Some additional info about the LR 4 Basic controls

Folks, there's been a lot of discussion about the new image adaptive controls in the PV 2012 Basic panel. A post on the Lightroom Journal provides some background. There's also a link to the research paper titled, Local Laplacian Filters: Edge-aware Image Processing with a Laplacian Pyramid. The paper was presented at SIGGRAPH 2011. Note, the paper is pretty high level.
So, rather than thinking the new controls somehow dumb down the image adjustments, I think it would be more accurate to conclude they are now very, very smart. Pretty deep stuff. I've met Sylvain Paris when I did an MIT visit arranged with Eric Chan (also from MIT). Pretty bright boys...I don't know the other authors of the paper.
So, PV 2012 in LR4 (and the next version of ACR) is pretty high tech...

Lee Jay...I gave you a helpful answer cause, well, it will be a good warning for people who want to download the SIGGRAPH paper and make some sort of sence of it.
I read it, more or less...the main takeaway is that LR4 is doing some pretty exotic calculations on the image to perform really optimized image adaptive adjustments...and it really boils down to being able to find and deal with edges and adjust zones of tone (as well as other potential filtering such as Clarity). At this point, this hasn't trickled down to image sharpening and noise reduction–yet. But the Basic panel adjustments in PV 2012 are really pretty darn cool.
P.S. I looked up Laplacian Operator and my eyes glazed over...

  • Can anyone give me some tech info about the camera on my Pre?

    I'm about to set off on a long, lightweight trip and plan to use the Pre as my only camera on this trip.  I have a few questions about the pre camera which I can't seem to find answers to on the phone itself:
    1.  Is there any way to set the 'picture quality' on the camera - ie, low-res / hi-res - or do I just get what I'm given.
    2.  How 'big' is the filesize of each picture going to be - in other words, how many will I get before my 8Gb pre is 'full'
    3.  Is there any way to zoom with the camera?  I think not, but thought I'd ask...
    4.  To get the pictures off the phone, I plan to send them as attached files with text messages or email, back to base.  Then I could delete them from the pre, to create space. Will this method attach only low quality versions of each picture, or will the original-quality picture be sent?
    Thanks for being here.

    Post relates to: Pre p100ueu (O2)

    In answer to your questions,
    1. No, there is no way to change the resolution.
    2. It depends on the picture you take. I have not seen a spec. on the default file size. I suspect they will be in the KB range.
    3. No, no way to zoom.
    4. When you send the picture it should not change the resolution.

  • Info about the RFC

    Hi,
    I have to work on RFC FM.  Can any body give me the info about the RFC? especially for Function module?
    Will give Reward points
    regards,Ram

