如何捕捉错误“位图太大而不能上传到纹理' [英] How to catch error 'Bitmap too large to be uploaded into a texture'
问题描述
我的Android应用程序处理非常大的位图。正因为如此，我对图像视图接通硬件加速关闭。 然而，一些用户已经设置了开发人员选项强制GPU加速功能开启。这就导致了错误位图太大而不能上传到纹理'。 如果我检查使用isHardwareAccelerated（）认为，它始终返回false。
My android application handles very large Bitmaps. Because of this, I turned hardware-acceleration off on the image views. However, some users have set the Developer-Option 'Force GPU-Acceleration' turned on. This leads to the error 'Bitmap too large to be uploaded into a texture'. If I check the view using isHardwareAccelerated(), it always returns false.
有没有办法赶上OpenGL的错误位图太大，无法上传到纹理？
Is there any way to catch the OpenGL-Error 'Bitmap too large to be uploaded into a texture'?
推荐答案
位图是由像素组成的，你可以指望位图矩阵像素数,,设置限制你的位图的像素数。在OpenGL我不能说，但总的来说，我们可以很容易地处理它们，也有一种方法
bitmap.inSampleSize（）;
Bitmap is Composed of Pixels and you can count the number of pixels in the bitmap matrix ,, set a limit to your number of bitmap pixels . In OpenGl i can't say , but in general we can easily handle them , also there is a method
bitmap.inSampleSize();
如果您分配
Bitmap.inSampleSize()= 1;
那么原来的位图的像素将被加载。
then the original bitmap pixel will be loaded.
Bitmap.inSampleSize()= 2;
则像素将成为原来的一半像素。
then the pixels will become half of the original pixel.
Bitmap.inSampleSize() = 4
则像素将变成原始像素的1/4。 这种方式可以减少像素大小的位图， 我已经在我的程序做这个事情，希望它会与你工作了。
then the pixels will become 1/4 of the original pixel . This way you can reduce the size of the pixels in the bitmap , I have done this thing in my program , hopefully it will work with you too.
