Found the solution using MapImageGenerator

I am applying like this

on .qml:

function getImage() {
   mapImage.getImageMap(lat, lon, screenWidth);
}

attachedObjects: [
   StaticMapImage {
     id: mapImage
     onGetProperties: {
       staticMapImage.image = aPropertyMap.img;
     }
  }
]

ImageView {
   id: staticMapImage
   preferredWidth: screenWidth
   preferredHeight: 300
}

on StaticMapImage.cpp:

StaticMapImage::StaticMapImage(QObject *parent):
    QObject(parent)
    {

    }

void StaticMapImage::getImageMap(const double &aLatitude, const double &aLongitude, int width)
    {
    ViewProperties mapProperties;
    mapProperties.setLatitude(aLatitude);
    mapProperties.setLongitude(aLongitude);
    QRect windowRect(0,0, width, 300);
    mapProperties.setWindow(windowRect);
//  mapProperties.setAltitude(500);

    iMapImageGenerator = new MapImageGenerator(mapProperties);
    bool result = connect(iMapImageGenerator,
            SIGNAL(finished(bb::cascades::maps::MapImageGenerator *)),
            this, SLOT(imageFinished(bb::cascades::maps::MapImageGenerator *)));
    Q_ASSERT(result);
    Q_UNUSED(result);

    iMapImageGenerator->start();
    }

void StaticMapImage::imageFinished(bb::cascades::maps::MapImageGenerator *aMapImageGenerator)
    {
    bb::cascades::Image img(aMapImageGenerator->imageData());

    QDeclarativePropertyMap* propertyMap = new QDeclarativePropertyMap;
    propertyMap->insert("img",  QVariant(QVariant::fromValue(img)));
    setProperties(propertyMap);

//  delete iMapImageGenerator;
    }

QDeclarativePropertyMap *StaticMapImage::properties()
    {
    return iPropertyMap;
    }

void StaticMapImage::setProperties(QDeclarativePropertyMap *aPropertyMap)
    {
    iPropertyMap = aPropertyMap;
    emit getProperties(iPropertyMap);

    Several solutions. I advise to begin:

    You have your two visible photos the of in "basket" (area of the bottom of the screen). Choose the one that will serve as "background by double clicking on its icon. She apparaiit in the editing space. Now, click the second image basket of the in and drag on the edit box.  You have a preview of this new layer, ready to be resized, moved or such. Use the handles of the frame of this image pour what control do. When you post by clicking the green check mark, your new layer should appear in the layers of the screen Panel.

    You can adjust the dimensions etc. without loss of quality; This layer is UN 'smart object' as long as you don't choose "simplifier" (freeze) the layer which becomes a regular layer.

    Some operations on the layers cannot be carried out only after having simplified.

  • Adobe Stock-dubious Marketing? [How to get 10 free images without registering for Adobe Stock?]

    Recently signed up for a subscription of photography CC and was happy to see that I would be able to get 10 free Stock images.  But when you actually go to get your free images you said then you get 10 free images with a @29.00 month subscription to Adobe Stock. While in the fine print, it says that you can cancel at any time during the first month, it actually requires an account with your credit card.  Not impressed - if you get 10 free images why don't we just let users select 10 images free of charge without registration?  After all that you say it is that they are free

    MK

    Hello

    Thanks for your comments.  As you have seen, registration is required for the 30 days test where you get 10 frames.  There is no charge for the first month, and if you do not want to continue with the subscription, you can cancel during the first month.

  • How to get the background image to fill the browser and stay fixed in IE and Firefox?

    Basically what it says in the title. I came very close to achieve, but something comes to Moor in the html and css code...

    First of all, I use the latest version of Firefox and IE8 to test this situation.

    I used 2 sources of information to get this done: 1) http://css-tricks.com/perfect-full-page-background-image/ and ) 2 http://stackoverflow.com/questions/8958697/css3-background-size-cover-doesn ' t-make-image-co-ver-vertical


    In 1 case , the example of the called page CSS-Only Technique #1 gives the code that works almost perfectly for me, except that obviously I need to a background image, but the CSS provided ago obviously just for an image has fallen in the body of a page without taking account of any other content that may already be there. "The html code that I put on the page is simply < img class ="bg"src ="... / pictures/background_image.jpg "> "

    Of course, I used the CSS code in the example, less the last piece which is "@media screen" etc., which seems irrelevant to me. Of course by replacing the values according to the picture on my page.

