im_puts_dbyte
Purpose This function places the indicated glyphs in the current DBFS font on the
screen.
Syntax #include "imt209x.h"
IM_STATUS im_puts_dbyte
(IM_USHORT *
dbfschar,
IM_ATTRIBUTES attrib);
IN Parameters
dbfschar Pointer to a series of indices for glyphs in the fontfile (in glyphs).
Values of offset will plot the bitmap starting at 0 in the file. The series is
terminated by 0x0000.
attrib Specifies the display attribute for the glyphs. Choose one or more of
these constants:
IM_NORMAL Set bits in the bitmap are set on the screen.
IM_INVERSE Cleared bits in the bitmap are set on the screen. Mutually
exclusive with IM_NORMAL.
IM_UNDERLINE The last row of pixels in the character cell are plotted
as though they were set in the bitmap.
IM_NOT_ADVANCING_CURSOR The cursor is not advanced after the
glyph is plotted. This is useful in preventing scrolling when plotting a
glyph in the last position of the last row, but causes successive characters
in a string to be plotted in the same position.
OUT Parameters None.
Return Value This function returns one of these codes:
IM_SUCCESS Success.
IM_INVALID_PARAM_1 Either the glyph could not be mapped or the
attribute requested is invalid.
IM_INVALID_FUNCTION
im_dbyte_setfont()
must be called
first.
Notes The string must be terminated by a double byte null (i.e., two bytes of 0).
