SynopsisModifies the attributes of an existing region. Syntaxset_region([id,] values) Description
The set_region command sets the specified attributes to the provided values. The modified region becomes current. Multiple regions may be modified with a single command by setting the currency to "all". Customizing the RegionThere are several attributes that control the characteristics of regions. The set_region command may be used to modify the attribute values of an existing region at any time during a ChIPS session. See "ahelp attributes" and "ahelp setget" for more general information. If multiple attributes are being set simultaneously and one of them fails, the entire command will fail and the region will not be modified. The attributes associated with regions are:
Advanced FunctionsThe module of advanced ChIPS functions contains other commands for setting attribute values (refer to "ahelp chips" for information on loading the module): set_region_depth set_region_edgecolor set_region_edgestyle set_region_edgethickness set_region_fill set_region_fillcolor set_region_opacity Example 1chips> set_region(['edge.color','plum', 'edge.style', 'dot']) Using attribute/value pairs, set the region edge color to plum and the edge stipple pattern to dot. Example 2
chips> settings = ChipsRegion()
chips> settings.fill.color = 'blue'
chips> settings.edge.thickness = 2
chips> set_region('reg1',settings)Populate the "settings" structure with attribute values, then use it to set reg1 edge to be blue with a thickness of 2. Example 3chips> class properties: pass chips> p = properties() chips> p.edge = ChipsRegionEdge() chips> p.fill = ChipsRegionFill() chips> p.edge.color = 'red' chips> p.fill.color = 'blue' chips> set_region(p) Create a user-defined structure with edge.color and fill.color fields. Use the structure to modify the values of the current region. Example 4chips> class properties: pass chips> p = properties() chips> p.depth=50 chips> set_region(p) Create a user-defined structure with depth field. Use the structure to modify the values of the current region. CHANGES IN CIAO 4.1Pattern fill optionsThe attribute "fill.style" replaces the "fill.visible" attribute. There are multiple fill styles available, instead of a boolean filled/not filled. A value of 0 (chips_nofill) is equivalent to fill.visible=0; a value of 1 (chips_solidfill) is equivalent to fill.visible=1. See the Fill Patterns section of "ahelp chipsopt" for the full list of pattern styles. Default color not changing for printingThe histogram and region fill colors when set to default were not being changed from a display foreground color to a postscript foreground color.
