PEXMarkers2D(3) — Subroutines

Name

PEXMarkers2D - 2D Markers Primitive

Synopsis

void PEXMarkers2D(Display ∗display, XID resource_id, PEXOCRequestType req_type, unsigned int count, PEXCoord2D ∗points)

Arguments

displayA pointer to a display structure returned by a successful XOpenDisplay call.

resource_idThe resource identifier of the renderer or structure.

req_typeThe request type for the output command (PEXOCRender, PEXOCStore, PEXOCRenderSingle or PEXOCStoreSingle).

countThe number of points.

pointsAn array of points specifying marker locations.

Returns

None

Description

This function creates a 2D markers output primitive.

This function is like PEXMarkers, except that the vertices consist of only x- and y-components. The z-component is assumed to be zero. This primitive is two-dimensional only in that the z-components are implied. Geometry transformations are still carried out in three dimensions.

Data Structures

See the PEXStructuresman page.

Errors

BadPEXRenderer
The specified renderer resource identifier is invalid.

BadPEXStructure
The specified structure resource identifier is invalid.