    Hi
    RFC (Remote Function Call) is similar to the general SAP fun module: except that in the attributes you click the radio button: RFC enabled;
    and you will be passing an Import parameter DESTINATION to it.
    Other code and usage will be similar to any fun module;
    Have a look at any fun module in SE37 to understand better about the different components of Fun modules;
    Refer this link:
    http://help.sap.com/saphelp_nw04/helpdata/en/22/042518488911d189490000e829fbbd/frameset.htm
    Function Modules doc
    Function Modules;
    Check this matter.
    Function Modules are Global ABAP programs created by SAP for reusable purpose.they have IMPORT,EXPORT and TABLE parameters, and EXCEPTIONS to through when error occurs.
    You can create them from TCode SE37.
    Go through the following doc:
    Function modules are cross-program, reusable procedures that are organized into function groups, and whose functions are implemented between the statements FUNCTION and ENDFUNCTION. Function modules and their interfaces are created in the Function Builder.
    Function Module Interfaces
    The parameter interface of a function module is defined in the Function Builder. It includes the definition of interface parameters and the specification of exceptions that can be triggered by a function module. The Function Builder automatically generates comment lines below the FUNCTION statement in the source code of the function module, which represent the interface of the function module with the following syntax:
    Syntax
    ... [IMPORTING parameters]
    [EXPORTING parameters]
    [CHANGING parameters]
    [TABLES table_parameters]
    [{RAISING|EXCEPTIONS} exc1 exc2 ...]
    The syntax and semantics of IMPORTING, EXPORTING, CHANGING, RAISING, and EXCEPTIONS mainly correspond to the definition of method interfaces with [CLASS-]METHODS. The additional option of defining table parameters using TABLES is obsolete.
    Interface parameters
    The interface parameters are defined on the relevant tab pages in the Function Builder.
    IMPORTING parameters are input parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input parameter. The content of the actual parameter is passed to the input parameter when the call is made. The content of an input parameter for which 'pass by reference' is defined cannot be changed in the function module.
    EXPORTING parameters are output parameters. When the function module is called, a suitable actual parameter can be specified for every output parameter. The content of an output parameter that is defined for 'pass by value' is transferred to the actual parameter if the function module is completed without errors. An output parameter that is defined for pass by reference is not initialized when the function module is called.
    CHANGING parameters are input and output parameters. When the function module is called, a suitable actual parameter must be specified for every non-optional input or output parameter. When the function module is called, the content of the actual parameter is passed to the input/output parameter, and when the function module is completed, the content of the input/output parameter is passed to the actual parameter.
    TABLES parameters are table parameters. Table parameters are obsolete CHANGING parameters that are typed as standard tables with a header line. If an internal table without a header line or a table body is passed as an actual parameter to a formal parameter of this type, an empty local header line is generated in the function module. If an internal table with a header line is used as an actual parameter, both the table body and the header line are passed to the function module. Pass by value is not possible in formal parameters defined using TABLES. Formal parameters defined with TABLES can be replaced by formal parameters defined with CHANGING. A local work area can be created for the internal table in the function module by using the addition LIKE LINE OF itab of the DATA statement.
    Exceptions
    The exception of a function module are defined on the Exceptions tab page in the Function Builder. Here you can select exception classes to define whether class-based exceptions are declared or non-class-based exception are defined. Class-based exceptions are represented in the above syntax by RAISING, and non-class-based exceptions are represented by EXCEPTIONS.
    The addition RAISING is used to declare class-based exceptions that can be propagated from the function module to the caller. Exceptions in the categories CX_STATIC_CHECK and CX_DYNAMIC_CHECK must be explicitly declared, otherwise a propagation can lead to an interface violation. A violation of the interface leads to the treatable exception CX_SY_NO_HANDLER. Exceptions of the category CX_NO_CHECK are implicitly always declared. The declaration of exceptions of the category CX_STATIC_CHECK is statically checked in the syntax check. For exceptions of the category CX_DYNAMIC_CHECK, the check is not performed until runtime. In a function module in which class-based exceptions are declared with the RAISING addition, the statement CATCH SYSTEM-EXCEPTIONS cannot be used. Instead, the relevant treatable exceptions should be handled in a TRY control structure.
    The addition EXCEPTIONS is used to define a list of non-class-based exceptions that can be triggered in the function module using the statements RAISE or MESSAGE RAISING. Exceptions defined in this way - as with formal parameters - are bound to the function module and cannot be propagated. If an exception of this type is triggered in a function module, and no return value has been assigned to it with the homonymous addition EXCEPTIONS of the CALL FUNCTION statement when the call was made, this leads to a runtime error.
    Note
    For new developments after release 6.10, SAP recommends that you work with class-based exceptions that are independent of the function module.
    RFC is a technology which is used to access a functions (Modules) from
    the remote systems.
    If a function module is set as remote enabled which can be access from
    the remote system via RFC.Eg: U can access the Remote enabled function modules in ur VB,Webdynpro,Java,Visual composer program.
    A function module can be set as remote enabled by SE37->Go to ur FM->click the option Button "remote enabled".
    But Normal function modules can not accessd from the remote system.
    Good Example for RFC enabled function module is : BAPI(Business Application Programming Interface)
    Note: All BAPIs are Remote enabled but not all remote enabled function modules are BAPI.
    CALLING A FUNCTION MODULE:
    1)In U ABAP Editor --> Click "Patter" ---> Selection Option Button "Call Function"
    --> Write the Corresponding FM name --> Hit Enter
    2)The appropriate import ,export Parameters will be displayed in ur editor
    3)Pass the Values Here.

