Quickest way to find the darkest pixel in an image

I was wondering what the absolute fastest way to grab the darkest pixel(grayscale) in a picture. Or if anyone could give me any ideas on how one would go about making a fast dark pixel finder.

Is the image Greyscale or RGB?
Either way - you can access the data by getting the Raster
Raster r = image.getData()
Lookup the methods on Raster - you can access the data as one array.
If the image is RGB - you will have to convert it to a Greyscale value (you let the JVM do it by creating a new Greyscale image and drawing to it, or doing it yourself by access each one and performing the math)...
Lemme know...

Finding the Darkest Pixel in a BufferedImage

What is the best way to find the darkest pixel in a BufferedImage?

What is the best way to find the darkest pixel in a
BufferedImage?Define 'darkest'.
The simplest way to do it would be for each pixel to get the red, green and blue parts and take the max of those values as its brightness.

Set a threshold adjustment layer over your image. Drag the slider to the right until you see the last remaining white specks. These are where your brightest pixels are.

Hello Shanka,
If you are talking about Crystal Reports
I recommend to post this query to the [Crystal Reports Design|SAP Crystal Reports; forum.
This forum is dedicated to topics related to the creation and design of Crystal Report documents. This includes topics such as database connectivity, parameters and parameter prompting, report formulas, record selection formulas, charting, sorting, grouping, totaling, printing, and exporting but also installation and registering.
It is monitored by qualified technicians and you will get a faster response there.
Also, all Crystal Reports Design queries remain in one place and thus can be easily searched in one place.
Best regards,
Falk

Is there a way to find the serial number in these files so that I can reinstall the full version?

I had to restore from backup to a new hard drive, and only have part of my Adobe Photoshop installation. Is there a way to find the serial number in these files so that I can reinstall the full version? I have only part of the documentation so this is the best way I see to get the full version back.

Hello brad,
you did purchase your product from these firms like Amazon, so you didn't get a serial number, only a code with which you can request a serial number from Adobe. Please have a look at http://helpx.adobe.com/x-productkb/global/find-serial-number.html. (Start here: How did you purchase your product?)
The following part, so I just see at least, ceased to exist on my Adobe website, everything takes place in the link from above. I leave it as an info yet, it might still fit for you. For this purpose, please click your way through to your Adobe Store and find the button "Get Serial Number". Fill in the form and after a while you will get the real serial number.
Additionally you should have a look at Adobe's database, to see what's stored/saved about your accounts. Here you will find general infos about your Adobe Account.
On the other hand, if necessary and for further questions click through http://helpx.adobe.com/contact.html and if "open" please use the chat, I for may part had the best experiences. I quote from Adobe's employee Preran: The chat button is activated as soon as there is an agent available to help.

I have files that freeze my programs whenever I try to open ANY file. Is there a way to find the exact files causing the crash?

I have files that are freezing my programs (adobe; after effect and photoshop, as well as maxon cinema 4d). Whenever I try to import ANY file from within the program it doen't even let me select the file I need before freezing. I have moved all files off my desktop and into my dropbox, and it now allows me to import files/search for files on the desktop but NOT dropbox, once I go to dropbox it freezes again. I am assuming there are files within dropbox now that are crashing my programs. The problem is I have a lot of files in there and would like to remove the corrupt ones so that I can use my programs without freezing. Is there a way to find the exact files causing the crash?
This has happened a couple of times and each time I have to move all my files off my desktop, so there must be a type of file doing this, I just don't know what files they are.

ANY help would be greatly appreciated! It is making it really hard to get work done. THANKS!

This error sounds to me like you have/had BootCamp Windows installed and then removed, posible ?
If so (and even if not so), try restating your MBA while holding down the alt/option-key until you get to the Boot Selection Screen.
Choose to boot OSX.
Once in OSX go to System Preferences then Startup Volume and set your OSX to be the default.
Hope it helps

What is the quickest way to access the Settings on an iPad?

