//----------------------------------------------------------
void ofTexture::readToPixels(ofFloatPixels & pixels){
#ifndef TARGET_OPENGLES
	pixels.allocate(texData.width,texData.height,ofGetImageTypeFromGLType(texData.glTypeInternal));
	bind();
	glGetTexImage(texData.textureTarget,0,ofGetGlFormat(pixels),GL_FLOAT,pixels.getPixels());
	unbind();
#endif
}

Example #2

#ifndef TARGET_OPENGLES
	getTextureReference(attachmentPoint).readToPixels(pixels);
#else
	bind();
	int format,type;
	ofGetGlFormatAndType(settings.internalformat,format,type);
	glReadPixels(0,0,settings.width, settings.height, format, GL_FLOAT, pixels.getPixels());
	unbind();
#endif
}
