StdText

The StdText procedure is QuickDraw's standard low-level routine for drawing text.

PROCEDURE StdText (byteCount:\xDDInteger; textBuf:\xDDPtr; 
                   numer,denom:\xDDPoint);

byteCount

The number of bytes of text to draw.

textBuf

A memory structure containing the text to draw.

numer

Scaling numerator.

denom

Scaling denominator.

DESCRIPTION

The StdText procedure draws text from the arbitrary structure in memory specified by the textBuf parameter, starting from the first byte and continuing for the number of bytes specified in the byteCount parameter. The numer and denom parameters specify the scaling factor: numer.v over denom.v gives the vertical scaling, and numer.h over denom.h gives the horizontal scaling factor.

SPECIAL CONSIDERATIONS

The StdText procedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.
