oxigen's Issues

Docker instruction syntax incorrect

❯ docker run ghcr.io/yuriizinets/oxigen:latest -p 9001:8000
docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "-p": executable file not found in $PATH: unknown.
ERRO[0001] error waiting for container:

I managed to resolve this by swapping the order around, and noticed there is a pull request which has this fix ready as well. Thanks @mre

#10

Support SVG images

Docker image seems broken

After running the docker image, it seems to not load the web ui. Logs say it's ready at port 8000. No other warnings or anything. Any ideas?

EDIT: I figured it out. The container calls for port 8000 so the ports should be

80:8000 not 80:80 as shown in the readme :)

EDIT2: Yeah, the Docker image needs work. Tried it in a few browsers and it's not loading any images. Even with the default values.

Error handling

Handle errors and give reasonable response, for both API and UI

Logo image size

After we got control over the size of the image, there was a problem with the size of the logo. If we want to get a smaller output image, then the logo takes up almost the entire space, for example:

Image width: 600;
Image height: 300;

And vice versa, if you set the dimensions larger, the logo comes out too small:

Image width: 2400;
Image height: 1200;

As a suggestion, either add control over the size of the logo as well, or at least calculate its size as a percentage

Fonts are not loading from embed.FS

While running oxigen binary (not as docker container), there is an error related to fonts loading (originally reported here).

Panic when using non supported format

I just tried the tool from the docker container and used an SVG as image (which seems to not be supported). The app then paniced unrecoverably.

I suggest not panic-ing in a web service and add proper error handling instead.
