我需要将图像提升到小片,并将这种形象储存在黑莓装置中(作为小的形象)?
如果对图像进行包装,甚至从网络或档案系统上传播,那么图像的扩大就足够了。
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);
}
