Making mods widescreen compatible

[Tormentor667]

Fellow doomers, as GZDoom supports widescreen graphic lumps I wanted to ask how this feature actually works - there isn’t a documentation at the wiki yet on how to implement them.

For the original releases, people are already working on enhanced replacements here: viewtopic.php?f=46&t=67843&start=105

I wonder, if I want to add widescreen compatibility to my old mods, how would I do that to make the graphics seamlessly fit also on all the other possible resolution ratios?

Best regards and thanks,
Dan

*EDIT*
I tried to implement it into Blade of Agony for now but with the latest development version of GZDoom from today (April 13th, 2020) it doesn't seem to work.

This is what I've added to the GAMEINFO lump

Code: Select all

FULLSCREENAUTOASPECT = "3"

according to drfrag's post from the original thread:
Subject: Option to change aspect ratio of menu background images

You need a GAMEINFO flag:

Code: Select all

Due to backwards compatibility needs and for flexibility this needs to be controlled by a gameinfo setting (fullscreenautoaspect):

0: Treat all images as having an aspect ratio of 4:3, this is the default for compatibility reasons
1: Scale all images to fit the screen, i.e. either pillarbox or letterbox them.
2: Scale all images to fill the screen.
3: Scale all images so that the center 4:3 area is always fully visible. This is the recommended mode for 16:9 images designed to be shown with the sides being cropped on narrower displays.

and wide pics of course, and a recent devbuild.

This is the image that I have prepared in a aspect of 21:9

And this is how it ends up ingame (image squished, black letterboxes left and right):

What did I do wrong?

There are several open bug reports I've made that touch on all of these issues. Let's wait for Graf to have time to take a look at them. He's currently busy doing some heavy engine refactoring work.

Thanks for the hint regarding this. Just for the record: The GAMEINFO is correct and the image size in the 21:9 aspect as well? That way I can at least prepare a few things

The MAPINFO/GameInfo-block part is correct, but there are still some scaling issues that Graf hasn't commented on yet.
