Scaling of PathIcon in AppBarButton

Question

Hi,

I am using a PathIcon with the new AppBarButton (which is a great addition, BTW).  I have located a nice icon on http://modernuiicons.com and uses its path data in my AppBarButton. The problem however is that the path seems to be bigger than the button, so only a section of the icon is visible, and the rest falls outside the limits of the button.

Is there a way to the the PathIcon to automatically scale the path data to fit inside the constraints of the button?

Example XAML

            <AppBarButton Label="Path Icon">
                <AppBarButton.Icon>
                    <PathIcon Data="F1 M 30,27C 30,24.3766 32.3767,22 35,22L 41,22C 43.6234,22 46,24.3766 46,27L 50.9999,27.0001C 53.7613,27.0001 55.9999,29.2387 55.9999,32.0001L 55.9999,46.0001C 55.9999,48.7615 53.7613,51.0001 50.9999,51.0001L 25,51.0001C 22.2385,51.0001 20,48.7615 20,46.0001L 20,32.0001C 20,29.2387 22.2385,27.0001 25,27.0001L 30,27 Z M 25.5,30C 24.6716,30 24,30.8954 24,32C 24,33.1046 24.6716,34 25.5,34C 26.3284,34 27,33.1046 27,32C 27,30.8954 26.3284,30 25.5,30 Z M 38,32C 34.134,32 31,35.134 31,39C 31,42.866 34.134,46 38,46C 41.866,46 45,42.866 45,39C 45,35.134 41.866,32 38,32 Z M 38,34.5C 40.4853,34.5 42.5,36.5147 42.5,39C 42.5,41.4853 40.4853,43.5 38,43.5C 35.5147,43.5 33.5,41.4853 33.5,39C 33.5,36.5147 35.5147,34.5 38,34.5 Z"/>

            </AppBarButton>

Thanks

Hi Jerrie,

if you look at the PathIcon in the Properties-Window, you'll see that its Width and Height both defaults to 40. I was not able to figure out how to scale it, so I think it's not possible. When using ScaleTransform with the PathIcon it's cut off like in your case, even if I set Width and Height to larger than 40 before.

But of course I wouldn't answer here without a solution. :-)

I think the Data needs to be in the 40x40 range. So you need to transform your data. Look here:

  <AppBarButton Label="Path Icon">
        <AppBarButton.Icon>
          <PathIcon Data="M16,14.2000007629395L16.2474098205566,13.0672025680542 16.9097576141357,12.1097354888916 17.8672275543213,11.4474010467529 19,11.2000007629395 22.6000003814697,11.2000007629395 23.7327995300293,11.4474010467529 24.6902656555176,12.1097354888916 25.3526000976563,13.0672025680542 25.6000003814697,14.2000007629395 28.5999412536621,14.2000598907471 29.767671585083,14.4358167648315 30.7212562561035,15.0787448883057 31.364185333252,16.0323314666748 31.5999412536621,17.2000598907471 31.5999412536621,25.600061416626 31.364185333252,26.7677917480469 30.7212562561035,27.7213764190674 29.767671585083,28.3643054962158 28.5999412536621,28.600061416626 13.0000009536743,28.600061416626 11.8322458267212,28.3643054962158 10.8786630630493,27.7213764190674 10.2357482910156,26.7677917480469 10,25.600061416626 10,17.2000598907471 10.2357482910156,16.0323314666748 10.8786630630493,15.0787448883057 11.8322458267212,14.4358167648315 13.0000009536743,14.2000598907471 16,14.2000007629395z M13.3000001907349,16L12.663610458374,16.3514652252197 12.4000005722046,17.2000007629395 12.663610458374,18.0485363006592 13.3000001907349,18.4000015258789 13.9363899230957,18.0485363006592 14.2000007629395,17.2000007629395 13.9363899230957,16.3514652252197 13.3000001907349,16z M20.8000011444092,17.2000007629395L19.165168762207,17.5300579071045 17.830150604248,18.4301509857178 16.9300575256348,19.7651691436768 16.6000003814697,21.4000015258789 16.9300575256348,23.0348339080811 17.830150604248,24.36985206604 19.165168762207,25.2699451446533 20.8000011444092,25.6000003814697 22.4348335266113,25.2699451446533 23.7698516845703,24.36985206604 24.6699447631836,23.0348339080811 25.0000019073486,21.4000015258789 24.6699447631836,19.7651691436768 23.7698516845703,18.4301509857178 22.4348335266113,17.5300579071045 20.8000011444092,17.2000007629395z M20.8000011444092,18.7000007629395L21.8509674072266,18.9121780395508 22.7091941833496,19.4908084869385 23.2878246307373,20.3490352630615 23.5000019073486,21.4000015258789 23.2878246307373,22.4509677886963 22.7091941833496,23.3091926574707 21.8509674072266,23.8878231048584 20.8000011444092,24.1000003814697 19.7490348815918,23.8878231048584 18.8908081054688,23.3091926574707 18.3121776580811,22.4509677886963 18.1000003814697,21.4000015258789 18.3121776580811,20.3490352630615 18.8908081054688,19.4908084869385 19.7490348815918,18.9121780395508 20.8000011444092,18.7000007629395z"/>

Output is:

How did I do it?

I used your data and transformed it by using the http://wpftutorial.net/GeometryTransformer.html.

Answer 4

Make sure you look at the existing Symbol icon types already. As an example we have a type for Camera:

<AppBarButton Icon="Camera" />

Answer 5

Hi Tim,

Yeah, I am actually writing a blog post demonstrating how to use a FontIcon or PathIcon when the existing SymbolIcon does not have a symbol you are looking for.  Just used a camera icon as an example :)

For now it seems the solution which Thomas gave will have to work.

Answer 6

Hi Jerrie,

great, looking forward to your blog post. :-)

In addition, take a look at this TechNet-Article I've written last month about new AppBar features in Windows 8.1:
