| System from the beginning of the design on canvas, edit, print output all the links are fully customizable as needed, on the development of CAD system is concerned, you can easily set:  . CAD-specific mapping mode. . Using millimeters, centimeters, meters, feet, inches and other mapping units. . Canvas coordinate origin can be set anywhere in the canvas. . Canvas background color and graphics colors can be set to any color, but when the printed output shows only a white background. . You can extend around the first center in a way to draw any graphics. . Canvas size freely defined. . Improve the printing control system built-in functions, without writing a single line of code to select the printer, set the print paper, control orientation, set page margins and so on. . Support multi-layer display. . Support the drawing auxiliary lines. . Support the label. . Supports rotate text at any angle, and the WYSIWYG text entry. . Using shared GDI device that will extend the performance to the extreme, can accommodate tens of thousands in the same pixel in the canvas at the same time to complete editing. . Supports tagging, tagging can be horizontal, vertical mark, any mark, and the radius of the mark. And all labeling and flexible module can be expanded as needed. . Full support for the creation of complex graphics can be any combination of simple graphics to complex composite graphics. . Support any complex polygon operations, including the intersection, and would like to, take over, so the joint operation. . Support the capture function, you can automatically capture the geometry of the endpoint, center, center of the circle and so on. . Support the line and arc hybrid editing, graphics can be directly manipulated for a certain period, which can be straight lines and arcs in the freedom of conversion. . Full support for Undo / Redo, can be set to any multi-level Undo / Redo operation. . Can increase the canvas plug and play any graphics on the new property values, increase property values and the new automatic support for modifying the UNDO / REDO. . RTF support complex text editing and direct printing of direct output. . Can any graphics on the canvas to move, rotate, scale, distortion, distorted, arranged so advanced operation. . To support a large canvas scaling. . Can be pushed through the mouse flat canvas. . Support centimeters, millimeters, feet, inches and other scale ruler. . Can be directly imported bmp, wmf, emf, jpeg, gif, tga, pcx, png, mng and other image files. . Full support clipboard can be free to copy and paste graphics. . Be free to adjust the arrangement of canvas graphics level. . Provides thumbnail preview function, and can preview the image through the rectangular box, adjust the display position of the current canvas. . Ocx control to provide consistent functionality for easy web deployment or other languages, platform developers call the same functions. . Support multi-layer editing and display, as shown below. . support to import any external DXF files. . support to import any external SVG file. . multi-layered rendering layer. . support for distance measurement and area measurement. . support for advanced multi-dimension line drawing. . supports two o'clock, three draws and oval garden features. 37. The most important is that we will rigorously tested all of these high-quality Visual C + + source code available to you, the source code also includes the design of the control ocx source code. |
