OpenTibia OTClient that unpack map.otbm to .png files - v4.0

[Stanos]

RL map has around 1.000.000 images and it takes around 50 GB before compression. After compression it's 10-15 GB.

Is there an option to compress specific folders more effectively? For instance, using PNG files instead of loading the 'minimap.otbm' generated by OTBM would make it look cleaner for OTC. Considering using, let's say, 'folder 14,' which represents zoom level 14. This could provide sufficient detail for the minimap to appear decent. However, implementing this feature in the client might be challenging due to the folder containing 14,000 images and files totaling 300MB

the .webp format works wonders

Adding 300 MB or even 50 MB to client, just to make minimap looks better in client seems to be a bad idea.
I would put it on webserver and in client Minimap module add button to open current minimap location in web browser.

the .webp format works wonders

WebP size is almost the same as JPEG. WebP colors are better and there are less artifacts.

80% quality:

If we drop quality to some very low number like 40%, there is a big difference in artifacts [check grass]:

100% quality for comparison:

If you want to compress to WebP, edit file website_and_php_files/4_compress.php ( otclient_mapgen/website_and_php_files/4_compress.php at master · gesior/otclient_mapgen (https://github.com/gesior/otclient_mapgen/blob/master/website_and_php_files/4_compress.php) )
replace:

$toExtension = '.jpg';

with:

$toExtension = '.webp';

and:

@imagejpeg($image, $savePath, $quality);

with:

@imagewebp($image, $savePath, $quality);

and in website_and_php_files/map_viewer/map.js ( otclient_mapgen/website_and_php_files/map_viewer/map.js at master · gesior/otclient_mapgen (https://github.com/gesior/otclient_mapgen/blob/master/website_and_php_files/map_viewer/map.js) )
replace:

imagesExtension: '.jpg',

with:

imagesExtension: '.webp',

Anyway, I would get free machine with 200 GB disk ( How to get FREE VPS from Oracle Cloud (https://otland.net/threads/how-to-get-free-vps-from-oracle-cloud.279318/) ) and upload .png images

Incorporating a minimap on the webserver and creating a module that directly links to a webserver for a game seems like a design flaw. It significantly increases the time players spend searching for in-game elements and lacks user convenience, but it just for me tho. Maybe im wrong

Yes. Best option would be to recreate "leaflet maps" in client Lua/OTUI and download images from web server in real time, but it would be a lot of work.

Is there any configuration to disable that hard check on Tibia.dat and Tibia.spr? My Otclientv8 shows that there is something wrong with Tibia.dat but it runs anyway and works well. Unfortunately mapgen cannot open properly and I had to use original tibia 10.98 dat to mimic my custom .dat.

You need to enable gd module in PHP.

WOW Thankks !! Worked perfectly !

 

[Struvim]

Insane! Good Work!

Are images created only in folder 16?
Zoom only works on 16+.
The map goes completely dark when it is at 15-
[Solved]
I did all the steps again and it worked.

Thanks for feature

Hey Gesior! Thanks for this tutorial. It's helped me a lot. You're the best!

Gesior, do you have 'update.php' for the streamUpdateURL?

I don't have that file.

Has anyone ever made it work using SRV item?
