Inversing a BW negitive

I scan a BW negitive and saved it to my computer as a Jpeg or tiff File I open it up in Photoshop Elements 9 editor I go to Select at the top and click on All then go back to Select and click on inverse then a note comes up saying no pixcles where selected. Why? What am I doing wrong

Fast Inverse Square Root

I expect no replies to this thread - because there are no
answers, but I want to raise awareness of a faculty of other
languages that is missing in Flash that would really help 3D and
games to be built in Flash.
Below is an optimisation of the Quake 3 inverse square root
hack. What does it do? Well in games and 3D we use a lot of vector
math and that involves calculating normals. To calculate a normal
you divide a vector's parameters by it's length, the length you
obtain by pythagoras theorem. But of course division is slow - if
only there was a way we could get 1.0/Math.sqrt so we could just
multiply the vector and speed it up.
Which is what the code below does in Java / Processing. It
runs at the same speed as Math.sqrt, but for not having to divide,
that's still a massive speed increase.
But we can't do this in Flash because there isn't a way to
convert a Number/float into its integer-bits representation. Please
could everyone whinge at Adobe about this and give us access to a
very powerful tool. Even the guys working on Papervision are having
trouble with this issue.

that's just an implementation of newton's method for finding
the zeros of a differentiable function. for a given x whose inverse
sq rt you want to find, the function is:
f(y) = 1/(y*y) - x;
1. you can find the positive zero of f using newton's method.
2. you only need to consider values of x between 1 and 10
because you can rewrite x = 10^^E * m, where 1<=m<10.
3. the inverseRt(x) = 10^^(-E/2) * inverseRt(m)
4. you don't have to divide E by 2. you can use bitwise shift
to the right by 1.
5. you don't have to multiply 10^^(-E/2) by inverseRt(m): you
can use a decimal shift of inverseRt(m);
6. your left to find the positive zero of f(y) = 1/(y*y) - m,
1<=m<10.
and at this point i realized what, i believe, is a much
faster way to find inverse roots: use a look-up table.
you only need a table of inverse roots for numbers m,
1<m<=10.
for a given x = 10^^E*m = 10^^(e/2) *10^^(E-e/2)*m, where e
is the largest even integer less than or equal to E (if E is
positive, e is the greatest even integer less than or equal to E,
if E is negative), you need to look-up, at most, two inverse roots,
perform one multiplication and one decimal shift:
inverseRt(x) = 10^^(-e) * inverseRt(10) *inverseRt(m), if
E-e/2 = 1 and
inverseRt(x) = 10^^(-e) * inverseRt(m), if E-e/2 = 0.

How can I multiply all values of a 4-element array with all of its inverse values resulting to an array having all 16 products?

I'm quite new to LabVIEW (v.8.0) and I'm trying to figure out the easiest way to have a 4-element array multiplied by its inverse values resulting in a 16-element array
Array 1 values = 1, 2, 3, 4
Array 1 inverse values = 1, 0.5, 0.33, 0.25
Resulting array = (1, 0.5, 0.33, 0.25, 2, 1, 0.66, 0.5, 3, 1.5, 1, 0.75, 4, 2, 1.32, 1)
Any advice would be appreciated. Thanks!

Color inversion from iMac to TV

Hey,
My iMac desktop is extended to a Sony EX402 40" TV screen with this:
http://www.dealextreme.com/p/mini-di...er-1080p-34025
The problem is when im watching content on the TV it will go black after a couple of min and im getting color inversion. Its also a familiar problem for the Apple TV (scroll down for screenshots):
http://www.macstories.net/news/apple...d-philips-tvs/
Anyone knows a solution for this? I tried several HDMI ports on my TV but no luck. I could try to plug a different HDMI cable in or maybe the adapter is faulty
Im getting this on my SONY tv:
Anyone familiar with this?

Did you check Sony's support pages to see if there's a firmware update available for your TV? For example this which gives you version M8.717. (That link is to Sony UK. You better find the relevant page for your region.)
If that doesn't solve it then I'd suspect the HDMI converter.
My iMac is an older model, the late 2009 21.5" model. But I have it connected to a Sony V530 with no problems using a Kanex mini DisplayPort to HDMI converter (this one). Initially I had problems with the sound. I only got mono sound, but it turned out to be a problem with the HDMI socket on the TV. After I moved the cable to another socket, I got stereo sound.

