Routine Description:
|
||
Renders a string to a bitmap or to the display.
|
||
|
||
Arguments:
|
||
This - A pointer to the EFI_HII_FONT_PROTOCOL instance.
|
||
Flags - Describes how the string is to be drawn.
|
||
String - Points to the null-terminated string to be displayed.
|
||
StringInfo - Points to the string output information, including the color and font.
|
||
If NULL, then the string will be output in the default system font and color.
|
||
Blt - If this points to a non-NULL on entry, this points to the image, which is Width pixels
|
||
wide and Height pixels high. The string will be drawn onto this image and
|
||
EFI_HII_OUT_FLAG_CLIP is implied. If this points to a NULL on entry, then a
|
||
buffer will be allocated to hold the generated image and the pointer updated on exit. It
|
||
is the caller<65><72>s responsibility to free this buffer.
|
||
BltX,BLTY - Specifies the offset from the left and top edge of the image of the first character cell in
|
||
the image.
|
||
RowInfoArray - If this is non-NULL on entry, then on exit, this will point to an allocated buffer
|
||
containing row information and RowInfoArraySize will be updated to contain the
|
||
number of elements. This array describes the characters which were at least partially
|
||
drawn and the heights of the rows. It is the caller<65><72>s responsibility to free this buffer.
|
||
RowInfoArraySize - If this is non-NULL on entry, then on exit it contains the number of elements in
|
||
RowInfoArray.
|
||
ColumnInfoArray - If this is non-NULL, then on return it will be filled with the horizontal offset for each
|
||
character in the string on the row where it is displayed. Non-printing characters will
|
||
have the offset ~0. The caller is responsible to allocate a buffer large enough so that
|
||
there is one entry for each character in the string, not including the null-terminator. It
|
||
is possible when character display is normalized that some character cells overlap.
|
||
|
||
Returns:
|
||
EFI_SUCCESS - The string was successfully rendered.
|
||
EFI_OUT_OF_RESOURCES - Unable to allocate an output buffer for RowInfoArray or Blt.
|
||
EFI_INVALID_PARAMETER - The String was NULL.

Routine Description:

Arguments:

This - A pointer to the EFI_HII_FONT_PROTOCOL instance.
|

PackageList - The package list in the HII database to search for the specified string.
|

StringId - The string<6E><67>s id, which is unique within PackageList.
|
||
Language - Points to the language for the retrieved string. If NULL, then the current system
|
||
language is used.
|
||
StringInfo - Points to the string output information, including the color and font.
|
||
If NULL, then the string will be output in the default system font and color.
|
||
Blt - If this points to a non-NULL on entry, this points to the image, which is Width pixels

number of elements. This array describes the characters which were at least partially

drawn and the heights of the rows. It is the caller<65><72>s responsibility to free this buffer.

RowInfoArraySize - If this is non-NULL on entry, then on exit it contains the number of elements in

RowInfoArray.

Routine Description:

This function iterates through fonts which match the specified font, using

the specified criteria. If String is non-NULL, then all of the characters in

the string must exist in order for a candidate font to be returned.

Arguments:

This - A pointer to the EFI_HII_FONT_PROTOCOL instance.

FontHandle - On entry, points to the font handle returned by a

previous call to GetFontInfo() or NULL to start with the
|
||
first font. On return, points to the returned font handle or
|
||
points to NULL if there are no more matching fonts.
|
||
StringInfoIn - Upon entry, points to the font to return information about.
|
||
StringInfoOut - Upon return, contains the matching font<6E><74>s information.
|
||
If NULL, then no information is returned.
|
||
It's caller's responsibility to free this buffer.
|
||
String - Points to the string which will be tested to determine
|
||
if all characters are available. If NULL, then any font
|
||
is acceptable.
|
||
|
||
Returns:

EFI_SUCCESS - Matching font returned successfully.

EFI_NOT_FOUND - No matching font was found.
