I have an image that is resized within the app however it looks pretty terrible depending on what it has been scaled to and I dont know how to fix this…

enter image description here

Making the image bigger is not the solution and I have already set the mag and min filters as follows…

gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MIN_FILTER, GL10.GL_LINEAR);
gl.glTexParameterf(GL10.GL_TEXTURE_2D, GL10.GL_TEXTURE_MAG_FILTER, GL10.GL_LINEAR);

Does anyone know how I can avoid this?

EDIT: Also why is there a black outline around this as there is no border around it in Photoshop, the background is transparent.
Thanks

    Strange black borders are normally a sign of using premultiplied alpha when the rendering library isn’t expecting it, or vice versa.

    See this question: iPhone opengl es alpha-blending. I have black color in edge

    It’ll also make the antialiasing go funny which will make your image look strangely pixelated, so if that’s the problem, it could well fix that as well.