What is the quickest way to access the Settings on an iPad? (I mean, the usual cogwheel "app" called Settings)
In particular, I'm looking for a quicker way (or a more convenient one) to access it from an open application, than hitting the "home" button, possibly swiping the home pages, and tapping on it.
(I know, I know, I already placed it in the bottom bar, so I have it available from all pages...)
It would be great if I could cut another step or two. I mean, there are situations where I need to use the Settings app repeatedly. I wonder why it was not included in the iOS 7 swipe-from-bottom menu, while the "Camera" or "Countdown Timer / Clock" made the cut.
I know everybody will have a different opinion on what should be included in that menu, and choices have to be made, but still...
for example, on my Android smartphone the newer OS updates placed a shortcut to the settings app in the upper-right corner of the swipe-down menu, which is like the most prominent place you could place it in.
Anyway, do you know of one or more alternative ways to access the Settings app?
(Oh, and yeah, it just occurred to me that I can four-finger swipe it, if I have accessed it recently, but again if I access another app or two in between it will become at least as cumbersome as going through the home page).

Anyway, do you know of one or more alternative ways to access the Settings app?
Short answer, no. If you have a suggestion for future iOS functionality, use the feedback functionality found elsewhere on this site.

Best way to find the count of rows affected by a query

Hi All,
Is there a way to find the row count without actually executing the SQL statement? The count need not be accurate but it should be within acceptable limits. I know we can use 'explain plan' for this. But the value in plan_table.cardinality is way out of the actual expected count.
We would appreciate any pointers and/or suggestions.
Thanks
Edited by: user779842 on May 4, 2011 2:21 AM

maybe you can try this
How to get estimated number of rows of query without running actual query :
CREATE OR REPLACE FUNCTION get_rows_number (sql_select VARCHAR2, sql_id VARCHAR2) RETURN NUMBER AS
rows_number NUMBER;
BEGIN
EXECUTE IMMEDIATE
‘EXPLAIN PLAN SET STATEMENT_ID = ‘||CHR(39) || sql_id || CHR(39)||’ FOR ‘ || sql_select;
SELECT t.cardinality
INTO rows_number
FROM plan_table T
WHERE statement_id = sql_id AND ID = 0;
RETURN rows_number;
END;hope it helps!

You can run the patch with apply=n but this will let you to test the patch before applying it only.

Venugopal

Hi Venugopal,
If you add approvers using beekeeper for that resource AND that you use Outlook, you can see who is 'in charge' of that resource, ie the person that will hand over the keys to that room when you need them. That person is the only one who may be able to tell you who has booked the resource, you can then go and 'negociate' ;o)
In Zimbra (1.5.1.5) you can't see the contacts..

I have an iPad1 which I have reset and am preparing to give to a kid. I now find that I can't reinstall many apps as they now seem to require IOS 6 or greater. This is IOS 5 and can't be upgraded. Is there a way to find the older versions of the apps?

Is there a way to find the total "ON" time on my MacPro?

I was wondering if there was a way to find the total system "ON" time or usage time on my MacPro since I first purchased it?

I don't believe there is any recordation of that, but someone else may know better. There is, however, a record of how much time the computer has been in use since the last restart: open the Terminal application in the Utilities folder and at the prompt enter "uptime" (without quotes) and press RETURN.

InCopy workflow in InDesign: Is there a way to find the document in which an ICML file has NOT been checked IN again before saving the doc?

The situation:
We are working with the InCopy feature (checking in and checking out ICML files).
The problem:
I might have saved a document with an ICML file still checked out.
The question:
Is there a way to find out which document was saved with the ICML file still checked out?
or in other words:
Is there a way to find the document in which an ICML file has NOT been checked IN again before saving the doc?
Thanks for any help!

Hello Sumit Singh,
thank you for your answer and your reasonable recommendation. Unfortunately, this only works when the ICML content is used in one INDD file. In our case, we use ICML content in multiple docs (various manuals with the same safety instructions, warranties, adresses etc.).
So, is there a way to trace back where an ICML has been used?
Is it possible to find out in which document the ICML is still checked out?
