Algorithm Help: Adjustable scale marks

I'm writing an app which displays a scale which is movable and resizable. It might display a range from 0.127 to 0.516, or 10,657 to 100,453.
1 - I know from the size of the font and window, number number of marks which I want drawn across that range. A value nominally between 10 and 15.
2 - I want the marks to be on sensible boundaries, 0.1, 0.25, 0.5 etc.
An example is that for a range 0.089 to 1.272 I'd want ticks 0.1, 0.2 ... 1.1, 1.2
Can anyone offer me any help with an algorithm to work out the ticks.
Thanks.
Dave.

I have always had to brute force this kind of thing. But I would try the following. Subtract the smaller number from the larger number and divide by the number of ticks. (or the number of ticks + 1, whichever works!) This gives you units per tick. Adjust the lower tick to be the nearest sensible number below your minimum.
This is tricky and there will be lots of special cases. If your ranges are in any way consistent, it might be best to use a bunch of canned ranges.

Presentation Variable in Scale Marker

I have a chart to show price evolution by month for a given year. It is driven by a PV (pvYear) from the prompt. When i added a scale marker to show average price for the year, however, I got this error msg - [nQSError: 10058] A general error has occurred. [nQSError: 27002] Near <@>: Syntax error [nQSError: 26012]
The SQL query for the scale marker is like this: select avg(price) saw_0, month saw_1 from SubjectArea where year=@{pvYear}
If I replace the '@{pvYear}' with 2010 or any year, the chart comes out fine.
Does it mean pv does not work with avg()?
Any help will be appreciated.

How to add a scale marker in PS CS4 standard? how to update PS extended?

I just installed PS CS4 standard. I found that I needed to have its extended one to add a scale marker in the microscope images.
Please let me know how to add a scale marker with PS CS4 starndard. Or, please let me know how to upgrade it to PS CS4 Extended.
Thanks,

Here's the instructions for Scale markers: Photoshop Help | Measurement (Photoshop Extended)
Now for the not so good news. You need Photoshop Extended, but the CS4 version is no longer sold.
You can either purchase CS6 Extended, Creative Suite 6 (which is over two years old and is no longer updated) or have latest Photoshop as part of the Creative Cloud Photography plan | Adobe Creative Cloud. Photoshop will always have the latest upgrades and versions and it is all "extended", no "standard" here. Run it on Mac or PC, and in many interface languages at no extra charge.
Hope you find something that will work for you.

Odd problem adjusting scale of rotoshape layer

Using Mocha I've rotoscoped my actor out of some footage in order to composite him on top of something else.
After pasting the shape data to his layer in AE, I'm happy with the roto but now I need to adjust the position and scale. Changing the position parameter in layer properties works fine, but when I adjust scale, the rotoshape starts to go haywire. As the layer size increases, the mask around the rotoshape gets left behind, despite being on the same layer. Then if I scrub forward in time, the position of the roto mask has gone back to its original place too. There are no keyframes on it, the only thing I have applied is the Mocha shape data. Am I doing something wrong, or is this a glitch?
Cheers.

It works as it should - all mocha data is treated as absolute based on the size of the mocha project and then relative to the AE comp, not the layer. You cannot simply scale later. Pre-compose, then scale or insert the mocha shapes as masks...

Color Picker scripting or Levels algorithm help

First question is: Does anyone know of a good explanation of the Levels algorithm as in how each setting affects a pixel in an image. If I change the midpoint of the levels, how would a specific pixel change in relation to that? I've been experimenting for hours and can't figure a common factor other than it seems to be a binary type relationship. The reason I ask this is because I'm trying to script something that will balance colors.
If that method isn't practical, I can go to the old fashioned trial and error method but this way also presents a roadblock to me. I set a color picker point and the script can obtain the values from that point exactly as it is in the Info panel. If I put a levels adjustment layer over top and adjust it, I now see the original color value and the adjusted color value in the Info panel, but I can't figure out how to obtain the adjusted value with a script. It still returns the original value. Does anyone know a way to obtain the adjusted value?
I hope I explained this right.

Thanks, Michael.
I'll have to look through that post on ps-scripts.com in more detail. That might be what I need.
This little snippet you wrote:
Michael L Hale wrote:
This thread may help with the levels part. http://ps-scripts.com/bb/viewtopic.php?t=2498
As for the adjustment layer you need to get the color twice. Once with the adjustment layer visible then again with it not visible.
var csColor = activeDocument.colorSamplers[0].color;
activeDocument.layers.getByName('Levels').visible = false;
var csColor2 = activeDocument.colorSamplers[0].color;
alert( csColor2.rgb.red + " : " + csColor.rgb.red );
doesn't get me the before and after values. Example: The point I selected has a red value of 226. I added a Levels adj layer on top and moved the midpoint so the red value at that point (adjusted) was 234. I ran your code and it came back with 225.591439688716 : 225.591439688716. It isn't showing the adjusted value of that point.

