AffTools

A toolset for Arcaea aff files.

• Aff2Preview: 2D chart preview generator

Aff2Preview

Generate 2D chart preview image by aff file.

Use System.Drawing.Common to generate image. However, you can override AffTools.MyGraphics.GraphicsAdapter to use your own image library.

Usage:

using AffTools.Aff2Preview;

AffRenderer affRenderer = new("assets/2.aff")
{
    Title = "Gift",
    Artist = "Notorious(Nota & TRIAL)",
    Charter = "Misaka12456",
    Side = 0,  // 0:hikari  1:tairitsu  2:dynamix or tempestissimo
    Difficulty = 2,
    Rating = 10.3f,
    Notes = 0, // notes are counted by internal note counter now
    ChartBpm = 200,
    IsMirror = false, // controls whether the chart is mirrored or not
};

// image resource to generate chart preview.
// for each side, please specify the image manually.
affRenderer.LoadResource(
    "assets/note.png",
    "assets/note_hold.png",
    "assets/arc_body.png",
    "assets/base.jpg",  // empty string if unwanted
    "assets/base.jpg"); // empty string if unwanted

var image = affRenderer.Draw();

image?.SaveToPng("output.png");

Example output: assets/2.aff
