I am trying to display an image using the latest version of winui, without success.
Due to my lack of progress I assume I must be doing something terribly wrong, however, I can't determine what that might be.
Here is my most recent attempt.
MainWindow.xaml:
<Image Source="AppIcon.png" Width="200" Height="200" ImageFailed="ImageFailed_Event"/>
Image
Ok here is the solution that I have found with the help of the people in the comments:
Set the "Build Action" of the image file to "Content"
Set the "Copy to Output Directory" to "Copy if newer"
This is all that is necessary, no URI magic is needed.

Using LR 6.1.0-ce-ga1 and ICEfaces 3.2.0. Have this code in my xhtml:
<ace:panel>
<ace:fileEntry
required="true"
requiredMessage="You may not save if you have not selected a file."
fileEntryListener="#{profileBean.listener}"
maxFileCount="1"
maxFileCountMessage="Select one file, please."
useSessionSubdir="true"
immediate="true"
/>
</ace:panel>
First, the immediate doesn't work. listener in my bean never gets called. But that's maybe not as important as the following.
I have h:commandButton on the form. When I click it, I see what looks like the beginning of a progress bar drawn like it's going to display file upload progress. This is immediately covered by the following:
This box is often associated with ICEfaces push problems (I've been told by ICEfaces). I added icepush.jar to WEB-INF/lib, but it didn't help. What I'd prefer is not to have the alleged progress bar try to render at all.
So, would appreciate anyone's help in making this file upload work.
P.S., I've tried Tomahawk and plain Apache JSF 2.0, also. I'd like to get the ICEfaces version working, but I'm kind of open to any working solution, given my (Servlet 2.5-based) environment.
Thanks.
I would recommend that you look at the source code for the icefaces3-portlet demo, as it shows how to upload a file with ace:fileEntry in a portlet environment.
I have a jar I include with my application with some fonts. If I paste around
<font fontName="NimbusSansGlobal Light" size="12" pdfFontName="NimbusSansGlobal Light" pdfEncoding="Identity-H" isPdfEmbedded="true"/>
into all my text elements, PDF output works fine. If I switch them all to use a style which defines the font as such:
<style name="SansFontStyle" isDefault="true" pdfFontName="NimbusSansGlobal Light" pdfEncoding="Identity-H" isPdfEmbedded="true"/>, then the font can't be found by the JRLoader when I try to generate reports. Interesting enough, if I use JRLoader within my application directly, the font is found fine.
Why would styles break PDF export?
Using Font Extensions should solve this problem.
Once you use font extensions, then you can set the font in the text element or in the style. You will not specify pdfFontName, pdfEncoding, or isPdfEmbedded in the report. That gets specified in the font extension.
Note: In a strict interpretation, this doesn't actually answer the question. I have no idea why styles work differently from directly setting the fonts. It seems like a bug, but maybe it's unexpected yet intentional for some reason we aren't thinking of. Therefore, I started to enter this as a comment rather than an answer. But it got too long.
Regardless, this should allow you to use styles as you want to. So I expect that it will solve the heart of the problem.
Font extensions are documented in the JasperReports (and iReport) samples and documentation, so it should be pretty easy to use them once you know that you ought to.
I'm making a Windows Phone 7 application and I'm a bit confused with dark/light themes.
With a panorama, you very often set a background image. The issue is it's very hard to make a picture which is right for both dark and light themes. How are we supposed to proceed?
Is there a way to force a dark/light theme for a panorama? This will avoid making theme-specific panorama background pictures. Then how do I do? I found xaml files in C:\Program Files (x86)\Microsoft SDKs\Windows Phone\v7.0\Design. If this is a right way to proceed, how can I import them for my panorama?
Or if there's no way (or if it's wrong) to force a dark/light theme: how to write conditional XAML to set correct resources? Now I have the following XAML (default.xaml) which is fine with the dark theme:
<ImageBrush x:Key="PageBackground" ImageSource="Resources/PageBackground.png" Stretch="None" />
<ImageBrush x:Key="PanoramaBackground" ImageSource="Resources/PanoramaBackground.png" Stretch="None" />
But when I use a light theme, black controls and black texts are hard to read with my dark background pictures. So I made different pictures that I can use this way:
<ImageBrush x:Key="PageBackground" ImageSource="Resources/PageBackgroundLight.png" Stretch="None" />
<ImageBrush x:Key="PanoramaBackground" ImageSource="Resources/PanoramaBackgroundLight.png" Stretch="None" />
Now my issue is to make XAML conditional to declare the right thing depending on the current theme.
I found no relevant way on the Internet. I would prefer not to use code or code-behind for that because I believe XAML is able to do this (I just don't know how).
EDIT: Code snippet to load a xaml file as ResourceDictionary
string xaml = null;
StreamResourceInfo xamlInfo = Application.GetResourceStream(new Uri("light.xaml", UriKind.Relative));
using (StreamReader sr = new StreamReader(xamlInfo.Stream))
xaml = sr.ReadToEnd();
dic = (ResourceDictionary)XamlReader.Load(xaml);
this.Resources.MergedDictionaries.Add(dic);
To force a dark or white theme you can indeed use the styles defined in the folder you pointed out. Copy and Paste the rules you need to your App.xaml (just PhoneForegroundColor, PhoneBackgroundColor and the related Brushes would be a good start).