HT1338 Updated my imac from 10.6 to 10.8.2 recently. My iphoto logo in my Dock has been replaced with a transparent "question mark" and I can no longer access my iPhotos... please help!! Mark Howell

Why can I no longer find my iphotos? Updated from 10.6 to 10.8.2 recently... The iphoto logo in my dock has been replaced with a transparent, grey, question mark... why? How do I restore my iphotos? Searched for them in Finder, and in "search"... they appear as text only.. but no photos.. please help.. Mark

Have you verified that the iPhoto applications is not in the Applications folder or somewhere else on the hard drive?
To do so download and use Find Any File to search for "iPhoto.app" because FAF can search areas that Spotlight can't. If the application is somewhere else on the HD FAF will find it. However, I doubt that it will be there but it's worth a search.

PLEASE HELP- flashing question mark in folder

Hi everyone,
last night I was just on my macbook as usual and suddenly it froze, so I turned it off. When i went to turn it back on, all that appeared was a flashing question mark in a folder.
I have tried all the suggestions on this page http://docs.info.apple.com/article.html?artnum=58042 , but none of them worked because it didn't even recognise/find the harddrive in the disk utility section. I don't have apple care ($419 is a lot of money for a student!) but I only bought the macbook about 6 months ago, so it is still within warranty. What should I do now?
Any help is much much appreciated!
Melissa

Melissa,
I just had the same exact problem last night too. I called the apple technical service number and nothing they did helped because the hard drive wasn't found. I even got a fire wire cable and tried to hook my MacBook up to another Mac and tried the target disk mode hoping I could pull off data that I needed, but the other mac couldn't find the disk either. I'm kind of worried about losing some of my data. If you could let me know if you find any solution that would be awesome! I plan on going to the apple store this weekend to get it looked at.

IN DESPERATE NEED FOR HELP flashing question mark appears MacBook

Hello everyone, I got this White MacBook Mac OS X 10.4.11 yesturday I was updating limewire and iTunes, I was downloading some songs from Limewire when all of a sudden my macbook frozed. I was not able to do a thing. Not even minimizing nor quiting the app nor even opening another aplication, so I decided to shut it down by holding the power button until it shut down (about 8 secs). So I restart my macbook and I got this grey=blank screen whit a flashing question mark on it. I've tried EVERYTHING on this link http://support.apple.com/kb/TS1440?viewlocale=en_US even these one http://support.apple.com/kb/HT1533 and all I was able to accomplish, was to hold the mouse (/trackpad) button to eject a Cd, and while pressing Shift during startup (in order to start in Safe Boot mode) all I get is this lock image and this space to type a password. I've tried typing every password I know and I can't fix my macbook. Can anyone please help me out on this one?

It means certain system files needed for startup are corrupted. You will have to reinstall OS X. If your hard drive is unaffected you can try the following:
How to Perform an Archive and Install
An Archive and Install will NOT erase your hard drive, but you must have sufficient free space for a second OS X installation which could be from 3-9 GBs depending upon the version of OS X and selected installation options. The free space requirement is over and above normal free space requirements which should be at least 6-10 GBs. Read all the linked references carefully before proceeding.
1. Be sure to use Disk Utility first to repair the disk before performing the Archive and Install.
Repairing the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Do not proceed with an Archive and Install if DU reports errors it cannot fix. In that case use Disk Warrior and/or TechTool Pro to repair the hard drive. If neither can repair the drive, then you will have to erase the drive and reinstall from scratch.
3. Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When you reach the screen to select a destination drive click once on the destination drive then click on the Option button. Select the Archive and Install option. You have an option to preserve users and network preferences. Only select this option if you are sure you have no corrupted files in your user accounts. Otherwise leave this option unchecked. Click on the OK button and continue with the OS X Installation.
4. Upon completion of the Archive and Install you will have a Previous System Folder in the root directory. You should retain the PSF until you are sure you do not need to manually transfer any items from the PSF to your newly installed system.
5. After moving any items you want to keep from the PSF you should delete it. You can back it up if you prefer, but you must delete it from the hard drive.
6. You can now download a Combo Updater directly from Apple's download site to update your new system to the desired version as well as install any security or other updates. You can also do this using Software Update.

Need help adjusting colors in Photoshop (CS2)

I'm not a neither a novice nor a pro when it comes to Photoshop. (Just somewhere in-between) . . . So don't understand why I''m suddenly having problems with colors in my photos looking accurate on my canera, but almsot completely red and yellow in Photoshop. Initially though the camera was at fault, until I switched cameras and still had the same problem, so figured itmust be Photoshop.
Since Photoshop CS2 has all the features I need, I've never bothered to upgrade. . . which turned out to be a problem when I tried to follow the instructions for creating new adjustment layers. (Was OK until I reached the last step, when my menus were different than those in the guide.) Have spent most of the last 2 days trying to manipulate all the options under the Image Adjustment menu, but am running our of patience and luck.
The problem seems to have been increasing in recent weeks (or months), but this is the first time I've been absolutely stumped and unable to come up with a usable solution.

