Convert mouse position to image position

Using a zoomed IMAQ image in an image control, I want to recover the position of the mouse in the co-ords of the underlying image. LastMousePositionX (and Y) give the info I want but they are one click in the past and not the current position. Amazingly, there doesn't appear to be an equivalent CurrentMousePositionX. I can't seem to find the info I need to do the conversion manually. The mousedown event returns the current mouse position and I can get the position in the image container by subtracting off its left and top position. But to convert this to the image position I need to know both the zoom and where the images origin is relative to what is displayed. I can't seem to find that origin position in the list of property nodes. The only thing I can seem to come up with is to extract the info from teh image information string, but this seems like an incredibly poor way to extract such obvious information - espeically since the info must be calculated to put in the string anyway. Can anyone help with this?

Hi,
I am confused why you get the mouse position one click in the past because it seems to work ok for me. I've had to use four of the image properties to recreate the effect using the mousemove event, but this seems to give the same values as the Last Mouse Position property so I think it does what you want. I couldn't see an origin property so I did the conversion using the position given at the image center. I wanted to post a snippet here but I'm new to posting and couldn't seem to get it to work for the whole block diagram, so I'm using a screenshot instead. I hope this helps in some way.

Convertir un négatif en positif sur LR 5

Bonjour, existe-t-il un moyen de convertir un négatif en positif sur LR 5. J’ai effectué un shooting d’une pellicule Kodak TX-400, et je voudrais pouvoir travailler sur l’image inversée (positif, donc). Merci

On peut inverser la courbe de tonalité (Point Curve), il suffit de mettre lextremité gauche de la courbe tout en haut, à l'angle supérieur gauche, et l'extremité droite tout en bas. L'image est alors en positive, mais tous les curseurs de tonalité seron inversés, par example, pour reduire l'exposition il faut porter le curseur à droite et pas à gauche comme d'habitude.

Can I control an image position with Scripting?

hello --
i find myself doing a lot of repetitive tasks in keynote, such as creating dozens of slides with an image in a specific position (x-y position). is there a way to automate this using applescript or automator?
so far, i am able to create the empty slides with the images in a specified folder, but they always just get centered. it's a good start, but the next time suck is to position them by hand.
any ideas?
thanks in advance.

Hello,
It's not possible without the help of the GUI Scripting.
This implies that you should not use the mouse or the keyboard during the execution of the script, but it's better than doing it manually on several images.
You must enable the GUI Scripting by clicking the checkbox labeled "Enable access for assistive devices" in the Universal Access System Preference pane.
Here is the script : this script create a slide of each image (your selection in the Choose file dialog), and it set the position of the image in each added slide to (40, 60)
---------------------Beginning ot the Script
set tFiles to choose file of type "public.image" with multiple selections allowed
tell application "Keynote"
    activate
    tell front slideshow
        set nSlides to count slides
        make image slides paths tFiles without set titles
        set nSlides2 to count slides
        set firstTime to true
        if nSlides2 > nSlides then repeat with i from (nSlides + 1) to nSlides2
            show slide i
            my setImageposition(40, 60, firstTime) -- set image position to (40, 60)
            set firstTime to false
        end repeat
    end tell
    display dialog "Done"
end tell
on setImageposition(posX, posY, firstTime)
    tell application "System Events"
        tell process "Keynote"
            if firstTime then (* initialization so that the script works correctly.
                   Show the Inspector window, click on "Metrics" tab.
                   Set the View to "Slide Only" *)
                set frontmost to true
                delay 0.3
                click menu item "Slide Only" of menu "View" of menu bar item "View" of menu bar 1
                set inspectorWindow to missing value
                set tWindows to windows whose subrole is "AXFloatingWindow"
                repeat with i in tWindows
                    if exists radio group 1 of i then
                        set inspectorWindow to i
                        exit repeat
                    end if
                end repeat
                if inspectorWindow is missing value then
                    keystroke "i" using {option down, command down} -- Show Inspector
                    delay 0.2
                end if
                tell window 1 to if name is not "Metrics" then -- size and position
                    click radio button 6 of radio group 1 -- the "Metrics" tab
                    delay 0.2
                end if
            end if -- end initialization
            keystroke "a" using command down -- select image
            perform action "AXRaise" of window 1 -- set the focus to the Inspector window
            delay 0.1
            tell group 1 of window 1
                set focused of text field "X" to true -- left position
                delay 0.1
                keystroke ("" & posX & tab & posY & tab) -- set image position,
            end tell
        end tell
    end tell
end setImageposition
--------------------- End Script
Important : You must localize the titles (depending on the language used in your system) in these two lines:
click menu item "Slide Only" of menu "View" of menu bar item "View" of menu bar 1
tell window 1 to if name is not "Metrics" then -- size and position