    Hi Neil,
    Thanks for your suggestion. I thought I tried all combinations of database, catalog and schema names and all different orders to connect, associate the connection and generate entities, but it seems I did not try this one. I did exactly what you suggest, except for the fact that I connected to the database before associating the connection to the project.
    It partially works now. I can generate Entities. Once I have generated an entity, all generated private member variables become red underlined, because table "null" for columns "xyz" could not be resolved. And the drop down box for columns in the JPA Details pane still doesn't get populated. The latter can be fixed by selecting the proper schema for the entity, which results in a @Table(schema="xyz") annotation. However, I expected this to be done automatically when the Entity was generated.
    The error about not being able to resolve the columns still exists. I tried to add a @Column(name="ASDF") annotation (because the columns names are all capital, while the member variables are lowercase), but that doesn't resolve the problem.
    I hope this gives you a clue to solve the problem!

    Hi,

    Emad Zedan,
    > I need some information about the Document Class, can

    The concept of the document class was introduced in Flash
    CS3. What it
    does is allow you to optionally associate a custom AS3 class
    with your FLA
    in the Flash authoring tool. Your document class effectively
    *becomes* the
    main timeline. This is your chance to influence the
    underlying behavior of
    the MovieClip or Sprite instance that serves as the
    foundation for your SWF.
    If you don't associate a custom document class with your
    FLA, the FLA is
    associated automatically with a default document class called
    MainTimeline,
    which extends MovieClip.

  • A little info about the iSync plugin for the N97

    Several 3rd party developers have confirmed that something is broken in the way the N97 communicates via the iSync plugin. Nokia has changed, incorrectly implemented, or out right made something wrong and a firmware upgrade is DRASTICALLY needed or a plugin will NEVER work. The problem started with Nokia and ends with Nokia. They need to fix the problem with the N97. The developers feel that unless Nokia fixes this problem there will never be a plugin for the N97. It is as simple as that.
    This is all the info that I have at the moment. For the time being the only way to sync your data is:
    1. Prepare all of your data the way you want on your phone and then us Ovi. This can be a problem too as Ovi is not that great and is not very stable.
    2. You can use Memotoo (www.memotoo.com) to sync your data via SyncML. I have used tried it and it works okay. Better than Ovi for sure but it costs.
    3. You can use The Missing Sync by Mark Space (www.markspace.com - currently testing). It does not use the same way to sync via iSync plugins. The Missing Sync sends a plugin to your phone instead. The syncing is very stable and works flawlessly. The only drawback is that the phone plugin is not exactly designed for the N97 and it requires that the N97 needs to be reboot sometimes to sync. Other than this, the operation is flawless and it appears that Mark Space will be able to fix this one problem faster than Nokia will be able to fix their phone.
    Hope this helps......

    Yes, once you have MfE, you can sync N97 to Google Calendar and Gmail Contact list. The Mac's iCal app can add the Google Calendar. For Address Book, there are two choices: Access Gmail Contact via LDAP, or do proper synchronization in iSync style (see http://lifehacker.com/393855/enable-google-contact-sync-without-an-iphoneipod-touch).
    MfE is not "installed" by default in the N97, but it is actually there. I need to credit someone on this forum for mentioning it, but I'm afraid I forgot who. The steps are basically thus:
    Basically go to the Menu -> App folder, look for Settings Wizard "Sett. wiz.". Try to setup an email account from there. Don't use your gmail account though (it seems like MfE tries to be smart when it recognizes some email domains and pre-selects some settings for you, but we need to be able to access some options to set on our own). Don't worry about this account, you can always delete it once MfE is configured. At some point of the setup, you will be asked what kind of server. Choose Mail for Exchange. This will trigger Mail for Exchange to be installed.
    Subsequently you will see your MfE folder populated with Mail for Exchange and other stuffs. Get into it and configure your Gmail. Some settings to note:
    Exchange server: m.google.com
    Secure connection: Yes
    Use default port: Yes
    Username: Your gmail username (just the name, no need the @gmail.com part)
    Password: For the gmail account
    Domain: gmail.com (I believe blank is also ok, but mine is current set as such)
    Make sure that synchronization is set for Contacts and Calendar only. Tasks must be disabled (it used to be because Google Calendar did not support Tasks, but even they do support Tasks now, it still breaks MfE). Email must be disabled.
    Done.
    I did have further trouble though. The sync keeps hanging and then eventually "Invalid Password" error (yah right, after sync halfway they realize my password is wrong... no, something else is mucked up). I eventually deleted my phone data, and re-sync it from Google again, and everything was fine.
    Once you've got your phone data on Google, you can search Google for other tips on pulling the data into Mac.
    Hope you have fun getting this to work. 