Thanks. But it looks like in all my frustration, I wasn't sure my original call for help had posted, so must have submitted the same question again.
But I just had a new thought on the problem. While reviewing a story I received from another website, I noticed that the photos attached to the article looked a lot like what I described in my message. It made me wonder if I have a software problem at all . . . or if it's the screen on my Mac that needs recalibration!
It only took 2 minutes to find a website that discussed it — with sample screens to help determine if that was what I'm dealing with. Since a screen supposedly showing a mix of numbered, grey boxes looked totally white to me and I could only see the white numbers on a screen that supposedly contained boxes in varying shades of black, I think I might be on the right track. Just not sure, since I had to reach the bottom of the page before spotting the pitch for a product that supposedly will recalibrate for me. I'm not sure I want to tackle recalibration on my own, but may call the Mac Geniuses at our local mall and see if my hunch is right . . .and if so, what they would charge to do it for me.
BTW, if it sounds like a calibration problem, do you think moving my computer from one desk top another (just 5 feet away) could have caused it? I'm not sure, since it wasn't on my mind at the time, but I think that's roughly when I first started to notice discrepancies in color.

Help with GRAPH Marker Design Tutorial

I am trying to create a custom marker design for a line chart (Using Illustrator CS3). I've followed all the steps in the HELP RESOURCE CENTER, but I can not get my marker to size any larger than the initial itty-bitty-square it creates. According to HELP, you can size your artwork larger than the initial marker square you copy and build the art over. That the design is scaled so that the backmost rectangle in the design is the same as the default square marker.
I've built it all in the proper order. But when I go to apply my new custom marker design, it is all sized DOWN to fit in the default square marker space.
Anyone out there with experience in customizing?

To add a detail: the marker box will always 6 pt square, no matter how big or small your designed marker is. So, to create a new marker design, simply draw the design as big or small as you want; position it in relation to the orig 6 pt square [which is always backmost].
I found this clarification with step-by-step instructions in this pdf document:
http://www.adobe.com/products/adobemag/archive/pdfs/9611qaai.pdf
When you save your marker design in the graph dialogue box, only the portion of your design that falls WITHIN the 6 pt square is previewed; but your entire design will show up when you apply it.
Hope this saves a bit of frustration!

BGP decision algorithm - help needed - stumped

Hello gurus! hoping for a BGP expert to chime in here. Im studying for my CCIE, and there is something in Jeff Doyle's Routing TCP/IP vol2 book that I just cant seem to figure out and its really stalling my understanding of the BGP path selection algorithm.
Its on pg 195, example 3-57, attached as an image in this post (Ive also attached the network diagram that this output refers to). Basically its an output of "show ip bgp" and whats stumping me is simply: for the aggregate route 192.168.192.0/21, why has this router selected as best (>) the one via next hop 192.168.1.254?? I would have thought based on the presence of the LocalPref = 100 on the 192.168.1.237 route that would have been selected. But apparently not! Heres a walk through of the path selection logic as i understand it:
1/WEIGHT: both 0, so skipped.
2/LOCAL_PREF: this is my problem, .237 should win, but ignoring for now...
3/ORIGINATED LOCALLY: neither are they are learnt from BGP peers, so skipping.
4/AS_PATH: both identical, AS100 only, so skipping
5/ORIGIN CODE: both are 'i' (IGP), both were created from "aggregate-address" statements on their originating routers downstream in AS100
6/MED: both empty, so skipping
7/PREFER [eBGP] over [confedBGP] over iBGP: so the .254 route apparently wins on this condition... which in isolation, i agree with (clearly the eBGP .254 route is better than the .237 iBGP candidate).
.... however what about step 2/LOCAL_PREF!?
looking forward to some expert guidance here to help me squash this one :)
thank in advance,

Also there is similar question on learning forums:
https://learningnetwork.cisco.com/thread/36845
From the forum:
"Locally Originated means that the local router is the one that generated the route with either a network statement, and aggregate statement, redistribution, or conditional route injection. It's not an attribute that is included in the UPDATE messge, instead it's just used by the local process as part of the path selection, where the router will prefer its own locally originated routes over someone else's origination of the same prefix."
Hopefully this will help.
BTW i am reading same book and too bad Mr. Doyle did not include full configs for all routers, as i am trying to simulate his scenarios sometimes it is not working as in his book, now i have issue on next page 197 why Orgin IGP is not taking precedence over Incomplete even if one is learned via EBGP and other over iBGP...driving me nuts.

Help: IMAQdx scale image size

HI all,
i'm new in LebVIEW and have a question.
Im using the functions of IMAQdx for a camera (XCD-U100 UXGA black&white).
Is it possible to take images with smaller size? I want to increase the frame-rate.
I can scale the image, after it was taken in max-size (1600 x 1200). But i want the camera to take in custom size, no in max-size.
I hope someone can help me

Hi NEOS,
i is possible to change the resolution in NI Measurement&Automation Explorer.
Go to Devices->IMAQdx Devices here you will find your Camera.
On the bottom of the MAX Window you will find Acquisition Attributes. Here you can change the Resolution of the cam.
Did this help?
Regards
Daniel