Open Orders are negitive in ODS and Info cube

Hi,
Our ODS is getting data from sales order Item data and from ODS data is going to Info cube.
The problem is that: for few sales orders some open orders are deleting in R/3 but same records are reversing
the old records due to this in the ODS and info cube sales orders Quantity is negative but the orders are not negitive.
Could any one let me know how do we can ressolve it.

Animated gif looks inverse in Cap 3

I've done a search already at the forum and apparently if you
have more than 100 frames it will mess up. But this animated gif
has just 5 frames.
I import it as an animation, on the stage it looks perfect,
nice white background, all set to go. I then publish it and the
background appears all strange and inverse. Like i say it looks
fine on the stage , but when i publish it it messes up.
Any ideas ?
Regards

Hi Jean
I'm guessing that the palette solution offered by P_SJ
doesn't apply to FireWorks? I'm not a FireWorks user, so I'm really
not sure what that means. Other than perhaps referring to what I
know as a transparent background color.
Maybe try setting a background color to what your background
is in Captivate?

How to write an inverse routine for an info object at field level.

Hi All,
Our requirement is as follows:
Need to populate 0MAT_PLANT in a virtual provider. But during query performance it is like -
If someone were to add a filter to the BW query on 0MAT_PLANT, it would take the system awhile to search the APO database for that 18 CHAR material number because the data in APO is stored differently (40 CHARs). The point of the inverse routine is to convert the 18 CHAR to be 40 CHAR for those times when someone selects on 0MAT_PLANT. That way, the field types match and finding the data in APO is much quicker.
Hence if we need selection on the selection scree of the query for 0MAT_PLANT, we are trying for inverse routine which will convert 18 chars to 40 chars in the query level and the performance will be quicker.
See, 0MAT_PLANT is of 18 Char length. We are mapping it from ZMATNR in source which is of 40 chars. Thus initially in the field routine we will write a code to convert 0MAT_PLANT to 18 from 40.
Below is the code and the place we now we also need to write inverse routine to convert it to 40 from 18 chars.
*****Code to convert from 40 chars to 18******
*In APO if the material contains all integers values the material will
* come over as a 40 byte field. It needs to be shortened.
IF SOURCE_FIELDS-/BIC/ZMATNR CO '0123456789'.
    short_material = SOURCE_FIELDS-/BIC/ZMATNR+22(18).
*In APO if the material contains any character fields the material will
* not be zero filled and will be left alligned. Take the 1st 18 bytes.
ELSE.
    short_material = SOURCE_FIELDS-/BIC/ZMATNR(18).
ENDIF.
*add leading zeros to numeric only value
IF short_material CO '0123456789 '.
     w_num18 = short_material.
     short_material = w_num18.
ENDIF.
RESULT = short_material.
*$*$ end of routine -
***********here the iverse routine need to write************
*       Method invert_0MATERIAL
*     This subroutine needs to be implemented only for direct access
*       (for better performance) and for the Report/Report Interface
*       (drill through).
*       The inverse routine should transform a projection and
*       a selection for the target to a projection and a selection
*       for the source, respectively.
*       If the implementation remains empty all fields are filled and
*       all values are selected.
METHOD invert_0MATERIAL.
*$*$ begin of inverse routine - insert your code only below this line*-*... "insert your code here
Here you would write logic in 0MAT_PLANT to do the opposite of the above,
convert 18 back to 40 characters.
*$*$ end of inverse routine - insert your code only before this line *-*
The articulated form above in RED says that the subroutine i.e. the inverse routine is implemented for direct access and report to report interface.
Could anybody please help me or let me know any idea related to this.

Late 2013 Macbook Pro Retina with Turkish Q Keyboard, In windows 8.1 " and working inverse

I've late 2013 mb Pro with Turkish Q. I have installed windows 8.1 with bootcamp. But my buttons " and < working inverse. < button writes " and " writes <. If i use external apple q turkish keyboard no problem. In maverics evereything is ok. How can i solve?

Can I suggest the following articles, which are worth reviewing?
Boot Camp: About keyboards and key assignment for Microsoft Windows - Apple Support

Windows does require language packs to be installed, if you want the physical keyboard to match the on-screen keyboard.

