C++ (Cpp) image_external_form Examples

Example #1

File: main.cpp Project: popasquat89/ME4573

void LoadTextures(const char *textureName) {
	std::cout << "Loading Texture " << textureName << std::endl;
    int w, h, c, b;

    void *p = image_read(textureName, &w, &h, &c, &b);

    int i = image_internal_form(c, b);
	int e = image_external_form(c);
    int t = image_external_type(b);

    image_flip(w, h, c, b, p);

    glTexImage2D(GL_TEXTURE_2D, 0, i, w, h, 0, e, t, p);
    free(p);

	std::cout << "Done Loading Texture " << textureName << std::endl;
}
