Before writing any parser, it is a good idea to try and get a good understanding of the format you are going to parse, so I looked around for some documentation and came across this link which is the specification for SVG:. The only point of interest here is that I had to set the XmlResolver to null to avoid getting exceptions while reading different SVG files I found online.

Each XML node is then parsed in the static method Group. AddToList Shape. All basic shapes are implemented in Shapes. LoadGroup creates a single DrawingGroup object which contains a child group for each of the SVG shapes, where each shape is converted into a Geometry and then wrapped in a GeometryDrawing object to set the fill and stroke style.

Each tspan element can be thought of as an individual text element, complete with style, stroke, and fill attributes, and for this reason, it is derived from the base shape. The rendering part is not designed for nested shapes except for groupsbut expect one shape, one geometry. TSpan is a bit different; each tspan element even if nested is added to the same GeometryGroup when the geometries are build.

Each geometry can have different attributes which are the attributes on the tspan shape itself. Instead of redesigning how the SVGRender creates the drawing by iterating though the shapes, I chose to attach the tspan element shape itself directly to each of the build geometries using attached properties and then 'extract' the shape from the geometry when creating the drawing. The SVG parser and render is still not complete, but it is in a state where it can read most 'simple' SVG files I have found online so far.

Of the chapters in the SVG Essentials book, the following chapters have been implemented:. I will continue working on this, and the next step is probably to add support for the text element. For text formatting, I had to use the low level GlyphRunas FormattedText does not provide the same control over letter and word spacing. I added a new class TextRender. BuildTextGeometry in TextRender. I finally got around to add basic support for tspan in the text element.Windows Presentation Foundation WPF is a free and open-source graphical subsystem similar to WinForms originally developed by Microsoft for rendering user interfaces in Windows-based applications.

WPF, previously known as "Avalon", was initially released as part of. NET Framework 3. WPF uses DirectX and attempts to provide a consistent programming model for building applications. These elements can then be linked and manipulated based on various events, user interactions, and data bindings. Microsoft Silverlight provided functionality that is mostly a subset of WPF to provide embedded web controls comparable to Adobe Flash.

It is released under the MIT License. Windows Presentation Foundation has become available for projects targeting the. NET Core framework, however, the system is not cross-platform and is still available only on Windows. Graphics, including desktop items like windows, are rendered using Direct3D. This allows the display of more complex graphics and custom themes, at the cost of GDI's wider range of support and uniform control theming.

It allows Windows to offload some graphics tasks to the GPU. This reduces the workload on the computer's CPU.

GPUs are optimized for parallel pixel computations. This tends to speed up screen refreshes at the cost of decreased compatibility in markets where GPUs are not necessarily as powerful, such as the netbook market. It is part of the. NET framework 3.

WPF's emphasis on vector graphics allows most controls and elements to be scaled without loss in quality or pixelizationthus increasing accessibility. With the exception of Silverlight, Direct3D integration allows for streamlined 3D rendering. In addition, interactive 2D content can be overlaid on 3D surfaces natively.

XAML is designed as a more efficient method of developing application user interfaces.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Does it produce a Drawing? An Image? A Grid? A Canvas?

A Path? A Geometry? In each case your technique will be different. In the examples below I will assume you are using your icon on a button, which is the most common scenario, but note that the same techniques will work for any ContentControl. This is like using an image or grid, but since a canvas has no fixed size you need to specify the height and width unless these are already set by the SVG converter :.

I found best way to me to use svg icon in WPF. I use sharpvector framework:. This shouldn't be necessary to use the Windows. SvgImageSource class, though. That is equivalent to using SvgImageSourceas follows:.

This can be worked around dynamically by creating a new SvgImageSource in the ImageOpened event for the base image:. You can use the resulting xaml from the SVG as a drawing brush on a rectangle.

Active Oldest Votes. Ray Burns Ray Burns You cannot use a single Canvas in multiple places in your UI because a Visual can only have one parent.

So you would typicaly use a template for this. I knew I couldn't use the same canvas twice directly which is why the answer was not yet accepted. Many thanks. So basically, for each of those elements - e.Submit your support inquiries via the DevExpress Support Center for assistance.

Developer Express Inc is proud to announce the immediate availability of its newest release, DevExpress v Built and optimized for desktop, web, and mobile developers alike With 40 categories and over products to choose from, DevExpress is honored to have been voted best in class 18 times in this year's Visual Studio Magazine Reader's Choice Awards To better support high DPI monitors, our design team just added vector icons to the gallery.

A cool feature of these vector images is that they can change colors based on your application theme. The Image Gallery is only available for properties shown in Smart Tag menus.

