获取OpenGL最大纹理大小 [英] Get OpenGL max texture size

问题描述

我正在开发一个可广泛用于位图的Android应用，我正在寻找一种可靠的方法来在不同设备上获得OpenGL的最大纹理大小.
我知道最小尺寸= 2048x2048，但这还不够好，因为那里已经有分辨率更高的平板电脑(例如2560x1600)
那么，有没有一种可靠的方法来获取此信息?

到目前为止，我已经尝试过:

I'm developing an Android app that's going to work with bitmaps extensively and I'm looking for a reliable way to get the maximum texture size for OpenGL on different devices.
I know the minimum size = 2048x2048, but that's not good enough since there are already tablets out there with much higher resolutions (2560x1600 for example)
So is there a reliable way to get this information?

So far I've tried:

• Canvas.getMaximumBitmapWidth()(返回32766，而不是2048)
• GLES10.glGetIntegerv(GL10.GL_MAX_TEXTURE_SIZE ...)(返回0)

我正在使用最低SDK = 15(ICS)，并正在Asus Transformer TF700t Infinity上对其进行测试

I'm working with minimum-sdk = 15 (ICS) and I'm testing it on a Asus Transformer TF700t Infinity

有人知道另一种获取方式吗? 还是我必须编译其最大画布大小的已知GPU列表?

Does anyone know another way to get it? Or will I have to compile a list of known GPUs with their max canvas size?

推荐答案

尝试使用此代码

int[] maxTextureSize = new int[1];
GLES10.glGetIntegerv(GL10.GL_MAX_TEXTURE_SIZE, maxTextureSize, 0);

maxTextureSize存储已解码图像的大小限制，例如4096x4096、8192x8192.请记住在 MainThread 中运行这段代码，否则您将得到零.

maxTextureSize stores the size limit for decoded image such as 4096x4096, 8192x8192 . Remember to run this piece of code in the MainThread or you will get Zero.
