Examples with EGLConfig javax.microedition.khronos.egl.EGLConfig used on opensource projects

Example 1 with EGLConfig

use of javax.microedition.khronos.egl.EGLConfig in project TextJustify-Android by bluejamesbond.

the class DocumentView method getMaxTextureSize.

private static int getMaxTextureSize() {
    // Code from
    // http://stackoverflow.com/a/26823209/1100536
    // Safe minimum default size
    final int GL_MAX_TEXTURE_SIZE = 2048;
    // Get EGL Display
    EGL10 egl = (EGL10) EGLContext.getEGL();
    EGLDisplay display = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
    // Initialise
    int[] version = new int[2];
    egl.eglInitialize(display, version);
    // Query total number of configurations
    int[] totalConfigurations = new int[1];
    egl.eglGetConfigs(display, null, 0, totalConfigurations);
    // Query actual list configurations
    EGLConfig[] configurationsList = new EGLConfig[totalConfigurations[0]];
    egl.eglGetConfigs(display, configurationsList, totalConfigurations[0], totalConfigurations);
    int[] textureSize = new int[1];
    int maximumTextureSize = 0;
    // Iterate through all the configurations to located the maximum texture size
    for (int i = 0; i < totalConfigurations[0]; i++) {
        // Only need to check for width since opengl textures are always squared
        egl.eglGetConfigAttrib(display, configurationsList[i], EGL10.EGL_MAX_PBUFFER_WIDTH, textureSize);
        // Keep track of the maximum texture size
        if (maximumTextureSize < textureSize[0])
            maximumTextureSize = textureSize[0];
    }
    // Release
    egl.eglTerminate(display);
    // Return largest texture size found, or default
    return Math.max(maximumTextureSize, GL_MAX_TEXTURE_SIZE);
