Now if you want to build a professional App, UI design and ease of operation are very important. UI design can use design tools such as Photoshop or AI. I previously learned that the WPF design tool Expression Blend can directly import PSD files or AI design files (of course not all features are supported). I recently researched it and spent a lot of trouble. Fortunately, Finally, the desired effect was achieved. The following is a step by step example to illustrate how to first use PS to build a vector graphic template, then use Expression Blend to import the PSD file, and obtain the Data value of PATH to build a beautiful UI for creating a cool personalized progress bar control.
1. Open Photoshop, create a new blank layer, and click on the PS pattern stamp tool:
##2. Select the brush you like (you can download free brushes from the website), as shown below:
After clicking on the appropriate location, as shown in the figure below.
3. Hold down CTRL, select the layer, switch to the Path panel, and click [Create working path from selection] button, as shown below:
##Pay attention to the picture above The red box button is [Create working path from selection]. After clicking, the following picture will appear:
4. This is the most critical step. Create a vector mask, switch to the layer panel, click the [Pen] tool, and select the [Create Vector Mask] item in the right-click menu on the graphic, as shown in the following figure:
Then you can see the effect of the picture below in PS, indicating that the creation is successful.
Save the PS file as a progress bar.PSD file for later use.
5. Open Expression Blend 4 to create a new WPF project, and then import the PSD file, as shown below:
##After the import is successful, you can copy the clip data of the graphic, this is Data value required by PATH in WPF.
Let’s create a cool WPF progress bar control.
6. Re-open the project in VS2010 and add a WPF custom control library, as shown below:
