), and private messages from Spigot can only be read by one person. So you should not send help requests, suggestions or bug reports using Spigot or BukkitDev PMs. Any PM received after June 28, 2020 with any of these topics will be ignored.

Quick guide

1. Ensure that you have a free slot in your inventory, as ImageOnMap will give you a map.
2. Type /tomap URL, where URL is a link to the picture you want to render (see the section below).
3. Enjoy your picture! You can place it in an item frame to make a nice poster if you want.

Commands and Permissions

/tomap <url>

Renders an image and gives a map to the player with it.

• This command can only be used by a player.
• The link must be complete, do not forget that the chat limit is 240 characters.
• You can use an URL shortener like tinyURL or bitly.
• If you want a picture in one map, type resize after the link.
  • If you want to resize to multiple maps, add the witth and height after resize: e.g. /tomap url resize 2 4
  • You can change the scaling method by replacing the resize keyword in the /tomap command by:
    • resize-stretched to stretch the image to the surface (the image could be distorted); or
    • resize-covered to ensure the image covers the whole surface (the image will never be distorted, but some parts may be lost near the borders).
• Permission: imageonmap.new (or imageonmap.userender—legacy, but will be kept in the plugin).

/maps

Opens a GUI to see, retrieve and manage the user's maps.

• This command can only be used by a player.
• Opens a GUI listing all the maps in a paginated view.
• A book is displayed too to see some usage statistics (maps created, quotas).
• A user can retrieve a map by left-clicking it, or manage it by right-clicking.
• Maps can be renamed (for organization), deleted (but they won't render in-game anymore!), or partially retrieved (for posters maps containing more than one map).
• Permission: imageonmap.list, plus imageonmap.get, imageonmap.rename and imageonmap.delete for actions into the GUI.

/maptool <new|list|get|delete|explore|migrate>

Main command to manage the maps. The less used in everyday usage, too.

• The commands names are pretty obvious.
• /maptool new is an alias of /tomap.
• /maptool explore is an alias of /maps.
• /maptool migrate migrates the old maps when you upgrade from IoM <= 2.7 to IoM 3.0. You HAVE TO execute this command to retrieve all maps when you do such a migration.
• Permissions:
  • imageonmap.new for /maptool new;
  • imageonmap.list for both /maptool list and /maptool explore;
  • imageonmap.get for /maptool get;
  • imageonmap.delete for /maptool delete;
  • imageonmap.administrative for /maptool migrate.

About the permissions

All permissions are by default granted to everyone, with the exception of imageonmap.administrative. We believe that in most cases, servers administrators want to give the availability to create images on maps to every player.
Negate a permission using a plugin manager to remove it, if you want to restrict this possibility to a set of users.

You can grant imageonmap.* to users, as this permission is a shortcut for all user permissions (excluding imageonmap.administrative).

Changelog

3.0

The 3.0 release is a complete rewrite of the original ImageOnMap plugin, now based on zLib, which adds many features and fixes many bugs.

This new version is not compatible with the older ones, so your older maps will not be loaded. Run the/maptool migrate command (as op or in the console) in order to get them back in this new version.

You will find amongst the new features:

• New Splatter maps, making it easy to deploy and remove big posters in one click!
• No more item tags when maps are put in item frames!
• Internationalization support (only french and English are supported, for now; contributions are welcome)
• Map Quotas (for players and the whole server)
• A new map Manager (based on an inventory interface), to list, rename, get and delete your maps
• Improvements on the commands system (integrated help and autocompletion)
• Asynchronous maps rendering (your server won't freeze anymore when rendering big maps, and you can queue multiple map renderings !)
• UUID management (which requires to run /maptool migrate)

If you want to allow everything, remove the images-hostnames-whitelist list entirely, or empty it. There is also a permission to ignore the allow list: imageonmap.bypasswhitelist.
