Verb CFG.displayFracDialog
Syntax CFG.displayFracDialog( [fractal] )
Parameters fractal is an optional parameter. For non-fractal target windows, this string specifies the name or ID of the fractal data to edit.
Action Displays the dialog box for the target's fractal.
Notes If the target is a fractal, the parameter "fractal" is ignored. The data used in the dialog box is from the target's fractal type and data.
For non-fractal targets, if "fractal" is specified, the global data for that fractal type is edited. Otherwise, the data for the fractal type specified in the New Parameters Window is displayed.
If CFG dialog display is disabled, this function will not display anything. It simply returns True.
This command cannot be used when the target window is building a fractal.
See Also CFG.enableDialogs

See Also CFG.enableDialogs
CFG.getPrefs
CFG.setPrefs
Verb CFG.enableDialogs
Syntax CFG.enableDialogs( enable )
Parameters enable is a Boolean indicating whether or not to enable alerts.
Action Enables or disables alerts and dialog boxes. This is useful if user interaction is not desired.
Returns Boolean indicating the previous state of CFG.enableDialogs (true for enabled, false for disabled).
Examples CFG.enableDialogs( false )
» true
The alerts are now disabled as false was passed in. Prior to this call, the alerts were enabled as indicated by the return value of true.
Notes Use this command very carefully! CFG does not distinguish between commands directly from the user and commands from scripts. If user interaction is disabled, it will stay that way until re-enabled by this command.
During the time that alerts and dialogs are disabled, the only alerts or dialogs displayed are ones due to errors.
If a dialog or alert is suppressed, the program will proceed as if the user chose the default dialog response.
Exception: if the default action may require user interaction, then the alternative action is chosen (example: the default for "Save Changes" is "OK", but since the user may need to enter the path, "Don't Save" would be chosen).
If the alerts were disabled, make sure they are re-enabled before exiting the script.
See Also None
Verb CFG.errorString

Verb CFG.getDepth
Syntax CFG.getDepth()
Parameters None
Action Get the target's color depth (bits per pixel).
Returns An integer with the number of bits per pixel. Valid responses are -1, 4, 8, 16, and 32.
Examples CFG.getDepth()
» 8
CFG.getDepth()
» 32
Notes If the target is not a fractal, the default depth for a new fractal is returned. This information is displayed in the New Parameters Window.
A response of -1 (CFG.const.depthDeep) means to use the color depth of the deepest monitor attached to the system. Thus, if a computer has two monitors, one set to 4 bits / pixel and the other to 16, a CFG.getDepth of -1 means to use the 16 bit depth.
The depth is actually a field of the preferences. However, since it is unwieldy to handle the preferences structure just to modify the fractal color depth, this function and CFG.setDepth were created.
See Also CFG.displayPrefsDislog
CFG.getPreferences
CFG.setDepth
CFG.setPreferences
Verb CFG.getFilePath
Syntax CFG.getFilePath()

Action Get the PICT data for the current selection.
Returns 'PICT' data for the current selection or false if no selection or an error occurred.
Examples CFG.getPICT()
» /PICT DATA/
CFG.getPICT()
» false
Nothing was selected, so false was returned.
Notes The target window must be a fractal window.
The target must currently have a selection. This selection will be the PICT information which is returned.

» { 2, 3, 10, 20 }
The current scroll positions (h,v) are (2,3) while the maximum are (10,20).
Notes The target cannot be the New Parameters Window as it does not have a scroll region.
A value of -1 indicates no scroll information is available for that parameter. For example: the help window would return a -1 for r.left and r.right since it has no horizontal scroll bar.
The minimum scroll setting is 1.
See Also CFG.getWindowRect
CFG.scrollWindow
Verb CFG.getSelection
Syntax CFG.getSelection()
Parameters None
Action Retrieves the target's current selection.
Returns Rectangle with the selection.
Examples CFG.getSelection()
» { 0, 0, 640, 480 }
Notes This verb should not be applied to the New Parameters Window as it cannot have any selections.
For fractal windows, the rectangle is the selection in local coordinates. It is absolute with respect to the fractal's offscreen data.
Only the left and right parameters of the rectangle are valid for the Help Window. These specify the beginning and ending character positions of the selection.
If nothing is selected, an empty rectangle is returned.

Returns Rectangle
Examples CFG.getWindowRect()
» { 187, 190, 292, 450 }
Notes The target window can be any type.
For non-fractal windows, this simply returns the window boundaries in global coordinates.

