由于我从事 LWJGL 项目,因此遇到了显示文本的问题。理论上,我想遍历(扩展)ascii 表并将所有字符的每个纹理保存在 ArrayList 中。
但我的问题是它在创建 char 图像时无法获得正确的尺寸。尺寸似乎是 1(宽度)x 3(高度)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;
}
有人可以帮我吗?或者,如果您有其他想法来解决此问题,请告诉我