Cannot Control Image Position in RoboHelp When Linking To FM Files

We are using TCS 3.5 on Windows XP Pro. It has taken a lot of work to get our mapping from FM to RH to work correctly, and we now remain with one outstanding task that I cannot figure out: controlling the position of images in the RoboHelp output.
The images appear arbitrarily justified left, center, or right in RoboHelp itself and in help outputs. I should also add that this is happening with both structured and unstructured FM files. Typically, the output I'm working with is WebHelp or WebHelp Pro.
I've turned to the "Object Properties" and "Anchored Frame" pods in FM looking for settings that might be contributing to this behavior, but have not found anything that appears to connect settings there with the image behavior in RH. In the structured FM files, I had some suspicions that complex if/else conditions controlling image position might somehow be contributing to this problem. But the conversion settings in RH don't allow those EDD rules to carry over.
I also turned to the "Conversion Settings" in RH and played with some of the options for "Images" there, unticking or ticking "Use Distiller to Generate Images" and "Do Not Regenerate Images."
Our online help now looks pretty clean, since all the styles are mapped, with the exception being these wonky images everywhere.
I would certainly like to determine the root cause of this behavior, because we're using this FM>RH workflow to create online help systems for hundreds of legacy FM documents that encompass thousands of such images. I want to fix this in the mapping and not touch the original images, if possible
However, if anyone has the answer regarding the best practice for generally controlling image behavior in structutured and unstructured FM to RH, I would be eager to learn these details as well.
Thanks in advance,
Douglas

I believe it is. And I have had the same problem with tables.
I made multiple posts about the images trying to describe it in different ways, but all I got were crickets chirping on the forums. I finally called Adobe technical support. Their initial reaction was to show me how image mapping did work correctly with freshly minted FM files and RH project. I had to draw them back into real world scenarios by giving them my source files to recreate the issue. At this point they admitted something was amiss, and one rep even slipped and said it was a “known issue.” They promised to get back to me with a resolution. But despite 4 additional attempts contacting them, and they now just ignore my e-mails.
I am very disappointed in the way Adobe has handled this matter, both from a development and a support standpoint. It would do all of us users a world of good if they admitted these flaws in their release notes, and offered possible workarounds. Maybe there is no workaround, in which case it explains why they don’t admit it? But beyond poor software development and bug fixes, I think it’s sad that they don’t follow up on support.
Adobe seems to assume that tables and images are going to carry over from FM to RH correctly, so you get no fine tune controls, like you do for character and paragraph mapping, and I think this is the crux of the problem.
I got those tables working in my projects just by dumb luck, but I still have no control over them. The images…they still represent a huge problem for our company. We invested an enormous amount of resources into a RH migration, hoping to continue to use FM. But now we have issues with no apparent resolution. It’s making us regret our decision and reconsider our initial considerations to move to MadCap Flare and/or a component content-management system.
If you have any luck making headway with the issue, I would love to know more.

Image positioning in a div, vertical and central alignment

Can any body help me with this please.
I have a row of logo images displayed across a page like this example working perfectly on my test site http://thewebsitedeveloper.co.nz/thinkRedTest/pattonNz/suppliersTemplateCombined.html
On the actual Business catalyst site the same code is not accepting the verticval alignment and is positioning the image at the top of the div. Seen here http://pattonnz.businesscatalyst.com/suppliers_NZ
Can anybody tell me why this is/how to fix it? I have Googled but found no BC specific fixes.
Here is the relevant html/css info.
HTML
<div class="logoBand">
   <div class="supplierBox">