The fractal information was saved to the target's previous save file.
Notes The target window must be a fractal window.
If the path is specified, CFG.saveAs functions as the "Save As" command. If no path is specified, this verb functions as the "Save" command.
If no path is specified and no file is associated with the fractal, false is returned (and an error is flagged).
See Also CFG.revertFractal
Verb CFG.savePalette
Syntax CFG.savePalette( path )
Parameters path is the file name and location to save the palette.
Action Saves the target's current palette to a file.
Returns True on success, false on failure.
Examples CFG.savePaletteFile( "HD:myPalette" )
» true
Notes The current palette may not be the target's custom palette.
See Also CFG.listPalettes
CFG.loadPalette
CFG.setPalFromList
Verb CFG.savePicture
Syntax CFG.savePICT( path, picType )
Parameters path is the file name and location to save the fractal's image.
picType is the graphic file format. Currently, only 'PICT' is supported.
Action Saves the fractal to a graphics file. Optionally, one may save only the selected region.
A selected area is saved only if part of the image is selected and the "save selection" preferences flag is set.
Future versions of CFG may support more graphics formats.
This function only works on registered versions of CFG.

CFG.putPICT
Verb CFG.scrollWindow
Syntax CFG.scrollWindow( dir, count )
Parameters dir is the direction to scroll the window.
count is the amount to move it.
Action Scrolls the target in the direction and amount specified.
Returns True on a successful scroll, false on scroll failure.
Examples CFG.scrollWindow( pageDown, 1 )
» true
Moves the target window down by 1 page.
Notes The New Parameters Window cannot be scrolled at all and the Help Window may only be scrolled vertically. If attempts are made to scroll in illegal directions, false will be returned.
The numeric definitions for direction are located in the "CFG Scripting Guide". You may also use the directions defined by Frontier.
If false is returned, it means that the scrolling has reached its limit in the specified direction.
See Also None
Verb CFG.selectAll
Syntax CFG.selectAll()
Parameters None
Action Selects the entire contents of the target.
Returns True if successful, false if selection could not be made.
Examples CFG.selectAll()
» true
Notes The target window cannot be the New Parameters Window as nothing can be selected in this type of window.
If the target is a fractal window, the entire fractal picture is selected. For Help Windows, all text for the current help section is selected.
This command cannot be used when the target window is building a fractal.
See Also CFG.deselect
CFG.getSelection
CFG.haveSelection
CFG.selectRectAbs
CFG.selectRectRel
Verb CFG.selectHelpItem
Syntax CFG.selectHelpItem( itemName )
Parameters itemName is the name of the item for which to obtain help information.
Action Display help information for a given item.
Returns True if item displayed, false on error.
Examples CFG.selectHelpItem( "Registration" )
» true
Notes The target must be the help window.
A list of valid help items is returned by CFG.listHelpItems().
See Also CFG.listHelpItems
CFG.openHelpWindow
Verb CFG.selectParamsWindow
Syntax CFG.selectParamsWindow()
Parameters None
Action Bring the New Parameters Window to the front.
Returns String with the name of the New Parameters Window or an empty string on an error.
Examples CFG.selectParamsWindow()
» "New Parameters"
Notes The New Parameters Window is made the target.
As the New Parameters Window cannot be disposed, it should always be present. It may not always be named "New Parameters", however.
See Also CFG.nthWindow
CFG.selectWindow
Verb CFG.selectRecAbs
Syntax CFG.selectRectAbs( rect )
Parameters rect is the coordinates of the selection
Action Select a region of the target using coordinates that references the top,left of the target's data.
Returns True if no error, false on error.
Examples r = rectange.set( 0, 0, 640, 480 )
CFG.selectRecAbs( r )
» true
Notes This verb should not be applied to the New Parameters Window as it cannot have any selections.
For fractal windows, the selected rectangle will appear at the specified location with respect to the fractal's offscreen data.
Thus if the rectangle was { 10, 10, 30, 30 }, the selection would appear 10 pixels down and to the right of the offscreen's top left corner. The location on screen depends on the current scroll coordinates.
For Help Windows, only the left and right fields of the rectangle are valid. These specify the character positions to start and end the selection respectively.
Relative and absolute have no meaning for the Help Window. Therefore, this function is the same as CFG.selectRectRel for the Help Window.
This command cannot be used when the target window is building a fractal.
See Also CFG.deselect
CFG.getSelection
CFG.haveSelection
CFG.selectAll
CFG.selectRectRel
Verb CFG.selectRectRel
Syntax CFG.selectRectRel( rect )
Parameters rect is the coordinates of the selection
Action Select a region of the target relative to the current view region.
Returns True if no error, false on error.
Examples r = rectangle.set( 0, 0, 256, 256 )
CFG.selectRectRel( r )
» true
Notes This verb should not be applied to the New Parameters Window as it cannot have any selections.
