Vinoth Kannan 75dbb98cca FEATURE: Add S3 etag value to uploads table (#6795) 2019-01-04 14:16:22 +08:00
Sam 766e67ce57 FEATURE: introduce lossy color optimization on resized pngs
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.

To ensure safety we only apply this optimisation to images smaller than 500k.

This commit also makes a bunch of image specs less fragile.

Sam 86255faa08 FEATURE: do not switch to JPEG unless you meet 75k byte savings
This also adjusts the algorithm to expect

- 30% saving for JPEG conversion

AND

- Minimum of 75K bytes saved

The reasoning for increase of saving requirements is cause PNG may have been
uploaded unoptimized, 30% saving on PNG is very possible

Sam 8b5e42ea16 FIX: always test and coerce to image on upload
In the past the filename of the origin was used as the source
for the extension of the file when optimizing on upload.

We now use the actual calculated extension based on upload data.
