ImageView files

Recent Utilitybill only gave imageview.spx as the ability to view my Bill. How can I handle this. ?

In fact, when I search imageview.aspx it seems to be used for images (the meaning of the name), then you can try to rename it with an extension .jpg on the assumption that this is probably a JPEG image.

Working with GIF Image

Hello guys,.

I want to use a GIF image in a Qml (ImageView) file.

I've used this, but it did not work. (No animation)

ImageView {}
horizontalAlignment: HorizontalAlignment.Fill
verticalAlignment: VerticalAlignment.Fill
ID: imageView
imageSource: "3.gif".
attachedObjects:]
ImageAnimator {}
ID: imageAnimator

Load image into ImageView using file:///

Hello

According to this article http://supportforums.blackberry.com/t5/Cascades-Development-Knowledge/The-Different-Methods-of-Loadi... we should be able to load images QML using file:/// and absolute path.

For the life of me I can't load an image not only of shared/accounts/1000/shared/subfolders, but even of the application data folder.

Can someone share * work * example of loading images in ImageView using file:///

Thank you.

ImageView expected to auto-sense orientation

A few comments to the people of the API:

Shouldn't the ImageView read the EXIF of a JPEG image and automatic image rotation? And so by default, shouldn't there not a property such as 'autoOrient' or 'function' that this happens?

Seen developers manually read the EXIF data, manually turn the images, etc., seems to be a waste of developer time.

Follow-up question: if I do it manually and you end up with a QImage, how to recognize an ImageView to use a QImage? Is this possible?

And one last question followed: what type is the property of 'image' of the ImageView? He says it's a QVariant, but is not very useful. Can we set this property, or is read-only? Overall, I think that the "image" property documentation could use some improvements.

Thank you

Integration of ImageView and Qimage

A large part of this issue has been discussed here:

http://supportforums.BlackBerry.com/T5/Cascades-development/imageView-Cascades-noob-question/TD-p/17...

Basically, the suggested correct way of converting a QImage ImageView is this one:
```
PixelBufferData pbd (PixelBufferData::RGBA_PRE,yourQImage.width(),yourQImage.height(),yourQImage.width(),yourQImage.bits());

yourImageView->setImage(pbd);
```
Then there was someone by specifying the format must be probably BGR instead of RGB, which could be done with OpenGL or like this:
```
image.rgbSwapped();
```
Here is my code I have a problem with:
```
PixelBufferData pbd(PixelBufferData::RGBA_PRE, orgPattern.width(), orgPattern.height(),  orgPattern.width(),  orgPattern.rgbSwapped().bits());
m_patternFrame->setImage(pbd);
```
orgPattern is a QImage loaded from a file path that is sure to exist. m_patternFrame is a pointer to the ImageView.

I know that m_patternFrame is a pointer valid because if I call its method setImageSource by the way I created the QImage, it displays this image. But when I run this code, it is printed in the console:

Context: Cannot find the node target with id %d 906.

Sometimes the number is different. When I tried again, it was 563. The application is not cursh or gel, but nothing happens with the framework, it is still empty.

Can anyone provide any help with this problem?

Thanks for starting a new thread and referring to another thread. Allows us to provide you with a timely response.

Before dive us into this too far, what is the width and height? (We are within the limits, I guess?)

And can you try to make the setImage in 2 steps: first to create the Image of the PDB rather than implicitly and test! image.isNull)

Filepicker several files

Hi all

Try using filepicker to take several pictures and place them in different imageViews at the same time.

That's what I have so far for one frame at a time:

{FilePicker}
ID: picker1
Title: qsTr ("select an image")
string selectedFile property
mode: FilePickerMode.Picker
type: FileType.Picture
directories: [' / accounts/1000/shared/camera "]
viewMode: FilePickerViewMode.GridView
sortBy: FilePickerSortFlag.Date
sortOrder: FilePickerSortOrder.Descending
imageCropEnabled: true
onFileSelected: {}
selectedFile = selectedFiles [0]
imgView1.imageSource = "file://" + selectedFile
imgView1.visible = true
imgView1.scaleX = 1
imgView1.scaleY = 1
imgView1.rotationZ = 0

}
}

It works perfectly if I want to select a photo and place it in imgView1... but I imgView 1, 2, 3, 4, 5, 6, 7.

I would use the file selector choose 7 photos and put them in each imgView. I use FilePickerMultiple and it works great but can't seem to the get into each imgView separately.

Tried:

imgView1.imageSource, imgView2.imageSource, imgView3.imageSource is "file://" + selectedFile

Does not return an error but puts only the last selected photo imgView3 and not imgView1 or 2.

Any help would be amazing.

THX.

Thank you very much!!!

