I want to get a image by eglCreatePixmapSurface;but it show the
following error in log when GL10 be used.
ERROR/libEGL(2154): call to OpenGL ES API with no current context
(logged once per thread)
my code is :
public void init() {
if (!isInit) {
// initialize egl
egl = (EGL10) EGLContext.getEGL();
display = egl.eglGetDisplay(EGL10.EGL_DEFAULT_DISPLAY);
egl.eglInitialize(display, null);
int[] configWant = {
EGL10.EGL_SURFACE_TYPE,
EGL10.EGL_PIXMAP_BIT,
EGL10.EGL_RED_SIZE, 5,
EGL10.EGL_GREEN_SIZE, 6,
EGL10.EGL_BLUE_SIZE, 5,
EGL10.EGL_DEPTH_SIZE, 16,
EGL10.EGL_NONE };
EGLConfig[] configs = new EGLConfig[1];
int[] num_config = new int[1];
egl.eglChooseConfig(display, configWant, configs, 1,
num_config);
bmp = Bitmap.createBitmap(100, 100, Config.ARGB_8888);
g = new Canvas(bmp);
p = new Paint();
context = egl.eglCreateContext(display, configs[0],
EGL10.EGL_NO_CONTEXT, null);
surface = egl
.eglCreatePixmapSurface(display,
configs[0], bmp, null);
egl.eglMakeCurrent(display, surface, surface, context);
gl = (GL10) context.getGL();
initData(gl);
delta = -1;
if (fps > 0) {
delta = 1000 / fps;
}
isInit = true;
}
}
@Override
public void run() {
init();
while (isInit) {
if (running) {
int w;
int h;
loopTime = System.currentTimeMillis();
synchronized (this) {
w = width;
h = height;
}
if (resize) {
resize(gl, w, h);
resize = false;
}
runX();
paint(gl);
// egl.eglSwapBuffers(display, surface);
g.drawBitmap(bmp, 0, 0, p);
if (egl.eglGetError() ==
EGL11.EGL_CONTEXT_LOST) {
Context c = getContext();
if (c != null && c instanceof Activity)
{
((Activity) c).finish();
}
}
long time = System.currentTimeMillis() -
loopTime;
try {
Thread.sleep(Math.max(1L, (long) delta
- time));
} catch (InterruptedException e) {
e.printStackTrace();
}
} else {
try {
Thread.sleep(50);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
protected void initData(GL10 gl) {
gl.glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
gl.glMatrixMode(GL10.GL_PROJECTION);
gl.glLoadIdentity();
GLU.gluOrtho2D(gl, 0.0f, 1.3f, 0.0f, 1.0f);
gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
gl.glShadeModel(GL10.GL_SMOOTH);
}
... ...
How can I get a image from egl?
I want to add 3D effects in my program using GL
kind regards,
