Detailed Description

Read DXF files into LibrePCB data structures.

Basically this is a wrapper around the third-party library "dxflib" to read DXF files and return the DXF objects as LibrePCB data structures. See documentation of dxflib about the exact capabilities of the reader itself.

Our wrapper currently supports the following data structures:

• Points
• Circles
• Lines (converted to polygons)
• Arcs (converted to polygons)
• Polylines (containing straight segments and arc segments)

Note that this class tries to read and apply the length unit defined in the DXF file. However, a DXF file is not required to specify the unit. If it is missing, the unit millimeters is assumed.

Constructor & Destructor Documentation

DxfReader() [1/2]

DxfReader ( )

noexcept

Default constructor.

DxfReader() [2/2]

DxfReader ( const DxfReader &  other )

delete

~DxfReader()

~DxfReader ( )

virtualnoexcept

Destructor.

Member Function Documentation

setScaleFactor()

void setScaleFactor ( qreal  scaleFactor )

inlinenoexcept

Set a custom scale factor.

All imported objects will be scaled with this factor (default is 1.0).

Parameters

scaleFactor

Scale factor.

Here is the caller graph for this function:

getPoints()

const QList< Point > & getPoints ( ) const

inlinenoexcept

Get all imported points.

Returns

List of point objects

getCircles()

const QList< Circle > & getCircles ( ) const

inlinenoexcept

Get all imported circles.

Returns

List of circle objects

getPolygons()

const QList< Path > & getPolygons ( ) const

inlinenoexcept

Get all imported lines, arcs and polylines (converted to polygons)

Returns

List of polygons

parse()

void parse

(

const FilePath &

dxfFile

)

Parse a DXF file.

Parameters

dxfFile

File path to the DXF to import.

Exceptions

Exception

if anything went wrong (e.g. file does not exist).

Here is the call graph for this function:

operator=()

DxfReader & operator= ( const DxfReader &  rhs )

delete