  • Need info about the parameter _FIX_CONTROL in a BW environment

    Hi ,
    I have done some research about the parameter FIXCONTROL and went through the SAP note 1165319.
    We have a task at hand where SAP has recommended a new value to be added to this parameter in a BW production environment.
    Now in the above note there are an entire set of values which this parameter can take up.
    I have understood to some extent that this has to do with this Fixes if case of any issues.
    last month we have upgraded the oracle version of the database from 10.2.0.2 to 10.2.0.4.
    Can anyone help me in understanding what this MergeFix is all about?
    I need to better understand this concept.
    Thank you.
    Regards,
    Hari Kishan.

    Hello,
    still not sure if I fully understood your question; but the recommended approach regarding patches is:
    1) Apply all the interim patches recommended by SAP. For Oracle 10.2.0.4 these will those from SAP note 1137346. The merge fix from SAP note also 1165319 is mentioneded there.
    And by the way, SAP note 1137346 is updated about once a month; new patches may be added, old ones may be removed. SAP recommends to follow accordingly; but if there aren't any problems, you might want to you keep your current state for a longer period.
    2) Read all the SAP notes mentioned there. You may have to do additional tasks like setting Oracle parameters, FIXCONTROL or others. The value you have to set now may or may not be mentioned in one of these notes, I can't know.
    3) If you encounter some problem, first search in SAP notes, or if necessary open a support call with SAP. You may then have to apply additional patches and set addtional values for FIXCONTROL.
    And yes, this way the list of required patches may become specific to each customer, as customer requirements are specific.
    But it would be difficult to find the exact list of needed patches in advance.
    I think a BW consultant who is familiar with Oracle installations will tell you something similar. One who is very experienced in your scenario might also be able to recommend additional patches in advance.

    Hi Prasanna,
    Thanks for the reply.
    Actually there are about 3 to 4 files which are of type .open and they have created long back.Are those files still getting populated.If we set the "hour to close all files" to 0 it should close the open files and create the new(fresh) files for the next day right?
    According to the documentation in help portal, "Files may be closed before reaching this limit(Max File Size), as all files are closed at the hour specified in the Hour in the day to close all files property."
    Then how come some old files are still getting populated?
    Midnight means wat time in particular? Plz explain
    About timestamp is it the time the file was created in some format?
    If anyone knows plz explain the format of timestamp

  • Error handling: Customizing error details: Info about the the path to the VI which has thrown the error

    Hi,
    I need a quick advice about how to display in the error cluster the information about the path and VI which has thrown an error.
    When I don't prepare my own error message, and the error is captured automatically, the information about the path, Vi name and calling VIs is presented automatically.
    When I prepare/define my own basic error cluster I have only what I define in the string part of the cluster. 
    How to cause tha apperance the path and VI name in my defined error message?

    MimiKLM wrote:
    You mean this link
    That's helpful too but,  I had read "When I prepare/define my own basic error cluster I have only what I define in the string part of the cluster" as you wanted to use a file to expose those custom error codes and ultimately ship them with your solution dynamically rather than statically
    The error ring will pick up any custom errors you define in the error file(s).  Including formatting!  this then populates the explain errors and error dialogs just like any error definition that ships with any LabVIEW component or toolkit.
    Certainly, an error ring can also STATICALLY define or re-define an error within the application instance the ring is called from.  Those Error Rings are quite flexible!

    B01: CRM Generation
    C71: CRM Connectivity
    B09: CRM Replication
    You find a documentation about the Integaration of R/3 and CRM.
