Allow changing jpeg quality when resizing

[jjtt]

Currently the image resize produces quite large files by probably using a very high jpeg quality setting. E.g 1000*1000 pixels was almost 1MB when another editor allowed setting quality to 75 and the file shrank to 60 kB (ugly looking, but enough for my use case)

I would like the option to set the quality before saving. A slider or a couple of predefined options to choose from.

Relates to #111 and sort of #1102

Great app :+1:

Came to report similar. With MMS image size limits, a way to scale, recompress, etc. before sending would be amazing.

For that case I use the apps

• For sending a pic 'specially formatted' direct from 'simple gallery' by 'share' functionality over 'send reduced free'

or

• For resizing multiple pics (chosen in 'simple gallery') using also 'share' and app 'photo & picture resizer' - they provide a bright batch mode but write new files (with new meta arguments like 'timestamp' etc.) - if you don't care about: fine solution :)

Hope that helped a bit‽

[Saijin-Naib]

Eh, yes and no. I know there are apps that do those functions, but the UX of that is poor, especially when it isn't necessary on other platforms.

[WoM4bLEjR]

I agree: yes&no

• Yes, there are (I call it) workarounds, to deal 'MY' matters and problems

And

• No, those 'workarounds' are definitely not UX-friendly. But: since I've chosen not to develop myself towards an UX designer or even app developer - I can (and have to) deal with changing habits (often self-tried over time) and of course there 're several other reasons (Gapps-free, FOSS, paid vs. nonpaid regularity/importance of integrated work, etc.). And - as probably all here - sometimes share experiences

@tibbi: to meet all user's wishes is in fact a wide gap. thx you let yourself not pushing down and provide ongoing improvements with your app collection. you're doing great work with 'simple gallery' - of course, I've chosen, too: to follow all of your apps

And: yeah, to share, care and improve own possibilties -even&especially in user/developer/... communities - is a wonderful chance for all :)

So, keep on the good work&exchange!

@jitt & @Saijin-Naib: thx for commenting

I think this is related to issue #1102 . My guess is that correctly resized-blurred images would result in radially lower image sizes. Current resizing creates very hard edges, which is impossible to compress well in JPG.

[Saijin-Naib]

Another possible improvement would be pushing the resized jpeg through mozjpeg or jpegoptim to do Huffman Table optimization and other lossless optimizations for the final step of resize/recompress. It can sometime net huge savings, depending upon the encoder used.

I also have been thinking a slider would be good to implement for this. Being able to control quality would be extremely helpful to many different workflows and situations. Having it also default to the existing quality level (when resizing/reencoding JPEGs), like it does when exporting in GIMP, would be helpful for the user to make better judgements when changing quality.

[OmlineEditor]

the user will independently choose the desired quality for him. It's high time to implement this feature

@OmlineEditor No it isnt. SMT are dead. They were sold. To ad company. Fork is here https://github.com/FossifyOrg

[OkyDooky]

When did that happen? And to who?