Worked surprisingly well... you're a genius... you made my day.

This is what the code looks like on your help:

{FilePicker}
ID: picker7
Title: qsTr ("select an image")
string selectedFile property
mode: FilePickerMode.PickerMultiple
type: FileType.Picture
directories: [' / accounts/1000/shared/camera "]
viewMode: FilePickerViewMode.GridView
sortBy: FilePickerSortFlag.Date
sortOrder: FilePickerSortOrder.Descending
imageCropEnabled: true
onFileSelected: {}
for (var i = 0; i)< selectedfiles.length;="">
var selectedFile = selectedFiles [i];
imgView.imageSource = "file://" + selectedFiles [0]
imgView1.imageSource = "file://" + selectedFiles [1]
imgView2.imageSource = "file://" + selectedFiles [2]
imgView3.imageSource = "file://" + selectedFiles [3]
imgView4.imageSource = "file://" + selectedFiles [4]
imgView5.imageSource = "file://" + selectedFiles [5]
imgView6.imageSource = "file://" + selectedFiles [6]
imgView7.imageSource = "file://" + selectedFiles [7]

}
}
}

He brings in 7 different photos in separate different imgViews... Impressive... just great!

Thank you.

See the thumbnail of the file

Hi guys,.

When I explore BB10 mmlibrary I get thumbnail of the files in the device. It's a chain like that
```
/fs/sfs/mmsynclite/IMG/88cdfeb9c31e6a59_256X256/3.jpg
```
I wonder just where are the location of the files and how do I show in an ImageView in my project.

Thanks in advance

You can try to look in file:///fs/sfs/mmsynclite/IMG/

It should work because debugging NowPlayingController cough this URL for the media, do not see why your tile would not show if she is looking in the same folder for the Source ImageView

file:///FS/SFS/mmsynclite/IMG/2c69ba0b81908e1a_256X256/2653.jpg

File for images of the Asset Picker

Hello

Here's the current code

        FilePicker {
            id:filePicker
            type : FileType.Picture
            title : "Select Wallpaper"
            directories : ["app/native/assets/images/"]
            onFileSelected : {
                console.log("FileSelected signal received : " + selectedFiles);

                //make sure to prepend "file://" when using as a source for an ImageView or MediaPlayer

            }
            defaultType: FileType.Picture
            sourceRestriction: FilePickerSourceRestriction.LocalOnly
            viewMode: FilePickerViewMode.GridView
        }

The problem is with the directories.

I get the error "Cannot find source.

Anyone got any ideas how I could take the images stored under assets/images /?

FilePicker works like a card, which means that it is indeed another application. I don't think that he can access your data area of the app sandbox.

Loading image file system

Hello

I want to load the special position of my file system image but image is not loaded and I am not able to see the image on siumulator.

Here is my code for the same thing.

Image image = Image (QUrl("D:\Megha\linux.png"));)

ImageView * ImageView = pMyImageView:: create();
pMyImageView-> setImage (image);

Page * new = Page() page;
Page-> setContent (pMyImageView);

Application::setScene (page);

But no image is copied

You hardcoded the path to D: likely this file is not in this location on the Simulator or device.

See the documentation in https://developer.blackberry.com/cascades/reference/bb__cascades__image.html for this relative setting or using your assets.

Image inherits from resource, so isNull(). IsValid() and isEmpty() QUrl a.

You need to add defensive code.

Animated images in place when loading new QML file

I noticed that when I insert new QML files, the images Animate into place.

For example, if the screen contains an image at the position X, Y, and width W and height H, then the image becomes visible at the point of coordinates 0,0-0 width and height 0 and anime then in place by flying over to the X, Y coordinates and more in addition to being finally width W and height H.

If I then click on the 'Back' button and enter this QML screen a second time, it does not animate.

This implicit animation is intended? While the implicit animations are pretty amazing and a great tool to have, it seems intuitive to the use of screens animations implicit when they are first loaded. It creates a rather unpleasant company and Visual distraction when loading screen.

I thought that I could disable it by adding the following to the ImageView controls:
```
                attachedObjects: [
                    ImplicitAnimationController {
                        enabled: false
                    }
                ]
```
... but they are always animate.

Thank you

Daniel

Did you notice the sample code above? (yes)

This seems to be fixed with the latest SDK.

Push the files in the Simulator

Hello

I would choose a file specifically images and view it in the imageview.

But now I am unable to crack how to send pictures on the Simulator.

My camera does not respond within the Simulator as well.

Unable to restore the ImageView ListComponent - image of the data folder

I downloaded an image in the folder data and want to show it in the listView.

In Listcomponent, I use an ImageView

"If I put its imagesource:".. /.. /.. "/ data/files/images/123.png".

The image appears correctly.

