The values in pixels instead of %

Most of the books and threads talk to set the values are normally expressed in pixel values - but this option is not in Lightroom - only percentages. How about that - and in addition, the possibility of obtaining a value average over a large area - so it's easier to define levels of exposure of McBeth, graphics etc.

Hi David,

There are probably thousands of messages on this already. Pixel 8-bit values are the things to say when you have and in a defined color space. A pixel in Adobe RGB value will be a different color in sRGB (I know that you are aware of what is a laboratory). When you look at Lightroom you are looking at a record of ProPhotolike with a depth of 16 bits. The pixel values will not match with what you see on the screen vs. sRGB output.

Now a practical suggestion IMHO would be to ask a filtered histogram view menu that can emulate made spaces with the corresponding pixel values. Request the current display to turn into something else will not happen (again MHO).

As concerns re mechiers, have you looked at the DNG Profile Editor that can create a profile of camera on this basis?

  • View the description of the value of fields instead of the id value

    Hello.

    I created a table where the content of the GRAVITY field is a numeric value.
    Then I created a report (SQL query), where I have associated this field a LOV (1 = critical, 2 = major, 3 minor, cosmetic 4 =). I want to know hot to see the description of the value (display value, ex: minor) instead of the numeric value (back), when I submit the report. It's easier when I use a tabular form, but I don't understand how to sami, the same result when you use a normal report (cannot be changed).

    My APEX version is 3.1

    Thank you

    Hello Daniele,

    The title of 'report Attributes"for the report, click on change to the column. The value ' display as ' "display text (based on LOV, does not save the State) ' under the heading 'Tabular form Element' and select a named LOV or define a LOV under the heading"list of values ".

  • See the value of zero instead of "the value entered does not match the format of the field [].

    I use the simplified notation filed to perform subtraction on a budget form.

    They all have an excellent work and have no problem display a value of zero when it's a simple subtraction (value1-value2).

    However, on my last field I want to take the total income and subtract what I spent (approximately 40 fields) and get a balance zero.

    When I try to do it I get this warning "the value entered does not match the format of the field [].

    The calculation works fine and displays the correct value for all the foregoing ".» 01 "and displays negative numbers. 01 "and underneath as well (if I go on the budget), she just may not show a zero, which is my goal for this equal to zero each month.

    I tried to watch if the forms and have not found an answer that works even for my situation.


    Happy to post the form here, just do not know how to do it.

    Thanks in advance,

    The custom calculation script may be something like the following:

    Get the value of field of income, as a number

    var v1 = + getField("Income").value;

    Set up an array of domain names

    var aFieldsToSubtract =]

    "ThithesB,"

    ];

    Subtract the values in field

    for (var i = 0; i)< afieldstosubtract.length,="" i="" +="1)">

    v1-= + getField(aFieldsToSubtract[i]).value;

    }

    Set this field value by rounding the result to the nearest

    Event.Value = util.printf ("%.2f", v1);

    Do not think of this as a band-aid, think the correct way to perform the calculation, because it is. Note that "Thithes" may be a spelling error.

  • How to change the value of string clustered, to implement using the node value of property instead of writing directly on the flow of data or using the variable

    new to labview :-) and I have a problem when I want to change the value of a string in bunches, and I want to implement this using the node value of property instead of writing directly to the stream or by using the variable, enclosed is the picture.   No matter, I have change in cluster (control) or value of Popery out (indicator) cluster, the value (sensor 7) dataflow keeps unchanged even I gave the new value by value of property node. Thank you to give me some advice about this.

    Hi GerdW

    Thanks a lot for your answer. The reason I'm stubbornly tring to break the flow of DATA is: we have a test system that have about 100 screws, they have a few connected flow, some of them will be unbundling a cluster dataflow chain to check the value in order to make the different cases.  Now I want to insert user event by changing the control and influential cases during run time.

    As I initially uses a global variable (to control cases) instead of unbundle string data flow, it works well.  But then, I found there are a lot of screws that are using the string unbundle.  One of the 'lazy' means, I tried is to change the value via the property node (because that way, I did not need to find all the places where using the unbundle string and replace them with the global variable), then I noticed a problem with "dataflow", the value in the stream of cluster in fact will not be changed by changing the value of the property node.

    I did a test with VI simple (like the picture in last post), and after reading your advice, I tell myself that I need to understand the concept of "DATAFLOW" in labview, it seems that my "lazy" way can not work in this scenario.

    I have attached the criterion VI here, have you furthur suggestions on what I can do in this case?

    Mant thanks!

  • Display the export value of the drop-down list instead of the element

    I'm showing the value to the export of a drop-down list instead of the selected option or the user selects BLACK, but the value of exports of BLK is actually displayed.  I can find many discussions on how to get the value of the exports and display it or use it to trigger another answer in another area and I can usually tweak my existing JavaScripts when I need something new, but I just can't wrap my head around this!

