Very cool little app! Although I have never figured out where the gif is saved or if it works. I know this app has 3 years almost but would appreciate help in that regard. Even if it doesnt work - I'm loving it.
Hi, the program throws an error when I try running it on macOS Mojave 10.14.6 in terminal or iTerm. Here's what the report is:
dyld: lazy symbol binding failed: Symbol not found: _objc_opt_respondsToSelector
Expected in: /usr/lib/libobjc.A.dylib
dyld: Symbol not found: _objc_opt_respondsToSelector
Expected in: /usr/lib/libobjc.A.dylib
Referenced from: crtview-mac (which was built for Mac OS X 10.15)
I really like this filter, though I have a minor issue in that exporting gifs isn't exactly 1:1. I found a way to use dithering in a way that can mimic transparency effects when viewed through one of the filters, using horizontal strips of color. But when I try to export the gif, the end result fails to capture the effect, despite it working fine when viewed through the filter itself. Is there any way around this issue?
It might be the limited capabilities of the gif file format, like it only supports a maximum of 256 colors (8-bit), while the filter makes use of 24 bit colors.
One way to capture it better might be to use something like OBS (Open Broadcaster Software) to capture it like a video. But then you will have compression artefacts, which may or may not invalidate the effect you want to capture.
I don't really know of any way to capture a video which fully do justice to the filter. It really is best viewed live.
Thanks :) Is there any way to adapt this program to display the output of another program? Typically an old game, in order to emulate its historical rendering?
I guess it should be possible, in the same way it is possible for video recording or streaming applications, to read the display of another program - but I don't know how that stuff really works.
i love it so much but for some reason i cant export my gifs, even tho its displaying "exporting gif" at the top of the screen. and im a windows user. can someone help me please?
At the moment it is only possible to export a gif if you load an animated gif with more than one frame of animation. For still images, you have to take a screenshot instead.
If it fails to export animated gifs, I'll try to help - maybe if you could share one of the gifs which fails, I could try it and see where it goes wrong.
Also, another thing that just occured to me, it might be worth trying to put the crtview exe and your gif in the same folder before trying to export
Hello! I was trying to write a makefile to compile from the git repo on debian, but I’m no C expert and couldn’t get headers (I think) to be found properly. Could you share how you compiled the linux build for this page?

Has anyone tried to combine the crt filter with Dosbox yet? :D
actually, yes 🙂 https://mattiasgustavsson.itch.io/dosbox-crt

For gifs to be saved, you need to open an animated gif - it does not save gifs for static images
Aaaa, gotcha! I thought it is adding that animated scan-lines to the still image. All clear, thank you for explaining.
where can i see the the crtview.gif file? T__T this is really cool and fun!!
Is there a license to use this for our own projects?
the code is under a dual MIT/publicdomain license - basically, free for all, use however you want
What a nice tool. It's cool to see modern game images with this CRT filter hehe.
Lovely Tool :)
Mattias, could you add next/previous hotkeys?

Any idea what the problem is? Cheers.
Well reading the last line, maybe the .exe was made for macOS 10.15, while you ran it on 10.14.6
Read the error message ;)
I thought exes were only native to windows OS
Well there's different types of executable files. Some are for Windows and some are made for macOS.
ah, i see. so executables with different names
Kinda yeah, and probably the content/encoding/binary/etc of the file.
Very cool but can you give CRT effect without border/monitor, only the effect? that would be really2 cool
I'd also be interested in a version without the fake monitor graphics.
I second that (in fact, third)
i adore this.. so fun and useful.. opens my third eye really
Any plans to make this for videos?
No, no plans

Build instructions for linux are in the readme.md in the git repo. You don't need a makefile, you just call gcc, as there is just a single c file:
gcc source/main.c -lSDL2 -lGLEW -lGL -lm -lpthread
SDL2 and GLEW are required - if you don't have them installed you can do so by running
sudo apt-get install libsdl2-dev
sudo apt-get install libglew-dev
Thanks! I just wanted a makefile for convenience, but somehow the same command works outside and not inside the makefile.
