How to set threshold level JPG images

Please I need help with setting the right threshold value for my images. I am new with Photoshop. I need to interpret images consisting of sand oil and water in a glass medium. I need to calculate in pixels the volume of each phase (oil and water) with time. I converted the image to threshold and by default the setting is 128 level. This gives a rather high pixel value for the black background. adjust to other levels like 70 makes the white image more. Does some know how I can determine the correct threshold level to reflect that in the original image?
Also how can set the threshold value to be the same for all the files (example 600 jpg files).
Thanks a lot

Also how can set the threshold value to be the same for all the files (example 600 jpg files).
Create an action and use batch processing or import your images as a sequence and treat it as a video in the timeline. The rest is unclear. For all intents and purposes setting a threshold is completely arbitrary and factors like the color of the sand or whatever can influence it since e.g. red sand will naturally accentuate the red channel more than green and blue. Come to think of it, your methodology is rather unscientific in the first place, but providing one of your images as a sample reference might help people to be able to advise...

How to Set up Print As Image Registry Default.

This is a response to the archived post at:
martin hrubes, "How to customize printing by registry - print as image" #, 6 Nov 2007 2:28 am
I was trying to find out how to set the "Print As Image" advanced setting to be enabled by default. Here is what I discovered through trial and error.
1. The setting is stored per user and per printer. (i.e. it has to be set for each printer for each user.)
2. The registry setting is stored in the following key:
[HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\8.0\General\cPrintAsImage]
3. In this key, each printer has a separate binary value named s0, s1, s2, etc. The number increments by 1 for each printer added. If you open the value data, you will see it contains the name of the printer encoded in hex. (ex. hex coded for \\Server\Printer1)
My recomendation is to open a pdf file in reader, go to File -> Print ->Select Desired Printer -> Click "Advanced" Options -> Enable "Print As Image" -> Click OK - Click OK again. Repeat for each printer you want to
change.
**NOTE** If you don't click OK both times (i.e. cancel the print dialog), the change will not be saved. You have to actually print something to the printer. If you don't want to print something, make sure the printer is offline or not accessible (unplug the network, usb, parallel, serial cable) first. Once the printer has been changed, it will keep the setting until to you change it.
After you have set-up all of the desired printers, open RegEdit and navigate to the above key. Right click on it, and export it. Note the file name and location you are saving to. Close RegEdit. "Edit" (Right Click) the file just exported ("Opening" the file will just import it back into the registry.). Once opened, highlight and copy the registry key and all of the registry values. Paste the key and values at the end of the file. In one of the keys change "HKEY_CURRENT_USER\" to "HKEY_USERS\.DEFAULT\". Save and exit the file.
When imported this file will enable the "Print As Image" setting for the currently logged in user plus add the setting to the default users profile so any new users to the machine will have it enabled by default also. However, it will not add it to any other user profiles that already exist on the computer. To do this, either use a login script for domain computers or add the reg file to the "All Users Startup" folder.
It would be nice to have a setting in the deployment custimazation wizard to handle this, but for now we're stuck with enabling it the hard way.

Yes Spyla, please see this link http://www.404techsupport.com/2008/09/09/make-adobe-reader-and-adobe-acrobat-use-print-as- image-setting-by-default-2/comment-page-1/#comment-3112.
Allan, many thanks for your post, it certainly helped point me in the right direction. what I found though is that you do not need to tick the print as image box at any point during the setting up of this. All you need to do is add the registry key for whichever version of Adobe you are using for this to work. So basically. what you are saying for each instance of Adobe is regardless of whether or not the print as image is selected, the registry key is saying always print as image for the printer as specified by the hex code. I have found that for network printers, you have to include the full path i.e. \\<servername>\<printername> e.g \\testserver\printer1 and convert all of that to hex. With later versions (9 up over), they have allowed for the string name of the printer so that it is just plain text which also makes life easier.
What I do is apply this registry entry via Group Policy on a per room basis so that we only ever need to add one printer to the list. you could do this globally by adding all printers sequentially using s0, s1, s2 or t0, t1, t2 etc depending on which version you are using. The screenshot shows the registry key for 1 printer for Adobe Reader 8.
The value data is the binary code for the actual full printer name
This works a treat.
Hope this helps
Thanks

C How to Set Isolation Level in the Connection String

How to Set Isolation Level in the Connection String using the "Microsoft OLE DB Provider for DB2 Version 4.0"?
We are trying to move from Crystal Reporting that run against a IBM DB2 database on a mainfram to SSRS reporting and we have downloaded the "Microsoft OLE DB Provider for DB2 Version 4.0" and then worked with the DB2 Administrator to create the
Packages. We only have access to use the "Read Uncommitted ("MSUR001") package. We were able to connect and pull data before he removed access to the other packages, but after setting access the Connection keeps trying to use
the 'Cursor Stability (MSCS001)" package. How do we change the Default to the "Read Uncommitted ("MSUR001") package??? Since it is keeps defaulting to the the other package
we can't connect to do it in the T-SQL query, it has to be set at the Connection String level.

