GBX.NET.Imaging

Provides extensions for image handling in GBX.NET (GDI+, Windows only).

Exporting WEBP icons with correct rotation (TM2020 April 2022 update) is not supported, use GBX.NET.Imaging.SkiaSharp or GBX.NET.Imaging.ImageSharp instead for this purpose.

Framework support

• .NET 8 (Windows)
• .NET 6 (Windows)
• .NET Standard 2.0

Usage

Export thumbnail from map

You can use CGameCtnChallenge.Thumbnail to get the pure JPEG bytes, but the thumbnail is going to be upside down. This is a long-standing bug in Nadeo games. ExportThumbnail method flips this thumbnail correctly.

using GBX.NET;
using GBX.NET.Engines.Game;
using GBX.NET.Imaging; // You need to add this

var map = Gbx.ParseHeaderNode<CGameCtnChallenge>("Path/To/My.Map.Gbx");

map.ExportThumbnail("MyThumbnail.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);

Quality could be degraded as the thumbnail. Use the format parameter to tweak the quality.

Export icon from any CGameCtnCollector (before TM2020 April 2022)

This includes any Item.Gbx, Block.Gbx, Macroblock.Gbx, EDClassic.Gbx, Collection.Gbx, and many more...

using GBX.NET;
using GBX.NET.Engines.GameData; // Note it's GameData now instead of Game
using GBX.NET.Imaging; // You need to add this

var node = Gbx.ParseHeaderNode("Path/To/My.Item.Gbx");

if (node is CGameCtnCollector collector)
{
    collector.ExportIcon("MyIcon.png");
}

Quality should not be degraded as the icon is processed with pure color bytes and exported to PNG as default. Use the format parameter to tweak the exported format.
