How to display a user defined symbol when using addLinearFeature

Hello

We display our geospatial data of database image on the browser.

With the help of MapViewer mv.addLinearFeature I am able to draw lines on it.
I created styles in MapBuilder for our symbols userdefined and added to the Mapviewerconfig file.


Now, according to our condition, we need to put our user defined symbols in the middle of the line when a line is drawn using addLinearFeature

For example like this:



-------------(::) -------------------

Suppose that (:) that is our symbol.


Please tell me how to do this.

You can use the marker (user-defined symbol) as a label for the line. Something like the theme/style definition of roads in the mvdemo example where the highway shield is a marker.
SQL > select styling_rules from user_sdo_themes, whose name = "THEME_DEMO_HIGHWAYS";

STYLING_RULES
---------------------------------------------------------------------------






SQL > select the definition of user_sdo_styles where name = 'M.SHIELD1';

DEFINITION
--------------------------------------------------------------------------------





SQL >
The content of ROUTEN (column/attribute) is displayed in the marker (m.shield1).

Is your different condition or something similar work?

If its for just displaying a marker (i.e. your symbol defined by the user who is the notice of user_sdo_styles of database) somewhere along the line then use a line style definition (see Appendix A of the guide):





This will display the marker M.IMAGE105_BW on 0.15th of the length of the line.
If you would like this marker repeated at fixed intervals (the length of the line subsequently 0.15) then use

    ADF7,
    the subject of the post has nothing to do with the question (for as far as I see it).
    As you can see the error message clearly comes from the procedure pl/sql you call the application module, works of groovy appeal method.

    We cannot decide what makes your service if you pass null as a parameter. You can check the settings before you proceed to the procedure or write the procedure in how it treats null parameters.

  • How to remove the user defined color chart

    Hello I use a mac and CS5.5, I just want to know how to remove user-defined shades.

    Please help me if you can.

    Thank you

    In the Finder, choose go > go to folder type in "~/Library" (without the quotes), it's the tilde key (the wavy line next to the number 1 on the keyboard), and then the anti-slash-library.

    This will open the library folder of the user for the Mac operating system.

    (With OS 10.6.8 or more you can simply access the disk hard/Users / [you] / library because the library folder is not hidden, unless you use Mac OS 10.7 or newer)

    Now, go to / Application Support/Adobe/Adobe Illustrator CS5.1/en_us/Swatches

    You will see the files defined by the user, if they have been saved to the default location. If they were not saved to the default location, you will have to search your hard drive for the file names.

  • Another one: display interactive\text logoff scripts when using PCOIP

    Hello

    In my view, there a few other posts on this topic in the forums. Some remained unanswered, some are a few years old, so I thought I would try again. We have applied GPO logoff script that displays a reminder when using PCOIP session disconnects before that the script has the ability to run visibly. RDP works, but we don't\cant RDP because it serves various limitations. I am aware of a 2011 indicating post is not possible on 4.5, since it is 2014, hoping that progress could have been made about this feature. See you soon!

    Fear not, there is no previous version of vs change in this regard. Except a few messages on the forums of communities that you mention, I don't think I've seen something official - you raise it using the feature request form or with a sales representative? Relying on interactive logoff scripts is usually not a good design for something like VDI - even if it were visible, if the customer is dislocated for any other reason, you would not be able to return to the session.
