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.SkiaSharp; // You need to add this

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

map.ExportThumbnail("MyThumbnail.jpg", SkiaSharp.SKEncodedImageFormat.Jpeg, quality: 95);

Export icon from any CGameCtnCollector

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

For TM2020 after April 2022 update, the WEBP icon is also rotated correctly.

using GBX.NET;
using GBX.NET.Engines.GameData; // Note it's GameData now instead of Game
using GBX.NET.Imaging.SkiaSharp; // 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 either pure color bytes or lossless WEBP and exported to PNG as default. Use the format and quality parameters to tweak the exported format.
