示例1: encode
import com.google.typography.font.sfntly.table.core.HorizontalDeviceMetricsTable; //导入方法依赖的package包/类
public WritableFontData encode(Font sourceFont) {
HorizontalDeviceMetricsTable hdmx = sourceFont.getTable(Tag.hdmx);
HorizontalMetricsTable hmtx = sourceFont.getTable(Tag.hmtx);
MaximumProfileTable maxp = sourceFont.getTable(Tag.maxp);
FontHeaderTable head = sourceFont.<FontHeaderTable>getTable(Tag.head);
int unitsPerEm = head.unitsPerEm();
int numRecords = hdmx.numRecords();
int numGlyphs = maxp.numGlyphs();
MagnitudeDependentWriter magWriter = new MagnitudeDependentWriter();
for (int i = 0; i < numRecords; i++) {
int ppem = hdmx.pixelSize(i);
for (int j = 0; j < numGlyphs; j++) {
int roundedTtAw =
((64 * ppem * hmtx.advanceWidth(j) + unitsPerEm / 2) / unitsPerEm + 32) / 64;
int surprise = hdmx.width(i, j) - roundedTtAw;
magWriter.writeValue(surprise);
}
}
magWriter.flush();
byte[] magBytes = magWriter.toByteArray();
