Public Types inherited from Detailed Description
This class represents Hatch entities in an OdDbDatabase instance.

- TD_Db
- Remarks
Loops must be closed, simple, and continuous. They must be self-intersecting itself only at their endpoints. Their start points and end points must coincide. The outer loops must be appended before all of their inner loops.
Teigha provides limited validation of the hatch boundary in order to maintain API efficiency and performance.

patType [in] Pattern type. patName [in] Pattern name. angle [in] Pattern angle. scale [in] Pattern scale. pat [in] Pattern definition (as in PAT file) basePt [in] Base point.
- Remarks
- patType must be one of the following:
Value kUserDefined 0 kPreDefined 1 kCustomDefined 2
patName is ignored for patType == kUserDefined; appearance is defined by setPatternAngle(), setPatternSpace() and setPatternDouble().
◆ setPatternAngle()
| void OdDbHatch::setPatternAngle | ( | double | angle | ) |
Sets the pattern angle for this Hatch entity (DXF 52).
- Remarks
- All angles are expressed in radians.
◆ setPatternDouble()
| void OdDbHatch::setPatternDouble | ( | bool | isDouble | ) |
Sets the pattern double flag for this Hatch entity (DXF 77).
- Parameters
-
isDouble [in] Sets the pattern double flag if true, clears it otherwise.
- Remarks
- Setting the pattern double flag causes a second set of lines, at 90° to the first, for kUserDefined hatch.
◆ setPatternScale()
| void OdDbHatch::setPatternScale | ( | double | scale | ) |
Sets the pattern scale for this Hatch entity (DXF 41).
- Parameters
-
scale [in] Pattern scale.
◆ setPatternSpace()
| void OdDbHatch::setPatternSpace | ( | double | space | ) |
Sets the pattern spacing for this Hatch entity (DXF 41).
- Parameters
-
space [in] Pattern spacing.
- Remarks
- Pattern spacing is the distance between parallel lines for kUserDefined hatch.
◆ setPixelSize()
| void OdDbHatch::setPixelSize | ( | double | pixelSize | ) |
Sets the pixel size for intersection and ray casting.
- Parameters
-
pixelSize [in] Pixel size.
◆ setRawPattern()
| void OdDbHatch::setRawPattern | ( | OdDbHatch::HatchPatternType | patType, |
| const OdString & | patName, | ||
| double | angle, | ||
| double | scale, | ||
| const OdHatchPattern & | pat | ||
| ) |
Sets the pattern data for this Hatch entity directly, bypassing OdHatchPatternManager (DXF 76 and DXF 2).
- Parameters
-
patType [in] Pattern type. patName [in] Pattern name. angle [in] Pattern angle. scale [in] Pattern scale. pat [in] Pattern definition (already scaled and rotated)
- Remarks
- patType must be one of the following:
Value kUserDefined 0 kPreDefined 1 kCustomDefined 2
patName is ignored for patType == kUserDefined; appearance is defined by setPatternAngle(), setPatternSpace() and setPatternDouble().
- Remarks
- angle and scale are not applied to the pattern.
◆ setSeedPointAt()
| void OdDbHatch::setSeedPointAt | ( | unsigned | seedIndex, |
| OdGePoint2d & | point | ||
| ) |
Sets the specified seed point for this Hatch entity (DXF 10).
- Parameters
-
seedIndex [in] Seed point index. point [in] Seed point.
◆ setShadeTintValue()
| void OdDbHatch::setShadeTintValue | ( | double | luminance | ) |
Sets the luminance value for this Hatch entity.
- Parameters
-
luminance [in] Luminace value. [0.0 .. 1.0]
If the gradient is using oneColorMode, this function sets the luminance value applied to the first color.
◆ subClose()
|
virtual |
Called as the first operation as this object is being closed, for database -resident objects only.
- Remarks
- This function is notified just before the current open operation is to be closed, giving this function the ability to perform necessary operatons.
When overriding this function:
1) If the OdDbObject's state is incorrect, throw exception.
2) Call parent class's subClose().
3) If other actions are required before close, do them.
The default implementation of this function does nothing. This function can be overridden in custom classes.
Reimplemented from OdDbObject.
◆ subExplode()
|
virtual |
Reimplemented from OdDbEntity.
◆ subGetClassID()
Reimplemented from OdDbEntity.
◆ subGetGsMarkersAtSubentPath()
|
virtual |
Reimplemented from OdDbEntity.
◆ subGetSubentPathsAtGsMarker()
|
virtual |
Reimplemented from OdDbEntity.
◆ subGetTransformedCopy()
|
virtual |
Reimplemented from OdDbEntity.
◆ subSetDatabaseDefaults()
|
virtual |
Called by setDatabaseDefaults() after the values are set.
- Parameters
-
pDb [in] Pointer to the database whose default values are to be used. doSubents [in] Set to true if subentities should be processed
- Remarks
- If pDb is null, the database containing this entity is used.
This function allows custom classes to inspect and modify the values set by setDatabaseDefaults.
The default implementation of this function returns eNotApplicable. This function can be overridden in custom classes.
- Remarks
- This function is not intended to be called by the user.
