Requesting help for Linux Build with ASSDraw3 #112

Closed heptahex closed 3 years ago

heptahex commented 3 years ago

I, recently built for my Linux machine from source using the guide on the repo's homepage. Everything works well but I still don't understand why both Official Aegisub and this fork don't contain ASSDraw3 in Linux build. Did I miss something else in building Aegisub? If I missed something how can I fix it. Thanks.

ASSDraw3 depends on agg, which is dead for a long time. Building a working ASSDraw3 won't be straightforward, it may need some fixes in the code.

Ok. I get it. Thank you.

To elaborate a bit on the state of AssDraw: The latest commit to Aegisub/AssDraw was in 2012, there was a fork by biki-desu in 2014 which makes it (somewhat) work with wxGTK (wxGTK from 2014 that is).

With the GTK2 version of wxWidgets-3.0 it mostly works, nodes are rendered and the draw command can be copied to Aegisub, but attempting to set a background image leads to errors and eventhough something from the image gets rendered it doesn't react to zooming and panning, so it cannot be used for accurate positioning. (GTK2 is by now no longer supported.) With the GTK3 version however, not even the drawing nodes get rendered.

At one point, I intented to make an attempt to at least make the image work correctly in GTK2, but gave up and only fixed some build-related things and the incorrect license info. If someone considers this to be worth the time and wants to take a stab at this, here's a zipped bare git repo including biki-desu's GTK changes and my minor fixes: assdraw_bare-git.zip (either git clone assdraw/.git assdraw_work after unzipping, or run git reset --hard HEAD inside the unzipped assdraw directory to get all working files)

However, if the panning and zooming PR get's merged in Aegisub upstream, considering that Aegisub already has tools for vector clipping, it may perhaps be easier and better to add a vector drawing tool to Aegisub itself, instead of updating AssDraw.
