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'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'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.

Flags - Describes how the string is to be drawn.
|
|
PackageList - The package list in the HII database to search for the specified string.

|
StringId - The string'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.

This - A pointer to the EFI_HII_FONT_PROTOCOL instance.

Char - Character to retrieve.

StringInfo - Points to the string font and color information or NULL if the string should use the

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'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.
