Set Marker Size
Purpose
The Set Marker Size function specifies the size of subsequently rendered markers.
Syntax
| Opcode format | Opcode
[ASCII] (Hex) |
Operand Format | Comments |
| Single-byte, readable operand | [S] (53) | [<ws>]<ISize> | Scales subsequent markers |
| Single-byte, binary operand | [s] (13) | <ULSize> | Scales subsequent markers |
Scale Selects the size, in logical coordinate units, to which subsequent marker glyphs are rendered.
Details
When a glyph is recorded into the glyph table with the Define Marker Glyph opcode, a unit parameter is specified. The Set Marker Size operation scales all of the geometric primitives in subsequent marker glyphs by a factor such that a line, originally of unit length, is scaled to a size in logical units.
Default
The default marker size is zero logical coordinate units (always rendered as a single screen pixel) and is equivalent to
