In the following routines, ovalWidth and ovalHeight specify the diameters of curvature for the corners.

__________________________________________
PaintRoundRect *399*
Input names: r, ovalWidth, ovalHeight
Input types: Rect, integer, integer
Description: Paints the specified rounded-corner rectangle with the current grafPort’s pen pattern and mode.
__________________________________________
EraseRoundRect *399*
Input names: r, ovalWidth, ovalHeight
Input types: Rect, integer, integer
Description: Paints the specified rounded-corner rectangle with the current grafPort’s background pattern bkPat.
__________________________________________
InvertRoundRect *399*
Input names: r, ovalWidth, ovalHeight
Input types: Rect, integer, integer
Description: Inverts the pixels enclosed by the specified rounded-corner rectangle: every white pixel becomes black and every black pixel becomes white.
__________________________________________
FillRoundRect *399*
Input names: r, ovalWidth, ovalHeight, pat
Input types: Rect, integer, integer, Pattern
Description: Fills the specified rounded-corner rectangle with the given pattern.

Arcs and Wedges
In the following routines, startAngle indicates where the arc begins and is treated MOD 360. ArcAngle defines the extent of the arc.

FrameArc *400*
Input names: aRect, startAngle, arcAngle
Input types: Rect, integer, integer
Description: Draws an arc of the oval that fits inside the specified rectangle using the current grafPort’s pen pattern, mode, and size.
__________________________________________
PaintArc *400*
Input names: r, startAngle, arcAngle
Input types: Rect, integer, integer
Description: Paints a wedge of the oval just inside the specified rectangle with the current grafPort’s pen pattern and mode.
 
__________________________________________
EraseArc *400*
Input names: r, startAngle, arcAngle
Input types: Rect, integer, integer
Description: Paints a wedge of the oval just inside the specified rectangle with the current grafPort’s background pattern bkPat.
__________________________________________
InvertArc *400*
Input names: r, startAngle, arcAngle
Input types: Rect, integer, integer
Description: Inverts the pixels enclosed by a wedge of the oval just inside the specified rectangle: every white pixel becomes black and every black pixel becomes white.
__________________________________________
FillArc *401*
Input names: r, startAngle, arcAngle, pat
Input types: Rect, integer, integer, Pattern
Description: Fills a wedge of the oval just inside the specified rectangle with the given pattern.

Bit Transfer
__________________________________________
ScrollRect *401*
Input names: r, dh, dv, updateRgn
Input types: Rect, integer, integer, RgnHandle
Description: Shifts the bits that are inside the intersection of the specified rectangle. The bits are shifted a distance of dh horizontally and dv vertically. The bits that are shifted out of the scroll area are lost, they are neither placed outside the area nor saved. The space created by the scroll is filled with the grafPort’s background pattern and the updateRgn is changed to this filled area. ScrollRect doesn’t change the coordinate system of the grafPort, it simply moves the entire document to different coordinates.
Description: CopyBits transfers a bit image between any two bit maps or pixel maps and clips the result to the area specified by the maskRgn parameter. The transfer may be performed in any of the eight source transfer modes. The source rectangle is completely aligned with the destination rectangle; if the rectangles are of different sizes, the bit image is expanded or shrunk as necessary to fit the destination rectangle.
You can use the following constants to specify the source transfer mode. (For more information, see Inside Macintosh.)

OpenPicture *402*
Input names: picFrame
Input types: Rect
Output names: PicHandle
Output types: PicHandle
Description: Returns a handle to a new picture that has the given rectangle as its picture frame, and tells QuickDraw to start saving as the picture definition all calls to drawing routines and all picture comments (if any).
__________________________________________
ClosePicture *402*
Description: Tells QuickDraw to stop saving routine calls and picture comments as the definition of the currently open picture. Only one ClosePicture should be performed for every OpenPicture.
__________________________________________
PicComment *403*
Input names: kind, dataSize, dataHandle
Input types: integer, integer, Handle
Description: Inserts the specified comment into the definition of the currently open picture. DataHandle is a handle to additional data if desired, and dataSize is the size of that data in bytes. The kind parameter identifies the type of comment.
You can use the following constants to specify the kind parameter. (For more information, see Inside Macintosh.)
constant value
picLParen 0
picRParen 1
__________________________________________
DrawPicture *403*
Input names: myPicture, dstRect
Input types: PicHandle, Rect
Description: Takes the part of the given picture that’s inside the picture frame and draws it in dstRect, expanding or shrinking it as necessary to align the borders of the picture frame with dstRect.
__________________________________________
KillPicture *403*
Input names: myPicture
Input types: PicHandle
Description: Releases the memory occupied by the given picture.
__________________________________________
GetPicture *404*
Input names: picID
Input types: integer
Output names: PicHandle
Output types: PicHandle
Description: Returns a handle to the picture having the given resource ID, reading it from the resource file, if necessary. If the resource can’t be read, GetPicture returns NIL.
