[英]FontMetrics returning wrong character size
since I work on a LWJGL project, it encountered a problem to display text. 由于我从事LWJGL项目,因此在显示文本时遇到了问题。 In theory I'd like to iterate through the (extended) ascii table and save each texture of all the chars inside of a ArrayList.
从理论上讲,我想遍历(扩展的)ascii表并将所有char的每个纹理保存在ArrayList中。
But my problem is that it won't get the right dimensions while creating a char image. 但是我的问题是,在创建char图像时,它将无法获得正确的尺寸。 The dimensions seem to be 1 (width) x 3 (height) Code:
尺寸似乎是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;
}
May anyone help me out there please? 有人可以帮我吗? Or if you have another idea to fix this, just let me know
或者,如果您有其他解决办法,请告诉我
The line font.awtFont.deriveFont(100);
行
font.awtFont.deriveFont(100);
in your code currently literally does nothing except waste time by creating a new font and then immediately discarding it and using the original font instead. 在您的代码中,当前实际上不做任何事情,只是浪费时间,方法是创建一个新字体,然后立即将其丢弃并改用原始字体。
Derive the new font and then use it: 派生新字体 ,然后使用它:
....
Font bloodyHuge = font.awtFont.deriveFont(100);
graphics.setFont(bloodyHuge);
...