    So what happened was that it worked almost as expected in both browsers (which means the image filled both browsers first as it should and also remained fixed when I zoomed in, inside or outside, in each case), except that the picture went on top of the current content that I already there precisely because there isn't a background in this 'technical '. (A note on the side of curious, is that the image didn't turn down content, I expected under normal circumstances, but he went right on top of it so she she hidden (like the z-index).)

    One thing that bothers me in this regard 'technical' is that if you click on view the demo just below the code provided, you will see on the example of work page (bottom of the forest), the image clearly works as a backdrop and the content is fortunately located on top! So I don't know if the person who provides the example was trying to deceive people or what! Or he got lazy and showed another page which did not use the exact code, he has provided. No matter.

    In any case this leaves me with only half-completed work, because I still need a background image that functions as the 'normal image' code provided.

    In 2 cases and on this page, the first example provided gives the CSS for clutter - namely the code in the html {...} part and shows also the same "normal image" code as shown in box 1. In this case however, that the person provide a suggestion, the html and the css is not really properly more Moor some css and html seems a little redundant. So this time, when I used the part "html" in the CSS code (i.e. just the bit that was no longer relevant), I had two different behaviors in each browser and neither of which was quite what I'm looking for. In IE8, initially the page seems well (background fills the page and the content is on top) but when I Zoom in or out the background also zooms in or out accordingly so is NOT fixed. In Firefox, the background image stays fixed, but because the image is initially not the height of the browser I guess the code it extends down (keeping the proportions - so the image enlarges essentially) to fill it. The fast way to get around it is probably add white space at the bottom of the image just to give it sufficient height is not extensible / resize automatically. But it would be nice to know at least how to work around this problem in the code. Overall, I would say that the result in Firefox is closest to the desired solution, but of course it is not arranged things with IE8.

    Apologies for the long description, but which should at least provide much info for anyone who might have a possible solution for me. Essentially what would be great is if someone could advise me how to take the code of case 1 and apply it to a piece of 'background' coding as the type that is contained in html {...} in Case 2 . Like I said, it is almost there, but I just can't operate atm after trying to combine different bits of code this way and that... Also, if anyone has another version of html-css that works well to achieve then please by all means of let me know! V thanks a lot in advance!

    It works in modern browsers of the CSS3 support.  But not pre - IE9.

  • How to get a RAW image not adjusted EPS

    How do you get a picture no adjusted Adobe Camera Raw in Photoshop Elements?  When I open a RAW file in ACR, the image is slightly different from the RAW (.nef) image as seen in other viewers the image.  I believe that the difference may be due to default settings in ACR.  What parameters corresponding to no adjustment at all?

    The default settings or in the context menu where it says

    Camera Raw default is closest to an unadjusted raw file

    This camera raw provides. The default settings can be changed,

    so, you might want to click on the shortcut menu and choose Reset Camera Raw default.

    Other spectators as decision-makers in the camera software, can bring up the different file

    because he can read the settings from the camera this camera raw reads no and some

    viewers aren't really color management.

    The idea of camera raw adobe is really to make the raw file resemble

    you want through the use of various adjustments in camera raw.

  • How to get a minimum Image display VI

    I am building a GUI for a multi camera ROVS (underwater Robot), and I want to include multiple streams of live image on the screen.

    I can get the workflow, but I seem to be stuck using one of the "Image display" VI two on the range of Vision.

    These have a range of additional features that I don't want and can't seem to turn off completely.

    for example:

    -There is a "high zone" with border around the image which is just take to the top of the real estate.  I can't reduce it to zero. (I tried the new and classic vi)

    -There is a range of tool that I don't want.  I have different windows "Preview" that just needs to be dumb views.  The tools are not only unnecessary, but a problem is that someone clicks on the image by accident.