    This is my last attempt (failed)

    var f = this.getField ("eyes");

    If (event.value is 'Black - BLK')

    f.Value = "BLK".

    I use Acrobat PRO DC.

    Any help is appreciated,

    Thank you

    Xavier


    I've been doing this for a long time and have never heard of anyone who wants something like this, so it is interesting. Remove your current script and try the following script Format customized drop eyes:

    Custom drop-down list Format script

    Event.Value = event.target.getItemAt (event.target.currentValueIndices, true);

    This defines what is displayed in the drop-down list in the value of exports of the selected item. Select the 'Value selected to validate immediately' option to the drop-down list for smoother operation.

  • How to send the values in a column of "report" instead of a "part of the Page?

    Hello

    Here's my case: two pages A and B.
    A page is used to display each employee of a selected service.
    Page B is used to create / modify employees.

    I create a button page which redirects to page B.
    By default, page B is empty (from course to fill in the blanks to create a new employee).

    However, there are 2 values I want to send to page B (I want to fill in some blanks in advance): the service and the Manager ID ID (there is a Department Manager).
    -I managed with the service ID because it is a page element and in the "Action when click on the button" button I filled "Set these Items"-> agenda of Page B "with the values"-> about a Page A day.
    -I am confused with the ID of eating because it is not a page element, but a report column and there is nothing to do like I did for the service in the button ID to create.

    I'm a bit lost cause I don't know how transfer/send this value to the second page.

    Do you have any idea?

    Thanks again for your time!

  • The ID of the list of choices that appear in the reports, instead of the value in the choice list

    I changed a value of list of choices for installation of product field sale step by a single word to keep the original "Bought" in the lookup Id and the value of the select list was amended to replace purchased with "quotes".

    When I run a report the scene of product sales, the field in the report appears with the original 'bought', even if on the page of the product revenue in the field "City".

    Can someone tell to overcome this so that the report also displays this field with the city in the text, according to the recording?

    Robyn,

    I think that statement uses the ID so you can disable it and create a new value or write a CASE statement WHEN:

    BOX WHEN "FieldName" = "" THEN 'cited' OTHER 'FieldName' END

  • Cannot change PopUp LOV width and height in version 4.2.5.00.08. I change the values of 450 400 in the Popup list template values (Section of the window), but my function genList0_f07_$ _row (), retains the same settings. Is this a bug?

    Hello

    I use APEX 4.2.5.00.08 to my app.

    I have a region of reports, where I display a column set. A column is the column attribute "display as" the value 'Popup LOV (LOV based query).

    I press the button to retrieve the LOV, I get a popup of 450 x 400 pixels.

    I go to the side of the model and navigate to "Popup list of values of model", where I can see in the section 'Window' attributes 'Width' and 'Height' value 450 and 400. I edit them and save them and there is nothing going on. I'm sure that the template belongs to my selected theme.

    I saw in the HTML source code that is the called function:

    <!--


    function genList0_f07_$ _row)
    {
    w = open ("wwv_flow_utilities.gen_popup_list" +)

    I see that the values has not changed. I also connected and disconnected. I am inclined to believe that it is a bug of the APEX.

    The only solution I think is to replace this function, which is NOT ideal.

    Thank you

    The parameters are generated only, nothing you can do about it because it does not use the model for these properties of the couple. Other things work fine for example the names of button or title window etc. I guess that, Yes, it is a bug. It's still there in the apex 5 too, I checked. The default values of the template do not match, the value in the generated code is always 400/450. So I guess it's pretty much a wait on 5.1.

    Here's a fun hack to make it work well on your page (works in apex 5 too, because the code is always the same). Put this in the execute on loading of the page section:

    (function(){
      var _open = window.open;
      window.open = function(){
        if ( arguments[1] === "winLov" ) {
          arguments[2] = "Scrollbars=1,resizable=1,width=500,height=700";
        };
        return _open.apply(window, arguments);
      };
    })();
    

    Change the settings to your liking. This will replace the existing window.open call, which is what the popup lov use and replace it with our own code. It does not interfere with other things. As the name of the new window is always "winLov" for the popup lov, it is the argument that is checked.

    During the call to window.open to open a new window with the name "winLov", parameters are replaced with your own version of it. The window is called as usual, using the stored reference.

    Edit:

    Yes, do not use the trick of resizing. My hack can be a bit tedious, but it's much less invasive for the end user (see open, bam, resize. "Even gets funky on multiple monitors). Also, this thing in the popup lov template will affect each lov popup that you use in the application, which is much less interesting than my specific page code.

    Edit2:

    I did a little digging in the source code, and I don't know why it does not work. Popup lovs are actually equipped to deal with it. My guess is that the parameters are recovered only after that the lists were generated, causing the package variables global to use their default values instead of model parameters.
