What's the best way to open an overscan screen in C under AmigaDOS 1.3? I'm writing a simulation of cell growth which will need to be transfered to videotape, and we want it to look as good as possible... I'm using SAS/C 5.10 Your aid will be appreciated -- Jack

However, if it is for transfer to videotape only, and you don't care if you have full mouse travel to the right and bottom, then just adjust your Preferences so the upper leftcorner of the workbench is as far up/left as you want, and open the overscan size screen you want. -- ========================================================================== Carolyn Scheppner -- Tech.

Peter Cherna (in charge of Intuition) asked me to correct/append my statement that we do not support overscan screens under 1.3. The 1.3 OS does not provide full support for overscan screens. However, besides the solution I listed above (which I feel is safe and perfectly suitable for the stated application), there is is also Jim Mackraz's 1988 Devcon article/example on Overscan where Jim provides some more complex but relatively safe methods for creating and using overscan screens under 1.3 with full mouse travel. -- ========================================================================== Carolyn Scheppner -- Tech.

Yes, however you will have to adjust the screen offset so that your overscan screen is in the right place. I have not decided what I like best, messing with preferences settings, or messing around with the layers ViewPort structure (VP->DyOffset and VP->DxOffset) and then calling RethinkDisplay() or the equivilant. (That manual is it home, the rest of this is from *old* RKM Vol 1, so if it is wrong, forgive me. The concept is right I believe). Currently I am leaning toward messing with the ViewPort structure, as it seems to be the easiest. I've not had to deal with this yet. brian moffet -- O Fortuna - velut luna - statu variabilis - semper crescis - aut decrescis vita detestabilis - nunc obdurat - et tunc curat - ludo mentis aciem egestatem - potestatem - dissolvit ut glaciem brianm@sco.com Speaking for Myself