For fractal windows, the selected rectangle will appear relative to the top-left corner of the viewing region.
Thus if the rectangle was { 10, 10, 30, 30 }, the selection would appear 10 pixels down and to the right of the window's top left corner, no matter where scroll coordinates are located.
For Help Windows, only the left and right fields of the rectangle are valid.
These specify the character positions to start and end the selection respectively. Relative and absolute have no meaning for the Help Window. Therefore, this function is the same as CFG.selectRectAbs for the Help Window.
This command cannot be used when the target window is building a fractal.
See Also CFG.deselect
CFG.getSelection
CFG.haveSelection
CFG.selectAll
CFG.selectRectAbs
Verb CFG.selectWindow
Syntax CFG.selectWindow( name )
Parameters name is the title of the window to select.
Action Makes the specified window the front-most window.
Returns True if the named window was found or false if no such window exists.
Examples CFG.selectWindow( "Mandelbrot 1" )
» true
Notes The selected window becomes the target window.
See Also CFG.getTarget
CFG.nthWindow
CFG.selectParamsWindow
CFG.setTarget
Verb CFG.setDepth
Syntax CFG.setDepth( depth )
Parameters depth is the number of bits per pixel. Default values are defined in "CFG.const.depth...". A setting of CFG.const.depthDeep means to use the depth of the deepest screen.
Action Sets the target's color depth.
Returns True if depth altered, false on error.
Examples CFG.setDepth( CFG.const.depth16Bit )
» true
Notes Always reset the target window after false is returned. It is possible that a memory allocation error will occur when attempting to change the depth of the offscreen buffer. In this case, the window may be disposed.
If the target is not a fractal window, the new depth will become the default depth for new fractals. This information will be reflected in the New Parameters Window.
The depth is actually a field of the preferences. However, since it is unwieldy to handle the preferences structure just to modify the fractal color depth, this function and CFG.getDepth were created.
This command cannot be used when the target window is building a fractal.
See Also CFG.getDepth
CFG.getPreferences
CFG.setPreferences
Verb CFG.setFractalData
Syntax CFG.setFractalData( fracData )
Parameters fracData is a record containing the data fields that the user wants to modify.
Action Inserts the fractal data into the target.
Returns True if the data was applied, false if the data was invalid data or if not a fractal window.
The meaning of this data depends on the type of fractal that it came from (which is determined from CFG.getFractalType). The record structure is located in the "CFG Scripting Guide."
Fields that the user does not wish to alter can be omitted.
Data verification will be performed.
This command cannot be used when the target window is building a fractal.
See Also CFG.getBinary
Verb CFG.setFractalType
Syntax CFG.setFractalType( fractal )
Parameters fractal is the name or ID of a fractal type. Constants are defined in "CFG.const.ftype..." and "CFG.const.fname...".
Action Sets the fractal type to use for new fractals.
Returns True if desired fractal could be set, false otherwise.
Notes The target cannot be a fractal window, as once a fractal is assigned to a window, it cannot be changed.
See Also CFG.getFractalType
CFG.listFractalTypes
Verb CFG.setFSizeCustom
Syntax CFG.setFSizeCustom( customSize )
Parameters customSize is a Point whose horizontal and vertical fields specify the width and height of the fractal respectively.
Action Sets the fractal size according to the user specified horizontal and vertical coordinates.
Returns True if size was valid or false on error.
Examples p = point( 640 + 480 * 0x10000 ) « a little trick to use h,v integers to create a point
CFG.setFSizeCustom( p )
» true
p = point( "-10, 32001" )
CFG.setFSizeCustom( p )
» false
Both the fields of customSize are invalid.
Notes If the target window is not a fractal, the global size values are modified, which specify the size of newly created fractals. This information will be reflected in the New Parameters Window.
This command cannot be used when the target window is building a fractal.
See Also CFG.setFSizeMenu
Verb CFG.setFSizeMenu
Syntax CFG.setFSizeMenu( sizeItem )
Parameters sizeItem is a constant that defines which standard size to use. See "CFG.const.fsize..." for a list of default sizes.
Action Set the fractal's size to standard sizes displayed in the Size Menu.
Returns True if the fractal size was changed, false on error.
Sets the fractal size to that of a 13" monitor (640 x 480 pixels).
CFG.setFSizeMenu( 9 )
» false
Size item number is invalid.
Notes If the target window is not a fractal, the global size values are modified, which specify the size of newly created fractals. This information will be reflected in the New Parameters Window.
Use the CFG.setFSizeCustom command for non-standard image sizes.
This command cannot be used when the target window is building a fractal.
See Also CFG.setFSizeCustom
Verb CFG.setLimitExtreme
Syntax CFG.setLimitExtreme( limit )
Parameters limit is a Boolean set to true to turn the limiting on and false to turn it off.
Action Alter the target's limit extreme value.
