DPI settings and OCR recognition

I am attempting to make a catalog of ours searchable. But
Adobe keeps throwing an alert that OCR cannot scan the page because
the image resolution is below 72dpi.
I created these PDFs using the Adobe PDF print option via
AutoCAD, with a DPI setting in the print set up of 300dpi. But
Adobe continues to say the DPI setting is below 72. Is there a way
for me to change the DPI setting of an existing PDF, or a better
way to influence the DPI setting of a new PDF? And on top of that,
is there a way to check the DPI setting of a PDF?

If you are using the PDF Maker in AutoCad it should already
make a text searchable file. IOW, it should be vector already. You
shouldn't need to OCR it to make it searchable. I believe in
AutoCad that there is an option to render text as text -- not
plotter text-- so you might look for that.

Linux: Firefox, DPI, fontsizes and hinting -- unuseable

Gentoo and Arch Linux. I have a small high-res screen. I'm using 120DPI as a system default. Works excellent for everything except Firefox (3.6 or 4.x) which ignores my DPI and uses 96. OK, I can use nosquint and enlarge everything 125% but it solves my problems less then partially. I'm using quite subtle fontconfig settings -- different hintings for different font sizes. Good settings for everything else (hintfull with no autohinter) make Firefox to be unusable (letters are much too thin -- thinner than a hair). Setting hinting to hintslight makes Firefox work acceptable but everything else is ugly. the problem is that 10pt for everything else is not 10pt for Firefox.
There would be just a simple solution: could the hell Firefox use correct DPI settings and display 12pt as 12pt, 10pt as 10pt? Is there any way to force it?

Increase the String pref layout.css.devPixelsPerPx from 1.0 to 2.0 in 0.1 steps to see what works best.
In current Firefox versions this pref is a String value parsed to a float and allows to fine tune the dimensions of all elements (user interface and web pages) more precisely.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.

'page size' and OCR

Is there any way to shrink the 'page size' of a PDF? I have a couple of very high-res PDF documents of 17th C books that I would like to run OCR on, but I get an error message that 'page size' is greater than 45 in. The original documents would have maybe 12in by 9in. I have the full CS5 suite, so I could use other applications if that is what is required. Thanks.

Go to the AdminUI ( http://<servername>:<port>/adminui ), and to Services, PDF Generator. Pick File Type Settings, and click on the Standard entry. If you pop open the HTML to PDF section, you can edit the size, margins, orientation, headings and footers, site recursion, and pdf initial view settings. Save your settings as a new Filetype (you can make as many as you want), and pass the name the filetype as the second parameter to the call to the htmlToPDF method on the web service client. http://livedocs.adobe.com/livecycle/es/sdkHelp/programmer/javadoc/com/adobe/livecycle/g eneratepdf/client/GeneratePdfServiceClient.html I am unfamiliar with interacting directly with the web services via SOAP, so if you are not using the pre-built GeneratePdfServiceClient supplied by Adobe and this information does not solve your issue you will need to see if anybody else can help. I imagine that there is a similar String parameter where you place the Filetype name defined in the AdminUI. (edit: I should mention, the GeneratePdf service is a part of PDF Generator ES, not Output ES, so you may have better luck in the general Livecycle ES forum)

Xorg.conf DPI settings VS. fonts DPI settings - Confusing!

I honestly have to admit, that I don't get it. Having a ThinkPad T42p with a 1600x1200 LCD with the visible dimensions of 304 x 228 mm, I have set that in xorg.conf ("DisplaySize 304 228"), which results in Xorg setting up 133x133 DPI on start (without specifying this DisplaySize setting, it defaults to 75x75 DPI).
133 DPI results in fonts displayed way too large, although I remember WinXP (which came preinstalled with this laptop) setting 133 DPI as well, which also gave large fonts, but not that large as seen with Xorg.
I am now using KDE (specifically funkyou's KDEMOD), and I have set "Fixed DPI: 96 DPI" in font-settings, which means, text is displayed in a reasonable size with 96 DPI, but Xorg is still set to 133 DPI:
$ xdpyinfo | grep res
resolution: 133x133 dots per inch
I really don't understand this font vs. Xorg DPI setting. How does this fit together?
Why are fonts shown way too large at 133 DPI, if that's the correct DPI setting for my screen size & resolution?