Hey Liam (and anybody else with the same problem), I found a fix. By adding
a span tag just before the image I am able to get the effect I'm after in
Business catalyst. I don't really understand how it does it, but it works,
in all browsers too = I'm happy. Here it is working
http://pattonnz.businesscatalyst.com/suppliers_NZ
CSS
.logoBand {float:left; width:890px; height:100px; margin-bottom:30px;}
.supplierBox{float:left; width:211px; height:auto;}
.supplierLogo{float:left; width:211px; height:90px; line-height:90px; text-align:center;}
.helper {     display: inline-block;    height: 100%;    vertical-align: middle;}
.supplierLogo img{ vertical-align:middle;}

Loading pages in Div? & Image Positioning

Hi i have 2 questions but to save 2posts i will put them both here
First might i say i trully appreciate the help people give at this forum!! hope one day i can help to
Anyway this is my 1st question
i am getting use to Divs now but still learning
i have my page layout as follows: Div at top of page containing site banner> Div under this containing the site navigation> Then my div containter containing site content
So what i want to do is load all website content into the bottom Div but not have to reload the top 2 divs similar to frames basically... I just see it as more efficient if the user is not having to reload the flash buttons and banner for the website everytime a page is called upon and yes i know frames are crap out of date etc etc im not using frames... i just want to target a div
Some one suggested using SSI which i understand how this works sort of... but i know the alternative to what i want is just to set up a basic of how everypage is to look and use ssi + new content?
My other question is about image positioning this i know little about> is there a way in dream weaver to grab absolute control of a picture and position it were you want in design view? similar to changing the wrapping in MS word and just wacking the pic were u want it to go
alternatively or on the same suject that may not be possible but can u atleast layer image over image or position images over 2 divs?
or is there a good tutorial on doing these sorts of things in dreamweaver cs4
Thanks alot for any help given

CSS Captions on floated images (similar to word wrap)

You're wrong about efficiency because that's not how a web browser works. Once your images are loaded into the browser's cache, they remain there - available for instant use in the rest of your site pages. Efficiency comes from good site planning. Gimmicks do not a good site make.
Adobe removed Flash Buttons and Flash Text from CS4 for a reason. Use CSS styled text links or CSS Sprites instead.

OBIEE 11g Title view Image position

Hi All,
Is there any way to change the position of image in title view in OBIEE 11g.By, default the image is coming on the left side..In my report i wanna display on the right side..
Guys please help..
Regards

In order to achieve this, you will need a custom skin (you can modify the original file, but I would not suggest to do this!).
The controlling file for the GUI rendering with regards to the title view is in the msgdb. It's the /messages/standardviewtemplates.xml. Again: please follow the process to create a custom skin and put the modified standardviewtemplates.xml there.
Changes to be made are here:
Standard:
<WebMessage name="kuiTitleViewDisplay" translate="no">
<HTML>
    <table class="TitleTable" cellspacing="0" style="@{tableStyle}"
    width="100%">
      <sawm:if test="logo || title || help">
        <tr>
          <sawm:if name="logo">
            <td class="TitleLogo" style="@{logoStyle}" rowspan="4">
            <img border="0" src="
            <sawm:param name="logo" />" alt="
            <sawm:messageRef name="kmsgTitleViewLogo" />" title="
            <sawm:messageRef name="kmsgTitleViewLogo" />"/></td>
          </sawm:if>
          <sawm:if name="title">
            <td class="TitleCell" style="@{titleStyle}"
            title="@{desc}">
              <sawm:param name="title" />
            </td>
          </sawm:if>
          <sawm:if name="help">
            <td class="TitleHelp" align="right" rowspan="4">
              <a href="@{help}" target="_blank">
                <img border="0" alt="" src="fmap:Views/Help.gif" />
              </a>
            </td>
          </sawm:if>
        </tr>
      </sawm:if>
After changes:
<WebMessage name="kuiTitleViewDisplay" translate="no">
<HTML>
    <table class="TitleTable" cellspacing="0" style="@{tableStyle}"
    width="100%">
      <sawm:if test="logo || title || help">
        <tr>
          <sawm:if name="title">
            <td class="TitleCell" style="@{titleStyle}"
            title="@{desc}">
              <sawm:param name="title" />
            </td>
          </sawm:if>
          <sawm:if name="help">
            <td class="TitleHelp" align="right" rowspan="4">
              <a href="@{help}" target="_blank">
                <img border="0" alt="" src="fmap:Views/Help.gif" />
              </a>
            </td>
          </sawm:if>
          <sawm:if name="logo">
            <td class="TitleLogo" style="@{logoStyle}" rowspan="4">
            <img border="0" src="
            <sawm:param name="logo" />" alt="
            <sawm:messageRef name="kmsgTitleViewLogo" />" title="
            <sawm:messageRef name="kmsgTitleViewLogo" />"/></td>
          </sawm:if>
        </tr>
      </sawm:if>
Basically you switch around the order of Logo -> Title -> Help to Title -> Help -> Logo. This way you know what happens in the doce above and make it Title -> Logo -> Help if you want.
These changes are application-wide wherever the custom skin is used (or just applciation-wide full stop if you modify the original file).

