TextExtent -- Determine raster extent of text data. (V36)
TextExtent(rp, string, count, textExtent)
A1 A0 D0:16 A2
void textExtent(struct RastPort *, STRPTR, WORD,
struct TextExtent *);
This function determines a more complete metric of the space
that a text string would render into than the TextLength()
function.
rp - a pointer to the RastPort which describes where the
text attributes reside.
string - the address of the string to determine the length of.
count - the number of characters in the string.
If zero, there are no characters in the string.
textExtent - a structure to hold the result.
textExtent is filled in as follows:
te_Width - same as TextLength() result: the rp_cp_x
advance that rendering this text would cause.
te_Height - same as tf_YSize. The height of the
font.
te_Extent.MinX - the offset to the left side of the
rectangle this would render into. Often zero.
te_Extent.MinY - same as -tf_Baseline. The offset
from the baseline to the top of the rectangle
this would render into.
te_Extent.MaxX - the offset of the left side of the
rectangle this would render into. Often the
same as te_Width-1.
te_Extent.MaxY - same as tf_YSize-tf_Baseline-1.
The offset from the baseline to the bottom of
the rectangle this would render into.