Why does it need to scale properly, if Xorg should already have set DPI to the correct value calculated from the display size?
How did you determine, that 100 DPI is the correct fonts-DPI-setting for your display?
This is just weird, because setting the DPI setting for fonts does not influence the DPI setting of the X server (that's what I mentioned above, selected "Fixed DPI: 96" in KDE's font-settings, and xdpyinfo still reports 133 DPI).
Concerning my LCD, 133 DPI seems reasonable for my 15" laptop-display with relatively high native resolution of 1600x1200, so the Xorg setting surely is correct. But why do I then need to set 96 DPI for fonts to be displayed in a proper size?
Even more confusing is, that the settings for the ATI Radeon open-source-driver offer even more options concering DPI:
#Option "MergedDPI" # [<str>]
#Option "ConstantDPI" # [<bool>]
As seen, I have not enabled these, but that makes altogether 4 different settings for influencing DPI.
Fact is, 96 DPI in KDE's fonts-settings seems to lead to the desired result, although that value should not be the proper one for my display-size & resolution, as well as I have no idea, what the X server resolution (133x134 DPI) is all about, especially because it does not seem to be of any importance if font-settings are forced to a different DPI setting (which means, it does not seem to matter, if the X server resolution is set to 75x75, 96x96 or 133x133 DPI, as long as the option for force fonts at 96 DPI is selected in KDE's fonts-settings).

hi,
i've upgraded my iphone 6 to 8.3 and i have problem.
microphone works well on phone calls and vocal note, but i can't use siri and vocal recognition on sms text.

Where do I change the dpi settings for creating a jpg in Bridge CS5?

I upload jpgs to an online site to be viewed in a browser. I've been using Bridge CS5 to batch process the jpgs from high quality pdfs.The settings I see when I do the settings to create the jpgs will only give me Maximum settings and the option to set it on 12 but when I open the jpg that's created in Photoshop, it's still 72. I would like to have at least a 150 dpi setting. I've searched and can't find any help online. What am I doing wrong, or isn't there any place to give me the option to change the settings to a higher dpi in Bridge? If this isn't possible, what do you suggest to make the process go faster? I'm using the Adobe CS5 programs.
Thanks in advance for any help.

"Maximum" and "12" usually refer to compression (influencing image quality and jpeg file size in bytes); and as Curt wrote, dpi is meaningless for display by and viewing in web browsers. (It could be a different matter if you are uploading the jpeg files for someone to download from the web to print.)
What are the sequence of steps that you and your batch processing take from Bridge?
You can use call Photoshop's Image Processor from Bridge to create the jpeg files (Tools > Photoshop > Image Processor). In the Image Processor you can set jpeg compression, pixel dimensions if desired, also convert to sRGB (good idea for web display). In my experience the image processor leaves unchanged whatever dpi is set in the source file; or, if none there as might be for a pdf, it will set the dpi value in your New Document Preset Print Resolution (from your Photoshop Units & Rulers preferences).

How do you change the dpi settings in iPhoto

How do you change the dpi settings in iPhoto

Short answer: the dpi is set when you decide what size you're printing at.
Long Answer: Dpi means nothing in the digital world of your computer. There are no "inches" to have "dots per..." Size is measured in pixels. That's the same on your camera. It doesn't take 10 x 8 or 6 x 4 shots. It takes shots measured in megapixels. For instance 4,000 x 3,000 is a 12 megapixel camera.
Using that example, that shot from that camera has 12 million pixels. So that's how many "Dots" there are. To decide the ratio of dots per inch, you now need to decide the "inches" part. And that's printing. Print at 10 x 8 and the dpi will be 4,000/10 or about 400 dpi. At 6 x 4 then it's 4,000/6 or 660 dpi. Work the other way: Print at 300 dpi and the resulting image will be about 13 inches on the longer side.
So, your photo as a fixed number of pixels. Changing the dimensions of the print will vary the dpi, changing the dpi will vary the dimensions of the print.

Xorg DPI settings won't save

Following the wiki, I decided to check if my DPI settings were correct, and fix them if they were not. These are the results I'm getting (full commands typed out for clarity):
First, without any configuration, the screen settings:
$ xinit /usr/bin/awesome -- :0
$ xdpyinfo | grep -B2 resolution
screen #0:
dimensions: 1920x1080 pixels (508x285 millimeters)
resolution: 96x96 dots per inch
This is wrong. Altering the commandline -dpi parameter results in the following:
xinit /usr/bin/awesome -- :0 -dpi 165
$ xdpyinfo | grep -B2 resolution
screen #0:
dimensions: 1920x1080 pixels (295x166 millimeters)
resolution: 165x165 dots per inch
This is right. For a more permanent solution one might alter xorg.conf settings, which I did:
/etc/X11/xorg.conf.d/10-dpi.conf
Section "Monitor"
Identifier "Monitor0"
DisplaySize 295 166
EndSection
However, it results the default 96x96 DPI, as you saw in the first code snippet. Furthermore, directly editing the DPI in xorg.conf such as this:
/etc/X11/xorg.conf.d/10-dpi.conf
Section "Monitor"
Identifier "Monitor0"
Option "DPI" "166 x 166"
EndSection
again results in the default 96x96 DPI.
Interestingly enough, if I deliberately put some bogus values into the config, Xorg complains about it and will not start up. So the config file IS being read, and there are apparently no errors in it. As well the other .conf files in the /etc/X11/xorg.conf.d/ directory is working (such as fonts.conf, which I am using to include /usr/share/font directories).
Why is the config not applying?

I think you can put it in .Xdefaults or .Xresources:

If this does infact work, then it didn't for me.