How to rename with inverse rating in the filename?

This is a question about sorting and renaming.
I have a bunch of sports images in Lightroom that are all tagged with an appropriate rating or 1-5 stars. Because they are sports images, some are sequences of images taken at 8fps. I want the images to end up on my photo website (Smugmug) sorted first by rating, but for images of the same rating, I want them in chronological order (by date/time taken).
My challenge here is that I'm uploading them to a website that doesn't know how to sort by rating. In the past, I've renamed the images to include the rating as the first part of the filename, followed by the date/time and then I've sorted the gallery by descending filename. This successfully gets the images in rating order, but it does not get images with the same rating in the right order (in fact it gets them in reverse order).
Filenames would look like this:
Force97-5-20100926182129_7220.JPG.
"Force97" is the team name
The "5" is the star rating
The "20100926182129" is the date/time code
The "7220" is the original file number (useful at max fps when date/time codes are identical)
What I need to make these filenames sort properly is to be able to include the inverse rating rather than the actual rating so a five star image would get a filename with a 1, a four star image a 2, and so on. Then, I could sort by lowest filename first and everything would sort properly. Highest rated images would be first and within a given rating, the images would be in chronological order.
So, an image rated five starts would come out like this:
Force97-1-20100926182129_7220.JPG
With the rating of 5 converted to a 1, rating of 4 convert to a 2, rating of 3 as 3 and so on...
Does anyone have any idea how to do this in Lightroom? My only idea so far is to output them as shown here in Lightroom and then write a python script to parse out the rating from the filename, reverse all the rating numbers and rename everything again. I'd love to be able to do this within LR. Have I made myself clear what I'm trying to accomplish? Any ideas on how to solve this in LR?

If you can write a Python script, then the best way I think would be for
you to write a Lightroom export plugin instead, then rename as you see
fit...
Learning yet another language (Lua) and SDK is a possibility, but certainly not a quick way.

Question for inverse routine in the transformation for a virtual infocube

Hello,
I have a virtual infocube with it transformation and i want to know if there is a way to know in the inverse routine or in the start routine if in the query the user is selecting a filter value.
When the user want to select one value for a characteristic the transformation is executed in order to obtain the infoprovider values. In this moment the inverse routine is executed and i want to know if there is a way to identify when the user is making a drilldown or a filter.
In the start routine of the transformation i have an abap code with a very expensive time of execution to obtain some key figures values but i dont want that this abap code will be executed when the system executed the transformation to obtain the values for one characteristic in order to make a filter.
Thanks in advance for your help.
Best regards.
Ignacio

Hi Ashish,
Your document is very useful, in fact I used it to write my abap code, now Iu2019m getting the values of the query selection conditions, but what I need is after the report is showed in the first time.
When data in report is showed, user has the possibility to filter values for one characteristic. If the characteristic has the option for filter value selection during query execution equal to u201COnly Values in infoprovideru201D , the inverse routine is executed to obtain the values that are contained in the infoprovider and then the system show all the possible values. What I need is to identify this event, because in this case I donu2019t want to make some calculations in the transformation that are very expensive in time.
Thanks a lot for your information.
Best regards
Ignacio

Possible minor bug when selecting inverse with OpenGL enabled

When I make a selection (like a rectangle selection in the middle of the canvas) and then inverse it (Shift-Command-I), the marching ants only appear on the right and bottom of the canvas. This seems to occur only with OpenGL enabled. I haven't noticed any part of the layer missing or being affected by this when I cut/copy. Has anyone else noticed this?
Command-A or manually selecting the whole canvas results in marching ants on all sides.
Mac OS 10.5.6
CS4 11.0.1
2 GB RAM
256 MB VRAM

Thanks, hiding/revealing doesn't seem to change it, but changing the screen mode definitely does. It only seems to be a problem with a floating window (meaning that if I start with the floating window and hit F three times, it doesn't "refresh" to display the missing ants).

