Large diffs from font rendering

まだ誰も着手していません。

Hello, thanks for the module.

I know that you are aware of the issues but I'm trying to understand what I can do about them. In particular I see a large difference between two images that are similar, with some apparent minor difference in the font causing the failure.

I've inspected the generated images and they are the same (physical) size, dpi, etc.

I see some discussion (e.g. https://github.com/astropy/astropy/pull/7150) about maybe just choosing the font appropriately to minimize this. Is that the current recommended solution?

I also gave the perceptual hash (#21) a go and it does generate identical hashes for the two images, which is nice. However I haven't yet had time to look into that more to really understand what it is doing so don't necessarily want to rely on it.

Baseline:

Generated. This is missing the title as `remove_text=True` is enabled (#68 would be relevant here):

Diff:

This is coming from https://github.com/panoptes/POCS/pull/735

(Note that even getting these images out of travis was a huge pain as travis doesn't allow artifacts to be uploaded on pull-requests...but that's a different issue).

まず、POCS pull request 735 の画像比較を再現し、astropy pull request 7150 で参照されている議論を確認してください。フォントレンダリングの違いを issue 21 の perceptual-hash アプローチと比較してください。具体的で文書化された推奨事項または明確に定義された fix が存在すれば、issue は解決です。
