Tools > Create Font unable to disable smoothing on macOS

Created by: kylemcdonald

Description

When using createFont() or the Create Font tool to create a PFont for a bitmap pixel font with smoothing disabled, there are still grays in the generated font.

Expected Behavior

Created by thresholding the result in Photoshop:

Current Behavior

Generated directly by Processing:

Steps to Reproduce

Here is a link to the font I am using: sg08.zip

PFont font;

void setup() {
  size(512, 512);
  font = createFont("SHAKAGRAPHICS08", 8, false);
  noSmooth();
  textFont(font, 8);
  textAlign(LEFT, TOP);
}

void draw() {
  background(255);
  fill(0);
  noStroke();
  String str = "Forsaking monastic tradition,\ntwelve jovial friars gave up\ntheir vocation for a questionable\nexistence on the flying trapeze.";
  text(str, 20, 20);
}

Your Environment

• Processing version: 4.0b1
• Operating System and OS version: MacOS 11.6

Possible Causes / Solutions

I did some basic checks to see that this is happening at font generation time, and not in the rendering. I don't know the Processing internals enough to advise beyond this. Last time I tried this font was circa 2011 and I know it worked correctly Processing back then :)

提供された sg08.zip フォントと createFont("SHAKAGRAPHICS08", 8, false) を使用するスケッチで、macOS 上の問題を再現します。Create Font ツールと createFont() のフォント生成パスを追跡し、どこでスムージングが導入されるのかを特定します。スムージングを無効にしたときに、生成されたビットマップフォントに意図しないグレーのピクセルがなく、通常のフォント動作に影響がないことを確認できれば完了です。