Lightbox 2 -size & position of image

By default, the new image opens in the centre of the page and
is cropped to a default size. How can I adjust the code so that it
opens at a specific location and expands to specific size, please?
I want to use the code for single images of same size and to open
always at the same location..

thanks. they have a forum, named huddletogether, but that is
pretty well useless. Although same problem has been posted many
times, the developer and others have not replied.... Apparently,
the developer is TOO BUSY to attend to trivia like replying to
questions about his OWN product. Pretty poor... I say...Not
everyone wants the box to open in the centre of the page..:-((
Hence my post here, in hope that someone might have the solution?
UPDATE at 16.00gmt. I have played around with the code in the
lightbox.js file. Line 237 has a line :
this.lightbox.setStyle({ top: lightboxTop + 'px', left:
lightboxLeft + 'px' }).show();
I have added couple values, which position the image exactly
where I want it. As:
this.lightbox.setStyle({ top:160+ 'px',
left:(-100+lightboxLeft)+ 'px' }).show();
However, I am still looking for the code which gets the
image's dimensions.... Maybe, there is no such a thing, as the
enlarged images are always shown the same size; they are
increased/decreased to the default value...
Any ideas, please?
UPDATE: That's all sorted. But as a result, the 'close' and
'load' images are now showing far, far too big and in wrong
position...

Utility to adjust image position?

Does anyone know if there is a utility that can be used to fine tune the display image position (ie. horizontal/vertical position, rotation)?
I've noticed that the image on my iMac display is slightly off to the right -- in other words, there is more black border on the left than on the right. I was hoping there would be some simply adjustment similar to the built-in adjustment controls on some LCD monitors.
Thanks!

Not that I know of.
You can try the Apple genius bar at your local Apple store maybe they know how too.
I know in windows you can or if you have a external monitor but then you have to install that monitor's specific drivers / programs if they have some ??
There might be a program but you should not have to worry about stuff like this as that is why you payed too much for your Apple so it can be returned to them so they can replace it or fix it.
It can even be something stupid like the display driver and that then only will be fixed in Tiger 10.4.5 update that is free likely around the 22 feb or later.

Positioning an image in the same location on different projects? (CS5)

Hello,
Is there a way to position an image in the same location on multiple projects aside from trying to use the rulers? I can never get them to match up evenly. They're close, but there has to be a way to make it match perfectly.

If you have a few to do, you can create an action so it will speed up the process.
To create this action.
(With the document open)
Start a new recording
File - Place - select your logo (tiff, png, jpg etc)
This will put the logo into the center of your document, press enter to comfirm the selection.
Select - All (or ctrl/a)
Layer - Align Layers to Selection - Top Edges (or where ever you want)
Layer - Align Layers to Selection - Left Edges (or where ever you want)
Your logo is now in the top left of your document
Select the Move tool (v)
Now to put it exactly where you want use the cursor keys
One press of the cursor key = 1 pixel
Shift and cursor key = 10 pixels
Once you have the logo where you want ctrl/d to deselect then stop the recording.

Positioning an image in an AP element of an editable region

This is the current scenario:
<div id="graphix">
            <br>
                                    <br>
                                    <br>
                                    <br>
                                    <br>
                                    <br>
                                    <br>
                                    <br>
                                    <img src="../images/general/spv.jpg" alt="vidura" height="341" width="267" border="0">
            </div>
Is there an elegant CSS method of positioning the image instead of using <br>? I tried putting a <div> around the image to control its position. It seemed like a good idea but that utterly failed.
Any suggestions or should I just stick to the primitive but effective <br>? It at least works, not pretty but does the job.
Branko

Once you have one image in place the next one down will take its position according to margin-top: XXpx; (see inline css example below style="margin-top: 60px;")
<img src="image_1.jpg" width="600" height="450" />
<img src="image_2.jpg" style="margin-top: 60px;" width="600" height="450" />
EDIT: You'll probably need to use display: block as well (see below) if your container which holds the images is more than twice the width of the image. If you don't the images will just line up side-by-side until no more space is available at which point they will start another line.
<img src="image_1.jpg" width="300" height="220" />
<img src="image_2.jpg" style="margin-top: 60px; display: block;" width="300" height="220" />
<img src="image_3.jpg" style="margin-top: 80px; display: block;" width="300" height="220" />

Image positioning with table and css?