Color Managed Printing from LR 1.3.1 Inverse of Proper PS CS3 10.0.1 Behavior

Please excuse the length and detail of this post - I'm just trying to be very clear...
Also, it would be helpful if anyone having definitive information about this topic could please email me directly in addition to replying to this forum topic, in order that I might know a response is available sooner (I am new to this forum, and may not check it regularly). My direct email address is [email protected].
Bottom Line: Color managed printing using my own custom-generated profiles from LR 1.3.1 to my Epson 7600 (on Intel-based Mac OS X 10.5.2, but saw the same behavior with 10.5.1) using the current Epson 7600 Intel/10.5x-compatible driver (3.09) is broken, and appears to be doing the exact opposite (inverse) of what I would expect and what PS CS3 does properly.
I am color management experienced, and have been using my custom-generated EPSON 7600 profiles with reliable soft proofing and printing success in PS (both CS2 and now CS3) for some time now. I know how the EPSON printer driver should be set relative to PS/LR print settings to indicate desired function. Images exported from LR to PS and printed from PS using "Photoshop Manages Color" and proper printer driver settings ("No Color Adjustment") print perfectly, so it isn't the Intel-based Mac, the OS, the driver, the profile, or me -- it is LR behaving badly.
The specific behavior is that printing from LR using "Managed by Printer" with the EPSON driver's Color Management setting set properly to "Colorsync" prints a reasonable-looking print, about what you would expect for canned profiles from the manufacturer, and in fact identical to the results obtained printing the same image from PS using "Printer Manages Color". So far so good. Switching to my specific custom profiles in LR and printing with the driver's CM setting set properly to "No Color Adjustment" yields results that are clearly whacked, for both LR settings of "Perceptual" and "Relative CM". Just for completeness and out of curiosity, I tried printing from LR using the same profile (once for "Perceptual" and once more for "Relative CM") with the EPSON driver's CM setting set IMPROPERLY to "Colorsync", and the results were much more in line with what you would expect - I would almost say it was "correct" output. This is why I used the phrase "inverse of proper behavior" in the subject line of this topic. Going one step further, trying this same set of improper settings in PS (PS print settings set to "Photoshop Manages Color" with either Perceptual or Rel CM selected, but using "Colorsync" rather than "No Color Adjustment" in the Color Management pane of the EPSON printer driver) yields whacked results as you would expect that look identical to the whacked results obtained from LR using "proper" settings.
I said above that the improper settings from LR yielded results that I would almost say were correct. "Almost" because the benchmark results rendered by PS using proper settings are slightly different - both "better" and closer to each other - than those rendered by LR using the improper settings. The diffs between the Perceptual and Rel CM prints from LR using improper settings showed more marked differences in tone/contrast/saturation than the diffs observed between the Perceptual and Rel CM prints from PS using proper settings - the image itself was in-gamut enough that diffs between Perceptual and Rel CM in the proper PS prints were quite subtle. Even though the improper LR prints were slightly inferior to the proper PS prints, the improper LR prints were still within tolerances of what you might expect, and still better (in terms of color matching) than the "Managed by Printer" print from LR. At first guess, I would attribute this (the improper LR prints being inferior to the proper PS prints) to the CMM being used by LR being different from (inferior to) the CMM I have selected for use in PS (that being "Adobe (ACE)"). I can live with the LR CMM being slightly different from that use

(Here's the 2nd half of my post...)

What is at issue is trying to determine why LR is clearly behaving differently than PS in this well-understood area of functionality, all other variables being the same. (And, incidentally, why am I not seeing other posts raising these same questions?)
My "workaround" is to use "Managed by Printer" for printing rough prints from LR and to do all other printing from PS, especially given the noted diffs in CMM performance between LR and PS and the fact that printing from PS also supports using Photokit Sharpener for high-quality prints. Still it would be nice to understand why this is happening in LR and to be able to print "decent" prints directly from LR when it seemed appropriate.
Any insights or suggestions will be very much appreciated. Please remember to reply to my direct email address ([email protected]) in addition to your public reply to this forum.

Inverse color dodge not rendering in DWcs3

I have a blue-orange logo in inverse color dodge blending
mode on a gradient blue to dark blue background. It looks vibrant
and wonderful in FW; however, in both display and browser view in
looks identical to "normal" mode in Dw, i.e. dark and ugly. Is this
a DW bug; i.e. will the graphic look like it does in FW once
uploaded to the server? Or is there some other issue? First time
this has happened...
