Chris,

I've never learned to use Rembrandt.Panel. Pity there isn't an instruction document similar to that for Leonardo.

Actually there is an instruction document. It's Rembrant.html

cg> Q1. does this only apply to *.Pict ?

Probably. Can Rembrandt open any file other than Pict?

Yes. In fact Rembrandt used to be the only tool for opening gif and other files. But now by default ImageDocs is associated with gif files instead of RembrandtDocs. In Windows System 3 this is changed using IniEdit.Panel. I'm not sure how it's done under N-O.

cg> Q3. Since converting: *.gif <--> *.Pict is possible under n-o

PictConverters has *.gif --> *.Pict. Where is *.Pict --> *.gif ?

It's right there in the PictConverters.Tool at the bottom. The example given is: PictConverters.PictToGIF Clown.Pict => Clown.gif ~ I use this facility to create graphics from Leonardo for web projects. I'll sometimes create graphics using Leonardo/Vinci and then export them using PictConverters to GIF or other formats.

cg> Q3. Since converting: *.gif <--> *.Pict is possible under n-o, can I rescale *.gif ?

Converting to Pict seems too inefficient for Web browsing.

I don't think that would be a problem since since is very fast on modern computers. But module Pictures can directly load Gif files anyway. In fact that's what I believe the HTML browser is already doing (converting to Pict on the fly). Look at the documentation from module Pictures: (* Open the picture file with name from disk. Any graphic file format listed in the PictureConverters section of the Registry can be loaded (e.g. GIF, JPEG, XBM, BMP). *) PROCEDURE Open (P: Picture; name: ARRAY OF CHAR; color: BOOLEAN);

How about writing fast scaling commands as part of the Images package?

GfxImages does precisely that. And Images is better than Pictures/Rembrandt anyway since it supports more than just 256 colors.

Web browsing capabilities in Oberon and AOS certainly leave many opportunities for improvements.

True. The WebNavigator package shows a lot of promise, but it needs work. One thing that I like better about the old web browser is that it's better integrated into Oberon. (For instance I don't see any way to "cut/paste" from WebNavigator). I think what would be nice would be a browser based on the WebNavigator HTML parser, but that used the LayLa layout engine to create an Oberon panel on the fly that supported frames and had better support for tables than the old Oberon web browser. Just a thought. Regards, John M. Drake __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com