Hi please look at the following link to see my problem
http://www.stefanlesik.com/csg/traditional-designs.htm.
I am trying to position a list of photos with details of dimensions
and reference number below each. I have set up a table with 2
columns but I cannot position the images inside the cells
correctly. I've also tried adding an image style to each with
padding etc but this does not work. I'm sure there is a simple
solution. Any other comments about the design of the site would
also be very welcome. Thanks in advance

You need to add valign="top" to your cells in that table.
<td height="0" width="265" valign="top">
Also your first image is wrapped in a <p> tag. The
second is not. That is why you will see extra space at the top of
the first one. You can also delete all of the height="0" that you
have through out your code.

Shuffling Image Positions

If I have 20 images (cut jigsaw puzzle pieces) scattered around the top, sides and bottom of a stage, and want to shuffle their positions upon entering the frame (or using a button), what type of shuffle/swap array would I need to randomly swap their X Y positions? I've looked for examples in solitaire type games, but haven't found any so far.
Any help appreciated.

So far, I can, by adapting a script that I found, create an array of positions for the 20 pieces (currently named p1, p2, p3...p20), randomize the array and trace the output.
var positions:Array = [{x:28.85, y:21.85},{x:243.80, y:20.85},{x:450.80, y:17.85},{x:648.80, y:17.85},{x:850.30,y:17.85},{x:855.80,y:124.35},{x:852.80, y:269.35},{x:852.80, y:418.30},{x:855.80, y:597.30},{x:693.30, y:606.30},{x:604.80,y:612.30},{x:357.80,y:611.30},{x:194.80, y:608.30},{x:17.85, y:606.30},{x:853.30, y:491.30},{x:6.85, y:462.45},{x:10.85,y:216.50},{x:28.85,y:425.30},{x:236.80, y:609.45},{x:494.30, y:615.45}];
var len:int = positions.length;
var pos:int = 0;
for (var m:int = 0; m < len; m++)
   pos = int(Math.random() * positions.length);
   trace("Setting one clip to x: "+Object(positions[pos]).x+" and y: "+Object(positions[pos]).y);
   positions.splice(pos, 1);
What I need help with: even through I can set up a trace, I'm not sure how to now take the "traced" output and insert it into another array to position p1, p2, p3...p20?

Positioning multiple images at bottom of Div Tag

I want to position some images so they are side by side, at
the bottom of a div tag. So far the only way i've managed to do
this is by using a padding-top value. Is there a better way?
I also want these images to be centered horizontally.
Thanks

Are these cosmetic in use? Make them a single image
background.
#foo { background-position: center bottom;
background-repeat:no-repeat; }

Background Image Position Whole Numbers vs Decimals

Hi EA experts,
I'm using sprite sheets to create animations in Edge Animate CC and have run into a peculiar problem: Occasionally, when I am animating frame-to-frame and changing the background image position, the numbers I input (for example, -400) end up somehow being changed to a value a few decimal points off (such as -399.96). When playing the animation back, even this tiny fraction of a pixel difference ends up causing the sprites to shift and play back choppily. What's more frustrating still is that Edge Animate shows the X/Y values as the correct whole-numbers I inputed, until I click on them (see attached). Given the amount of animation I'm doing, now that I've found out this is the problem, I have maybe hundreds of X/Y values to correct.
The whole number I input is displayed...... until you click, and see that it's off a bit
Is there a way to easily correct this? Perhaps a way to make Edge Animate only accept whole numbers for background image position values?
Thanks,
-Adam

Whole numbers kick decimal butt.
Also, that's not how you calculate leap years. Just
an FYI.What is it? Leap year if %4 == 0 and %100 != 0?
I think... whatever, Google is your friend.
