I tried to add image in Launch screen (Logo) in storyboard but doesn't display
I Followed Xamarin documentation but no way .. when i drag and drop image and set image to image set which i added in assets nothing changed
Launch screen works fine if i change background color or something like that
Note : In story board when i try to select image view image .. it open
explorer didn't make me choose from image set
how can i solve this issue ?
If you want to use Asset catalogs in the LaunchScreen.storyboard, it is not necessary to name the Asset file as LaunchImages. Click the add button at the left top of this window, you will get an Asset file named Images. You can rename it then add three sizes of images(1x, 2x, 3x), after doing that this image can be used adapting all apple phone devices.
Then click save all button at the top window or use Ctrl + Shift + s to save this behavior. At last drag and drop down an Image view control on the LaunchScreen.storyboard, you will find this image called the Asset file's name instead of the images' original name in the image view's property window's image list.
when i follow this it works fine

I am implementing a splash screen for my app. I just came to know about storyboard constraints to support multiple devices. Basically, I feel it very difficult to understand it as a beginner in this, also I see there is no apt documentation in xamarin also. I want to know the steps to set an imageview width to its super view (View controller).
I see what I should do from here, Visual studio Xamarin iOS launchscreen storyboard layout. But, how do I add those constraints, totally no idea..?! Particularly imageview width and height to superview, trailing and leading
Now, I can only know how to set the constraints in designer by dragging, I'v only learnt to center the image to super view in X and Y (Horizontally and vertically). There is no button to add constraints. How to add leading and trailing constraints? I'm using Visual Studio 2017 for Windows
I got it working.
Step 1: Open storyboard file with lowest screen resolution device set (iPhone 4s) and drag & drop an imageview to fill the view controller.
Step 2: Set the uiimageview source from resources/image assets.
Step 3: Click on the image -> Properties Tab -> Layouts section. You will see like this
Step 4 : Properties -> Layout -> Under View group, there is title called Arrange, there is a autosizing box and example box.
Step 5 : You should click all the I-bars and lines in the center to make it red like below to fill the width (you can see that reflecting in the example box as you click)
Now, SAVE and then switch to other devices, you should have that UIImageview filling the device's height and width.
This will be very useful for important UI auto designs like splash screen.
For a touchscreen I need to increase the height of my buttons in a ABAP WebDynpro Application.
Because there's no attribute for the height I read that it should be possible to add an image to the MIME Repository and then add this image to the button.
I also read that it might be possible to create a own theme with a .css file.
The last one sounds a little bit better to me. Does anyone know how I can create such a theme and apply it to my application?
Thanks for your help!
The simpliest way of resizing height is using MIME image, which I want to describe here:
Create your image with exactly those height that you need. The image could be opaque, transparent or whatever. Image format doesn't matter, as most common formats (jpg, gif, png) are supported.
Import it to your Webdyn Pro component like this: right click on component in repository tree, then -> Create -> MIME object -> Import
After image was successfully imported, just select it using imageSource property of button element, where you can find it on Component images tab.
Voilá! The button adopted the dimensions of the image.
I have a ribbon-base app and on it's toggle buttons I'm placing PNG icons - 32x32, 32 bits. But when I'm launching the app the image on the ribbon button looks corrupted. Just to checkk I've create a simple button control with the same image on it - and it looks ok. see the screenshot here - http://i.imgur.com/0zct9cf.jpg
I've tried to add RenderOptions.BitmapScalingMode="HighQuality" and RenderOptions.EdgeMode="Aliased" to my app window tag - no luck.
Can someone explain whyRibbonToggleButton corrupts the images on it?
Thank you!
Try saving the image with a program that supports setting the DPI in the metadata, for example IrfanView. I had a similar problem and changing the images DPI to match the screen fixed it for me.
Open the image in IrfanVIew and press shift+i to open the image information dialog
Change the DPI to match your screen
Save the image
I have not tested this on a screen that is set to a different DPI, so I have no idea if this will look even more horribly wrong then.
I have a transparent windows (skinnable).
Inside, I'd like to preview some pdf file.
BUT, in the only a black screen appear, can you help me?
Thanks
The only solution I found is to have a window with no tranparence option
Thanks
Please provide more details. If you embed the respective component inside a standard window, does it show the PDF as expected?
Additionally, these links might be of interest:

Are you using an HTML component? If so, it's impossible to show PDF if your window is transparent. Here's the note from the Adobe documentation. I highlighted the interesting part. (source : http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/html/HTMLLoader.html)
Note: When displayed in a transparent window, SWF content embedded in
an HTML page must be embedded using either the transparent or opaque
wmode. The default value for wmode is window, so if you do not specify
a value, SWF content may not be displayed. On Windows and Linux, SWF
content always appears on top of other content when wmode is set to
window or opaque. PDF content cannot be displayed in a transparent
window no matter which wmode setting is used.
You could show the PDF inside another window perhaps ? If you can't maybe you can find a way to open an invisible window, load the PDF there, draw it into a BitmapData oject then display the snapshot instead. Off course, this means no user interaction with the PDF whatsoever.
I have placed 3 images into UIImageViews using xcode4 interface builder: background, and two pictures. Background image fills the whole visible area and it looks the same in interface builder, in simulator and on device. In addition, I'm placing another image at the very bottom (stick to) of visible area, and another one on top of it. Both looks as I want in interface builder. The problem is both bottom image and on top of bottom image moves approximately by 50 pixels up when running in simulator or iphone4 device. Interesting part is that background image fill whole visible area. I should note that I'm using UIInterfaceOrientationLandscapeRight orientation so the status bar in my orientation should appear on top but I have disabled it in plist, so I guess it's not related to this problem. Both of my problematic UIImageView's have mode "Bottom". Also, all of three images have #2x image twin. But why can see everything OK in interface builder and then some shift on simulator and device? Also, strange why background is not moved. Does anybody had the same problem?
Try hiding all elements in your nib. (status bar, tool bar, etc)
Make sure you have your springs adjust for your desired effect.
Hope this helps!
