Store the given texture in memory as a PNG file. Use gdk_texture_new_from_bytes() to read it back. If you want to serialize a texture, this is a convenient and portable way to do that. If you need more control over the generated image, such as attaching metadata, you should look into an image handling library such as the gdk-pixbuf library.

将指定的 texture 存储为内存中的 PNG 文件。 使用 gdk_texture_new_from_bytes() 读取它。 如果您想序列化一个纹理，这是方便且易于移植的方式。

GDK provides a number of threadsafe texture loading functions: gdk_texture_new_from_resource(), gdk_texture_new_from_bytes(), gdk_texture_new_from_file(), gdk_texture_new_from_filename(), gdk_texture_new_for_pixbuf(). Note that these are meant for loading icons and resources that are shipped with the toolkit or application.