Returns True
Examples CFG.setLimitExtreme( true )
» true
Notes The target may be any type of window.
If the target is the Help Window or New Parameters window, the setting is applied to the global setting, which affects newly created fractals.
See Also CFG.getLimitExtreme
Verb CFG.setPalFromList
Syntax CFG.setPalFromList( paletteTitle )
Parameters paletteTitle is the name of the palette that appears in the target's Palette menu.
Action Sets the palette entitled paletteTitle as the target's current palette.
The palette entitled "An ugly palette" does not exist in the target's Palette menu.
Notes If the target is a fractal window, the palette is made the current palette. Colors are altered immediately for 4 and 8 bit systems. Fractals with more colors require a redraw.
If the target is not a fractal window, the new palette will be the default palette for new fractals. This information is displayed in the New Parameters Window.
The palette menu has a set of standard palette defined and one custom palette per fractal. If you wish to assign the custom palette, be sure to obtain its name by using CFG.getPaletteList().
Note that the custom palette displayed in the Palette menu is for the top fractal window only. If the target is not the top-most window, the custom palette in the Palette menu may not be the target's custom palette.
This command cannot be used when the target window is building a fractal.
See Also CFG.getPaletteFile
CFG.listPalettes
CFG.savePaletteFile
Verb CFG.setPreferences
Syntax CFG.setPreferences( prefs )
Parameters prefs is a record with the preferences data.
Action Copies the data into the target's preferences.
Notes Setting to foreground mode will prevent CFG from processing further Apple Events while a fractal is generating.
See Also CFG.getSpeed
Verb CFG.setTarget
Syntax CFG.setTarget( name )
Parameters name is the title of the window which will be made the target. If name is an empty string, the front-most window is made target.
Action Makes the specified window the target window.
Returns A string with the title of the target window, or an empty string if the desired target was not found.
Examples CFG.setTarget( "Mandelbrot 1" )
» "Mandelbrot 1"
CFG.setTarget( "" )
» "Dragon 2"
The front-most window is made the target since the name parameter was an empty string. "Dragon 2" is the name of the new target window.
Notes If an empty string is passed as the desired target's title, the front-most window is set as the target and its name is returned.
If the specified target was not found, an empty string is returned. In this case, the target of subsequent operations will default to the front-most window.
See Also CFG.getTarget
CFG.selectWindow
Verb CFG.windowType
Syntax CFG.windowType()
Parameters None
Action Get the window type of the target.
Returns An integer containing the window type. Window type constants are defined in CFG.const.wtype...".
Examples CFG.windowType()
» 1
Notes The target may be any type of window.
The Custom Fractal Window and Fractal Movie Window are not supported in the current version of CFG, but may be in future versions.
See Also CFG.getFractalType
Verb CFG.zoomInOut
Syntax CFG.zoomInOut( zIn )
Parameters zIn is a Boolean specifying whether to zoom in or out. See "CFG.const.zoom...".
Action Zooms the target in or out by a factor of two.
Returns True if zoom was OK, false on error (such as target not a fractal).
Examples CFG.zoomInOut( CFG.const.zoomIn )
» true
Zooming in on the fractal (by a scale factor of 2).
CFG.zoomInOut( CFG.const.zoomOut )
» true
Zooming out on the fractal.
Notes The target must be a fractal, but it cannot be a Random Walk fractal.
This command cannot be used when the target window is building a fractal.
See Also CFG.zoomSelection
CFG.zoomValue
Verb CFG.zoomSelection
Syntax CFG.zoomSelection()
Parameters None
Action Zooms in on the fractal, fitting the selected area to the fractal size.
Returns True on success, false on failure.
Examples CFG.zoomSelection()
» true
Notes The target window must be a fractal, but it cannot be a Random Walk fractal.
The fractal must have a selection. The selection becomes the fractal's bounding rectangle. Thus, the top of the selection will become the new top of the fractal, the selection's left side will become the fractal's left edge, etc.
This command cannot be used when the target window is building a fractal.
See Also CFG.zoomInOut
CFG.zoomValue
Verb CFG.zoomValue
Syntax CFG.zoomValue( zoomX, zoomY )
Parameters zoomX and zoomY are floating point numbers (double precision) which specify the amount to zoom the fractal (horizontally and vertically)
Action Zoom in on the fractal by the specified amount.
Returns True if successful, false on error.
Examples CFG.zoom( 3.0 )
» true
Zooms in on fractal by a factor of 3x.
CFG.zoom( 0.5 )
» true
Zooms out by a factor of 2 (1 / 0.5).
Notes The target window must be a fractal, but it cannot be a Random Walk fractal.
One zooms in by specifying a value greater than one, while one zooms out with values between zero and one.
That is, one may zoom out by a factor X by specifying the zoom amount to be (1 / X).
Zoom values less or equal to 0 are invalid.
This command cannot be used when the target window is building a fractal.
See Also CFG.zoomInOut
CFG.zoomSelection
