I had heavily modified the canvas theme via child theme.
There is ugly border around the images in Internet explorer. Take look on the below screenshot and help me to resolve the same.

Please help me to troubleshoot this CSS issue.
This is either a bug due to the VM being in 16bit colour or IE6's jpeg decompression techniques. Either way I don't think it's your website and I would advise you to just ignore the problem, stop worrying about IE6.

I've been using Sketch for years now and of course I love it. Recently tho I've come across a strange bug. When I have a font layer selected I can't change the font face. It doesn't matter what font I have selected. The fonts are installed. I have to right-click and change the font properties from the font menu. The font pulldown flashes when I click on it, but I can't see or select any other fonts. Any ideas why this would suddenly happen? I use Skyfonts, but I doubt that's an issue. Thanks!
I'm having the same issue right now.
The strange thing is, that it's only happening on "older" files.
For example, if I create a new Sketch file and type something, I can change the font face.
I'm sure, Bohemian already knows about this. But for now, a work-around is to create a new file, type something, change the font and copy the font into the other file.
I hope this helps!
This is a bug in the newer version of Sketch. Downgrading resolves the issue...
Here you can downgrade to any version here: https://www.sketchapp.com/updates/
The issue has been fixed in the new sketch(ver:51.1).
We have a few icons in our WPF application. We want to do an animation, pretty much like a small beacon of light going around the edges of the animation, just endlessly going around it, and following the silhouette of the icons. We found a way to do it by manually creating a path around the icons and have the beacon follow that path (which matches the silhouette), but it's too much manual work because we have a lot of different shaped icons. We're wondering if there's a way for WPF to do this automatically, so we just have to program it once, and then using on the rest of the icons.
Any suggestion very welcome.
Thanks.
Edit
Something like this.
Gee. Isn't that overkill to use wpf animation capabilities for that? Can't you just create a bunch of small animations in Photoshop or using something else and just put them in?
Like animated .GIFs. the only problem would be that: if I'm remembering it right, WPF have problems with animating .GIFs as embedded resources. So you have to load them from the disk. Or you can have them as embedded resources, but you have to extract them temporarily to the disk and then load them into your app's window.
If you are using .NET 3.5 SP1 or greater and you are requiring a code solution instead of the animated GIFs, my suggestion would be a Pixel Shader. You would need to write your own Pixel Shader that does the following:
Detect the edges. http://www.codeproject.com/KB/openGL/EdgeDetection.aspx
Takes an input parameter that can be animated with a storyboard that indicates the position of the beacon. http://www.codeproject.com/KB/dialog/WpfParentWindowShader.aspx
Highlights the edge that is indicated by the beacon position parameter and returns the original color for all other points in the image.
If you haven't worked with Pixel Shaders I would recommend downloading the Shazzam Tool, http://shazzam-tool.com/. It includes an interactive development environment to create and test your shader on simple images and also includes a decent number of Pixel Shaders with source code to help you learn about them.
I'am testing a WPF application, and I have noticed a strange issue.
I am using duel monitors one is using the 32bit High colour, the other is using 16bit Medium colour. This is so that I can match the resolutions nicely.
If I open the application on my high colour screen I have no problems, but if I open it on my medium colour screen I get a terrible graphics lag, as soon as I move the mouse over the application. It makes it impossible to use the app on this screen.
Is this likely to be a problem with WPF or the Application? and is there any way to fix it?
Thanks in advance.
This an issue with the graphics pipeline; it has been described by Raymond Chen.
In short, don't do that.
Avoid monitors with differing color depths at all costs.
Just had the same problem... A colleague found out, that the problem is the Windows-Transparency. If you deactivate that on the 16bit screen, it works.
I have a lot of images taken from a 360 camera which I would like to be able to display in Silverlight 3. They are NOT regular panorama images. The camera which took the image actually creates a distorted jpeg that becomes undistorted once wrapped around a sphere as a texture. I have desktop software that will allow viewing of the image (not just side-to-side, but straight up, down, etc.) and I need to try to get the same functionality in Silverlight. It is very similar to Google StreetView.
What I think I need is to create a sphere, wrap the jpeg on the sphere as a texture, then put the "camera" inside the sphere. I doubt this is possible in Silverlight, but perhaps there is a way to simulate this?
So far, Google searches aren't bringing anything up. Can anyone point me in the right direction to figure out how to do this? Are there any existing projects that do this?
An example of a typical image is here.
These might help you out (probably not). They are 3d engines for silverlight, but they will probably wrap the image outside of the sphere instead of inside, which is probably what you need.

Another, possibly more promising option, would be to use javascript. So far you've probably researched how to do this in Silverlight, but you might do some similar searching for using javascript for this. There may be an option out there already, and since Silverlight can interopt with Javascript, you might be in luck.
Your gonna have to map the texture to a sphere then, like you said. But afaik silverlight 3 doesn't support hardware accelerated 3d.
So your options are:
Try and find a silverlight software 3d library (Like this)
Write your own software rasterizer (multi page guide)
Hope this helps
You might want to try cropping a window from the image and display it. if the user want to go right, move the window right and crop. if the user wants to go left, move the window left and crop. to zoom out, expand the window, to zoom in make the window smaller. if you move the frame far right then stitch the image data from the left side.
You might need to modify the image to eliminate the distortion, this shouldn't be too hard and depends on the camera lens focal length.
Don't try mapping the image to a sphere, it is much harder.
At https://hdviewsl.codeplex.com it says that HD View SL (Silverlight version) supports
"orthographic (2D), with wrapping for 360-degree panoramas"
Also you could try to port PtViewer source code to Silverlight from Java if no one else has
UPDATE:
VRLight might be the solution in your case:

I have a Silverlight control that tries to have the same background as the underlaying div, but I'm facing color difference problems in IE7/8:
That doesn't seems to be a problem for Firefox.
Does anyone has a tip how to solve this problem? I try to avoid using the windowless mode in Silverlight and alpha transparency as 1st) it's slower and 2nd) shows a bounding select box when you click in the control in Firefox.
Fortunately I managed to solve the problem. Seems that it's a gamma correction problem. The PNG file allows you to set gamma correction information and Silverlight and IE seems to handle it differently.
This page explains the problem and saved the day. This tool as also necessary to remove the gamma information from the PNG.
Hopefully this information will be useful for someone.
