Evals / image / Format conversion
Rasterise an SVG
Export tiger.svg as a 1024 pixel wide PNG called tiger.png.
The task
The reference answer shows the job can be done with deft. It is not an agent run.
deft image resize tiger.svg --size 1024x --upscale -o tiger.png
The files are not kept here, because tiger.svg is under AGPL. Its source is linked.
Input
