| Method |
Comment |
| baseMeasurement:
anObject |
Save
the value of baseMeasurement. baseMeasurement is the units that define the
page. These units may be #pixels - based on the current baseResolution
setting #inches #mm |
| baseResolution:
anObject |
Save
the value of baseResolution. This sets the resolution to be used for all
pixel measurements. This defaults to 600 @ 600 dpi. This does not affect
the resolution of the printer which is set using the printer setup in the
normal way. All actual calculations are converted from baseResolution to
printer resolution before use. |
| baseScale:
anObject |
Save
the value of baseScale. Currently, this is not implemented. |
| currentArrowheads |
Return
the value of currentArrowheads. arrowheads can be: #none = no arrowheads
#start = arrowhead at the start of the line #end = arrowhead at the end of
the line #both = arrowheads at both ends of the line |
| currentArrowheads:
anObject |
Save
the value of currentArrowheads. sets any value other than #start, #end and
#both to #none |
| currentBox:
anObject |
Save
the value of currentBox. currentBox defines the extent of any box or word
wrapping draw where the extent is not explicitly defined. |
| currentCircleOrientation:
anObject |
Save
the value of currentCircleOrientation. This is not implemented in the
current Turtle version. This will be used to enable circle drawing to be
based on one of the following: #left - draw in a box with the origin as
the left hand top corner of the bounding box; #right - draw in a box with
the origin as the right hand top corner of the bounding box; #center -
draw in a box with the center point as the center of the bounding box; |
| currentColor:
anObject |
Save
the value of color. This setting is used for all operations involving
drawing - text, lines, circles, boxes, polygons. This uses the current
palette (see Visibility Color for instructions on changing the palette) of
16 colours. |
| currentDashes |
Return
the value of currentDashes |
| currentDashes:
anObject |
Save
the value of currentDashes. Currently on the following patterns are
accepted: #( 4 4 ) #( 24 8 ) #( 12 8 4 8 ) #( 12 4 4 4 4 4 ) |
| currentDashStyle |
Return
the value of currentDashStyle. |
| currentDashStyle:
anObject |
Save
the value of currentDashStyle. Should be true false #none #lineSolid #lineOnOffDash
or #lineDoubleDash - see CgValues for explanation. true will be converted
to #lineOnOffDash false will be converted to #none any incorrect value
will be converted to #none |
| currentFill:
anObject |
Save
the value of currentFill. Used to define the fill policy for any box or
circle operation where the fill policy has not been set explicitly. May be
true or false - true = filled box/circle. |
| currentFont:
anObject |
Save
the value of currentFont. Sets the current font to be used for all text
operations. The content should be a font which exists as an entry in the
VisibilityPrint fontArray. |
| currentImageBox:
anObject |
Save
the value of currentImageBox. This defines the extent of the bounding box
for any subsequent Image drawing. |
| currentImageJustification:
anObject |
Save
the value of currentImageJustification. Sets the justification of the
Image within the bounding box. This follows Visibility Color conventions
and allows #normal #stretch #left #right or #tiled |
| currentLineWidth:
anObject |
Save
the value of currentLineWidth. |
| currentLocation |
Answers
the current Turtle location. |
| currentShadowWidth:
anObject |
Save
the value of currentShadowWidth. |
| currentTextJustification:
anObject |
Save
the value of currentTextJustification. This follows Visibility Color
conventions and allows #left #right #center #decimal (only for numbers -
otherwise this will result in #right |
| debugFile:
aString |
Save
the value of debugFile. When set to not Nil, this will be used as the path
for a text file used to store the logging stream generated by the Turtle.
The file name has the format yourFileNameHHMMSS.log where yourFileName is
the supplied string in aString. |
| debugToTranscript:
anObject |
Save
the value of debugToTranscript. When set to true, this will enable output
of the logging stream generated by the Turtle to the Transcript. The
default setting is false. |
| defaultAngle:
anObject |
Save
the value of defaultAngle. If not set, the value is set to 0 |
| defaultArrowheads:
anObject |
Save
the value of defaultArrowheads. This is the setting used if
currentArrowheads is nil. |
| defaultBox:
anObject |
Save
the value of defaultBox. This is the setting used by currentBox if
currentBox is nil. |
| defaultCircleOrientation:
anObject |
Save
the value of defaultCircleOrientation. This is the setting used by
currentCircleOrientation if currentCircleOrientation is nil. |
| defaultColor:
anObject |
Save
the value of color. This setting is used for all operations involving
drawing - text, lines, circles, boxes, polygons. This uses the current
palette (see Visibility Color for instructions on changing the palette) of
16 colours. This is the setting used by currentColor if that has not been
set. The value of defaultColor is set to 0 if not set. |
| defaultDashes:
anObject |
Save
the value of defaultDashes. |
| defaultDashStyle:
anObject |
Save
the value of defaultDashStyle. |
| defaultFill:
anObject |
Save
the value of defaultFill. This is the setting used by currentFill if
currentFill is nil. |
| defaultFont:
anObject |
Save
the value of defaultFont. This is the setting used by currentFont if
currentFont is nil. |
| defaultImageBox:
anObject |
Save
the value of defaultImageBox. This is the setting used by currentImageBox
if currentImageBox is nil. |
| defaultImageJustification:
anObject |
Save
the value of defaultImageJustification. This is the setting used by
currentImageJustification if currentImageJustification is nil. |
| defaultLineWidth:
anObject |
Save
the value of defaultLineWidth. |
| defaultShadowWidth:
anObject |
Save
the value of defaultShadowWidth. |
| defaultTextJustification:
anObject |
Save
the value of defaultTextJustification. This is the setting used by
currentTextJustification if currentTextJustification is nil. |
| newOrigin:
aPoint |
Sets
and answers the origin of the page as being aPoint. From now on all moves
will be made relative to the new origin. currentAngle is reset to 0 and
the current location is set to 0 @ 0 |
| pageSize |
Answers
the currently defined page size in baseMeasurement units. |
| pageSize:
aPoint |
Sets
and answers the current page size to be aPoint. aPoint should be defined
in the units as set by the baseMeasurement setting. |
