Subject Re: how Get Bitmap file from SVG module?
Date Tue, 29 May 2012 08:55:40 GMT
	Hi jianlizhao,

I still have to guess what you want to do, but it sounds like:
- Insert raw data file to draw/Impress
- A special extension uses that data to proccess something and outputs a
text file
- That extension creates a Bitmap/BitmapEx AOO can display

If this is correct I see no real reason to implement/embed this
internally in AOO. If you only need the raw data in your extension, why
use AOO for it and create a file format which is potentially very big?
Why not load the raw data from an app which needs it and processes it
(the extension itself)? It seems so specialized that I would think about
a specialized solution. When you already put a *.txt file with results
next to the ODF, why not also let the raw data be aside the ODF file?
Why do you need Draw/Impress at all?

Maybe I'm wrong, still guessing your needs and plan.

Yes. Who converts this? Which instance?

Only useful when the extension is installed, no extra use for the
standard user, but much bigger files?