    Then. Bottom line, I would like to just a stupid little Image display window VI which I feed with a wire IMAQ Image.ctl and who accepts no user intervention.

    Such a thing is available?

    Phil.

    You can turn off scroll bars, tool palette, as well as the Image information string. Then just resize the viewable area on boders:

  • How to get the best image quality when you insert PDF into Word?

    I am able to insert a PDF file as an object in Word, but the image quality is a bit fuzzy.  Is this what I can adjust in order to improve the clarity of the image in Word?

    You can try to extract the images with the help of extract all Images or select only the parameters of the screen recording you get when you save in a DOC, but I think that the general result is that the image recorded with the same resolution as shown in the PDF document. It may be that you simply adjust your screen in WORD. You can look at the picture in WORD and see if it is used at 100% or some other resolution. Bitmaps are not very forgiving if the resolution is changed to the document and not as something other than the small number of fractions of resolution appears change.

  • How to get the static attribute by using its name as a string

    I have an app with about 100 boxes of single drop-down list (this is a requirement of the Government, I'm not that bad a designer) and I would like to define the choices in a single file separated like this:

    package components {}

    Import mx.collections.ArrayCollection;

    public class {choice}

    [Bindable] public static var A0310A: collection ArrayCollection = new ArrayCollection ([] collection
    {value: '01', label: 'Admission'},
    {value: "02", label: "Quarterly"},
    .. .snip...
    ([{value: "99", label: "NOT the OBRA required"}]) ;

    public static void getChoices(name:String):ArrayCollection {}
    var temp: ArrayCollection = collection?
    Return temp;
    }

    }//----------------end of class--------------------------------
    }//======================== end of package==============================

    I want to use it like this

    < my: ComboBox id = "mdscombo" tag = "A0310A" / >

    Where the definition of my: ComboBox includes the code like this

    var zz:ArrayCollection = Choices.getChoices (name);

    but I can not find any function that will allow me to do.  I don't want really clutter up the code by creating a name-> object mapping table.

    I had also considered using the XML data type, but I have the same question, unless I had all the choices under a single root (possible), but this could be a nightmare when debugging in typo XML file.

    Any suggestions?

    To answer your question, you can access static variables with a chain in this way:

    Choice ["A0310A"]

    However, you probably want to re-evaluate your design because this isn't a very desirable approach.

    Since we are unable to connect by shell on a server ESXi, I would like to know if there is a way to copy all my iso OS locally on my new ESXi server.

    Is it possible to do?

    Johnny

    If the purpouse is to install the operating system you can set it up the computer virtual CD/DVD rom to be client and map the ISO of your client, then install the operating system.

    This isn't what you're looking for you can enable ssh for root by using the following URL and use winSCP to copy the ISO to any store data presented to the ESXi server.

    Hi, yesterday I asked for some ease of image horizontal scorlling with blackberry. It's work very well. Thank you for all.

    But I could not do my job. What I need, that I have to get the Image from a web site (not in the project of ths) and display it in the BB device. I can do this and I get byte array and show the image using BitmapField. But this installation of scrolling does not work with the bitmap field.

    You can use a browserfield to display web content in your application.  Take a look at the browserfielddemo provided with the BlackBerry JDE for example

    my suggestion was supposed to replace navigationclick on-screen.
    If you want to ignore it for the field that you do not have to use getLeafFieldWithFocus.

    I suggest that you think your code, don't write things and try to operate, fist think about something and then implement.
    our projects at the University were generally 80% design, 20% of coding - it was strange at first, but it produced a lot more code.

  • Last night suddenly when I right click view image in firefox, they appear centered and on a black background. He is generally meant to be a white background and the image that appears at the top left. How to get back to it?

    I have a problem with something in firefox, it is quite minor, but still bothers me. Last night suddenly when I right click view image in firefox, they appear centered and on a black background. He is generally meant to be a white background and the image that appears at the top left. I don't remember what I did to change this if it's my fault; If anyone knows how to get back to it, I would be grateful.

    This is the new behavior in Firefox 11.
