Then based on the value I either return a Red or Black solidColorBrush to draw the text with on the datagrid. In the ConvertFunction I am converting the value being sent in an object to an int. In this case I did not implement the ConvertBack function because I am using it to change the column color. The ConvertBack function is called when the data is being sent back to what the object is bound to. The convert function is called when the data is being displayed.

The interface defines 2 method Convert and ConvertBack. Color CType(objCConv.ConvertFromString('Green'), Color) Me. Public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture) ColorConverter() ' Retrieve a Color object from a string Dim objColor AS System.Drawing.

So rather than walk though writing the whole class step-by-step, we will just look at a few interesting Of a color as a location within a predefined three-dimensional space, there is little more to do than math in order to generate various color sequences.

There is no data-set to work with as, truly, the entire color cube concept is represented in the diagrams above. an existing bitmap and convert it into an icon with a transparent backcolor.-Dennis in Houston 'Ken Tucker MVP' wrote: Hi, Even when I save a icon with its back color as ansparent it shows up with a black background in windows explorer.

The spectrum of full intensity colors (that is, the rainbow) is represented by following the outside edges of the cube from red, to yellow, to green and around to magenta.Īnd since we have defined a three dimensional space we can find any sequence of colors between two colors by measuring angles and distances.Ĭreating a class to represent this concept of a RGB Color Cube is really little more than a collection of functions. The primary RGB and CMYK colors (red, green, blue, yellow, cyan, magenta, black, and white) exist at each corner of the cube: The furthest corner from black would be, or White. The blue axis to the right, and the green axis points upward from black. If we are facing the cube then, the red axis runs to the left, So we can define the RGB color space as a cube, 255 units on a side, with an origin at which represents the color Black. We can think of these R, G, and B values as being the axis of a threeĭimensional space in other words, the x, y, and z axis of a grid. These values are expressed as Bytes and are therefore limited in range to 0 through 255. The RGB Color CubeĪ color value in the RGB color space has three components the Red, Green and Blue intensity values. Spatially, we can construct a three-dimensional cube which represents all possible colors and can easily be traversed mathematically.

While any number of complex code solutions could be created to attempt to address this problem, if we think of the RGB color space Net framework does not give us any sophisticated solution for this. This canīe useful for coloring bars in a graph or generating a gradient around some specified color.

Declare a Function named 'IntegerToColor' This function should have the following: A single 32 bit integer. This example will be given in Visual Basic.Net. Net language of your choice, you can follow these steps to create a Function that will convert 32 bit integers into colors. Color Name: Color Red Green Blue AliceBlue : 240: 248: 255: AntiqueWhite : 250: 235: 215: Aqua : 0: 255: 255: AquaMarine : 127: 255: 212: Azure : 240: 255: 255.

Exceptions FormatException value does not correspond to the string representation of a color. Returns Object A Color that represents the converted text. Sometimes when you are designing a form, or creating some other kind of visual output, you'd like to generate an array of colors which may be shades of a single color or a discernible sequence of individual colors such as the spectrum of a rainbow.
