Member Function Documentation
◆ copy()
|
inlinevirtual |
Get a new copy of entity.
Implements MyDXFEntity.
◆ debug_print()
|
virtual |
Print debugging information to stream os.
Implements MyDXFEntity.
◆ end()
|
inlinevirtual |
Get end point of path entity.
Implements MyDXFPathEntity.
◆ explode()
|
virtual |
Explode into entities.
Break entity into atomic entities and tranform entities them with tranformation t. Add the tranformed entities to the database ent.
Implements MyDXFEntity.
◆ geom_same()
bool MyDXFLine::geom_same | ( | const MyDXFLine & | line, |
double | eps = 1.0e-6 |
||
) | const |
Check if two entities are geometrically same.
Checks if entity a is the geometrically same as entity b within error limit eps.
◆ get_bbox()
|
virtual |
Return bounding box of entity.
Implements MyDXFEntity.
◆ get_type()
|
inlinevirtual |
Get entity type.
Implements MyDXFEntity.
◆ plot()
|
virtual |
Plot entity with cairo.
Plot the entity using the transformation from from the object space to cairo coordinates. The visible range is specified by range (xmin,ymin,xmax,ymax) in cairo coordinates.
Implements MyDXFEntity.
◆ ray_cross()
|
virtual |
Check for ray crossing.
Check if ray going from point (x,y) downwards (negative y direction) crosses the entity. Return 1 if crosses odd number of times and 0 if even number of times. Return 2 in case of exact crossing at boundaries. This function is used as a subroutine to inside_loop().
Implements MyDXFPathEntity.
◆ rotate_z()
|
virtual |
◆ scale()
|
virtual |
Scale entity by factor s.
Implements MyDXFEntity.
◆ set_end()
|
virtual |
Set end point of path entity.
Implements MyDXFPathEntity.
◆ set_start()
|
virtual |
Set start point of path entity.
Implements MyDXFPathEntity.
◆ start()
|
inlinevirtual |
Get start point of path entity.
Implements MyDXFPathEntity.
◆ translate()
Translate entity by dx.
Implements MyDXFEntity.
◆ write()
|
virtual |
Write dxf file to stream.
Implements MyDXFEntity.
