With Adobe Acrobat running under Windoze or Mac really easy, it shrinks the files automatically looking pretty good.  In Linux?  It's looking also pretty good after scanning e.g. with XSane but the file size is sooo HUGE, even in 300 dpi A4 page...  No easy way to shrink/size optimize this in the FOSS buzzword, couldn't the geeks focus on something useful and practical instead of changing the look of the GUIs and messing with functionality all the time?

Even the "lowly" Preview has a "Reduce File Size" feature which is not
robust but works fairly well.

When Owl worked on HIS challenge about downloading recipes as PDFs, it
turned out his PDFs were MUCH larger than the ones produced by OS X, and on
OS X the text was selectable and with a simple contextual menu gave you
options for looking up terms, word counts, or whatever else you added to the
text services of OS X.

Here is an example: <https://youtu.be/_J4PppWroWY>

There are a number of solutions... I have not used these, but found them
with a quick search:

Crazy troll talk.

All my scans get uploaded to vsftp ftp server on my Ubuntu
desktop PC from multi-page scanner as full colour jpg.

I plonk it into Libreoffice and job done.

I can export as pdf if I want.

I can insert dozens of high definition .jpg
into Libreoffice and it doesn't blink.
Still starts up in 1 second.

Must be that Linux superiority speed thing
doing all that talking again ;)


Hmmm... an idea brewing :)

Thing to do is write a python daemon to upload
all the files from ftp server to apache web server.
There a web app in php and MySQL can be used 
present the scans as thumbs. (Click on thumb to get
the full size jpg.) Then from there
to sort the scans into neat categories such as invoices, statements,
bills, certs, correspondence, brochures, reminders etc.

Easy to shred the paper then and make the office
more electronic and paperless. And make the paperwork
instantly accessible. I seen a bank use such
a system but it was seriously stingy for the storage
allotted for each scan (which was intentionally low resolution).
With 6TB disks, I doubt it will fill
with full colour scan papers in a lifetime :)

Yo mean the LibreOffice crapware can reduce exported PDF filesize as much as Acrobat does, with scanned images?

You are a *fscking* pdf illiterate appile/microshaft troll
selling microshit appile shiiiteware.

You were already told the image is ftp'd as a jpg which
is compressed already. (The compression and dpi is set in the scanner.)

So why is your appile microshit shiiiteware shrinking file
sizes and loosing image quality?
That is a negative selling point in the world of 6TB disks
for shiiiteware made by appile and microshit.

What the fuck?

Am I to assume that you have scanned documents (invoices, bills, etc.)
as JPEG files?

Ha, ha, ha, ha, ha, ha!

That must NEVER be done!  Never!

JPEG compression uses the discrete Fourier transform (DCT) on 
segmented image block elements and then discards the high frequency 
components.

On ordinary images, like photographs, this can work very well.

But on text documents, the sharp edges between text and background
represent points of discontinuity, and this will generate severe
ringing artifacts with JPEG compression.

Ha, ha, ha, ha, ha, ha, ha, ha, ha!

I've seen it all many times before.  Very few know what the
fuck they are doing when it comes to image processing.

It doesn't matter.  For text material use JBIG or DejaVu
compression.  NEVER use JPEG.  NEVER.

Don't argue with me.  Just don't ever do it.

If you can persuade my dog jpg is bad, then I agree.

In the mean time I'm using scanned jpgs and it works fine thanks.

I am totally agnosticalized on this.
If pngs or gifs work any best, I use that.

Adobe pretty much owns the professional graphics industry. Gimp is a 
great program and for the typical end user there are many programs one 
can use to manipulate graphics and not require a college degree to use. 

Manipulating graphics files via the command line is so 90's.
Include that on your CV and it will be put in the dinosaur reject pile.

The graphics industry is FAR from being professional.

Nearly every person that I encounter who works in professional
graphics or printing is a total dumb fuck, with only minimal
knowledge about imaging fundamentals.

It's a sorry state of affairs, but that's why they all cling
to Adobe products.

But then again, most "professional" image processing tasks are
little more than rote and formulary procedures that could be 
accomplished by anyone (even a fucking machine or a trained
monkey).

There is no fucking way that any meaningful work can be done
in the field of image processing without a great deal of
background knowledge.  Software can take a dummy only so far.

I run into this as well. I totally agree. I've been doing this for over
11 years now and I have met exactly one competent artist. That's no
joke.

They don't even use them correctly. They seem to have no idea how to
deal with the press and design for the screen only.

Big fucking deal.  It's like claiming that one is a good driver.

All he does, like a little schoolboy, is cut and paste the heads
of ugly bimbos onto the bodies of beautiful women.

Photoshop is for simpletons, so congratulations on your illusory,
or rather hallucinatory, accomplishment.

Being that's pretty much all you've done all throughout almost every day (with a few lapses for surgery, jail, etc.) for the last dozen or so years, why would anyone believe his suggestion is wrong? 

And the best part? You provided the "proof"  ;)
