A system and method for utilizing a drawing specification for motion control. A plurality of elements in the drawing specification may be automatically identified. The elements may include one or more lines, polygons, arcs, splines, alphanumeric characters, and/or ellipses. Additionally, the drawing specification may be a drawing or digital drafting file, such as an AutoCAD file, among others. An order of the plurality of elements may be automatically determined according to a sorting algorithm. The sorting algorithm may include a geometric and/or radial sorting algorithm. The radial sorting algorithm may specify the order of the elements according to nesting and/or distance from the center of the drawing specification. Code may be automatically generated for implementing motion control based on the identified elements and the determined order. The generated code may include inserted operations such as raise, lower, and move operations, among others.

System and method for utilizing drawing specifications for use in motion control. Elements in a drawing specification may be automatically identified. The drawing specification may include one or more drawings, digital files, AutoCAD drafting files, and/or drawing specifications. Code may be automatically generated based on the one or more elements in accordance with a schema, and may include instructions in a data representation language, e.g., a markup language such as HTML, XML, etc. The automatically generated code may include move operations, e.g., arc, contour, line, raise, lower, halt, begin, etc., with associated parameters, e.g., move constraints, digital outputs, position compares, etc. The schema may include one or more blocks, each associated with a portion of the drawing specification, one or more elements, each associated with a block, one or more move operations, each associated with an element, and one or more parameters, each associated with a move operation.

A plurality of operator interface controls for use in a run-time operator interface application for executing one or more test executive sequences is described. Each operator interface control may have associated functionality for managing execution of a test executive sequence and/or functionality for displaying information regarding execution of a test executive sequence. One or more of the operator interface controls may be included in a run-time operator interface application, which may aid the user in easily creating the run-time operator interface application.

A system and method for enabling a property browser to display properties of sub-objects of a control, such as an ActiveX control. The system and method further enables a user to manipulate properties of sub-objects of the control. The method determines the top level interface of the control and displays the top level properties at the top level interface in a property browser. The property browser also displays an indication of properties which are sub-objects, i.e., properties which themselves have properties. This indicator is typically a conventional plus sign which indicates further elements are available in a hierarchy tree of elements. When the user subsequently selects a property which is a sub-object, the method operates to read the interface of the sub-object property from the type library and then display further top level properties of the interface as necessary.

A system and method for dynamically substituting colors in graphic images. The color substitution method receives a color to be replaced within the graphic image (Cr) and a new color (Cn). The method also receives a hue variance % value, which indicates the degree of hue variance for which a color substitution is performed. The method then converts the color to be replaced (Cr) to hue, luminance and saturation components (Hr, Lr, Sr), and converts the new color (Cn) to hue, luminance and saturation components (Hn, Ln, Sn). The method also computes a luminance difference Ld&equals;Ln&minus;Lr. Then, for each color element, e.g., each pixel or color command, the method performs a color substitution operation to replace one or more current colors in the graphic image with the new color. The color substitution operation for each color element compares the hue component Hc of the current color (Cc) of a current pixel in the graphic image and determines if Hc matches Hr within the specified hue variance. The method maintains the current color of the current color element unchanged if Hc does not match Hr within the specified hue variance, since the color of the current color element is not sufficiently close to the color desired to be changed. If Hc matches Hr within the specified hue variance, then the method sets the value of Hc to the value of Hn and sets the value of Lc to Lc&plus;Ld in response to determining that Hc matches Hr. After the values of Hc and Lc have been changed appropriately, the method converts the new Hc and Lc values and the Sc value, back to an rgb format to produce a new color for the current color element. This new color is then stored for the respective color element, thereby effecting a color substitution for the respective color element.
