GpiSetCharMode (1.2)
Function Group  Overview                          Up Next Previous
────────────────────────────────────────────────────────────────────────────
 
#define INCL_GPIPRIMITIVES
 
BOOL GpiSetCharMode(hps, flMode)
HPS hps;        /* presentation-space handle */
LONG flMode;    /* character mode            */
 
The GpiSetCharMode function sets the character mode. The character mode
specifies which character attributes to use when drawing characters.
 
If the attribute mode is AM_PRESERVE, the function saves the previous
character mode on the attribute stack when it sets the new mode. The
previous character mode can be retrieved by using the GpiPop function.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
hps        Identifies the presentation space.
 
flMode     Specifies the character mode. It can be one of the following
           values:
 
           Value       Meaning
           ─────────────────────────────────────────────────────────────────
           CM_DEFAULT  Use the default.
 
           CM_MODE1    Use an image font, as determined by the character-set
                       attribute. The positioning of characters is
                       influenced only by the character-direction attribute;
                       other character attributes are ignored.
 
           CM_MODE2    Use an image font, as determined by the character-set
                       attribute. The character box, character angle,
                       character direction, character shear, character
                       spacing, character extra, and character break extra
                       values are taken into consideration for positioning
                       successive characters. Individual character
                       definitions are not scaled or rotated.
 
           CM_MODE3    Use a vector font, as determined by the character-set
                       attribute. All character attributes are followed
                       exactly for positioning individual characters,
                       scaling, rotating, and shearing.
 
           If the specified mode is not valid, the default is used.
 
Return Value
 
The return value is GPI_OK if the function is successful or GPI_ERROR if an
error occurred.
 
Errors
 
Use the WinGetLastError function to retrieve the error value, which may be
one of the following:
 
     PMERR_INV_CHAR_MODE_ATTR
     PMERR_INV_HPS
     PMERR_PS_BUSY
