所以我有一个使用decodeFile加载图像的函数 - 然后我调整照片大小并将其绘制到画布中。这在我的Moto Droid 2.2.3&我的Nexus 4.1.1 - 但是在每次createScaledBitmap触发时我的HTC 4.0.3崩溃并抛出错误“无法创建SkBitmap”......
这是代码示例...
// create image bitmap
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inPurgeable = true;
bmOptions.inSampleSize = 2;
Bitmap rawImage = BitmapFactory.decodeFile(imageURL,bmOptions);
Bitmap bmp = Bitmap.createBitmap(rawImage);
float ratio = 0;
int maxHeight = 900;
int maxWidth = 900;
float height = bmp.getHeight();
float width = bmp.getWidth();
Log.d("HEIGHT",""+height);
Log.d("WIDTH",""+width);
int nh = 0;
int nw = 0;
// check if current width is larger
if(width > maxWidth){
ratio = maxWidth / width;
float newWidth = maxWidth;
float newHeight = height*ratio;
nw = Math.round(newWidth);
nh = Math.round(newHeight);
Log.d("NEW RATIO",""+ratio);
Log.d("NEW HEIGHT",""+newHeight);
// RESET HEIGHT AND WIDTH
height = height * ratio;
width = width * ratio;
}
if(height > maxHeight){
ratio = maxHeight / height;
float newWidth = width*ratio;
float newHeight = maxHeight;
nw = Math.round(newWidth);
nh = Math.round(newHeight);
Log.d("NEW RATIO",""+ratio);
Log.d("NEW HEIGHT",""+newHeight);
height = height * ratio;
width = width * ratio;
}
bmp = Bitmap.createScaledBitmap(bmp,nw,nh,false);
Bitmap img = Bitmap.createBitmap(bmp,0,0,655,655);
就像我说的,这在我的其他设备和Android版本上运行良好...我尝试过搜索,但我似乎无法找到真正解决此问题的任何内容......
我知道它是createScaledBitmap,因为如果我评论该行,一切正常 - 但我的位图不能缩放。
答案 0 :(得分:0)
回答这个问题 -
真正的问题是,在那个特定的设备上,调整大小比例太大而不适合定义的655区域,图像稍微太小 - 这导致调整大小错误但是在运行4.0.3的HTC设备上抛出“无法创建SkBitmap”错误。
解决方案是调整已调整大小的图像的尺寸。