The Image Picker helps you specify images for properties that are not included in Smart Tag menus, for controls that are not visible in the designer, or for code-behind. Please feel free to leave comments below if you have any thoughts about the new SVG images or the standalone Image Picker. Your feedback is important to us! Stephen: Are you using the latest DevExpress version v If so, SVG images should appear correctly in Blend I've now asked you a couple of times - email me directly so we can address your issues.

There is already a designer under WinForms delivered. It works somehow, with God's help. But it works! Including partially your designers. Is there any reason these icons aren't all included in the default set there as well?This topic provides an overview of the WPF visual layer. It focuses on the role of the Visual class for rendering support in the WPF model. The Visual class is the basic abstraction from which every FrameworkElement object derives. It also serves as the entry point for writing new controls in WPF, and in many ways can be thought of as the window handle HWND in the Win32 application model.

The Visual object is a core WPF object, whose primary role is to provide rendering support. User interface controls, such as Button and TextBoxderive from the Visual class, and use it for persisting their rendering data. The Visual object provides support for:.

Hit testing: Determining whether a coordinate or geometry is contained within the bounds of a visual. However, the Visual object does not include support for non-rendering features, such as:. Visual is exposed as a public abstract class from which child classes must be derived.

The following illustration shows the hierarchy of the visual objects that are exposed in WPF. The DrawingVisual is a lightweight drawing class that is used to render shapes, images, or text. This class is considered lightweight because it does not provide layout or event handling, which improves its runtime performance. For this reason, drawings are ideal for backgrounds and clip art.

The DrawingVisual can be used to create a custom visual object. For more information, see Using DrawingVisual Objects. The Visual3D class is the base class for all 3D visual elements. The camera allows you to view the scene. The viewport establishes where the projection maps onto the 2D surface. The ContainerVisual class is used as a container for a collection of Visual objects.

The DrawingVisual class derives from the ContainerVisual class, allowing it to contain a collection of visual objects. A Visual object stores its render data as a vector graphics instruction list. Each item in the instruction list represents a low-level set of graphics data and associated resources in a serialized format. There are four different types of render data that can contain drawing content.

The DrawingContext allows you to populate a Visual with visual content. When you use a DrawingContext object's draw commands, you are actually storing a set of render data that will later be used by the graphics system; you are not drawing to the screen in real-time.A vector image is a geometric representation of an image. SVG is a common file format for vectors. Odds are you are here because you either have an SVG you want to convert or you want to create one. What you ultimately want to get is XAML something like this — a path with data.

You can then stick it into a canvas, viewbox, etc. If you want to create an SVG, there are a bunch of tools available. A nice free option is Inkscape. You can easily create an image or load one, then save it as an SVG. You can also export to XAML more on that in a moment. Note that the above image consists of only three lines. You can open it in your favourite text editor. If you were to open the file and scroll down, checkout the content below.

The data you want is in the d properties of the path. The simplest thing to do is copy and paste it out. Note that I had to keep the F1 in front of my paths. Note that you probably still have some cleanup to do.

XPS format is or was? You will often see it available as a virtual printer. Save it somewhere 3 Rename the file extension to. ZIP 4 Extract all the files in the zips.

Once you find the code you will be rewarded with some nice, clean code.Icons are very important in effective user interface design, which improves user experience with the software and establishes an intuitive connection between the software and its users.

We are mostly using image files.

Using image files. We can't use the same image for different scales, we have to maintain different sized versions for the same image, so the number of files and icon sizes are increased, also we need to crop the images in different sizes. And sometimes, images files cannot be displayed clearly. So, in order to overcome these problems, we can go for vector icons. Vector icons can be resized to any size without loss in quality of the image.

Also vector icons are stored as mathematical data. We can draw our own vector icons using popular vector drawing tools like InkscapeExpression Designor Adobe Illustrator. There are lot of tutorials and documentation is available for these tools, which will help to get started with these tools. After the designing of icons using these tools, you can copy the generated mathematical data for the icons, and use it in wpf applications.

For example, the below GIF shows how to get the mathematical data of drawn icon from Inkscape. If you don't want to create a new vector icon, you can use existing vector icons, you can get vector icons for free or you can get paid version of icons, there are lot of sites providing free vector icons, some of them below. Just download icons from above sites, each icon may have. Or you can get the icon data from the website itself, Material Design Icons provides the xaml version of icons in the website itself, see the below image.

The path node shown in the above images contains icon data, this will be used in xaml. And there is an another free tool available for vector icon design, i. WPF supports vector based images. Name it as Icons. Many icon design softwares and icon developing sites are providing free vector icons, we can get vector format for those icons, for example, refer to Material Design Iconsthey are providing icons in XAML format. Just copy path node of the XAML part of the icon.
