brush

i have created some histogram with d3.js . I managed to change fill color of rect depending on the position of the brush . But i would like to change the color inside a rect . For example if the brush start is in the middle of the rect i would like to have my rect with two color. At the moment this is what i have : And this is what i would like to have : I have seen some examples like Here . I'm new to d3 and i try to understand the code. I see that they use clip-path that certainly hide the background bar when their is no brush and show them when their is one depending on the range of the

What is the best way to pick a random brush from the System.Drawing.Brushes collection in C#? If you just want a solid brush with a random color, you can try this: Random r = new Random(); int red = r.Next(0, byte.MaxValue + 1); int green = r.Next(0, byte.MaxValue + 1); int blue = r.Next(0, byte.MaxValue + 1); System.Drawing.Brush brush = new System.Drawing.SolidBrush(Color.FromArgb(red, green, blue)); For WPF, use reflection: var r = new Random(); var properties = typeof(Brushes).GetProperties(); var count = properties.Count(); var colour = properties .Select(x => new { Property = x, Index =

I have an 8x8 Image. (bitmap - can be changed) What I want to do is be able to draw a shape, given a Path and Paint object onto my SurfaceView . At the moment all I can do is fill the shape with solid colour. How can I draw it with a pattern. In the image you can see the brush pattern (The cross). It can be anything from a cross to a donut or an elf. How would I go about drawing this pattern background. I also eventually want to apply colours to it. So far, my theory is to create a clip area of the shape, and tile the bitmaps until area is covered, but this is extreme overkill in processing.

I am using d3.js, and I'm working on a brushed area chart by modifying this example . In addition to the x-axis changing based on the brush, I'd like chart's y-axis to be redrawn, based on the y-values of the data that fall within the brush (similar to the behavior of a Google Finance chart ). I have gotten the functionality working, but only in a way that enables the brush to be drawn in both x- and y-space. I did this by first adding a y scale to the brush variable: var brush = d3.svg.brush() .x(x2) .y(y2) .on("brush", brush); This makes brush.extent() return the following multi-dimensional

I need to add typical finger drawing to an app. (The usual.... choose colors, erase, thickness - just the usual you see in every app made.) It's hard to believe I have to program this from scratch, in this day and age? It's hard to believe there is not a common solution for this? All I could find is... https://github.com/levinunnink/Smooth-Line-View Review : that is a (beautifully written) example fragment of a few lines of code being how to draw with a path, with a good smooth result. It works perfectly, but it's just for drawing one "path." For example, you can't make a drawing with more

I have a class X there are some data: private string yyy; public string YYY { get { return yyy; } set { yyy= value; NotifyPropertyChanged("YYY"); } } private SolidBrush color; public SolidBrush Color { get { return color; } set { color= value; NotifyPropertyChanged("Color"); } } My Data Grid bind to this class like this: <DataGrid x:Name="dg1" ItemsSource="{Binding}" AutoGenerateColumns="False"> <DataGrid.Columns> <DataGridTemplateColumn Header="yyy" > <DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding YYY}" Foreground="{Binding Color}"/> </DataTemplate> <
