I'm not sure my previous message ever made it up here. So I'll repeat it again. Does anyone know anything about the Datatypes library. I need info concerning whether I can scale bitmaps and how. Also concerning the Amigaguide datatype. It seems not to work when I try to jump to a hypertext button. Please answer with any info you have, or even if you know somebody who knows. Thanks, >> Mike Uman >> Oxxi Tech Support

As far as I know, the standard bitmap datatypes don't scale. I'm sure that you could write one which did. Of course, I haven't carefully read the datatypes stuff in the DevCon notes because I haven't had to deal with them programmatically. Have you tried calling CATS or posting in the Bix closed developer support areas? — Dale L. Larson, Intangible Assets Manufacturing — INTERNET:dale@iam.com

Hi Dale, Yeah, I have tried calling Carolyn and unfortunately she has no experience with the datatypes library. I have had some high hopes concerning it's use in SBase4. It seems though, that I will be unable to use it for the application I desire. I'd like to read the datatype to a bitmap structure and Scale it myself if I have to. I need to be able to display the image in a rectangle on form. Thanks, >> Mike Uman >> Oxxi Tech Support

I think there is an intuition or graphics library call for scaling bitmaps. I may have seen it mentioned in devcon datatypes stuff. There is a way to scale an image in datatypes, but I don't know how integrated it is. All I wanted to do was get a bitmap and palette from files of different types, but the datatypes seemed to do everything but that.

Hi Arnie, I know about the Graphics library call BitMapScale() but I need to be able to get a Bitmap structure to scale. Datatypes renders to the rastport of the window. I was thinking about trying to make a dummy window pointer, but I don't think it is a good idea. I think I will try sending EMail to David Junod, the author of the datatypes library.