It's probably better though to stay "theme-aware" and load a different image for light and dark themes. Here is an article explaining how to do this: http://blog.jayway.com/2010/12/16/theme-aware-panorama-background-in-windows-phone-7/
There is another possibility I've found: You can use the Coding4Fun Toolkit Converter according to these instructions. However, I'm unable to use correctly use them.
Another possibiliy is to use an OpacityMask. But this only works for black/white images :/
Yousef's solution looks interesting. but it takes too much time to load. The image will be changed round about 1s after the app started. I've tested this on a Nokia 820. I've moved the call for setting the DataContext in a Loaded Event, which was called much later. Now the call takes place in the constructor, so the image will be already set when the application displays it. However, it still adds more loading time :( Any suggestions on how to improve this?
I download IKImageBrowserView sample named "IKImageKit Demo" from Apple official website.
But I find a problem.
For example:
When I import images from folder named "A", then I delete an image.
Then I import other image (name as same as the deleted image), the thumbnail in
IKImageBrowser will not change.
How could I resolve this problem?? Thanks!

I came across a reference that said the internal cache IKImageBrowserView uses looks up thumbnails by ImageUID. So if you change the ImageUID that your data source returns to be something other than just file name (maybe file name + file size), then it will be treated as a different image.
You should take a look at the IKImageBrowserItem Protocol's imageVersion method. If you need to let IKImageBrowserView know that a item has changed its image you can increment the imageVersion. This will force the view to update the cached image.
Update: Wow, old post. Looks like the documentation was updated a while after I had posted; as the other answers suggest, looks like you need to increment the image's imageVersion to update an image from cache.
After mulling over the problem for close to three hours (once I started, it was really bugging me, too!), I came to the sad conclusion that it's a bug in how IKImageKit handles images. IKImageBrowserView has a cache of images and thumbnails, and from whatever experimental data I have, I'm guessing that it just caches its images based on location on disk, and not on image data (so it can load the data lazily, I guess), so even if the actual image data can change, reloading the same file location will not update the image itself.
Of course, I could be completely wrong - which wouldn't surprise me, since there's literally no documentation on the issue, so I have nothing but results from Instruments and the app itself to guide me - but my advice to you is to ignore the issue for now, since there's nothing you can do about it, and possibly file the bug with Apple.
Of course, if anyone can introduce other evidence about this, please do! I'd love to know more about it.
Good luck!
you should want to imageVersion update or name the image of the path.
if you delete image with name "1.png" after you put image if it's name "1.png" the image browser view show the previous image so you should take care of image naming. or imageVersion method.
I have a reasonably large Silveright 3.0 project on the go, and I'm having issues accessing a couple of custom font resources from within one of the assemblies.
I've got a working test solution where I have added a custom font as a resource, and can access it fine from XAML using:
<TextBlock Text="Test" FontFamily="FontName.ttf#Font Name" />
The test solution consists of the TestProject.Application and the TestProject.Application.Web projects, with all the fun and games obviously in the TestProject.Application project
However, when I try this in my main solution, the fonts refuse to show in the correct type face (instead showing in the default font). There's no difference in the way the font has been added to project between the test solution and the main solution, and the XAML is identical.
However, there is a solution layout difference. In the main solution, as well as having a MainApp.Application and MainApp.Application.Web project, I also have a MainApp.Application.ViewModel project and a MainApp.Application.Views project, and the problem piece of XAML is the in the MainApp.Application.Views project (not the .Application project like the test solution).
I've tried putting the font into either the .Application or .Application.Views project, tried changing the Build Action to Content, Embedded Resource etc, all to no avail.
So, is there an issue accessing font resources from a child assembly that I don't know about, or has anyone successfully done this?
My long term need will be to have the valid custom fonts being stored as resources in a separate .Application.FontLibrary assembly that will be on-demand downloaded and cached, and the XAML controls in the .Application.Views project will need to reference this FontLibrary assembly to get the valid fonts. I've also tried xcreating this separate font library assembly, and I can't seem to get the fonts from the second assembly.
As some additional information, I've also tried the following font referencing approaches:
<TextBlock Text="Test" FontFamily="/FontName.ttf#Font Name" />
<TextBlock Text="Test" FontFamily="pack:application,,,/FontName.ttf#Font Name" />
<TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;/FontName.ttf#Font Name" />
<TextBlock Text="Test" FontFamily="pack:application,,,/MainApp.Application.Views;component/FontName.ttf#Font Name" />
And a few similar variants with different assembly references/sub directories/random semi colons.
And so far nothing works... anyone struck this (and preferably solved it)?
This code works for me:
... FontFamily="/(DLL);Component/(DIR-optional)/(Font_file)#(Font_name)"/> ...
