DrawingML Example

DrawingML Example DrawingML graphic made by DrawingML is the markup language for vector graphics used in Office Open XML documents. Its main role is to render graphics elements of text, vector-based graphic forms, tables and diagrams. DrawingML is the third model of tables in Office Open XML (after models in WordprocessingML tables and SpreadsheetML) and is optimized for graphical effects like shadows and reflections that can be used in various graphic elements. It was created for use mainly by PresentationML language. You can create 3D effects by DrawingML for example, display various graphic elements through a flexible viewing angle. You can also create design motifs separated by a container DrawingML Office Open XML.These themes can be applied to graphic elements across all content within the container Office Open XML. The language DrawingML is not related to other vector graphics formats like SVG, but can be converted to DrawingML to include natively in a Office Open XML document. This is a different approach to the OpenDocument format, which uses a subset of SVG and vector graphics features in separate files. The dimensions of a graphic are specified in units DrawingML Metric English (the English English Metric Unit or EMUs). This unit is defined as 1/360.000 of an inch and thus there EMUs 914,400 in an inch and 12,700 EMUs per point. Was selected with the interests of unity that could use integers to represent most accurately the dimensions found in a document.Floating point operations can not adequately represent a fraction that is not the result of the sum of powers of two and that error is amplified when the fractions are added together several times resulting in a mismatch. Since one inch is 2.54 centimeters, or 127/50, the inch must be split into 127 for the inch and centimeter values become integers. To accurately represent two decimal digits, you need a splitter 100. To represent a point, you need a splitter 72, which also allows for divisions 2, 3, 4, 6, 8, 9, 12, 18, 24, and 36 to be exact. Multiplying these values results in 127 72 100 914,400 units per inch (the least common multiple of 228,600 would give values per inch and 90,000 per cm). According to Rick Jelliffe, programs and activities of standards (ISO, W3C, IETF), the EMUs are a rational solution to a set of design criteria.
