BlackBerry - 如何调整大小和存储图像？

Question

我需要将图像缩放到小图像并将图像存储到黑莓设备中（作为小图像）？

Answer 1

如果图像被打包，甚至通过网络或文件系统来源，那么

缩放图像就足够简单了。

public EncodedImage scaleImage(EncodedImage source, int requiredWidth, int requiredHeight) {  
  int currentWidthFixed32 = Fixed32.toFP(source.getWidth());  
  int requiredWidthFixed32 = Fixed32.toFP(requiredWidth);  
  int scaleXFixed32 = Fixed32.div(currentWidthFixed32, requiredWidthFixed32);  
  int currentHeightFixed32 = Fixed32.toFP(source.getHeight());  
  int requiredHeightFixed32 = Fixed32.toFP(requiredHeight);  
  int scaleYFixed32 = Fixed32.div(currentHeightFixed32, requiredHeightFixed32);  
  return source.scaleImage32(scaleXFixed32, scaleYFixed32);  
}  

这将返回图像的副本，根据您需要的宽度和高度进行缩放。
