示例1: cacheVector
import java.awt.font.GlyphVector; //导入方法依赖的package包/类
private Rectangle cacheVector(GlyphVector vector) {
/*
* Compute the exact area that the rendered string will take up in the image buffer. Note that
* the string will actually be drawn at a positive (x,y) offset from (0,0) to leave enough room
* for the ascent above the baseline and to correct for a few glyphs that appear to have negative
* horizontal bearing (e.g. U+0423 Cyrillic uppercase letter U on Windows 7).
*/
final Rectangle vectorBounds = vector.getPixelBounds(fontContext, 0, 0);
/* Enlage the stringImage if it is too small to store the entire rendered string */
if (vectorBounds.width > stringImage.getWidth() || vectorBounds.height > stringImage.getHeight())
allocateStringImage(Math.max(vectorBounds.width, stringImage.getWidth()),
Math.max(vectorBounds.height, stringImage.getHeight()));
/* Erase the upper-left corner where the string will get drawn*/
stringGraphics.clearRect(0, 0, vectorBounds.width, vectorBounds.height);
/* Draw string with opaque white color and baseline adjustment so the upper-left corner of the image is at (0,0) */
stringGraphics.drawGlyphVector(vector, -vectorBounds.x, -vectorBounds.y);
return vectorBounds;
