TextDraw Anti-Aliasing Fix

TextDrawAntiAliasingFix.asi is a GTA San Andreas plugin that supersamples the SA-MP model preview textdraws.

SA-MP renders preview models into a small off-screen texture that driver anti-aliasing never reaches, so vehicle and skin previews stay jagged while the scene behind them is smooth. The plugin renders that pass at a multiple of the preview's resolution and scales it back down, and can enlarge the preview texture itself. The framing the server asked for is unchanged.

Features

• 2x, 4x or 8x supersampling of the model preview.
• Optional 2x, 4x or 8x enlargement of the 256x256 preview texture.
• Falls back to a lower factor when video memory runs out.
• Verifies the bytes it replaces before writing and refuses to patch any other executable.

Requirements

• GTA San Andreas 1.0 US (Compact or Hoodlum executable).
• An ASI loader, such as Silent's ASI Loader or Ultimate ASI Loader.
• SA-MP. Verified against the 0.3.7-R1 client; other builds are expected to work but were not inspected.
• A Direct3D 9 device with enough video memory for a render target of previewScale * supersample * 256 pixels a side.

Other executables are left untouched.

Installation

1. Extract TextDrawAntiAliasingFix.asi and TextDrawAntiAliasingFix.ini into the GTA San Andreas directory or its scripts directory.
2. Start the game and connect to a server that uses preview-model textdraws.

Configuration

TextDrawAntiAliasingFix.ini next to the plugin, created with these defaults when it is missing:

Settings are read once when the game starts. The two multipliers compound: the defaults render at 2048x2048 for a 512x512 preview texture.
