For drawing objects, attributes are stored in a database and linked to selected drawing objects.Ī layer in AutoCAD. For features, attributes can be stored with the geometry, or stored in a database and joined to feature data. Tabular data that describes the characteristics of feature(s) or drawing objects, for example, the number of lanes and pavement-type belonging to a road. As-built data incorporates any field markups on the original construction drawings.ĭata that depicts the original plan for construction or installation, for example, the design for a new electric service or a new pipe installation.
Examples of area topologies are parcels, land use, land cover and political boundaries.ĭata that depicts the final installed configuration (physical or functional). In an enterprise industry model, the polygons are generated automatically from the surrounding line strings. Area topologies contain line strings and centroids. In an industry model, a description of spatial relationship between geographic area features. Annotation templates are stored as specially named blocks within your drawing. The information to display in an annotation and the layout of that information. Specially created blocks containing attributes with Map expressions assigned to the attribute properties. To annotate geospatial features, use a label.
The location on a drawing object that determines the position of any annotation attached to that object.Ī way to display related values on a drawing object. With the color picker, you can choose any color you want and get tints and shades for that specific color.An annotation block used to indicate adjacent tiles. If you want more control, you can check out our other tool: the RGBA Color Picker. Our tool automatically adds tints and shades to the randomly generated color, so you don't have to worry about it! This can be done by adding white (tint) or black (shade) to the color. The purpose of adding a tint or shade is to make the color more pleasant, either lighter or darker. Tints and Shades are colors that are used to lighten or darken other colors. Then, convert each channel's integer value into a 2 character hexadecimal number (if it's a single character number, prepend a "0") and concatenate them to form the random hexadecimal color value.įor example, if the Red channel value is 25, the Green channel value is 255, and the Blue channel value is 7, the hexadecimal color value would be #19FF07. Random Hex (Hexadecimal) Colorįirst, generate a random RGB color as described above.
This gives us 3 numbers in total and therefore the RGB color. Generate 2 more random integers between 0 and 255 and make them the Green and Blue channel values respectively. Let this be the value of the Red channel of the color in RGB Color Space. This function rounds down the number to the nearest integer.įor example, if the number is 25.6, the result will be 25. To do this, we use the Math.floor() function. Next, we need to convert this number to an integer value. We then multiply this number by 256 to get a number between 0 (inclusive) and 256 (exclusive).įor example, if the number generated is 0.1, the resulting number will be 25.6. In JavaScript, this can be done by using the Math.random() function which returns a random number between 0 (inclusive) and 1 (exclusive). To generate a random RGB color, first generate a random number between 0 and 255. Once you like a color, select and copy its value from the column on the right, in the color space of your choice (currently supports Hex, RGB, RGBA, CMYK, HSL, HSV, LAB and more.) The Algorithm Random RGB Color To use the tool, simply click on the big "Generate" button repeatedly, until you find a color you like. This tool is easy to use and doesn't require downloading any additional software. One may want to generate colorful backgrounds or foregrounds, they might be looking for fun color palettes in which to design their next project, and one might be playing around with various styles of geometric art and wants some more interesting shapes.įor these reasons I have written a small tool that generates random colors. There are a variety of reasons for generating random colors.
