FileOptimizer

[nikkho]

Default browser would be ideal

​Thanks. CHM file is not updated since months ago. I will try to fix it ofr the next release.

[nikkho]

nikkho, FileOptimizer 14.10.2534 in the Plugins32 folder contains 64-bit applications:
​jpeg-recompress.exe, pngquant.exe, gifsicle.exe.
Please fix this.

Thank you. Gifsicle was my mistake, so it is fixed.
Regarding pngquant and jpeg-recompress, they are not distributing 32 bit binaries, so not much I can do.

Hi Nikkho, why don't you actually use Pingo for optimizing PNG's when "keep metadata" is enabled? Does it actually remove metadata?

Thanks. When I added pingo lots of time ago it did not keep metadata. I checked and now it supports -strip flag, so I have updated it.

I was unexpectedly kicked out of many communities for plagiarism.
Upon learning, I realized that this is due to the mention of my old nickname in your changelog.
I think you should change the changelog.

I never said that any of the tools you use were written by me. I only recommended you what I was familiar with, mainly from the demoscene.

PCXLite wrote by Sol, as did some of your set. Sol webpage - https://sol.gfxile.net/

/Thank

[necros]

can you point to PCXlite - I don`t see it on his site?

I do not understand why this could be hurting you, but no problems. Let me know what you exactly need I to change in the Changelog and I will do.

It's obviously lossy but almost imperceptible, and the gains are on a league of its own. Truly impressive.

[MegaByte]

What do the quality metrics look like? butteraugli, DSSIM, etc.? This is very far from imperceptible by my eye.

It's obviously lossy but almost imperceptible, and the gains are on a league of its own. Truly impressive.

How do you measure quality(loss) difference?

[Gonzalo]

@dado @MegaByte:

You're right, in those images from the benchmark the difference is quite noticeable. Nevertheless, those are artificial images, the kind you might get from a screenshot, and for that JPG is not really good. IDK why did they use them, but I'd rather pick PNG for that particular case.

In my personal tests I used scanned pages from books and photographs from the real world (already lossy). I didn't use any quality metric, it's just my subjective opinion after comparing them at 100% zoom and seeing no noticeable difference. See attachment for an example.

[Krishty]

I didn't use any quality metric, it's just my subjective opinion after comparing them at 100% zoom and seeing no noticeable difference. See attachment for an example.

I must admit, I was impressed by your example as well. But when I used GIMP to save the image at a target size of 243 KiB, I couldn’t see a noticeable difference at 100% zoom either, even though GIMP’s JPG encoder is far from optimal, so … not convinced (yet). This really needs a metric.

[Gonzalo]

Didn't think of that... Maybe talk to the developers? They responded very quickly to my pull request.

In any case, I don't know if GIMP can be used from a script, or if the results are consistent.... Maybe worth investigating, especially for web devs

Regarding the JPG CMYK bug and after testing with this sample
"https://en.wikipedia.org/wiki/File:Channel_digital_image_CMYK_color.jpg" the following programs were tested:

jpegoptim ok
jpeg-recompress skipped it.
jpegtran ok
mozjpegtran ok
Leanify ok
pingo convert the CMYK to RGB
ECT ok
Jhead ruined the colors <====== this one.
Guetzli skipped the file.

[necros]

What are layered PDFs, what can be wrong while processing it? (Skip layered PDFs option caught my eye)
P.S. FO calls Commandline: rehuff.exe when in fact it`s absent - was replaced by rehuff_theora I guess?

Thank you for the findings. I have implemented a quick and dirty CMYK detection and prevented jhead execution if so.

Problem is that if processing a layered PDF because some content groups would be removed.
Regarding rehuff, you are right. That was a bug. It has been solved: https://sourceforge.net/p/nikkhokkho/code/1672/

[SvenBent]

just a useless FYI

I'm running some test on the compression tools of file optimizer
Mostly out of curiosity to learn the behavior of the tools but also to rule out anything that is worthless to use (just a waste of time) and to see if order of the tools matters

I'M dumping it slowly in another thread in batches of jpegs of a time

I'm currentkly gathering a 500gb + jpeg test library (all human potrait ish photos). so... a lot of testing to come

Thanks for sharing your opinion.
Indeed the order matters. Thing here is that execution order will not get best results in all files. Anyway, looking forward to your results. It is a complex task, specially because you are only convering JPEG files, while FO supports several filetypes.

[SvenBent]

Though it would be easier to ask here than to check the programs process

Besides ect, pingo,leanify,mozjpegtran, what other tools does file optimizer used?

so far order of tools does not really seem to matter it looks liek there is no a lot of heritage and all tools does a full reconstruction of the file data. (unlike our many png tools). Except for pingo since it (according to fhanau) removes 18 bytes of the jpeg header, which can cause some compatabilities issues.
sdo it looks like pingo hasto be at the end for either
using - strip and getting the last 18 bytes out of there or
not using -strip but to still have meta data removed by prior tools


im still teating though. started on a 16gb 27.000 files data set but its taking a long time

Here they are: https://sourceforge.net/p/nikkhokkho...bug/Plugins64/
Your explanation makes sense, but in my tests execution order really produced different results, specially on PNG files.

Hi @nikkho. Thanks for this convenient tool!
Are you still maintaining the software? I've found a few issues... should I report them on SourceForge?
Would you consider moving to GitHub one day? Thanks again.
