how to save plugin's data

Hi list,

I know that some data of plugin can be stored in GIMP's pool by the function below:

gimp_set_data ("some_data", &mydata, sizeof (MyData));

But how big can this data be? If I want to store a very big data, say, a color mask of
an image, what should I do? Is it advisable to save this kind of data outside GIMP?

Thanks.

This data gets stored in the RAM and then sits there. Although there is no limit on the size of this data this functionality is not intended to store huge amounts of data. It is more about a small struct saving the preferences of a plugin or similiar stuff.

If you want to store a color mask of an image consider storing it in the image itself, e.g. in an extra channel or as a parasite. This has the advantage, that it will get stored inside the XCF format and will be available in the next gimp session.

Bye, Simon

Thank you very much.
