Text to ascii art converter tool What is a text to ascii art converter? This tool takes text as input and converts it to ASCII art. You can choose any FIGlet font to draw the ASCII art with either from a collection of 148 preloaded fonts, or by defining a URL to import the font from. ASCII Converter enables you to easily convert ASCII characters to their hex, decimal, and binary representations. In addition, base64 encode/decode binary data. As you type in one of the text boxes above, the other boxes are converted on the fly.
Convert text into ASCII number format. For example A is 065.
Text in a computer is stored as numbers called ASCII numbers with each letter having its own number. Input text to convert to these ASCII numbers. ASCII is short for American Standard Code for Information Interchange. With applications in computers and other devices that use text, ASCII codes represent text. Based on the English alphabet, ASCII is a character-encoding scheme.
ASCII was originally developed from telegraphic codes. Computers can only understand numbers, and ASCII codes are numerical representations of characters that a computer can understand.
Examples of characters are a, 1,. For example, 097 is the ASCII numerical representation of the character a. ASCII covers over 100 characters with some of these characters being control characters that control how text appears. Work on ASCII began in the 1960’s through a committee of the American Standards Association. Many of today’s character-encoding schemes are based on ASCII, plus they include additional characters.
At one time ASCII was used on the World Wide Web as the most commonly used character encoding. If you prepare a text in ASCII format, you will get plain text with no format such as bold, and any computer can understand the format.
Other schemes such as HTML cover formatting.
Usage. The input file is an ASCII-formatted text file. The structure of the ASCII file consists of header information containing a set of keywords, followed by cell values in row-major order. There are two variations of the structure of the ASCII file.
One identifies the origin by the coordinates of the lower left corner of the lower left cell, the other as the center of the lower left cell. The format of the file in general is: NCOLS xxx NROWS xxx XLLCORNER xxx YLLCORNER xxx CELLSIZE xxx NODATAVALUE xxx row 1 row 2. Row n The definitions of the keywords are as follows:. NCOLS and NROWS are the number of columns and rows in the raster defined by the ASCII file. XLLCORNER and YLLCORNER are the coordinates of the lower left corner of the lower left cell.
You can also use XLLCENTER and YLLCENTER to specify the origin by the coordinates of the center of the lower left cell. CELLSIZE is the cell size of the raster. NODATAVALUE is the value that is to represent NoData cells. Cell values should be delimited by spaces. No carriage returns are necessary at the end of each row in the ASCII file. The number of columns in the header is used to determine when a new row begins.
An example of an ASCII raster file is: NCOLS 480 NROWS 450 XLLCORNER 378922 YLLCORNER 4072345 CELLSIZE 30 NODATAVALUE -32768 43 2 45 7 3 56 2 5 23 65 34 6 32 54 57 34 35 45 65 34 2 6 78 4 2 6 89 3 2 7 45 23 5. The NODATAVALUE is the value in the ASCII file that will be assigned to NoData cells in the output raster. This value is normally reserved for those cells whose true value is unknown. When the output raster is created, a system-generated NoData value will be used in place of the NODATAVALUE. The number of cell values contained in the file must be equal to the number of rows times the number of columns, or an error will be returned. The output data type can be either float or integer. Once the output raster has been created, use the tool to give it the appropriate coordinate system.
Certain may apply to this tool. For the environment settings, only the Build pyramids setting is honored.
The remaining Pyramid environment settings are ignored. More control over the nature of the pyramids can be obtained in a subsequent step by using the tool. For the environment settings, only setting the Calculate Statistics parameter to None is supported (the other parameters are ignored). This is only for raster formats other than Esri Grid. For the environment settings, only the type of compression may be honored.
This is only for raster formats other than Esri Grid.