But if I try to put the same path of C++ code in the GroupDataModel, the image doesn't make.

                        imageSource: ListItemData.imagepath
                    }
                }
            ]
        }
    }
}

Currently, I put a static image and a rest black. It will have the value during the click on list black image (dynamically).

Data model with ImageView not displaying the image on OS10.1

in the qml, I have a ListView with a DataModel. The DataModel contains a label and ImageView.

I put the ImageView and etiquette like this

Entry QVariantMap;

QFile file (picture_file); file stored on the device
QFileInfo fileInfo (file);
QString qmlPath (fileInfo.absoluteFilePath ());

the path of the file would like something like that

/Accounts/1000/APPDATA/com.example.TestApp.testDev_e_TestApp4a417186/shared/photos/TestApp/MyPicture.PNG

entry ['image'] = QUrl (qmlPath);
entry ["name"] = "Text";

It works on 10.0.9 but when I recompile the target app to 10.1 or the image is not displayed. The label is.

Also, if I set the imagesource to the current folder the image appears fine.

entry ['image'] = "asset:///images/template.png";

What is the correct way to set the imageSource for ImageView?

I think your problem will be solved by file:// adding to the path of your file.

ImageView Black question screen on DA - anomaly or something else?

Hello friends,

I'm developing an application of connected local transit. Part of it includes essentially maps for each bus line. I use nested within a ScrollPane ImageView. Many of the cards are superior to a dimension 768 and 1280.

Question

ScrollPane ImageView displays BLACK on some images, but not others. I can't understand why and how to fix it.

My Application configuration

Standard C + c++ / Cascades project
Directory structure
[Standard empty project template]

+ assets
-main.qml

import bb.cascades 1.0

//-- create one page with a label and text

Page {
    content: Container {
        layout: DockLayout {
        }
        background: Color.create("#FFFFFF")
        preferredWidth: 768
        preferredHeight: 1280
        ScrollView {
            id: mapScroll
            scrollViewProperties {
                scrollMode: ScrollMode.Both
            }
            // This ImageView Appears Black on the DA - qml preview in IDE ok
            /*ImageView {
                id: m45ustock
                preferredWidth: 2913
                preferredHeight: 2283
                imageSource: "asset:///images/m45ustock.png"
                onTouch: {
                    mapScroll.scrollViewProperties.scrollMode = ScrollMode.Both
                }
            }
            */
            // THIS ImageView DISPLAYS CORRECTLY
             ImageView {
                id: m10town
                preferredWidth: 1287
                preferredHeight: 1631
                imageSource: "asset:///images/m10townsend.png"
                onTouch: {
                    mapScroll.scrollViewProperties.scrollMode = ScrollMode.Both
                }
            }
        }
    }
}

Create a folder "images" add attached images.

- images
-m10townsend.png
-m45ustock.png

Notes

I commented the ImageView displaying BLACK. Toggle comments to test.

Why is this happening?

Ideas? Is this a bug? Are there restrictions on the ImageView in terms of file size, making it the dimensions, etc.?

Thank you!

Have you gotten nowhere on that?

If you need to do a program, one way is to use http://supportforums.blackberry.com/t5/Cascades-Development-Knowledge/Using-QImage-and-QPainter-to-P...

Was it the root cause of your problem?

Help me solve my problem with onTouch imageView acted before I have a chance to scroll the Please

Hi, please help.
I have a little imageviews in a scrollview. Notecard will sail me to another page, however, at the time wherever I touch the image, it takes me to the appropriate page with no chance to scroll down. How to scroll and then press the image to navigate. It seems that notecard is competing with scrollview and ontouch victories.

How I've implemented to scroll my arranged vertically imigeviews and then when I find the question I want to, I touch it and it goes to the next page which is a separate qml file.

scrolling workes fine when I commented the notecard section and ontouch fine work as well.

I like:

ImageView {}
horizontalAlignment: P
imageSource: "asset:///images/Sunshine.jpeg."
preferredWidth: 700,0
preferredHeight:200.0
minWidth: 30.0
minHeight: 30.0
Notecard: {}
page var getThirdPage() =;
Console.Debug ("pushing retail" + page)
navigationPane.push (page);
}
Property Page thirdPage
function getThirdPage() {}
If (! thirdPage) {}
thirdPage = thirdPageDefinition.createObject ();
}
Return thirdPage;
}
attachedObjects:]
{ComponentDefinition}
ID: thirdPageDefinition
Source: "thirdfilepage.qml".
}
]
}

I have several of these points of view image, wraped in a single scrollview.

I tried to find it through Google as well as the documentation of cascades with no luck. I'd appreciate any help, please

Thank you
Roland

I'm glad that it worked without any problems!