I looked this up also, and found that Xorg0.log gives different results then xdpyinfo :

resolution: 96x96 dots per inch
Xorg.0.log
[7232.286] (**) RADEON(0): Display dimensions: (520, 320) mm
[ 7232.286] (**) RADEON(0): DPI set to (93, 95)
No 90-monitor.conf file present, and Xorg.0.log only has 2 other lines with dpi , both about font paths.
So the question seems to be : which is right, Xorg.0.log or xdpyinfo ?
Interesting... The xdpyinfo one is correct (I can tell because of text sizes). However, when starting X without the -dpi argument it shows this:
[ 2194.180] (**) intel(0): DPI set to (174,171)
Not only is this the wrong DPI for my monitor, but it isn't the actual DPI that X is using. xdpyinfo correctly displays that the DPI is 96x96. However, if I launch X with the -dpi argument then Xorg.0.log will report the correct DPI (what I set it to). I really have no idea what's going on. I just wish my DPI settings would save!

Recommended DPI settings

Looking for some advice on DPI settings when exporting Nikon D200 RAW images to print photos, books, converting from RAW to JPEG etc.
At what point does it make no difference except file size?
Thanks.

DPI is used only to determine how large to print an image. In other words, if you have an image that's 3000 pixels wide and you set it to print at 300 dots per inch, it will print at 10 inches wide. If you have an image that's only 300 pixels wide and you print it at 300 dpi, it would only be 1 inch wide.
That is the only use of DPI. DPI does not determine an image's digital resolution. The number of pixels determines the image's resolution.
Generally speaking, if you're printing an image on paper you're better off with the largest image you can get.
At what point does it make no difference except file
size?
When you are exporting an image to be used in a digital presentation, such as on a web page or on TV, that's when you don't need to worry about DPI. That's when what only matters is the number of pixels in the image.
For example, if you export that image that's 300 pixels wide to display on a computer screen that's 1280 pixels wide, the image will take up about a quarter of the screen. And it doesn't matter at all what DPI setting you might have set.
You can download a PDF file of a chapter from one of my old Photoshop books that explains digital imaging resolution at http://www.seekpeace.com/viz/res/Resolution.pdf.

Upgrade scanner and OCR

We are expanding our OCR scanning of books for a client recently, and our current setup is too slow and unreliable when doing OCR (image to text)
1) Is there a good forum to discuss OCR on Macs somewhere? One with good and frequent participation?
2) We currently have the ReadIris Pro 11, and would like to consider buying a new, better scanner than the all-in-one HP printer-scanner we're using now. Does anyone have experience they'd like to share, or again - point me to a good forum
Thanks !

I am in the same position as you as you WD, I run Tiger/Readiris 11 and am having real trouble with it which I suspect are related to my settings and good Forums are just the place to get timely replies to problems.
My free Readiris worked well until I upgraded from Panther to Tiger and then I discovered I needed Pro 11 and this is when my troubles started
Getting support from Readiris is like waiting for paint to dry so for the moment I have just given up trying

Firefox Sync synchronizes DPI settings for Gmail

I set up Firefox Sync on a computer with a large monitor (a TV actuall) and I had to increase the DPI in the Gnome monitor settings in order for text to be readable on the large monitor. Now, using Firefox Sync on a laptop with a much smaller monitor, it appears the DPI settings have been synced for Gmail. Gmail somehow stores this information and Firefox has synced it. Is there a way to avoid this? Perhaps I should ask Google instead?

Do not delete the old account yet. sign up for an iCloud account if you haven't.
I understand .mac mail will still come through. Do not delete the old account yet.
You cannot use .mac or MobileMe as type of Account, you have to choose IMAP when setting up, otherwise Mail is hard coded to change imap.mail.me.com to mail.me.com & smtp.mail.me.com to smtp.me.com, no matter what you try to enter.
iCloud Mail setup, do not choose .mac or MobileMe as type, but choose IMAP...
On second step where it asks "Description", it has to be a unique name, but you can still use your email address.
IMAP (Incoming Mail Server) information:
          •          Server name: imap.mail.me.com
          •          SSL Required: Yes
          •          Port: 993
          •          Username: [email protected] (use your @me.com address from your iCloud account)
          •          Password: Your iCloud password
SMTP (outgoing mail server) information:
          •          Server name: smtp.mail.me.com
          •          SSL Required: Yes
          •          Port: 587
          •          SMTP Authentication Required: Yes
          •          Username: [email protected] (use your @me.com address from your iCloud account)
          •          Password: Your iCloud password
Also, you must upgrade your password to meet the new criteria: 8 characters, including upper and lower case and numbers. If you have an older password that does not meet these criteria, when you try to setup mail on your mac, using all of the IMAP criteria listed above, it will still give a server error message. Go to   http://appleid.apple.com         then follow directions to change your password, then go back to setting up your mail using the IMAP instructions above.
Thanks to dpepper...
