GetCharWidthFloat
The GetCharWidthFloat
function retrieves the fractional widths of consecutive characters in a
specified range from the current font.
BOOL GetCharWidthFloat(
|
HDC hdc, |
// handle of device
context |
|
UINT iFirstChar, |
// first-character
code point |
|
UINT iLastChar, |
// last-character
code point |
|
PFLOAT pxBuffer |
// address of
buffer that receives width-values |
|
); |
|
Parameters
hdc
Identifies
the device context.
iFirstChar
Specifies the
code point of the first character in the group of consecutive characters.
iLastChar
Specifies the
code point of the last character in the group of consecutive characters.
pxBuffer
Points to a
buffer to receive the character widths.
Return Values
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero. To get extended error information,
call GetLastError.
Remarks
The returned
widths are in the 32-bit IEEE floating-point format. (The widths are measured
along the base line of the characters.)
If the iFirstChar
parameter identifies the letter a and the iLastChar parameter
identifies the letter z, GetCharWidthFloat retrieves the widths
of all lowercase characters.
If a
character does not exist in the current font, it is assigned the width of the
default character.
