imageview设置图片时超长超大图片超出限制（OpenGLRenderer: Bitmap too large to be uploaded into a texture (996x9116, max=4096x4096)）

问题：遇到超长图片，宽长等比缩放，比如宽度同屏幕同宽，长度等比放大，放到后遇到长度超出OpenGLRenderer的最大限制，导致图片无法显示出来：

解决办法：

            //图片超出GPU对于openglRender最大限制缩放处理
            if(height > getOpenglRenderLimitValue()){
                width = width * getOpenglRenderLimitValue() / height;
                height = getOpenglRenderLimitValue();
            }

  public static int getOpenglRenderLimitValue() {
        int maxsize ;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            maxsize = getGLESTextureLimitEqualAboveLollipop();
        }else {
            maxsize = getOpenglRenderLimitBelowLollipop();
        }
        return maxsize ==0 ? 4096 : maxsize;
    }

    private static int getOpenglRenderLimitBelowLollipop() {
        int[] maxSize =new int[1];
        GLES10.glGetIntegerv(GLES10.GL_MAX_TEXTURE_SIZE, maxSize,0);
        return maxSize[0];
    }

    private static int getGLESTextureLimitEqualAboveLollipop() {

        EGL10 egl = (EGL10) EGLContext.getEGL();
        EGLDisplay dpy = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
        int[] vers = new int[2];
        egl.eglInitialize(dpy, vers);
        int[] configAttr = {
                EGL10.EGL_COLOR_BUFFER_TYPE, EGL10.EGL_RGB_BUFFER,
                EGL10.EGL_LEVEL, 0,
                EGL10.EGL_SURFACE_TYPE, EGL10.EGL_PBUFFER_BIT,
                EGL10.EGL_NONE
        };
        EGLConfig[] configs = new EGLConfig[1];
        int[] numConfig = new int[1];
        egl.eglChooseConfig(dpy, configAttr, configs, 1, numConfig);
        if (numConfig[0] == 0) {// TROUBLE! No config found.
        }
        EGLConfig config = configs[0];
        int[] surfAttr = {
                EGL10.EGL_WIDTH, 64,
                EGL10.EGL_HEIGHT, 64,
                EGL10.EGL_NONE
        };
        EGLSurface surf = egl.eglCreatePbufferSurface(dpy, config, surfAttr);
        final int EGL_CONTEXT_CLIENT_VERSION = 0x3098;  // missing in EGL10
        int[] ctxAttrib = {
                EGL_CONTEXT_CLIENT_VERSION, 1,
                EGL10.EGL_NONE
        };
        EGLContext ctx = egl.eglCreateContext(dpy, config, EGL10.EGL_NO_CONTEXT, ctxAttrib);
        egl.eglMakeCurrent(dpy, surf, surf, ctx);
        int[] maxSize = new int[1];
        GLES10.glGetIntegerv(GLES10.GL_MAX_TEXTURE_SIZE, maxSize, 0);
        egl.eglMakeCurrent(dpy, EGL10.EGL_NO_SURFACE, EGL10.EGL_NO_SURFACE,
                EGL10.EGL_NO_CONTEXT);
        egl.eglDestroySurface(dpy, surf);
        egl.eglDestroyContext(dpy, ctx);
        egl.eglTerminate(dpy);

        return maxSize[0];
    }
