因为我在LWJGL项目中工作,所以它在显示文本时遇到了问题。理论上,我想遍历(扩展的) ascii表,并将所有字符的每个纹理保存到一个ArrayList中。
但我的问题是,在创建字符图像时,它不会获得正确的尺寸。尺寸看起来是1(宽)x 3(高)代码:
private static BufferedImage createCharImage(Font font, char c) {
BufferedImage image = new BufferedImage(100, 100, BufferedImage.TYPE_INT_ARGB);
Graphics2D graphics = image.createGraphics();
// As you see, I set the font size to 100 for testing
font.awtFont.deriveFont(100);
graphics.setFont(font.awtFont);
FontMetrics fontMetrics = graphics.getFontMetrics();
graphics.dispose();
// Here the problem appears that the dimensions seem to be w: 1 and h: 3
Vector2i charDimensions = new Vector2i(fontMetrics.charWidth(c), fontMetrics.getHeight());
if (charDimensions.x == 0) {
return null;
}
image = new BufferedImage(charDimensions.x, charDimensions.y, BufferedImage.TYPE_INT_ARGB);
graphics = image.createGraphics();
graphics.setFont(font.awtFont);
graphics.setPaint(java.awt.Color.WHITE);
graphics.drawString(String.valueOf(c), 0, fontMetrics.getAscent());
graphics.dispose();
return image;
}有谁能帮帮我吗?或者,如果你有其他想法来解决这个问题,请让我知道

从字面上看,代码中的font.awtFont.deriveFont(100);行除了浪费时间之外什么也不做,它创建了一个新字体,然后立即丢弃它,并使用原来的字体。
Derive the new font,然后使用它:
....
Font bloodyHuge = font.awtFont.deriveFont(100);
graphics.setFont(bloodyHuge);