Hi Dannyboy1263,
According to your description, you want to set the Transaction Isolation Level in Connection String. Right?
In Reporting Services, the Connection String for OLE DB Connection can only contains Provider, Data Source and Initial Catalog. There's no property for setting Transaction Isolation Level in the Connection String. Based on my knowledge, we can
only set the Transaction Isolation Level at Query level or set it by using code (C#, VB, Java...) to call the property of Connection. So unfortunately your requirement can't be achieved currently.
Reference:
OLE DB Connection Type (SSRS)
Data Connections, Data Sources, and Connection Strings in Reporting Services
If you have any question, please feel free to ask.
Best Regards,
Simon Hou

How to Set Input Levels with FirePod and GarageBand

Hello ....
I/ve got Garageband and my Firepod 8 channel interface working ... but I need some tips .. especially on the relationship of input levels between my Firepod and Garageband ....
When I am setting input levels for a recording ... where should the input level be on the track in Garageband? .... Is that volume setting only for playback and mixing? .... or is it for the input as well ...
Thank you ....

Where should the initial input levels be set? ... Would you use the loudest
part of the song to do this? ...
Yes, as loud as possible without lighting the FP's clip leds.
When I mix the final product ... and change the volumes on the different
tracks.. aren't you then changing the input levels?
No, you're changing the output levels.
can't you red line and overload the track?
Yes, that's why each track has a fader, so that you don't clip.
Is there a master ouput level indicator
Yes, right over the Master Volume slider.
I guess you can't just put each track as loud as you want ... correct?
As loud as you want without clipping.
I would strongly suggest doing some web searches on "Mixing and Mastering" to learn more about how to mix, there's a TON of info floating around the web.

How do I play back jpg images quickly

I created a series of jpg images as an animation project. I now have 600 jpg images and want to create an 18 second clip with them. When I imported them into Premiere Pro CS5.5, and then added them to my timeline they each play for 5 seconds. I need for them to play at .03 seconds each to create the 18 second clip. How do I change the length of time each is displayed in Premiere Pro CS5?

SSIS How to set Tolerance levels via parameters

Hi all
I am after some help as pretty new to SSIS. I need to write some validation requirements on data which needs to be in SSIS.
What I want to achieve is setting Tolerance levels on two fields.
Field A has a tolerance lvl of 0%
Field B has a tolerance lvl of 200%
Both the fields will need to update a status field if the tolerance rule is broken
These will need to be parametized as well.
Thanks in advance

How do I create a JPG image from a clip

I need to create a jpg image from a movie clip. Is making a freeze frame the same and creating a jpg?

A jpg image is saved by FCE in a new file, while a freeze frame in FCE is a still picture used for a sequence in a project, but not saved separately.
To make a jpg, position the playhead in the timeline on the frame you want to save and Export/Using QuickTime Conversion and select Format: Still Image.
You are asked for a file name.
To make a freeze frame, position the playhead in the timeline on the frame you want to reuse within the project and Modify/Make Freeze Frame. This leaves a new still in the viewer: you can drag it to the timeline, drag it to the browser, etc.. - However this does not create a separate file but stays embedded in the project where it is used.

How to set recording levels?

I am recording electric guitars using small amps and Shure 57s and 58s through an Alesis MultiMix 8 FW. I'm looking for advice on setting the levels between the gain and level controls on the mixer and the level controls in GB. Should I set GB levels high, (maxed), and control it with the mixer, or set the mixer just below clipping and adjust with GB. Any suggestions would be appreciated.

How to set the resolution of images when saving Book as HTML

How can I set a different resolution for images converted to *.GIF when I save a book as HTML? Why doesn't the conversion to JPG work?

Hi
I am running a stand-alone version of Framemaket 10.I try to convert a documentation with a lot of screenshots in it. Regardless of the settings on the Reference pages of the first document of the book, Framemaker converts all graphic files to *.gif, and these are downsized so much that they become illegible. I would like to have them converted to JPG, with little resolution loss, so they are still readable.
I think Robohelp is too expensive…

How to edit text in JPG image downloaded from Shutterstock? [was: help]

I downloaded a jpeg image from shutterstock.com to use for my baby shower invitation and was told that I would be able to erase the example text and add my own using adobe illustrator but having a hard time figuring this out. Please help.

daynam60128295 wrote:

You were mislead. Text in a flattened raster image (your JPEG) is essentially "burned in" and not editable or erasable in Illustrator. It is true that you could set type over (in front of) an image with Illustrator.
It may be possible to achieve the end result you want, but without seeing the image, it would be difficult to tell you how to proceed. Can you post a screenshot?

How to set tray's background image in the custom page layout?

Hi all,
I've developed custom page layout with custom iView tray implementation. I've applied my layout into my page and added some iViews. Those iViews are URL isolated so they are rendered as an iframe. My problem is that an iframe background containing iView content overcast my background image which I have set in my iView tray implementation. Is it possible to set transparent background for an iframe in this scenario?
I would be grateful for helpful answers.
Best Regards,
Michał M.

Hi Tamil,
That's right, I've already used layout tag library do develop custom tray design but my problem concerns iView's isolation method . URL isolation renders iView's content in an iframe which has its own background. I've read some articles about getting transparent iframes but I'm not sure how could I achive this in SAP EP? Is it possible?
Best Regards,
Michal M.
