Data Structures

The Scrap Style Table

The style scrap record contains the scrap style table. Unlike the main style table for an edit record, the scrap style table may contain duplicate elements; the entries in the table correspond one-to-one with the style runs in the text. The scrpStartChar field of each entry gives the starting position for the run.

The scrpStyleTab data type defines the scrap style table data structure, which is an array of scrap style element records. The ScrpSTElement data type defines each scrap style element record.

TYPE  ScrpSTElement = 
      RECORD
         scrpStartChar: LongInt;    {offset to start of style}
         scrpHeight:    Integer;    {line height}
         scrpAscent:    Integer;    {font ascent}
         scrpFont:      Integer;    {font family ID }
         scrpFace:      Style;      {character style}
         scrpSize:      Integer;    {size in points}
         scrpColor:     RGBColor;   {absolute (RGB) color}
      END;

ScrpSTTable = ARRAY[0..1600] OF ScrpSTElement;
