Full screen shows small image..

[Keatah]

I noticed that the Full Screen mode shows a much smaller 640x480 image. It isn't full-screen.

It will depend on your screen resolution. AppleWin will scale by the maximum (same) integer amount in X and Y. What is your X/Y screen resolution?

[Keatah]

1024x768

[tomcw]

AppleWin will try to integer scale the base resolution of 560x384.
In your case it can't do anything because your screen width is too small.
NB. We tried floating-point scaling, but the StretchBlt operation gave poor results.

Note to self: Try float scaling using SetStretchBltMode(hdc, HALFTONE).

I've already tried a few things, including HALFTONE IIRC, but please have a play. My current opinion is that we'd have to move away from GDI (or at leat StretchBlt) to get a clean scale. Cheers, Nick.

I see. I upped the resolution and got a full-screen. I do, however, like the overall look of the scaling when Applewin stays at its 560x384. Scaling up blurry artifacting seems a little tacky and not quite right. Perhaps flat?

I'm running AppleWin on a GpdWin handheld (Windows 10 based) and the image is quite small on the 1280*720 resolution screen. Would be great to be able to stretch it a bit but keep the aspect ratio (or not).

From the release notes:

NB. If your screen resolution is smaller than 1120x768, then you will get no scaling in full-screen.

As you can see from above, if we "stretch it a bit" (using the current Windows graphics interface, GDI) gives poor quality results.
