1503 @param This A pointer to the EFI_HII_FONT_PROTOCOL instance.
1504 @param Flags Describes how the string is to be drawn.
1505 @param String Points to the null-terminated string to be
1506 displayed.
1507 @param StringInfo Points to the string output information,
1508 including the color and font. If NULL, then the
1509 string will be output in the default system font
1510 and color.
1511 @param Blt If this points to a non-NULL on entry, this
1512 points to the image, which is Width pixels wide
1513 and Height pixels high. The string will be drawn
1514 onto this image and
1515 EFI_HII_OUT_FLAG_CLIP is implied. If this points
1516 to a NULL on entry, then a buffer
1517 will be allocated to hold the generated image and
1518 the pointer updated on exit. It is the caller's
1519 responsibility to free this buffer.
1520 @param BltX Specifies the offset from the left and top edge
1521 of the image of the first character cell in the
1522 image.
1523 @param BltY Specifies the offset from the left and top edge
1524 of the image of the first character cell in the
1525 image.
1526 @param RowInfoArray If this is non-NULL on entry, then on exit, this
1527 will point to an allocated buffer containing
1528 row information and RowInfoArraySize will be
1529 updated to contain the number of elements.
1530 This array describes the characters which were at
1531 least partially drawn and the heights of the
1532 rows. It is the caller's responsibility to free
1533 this buffer.
1534 @param RowInfoArraySize If this is non-NULL on entry, then on exit it
1535 contains the number of elements in RowInfoArray.
1536 @param ColumnInfoArray If this is non-NULL, then on return it will be
1537 filled with the horizontal offset for each
1538 character in the string on the row where it is
1539 displayed. Non-printing characters will have
1540 the offset ~0. The caller is responsible to
1541 allocate a buffer large enough so that there
1542 is one entry for each character in the string,
1543 not including the null-terminator. It is possible
1544 when character display is normalized that some
1545 character cells overlap.

2227 @param Flags Describes how the string is to be drawn.
2228 @param PackageList The package list in the HII database to search
2229 for the specified string.
2230 @param StringId The string's id, which is unique within
2231 PackageList.
2232 @param Language Points to the language for the retrieved string.
2233 If NULL, then the current system language is
2234 used.
2235 @param StringInfo Points to the string output information,
2236 including the color and font. If NULL, then the
2237 string will be output in the default system font
2238 and color.
2239 @param Blt If this points to a non-NULL on entry, this
2240 points to the image, which is Width pixels wide
2241 and Height pixels high. The string will be drawn
2242 onto this image and
2243 EFI_HII_OUT_FLAG_CLIP is implied. If this points
2244 to a NULL on entry, then a buffer
2245 will be allocated to hold the generated image and
2246 the pointer updated on exit. It is the caller's
2247 responsibility to free this buffer.
2248 @param BltX Specifies the offset from the left and top edge
2249 of the image of the first character cell in the
2250 image.
2251 @param BltY Specifies the offset from the left and top edge
2252 of the image of the first character cell in the
2253 image.

2255 will point to an allocated buffer containing
2256 row information and RowInfoArraySize will be
2257 updated to contain the number of elements.
2258 This array describes the characters which were at
2259 least partially drawn and the heights of the
2260 rows. It is the caller's responsibility to free
2261 this buffer.
2262 @param RowInfoArraySize If this is non-NULL on entry, then on exit it
2263 contains the number of elements in RowInfoArray.
2264 @param ColumnInfoArray If this is non-NULL, then on return it will be
2265 filled with the horizontal offset for each
2266 character in the string on the row where it is
2267 displayed. Non-printing characters will have
2268 the offset ~0. The caller is responsible to
2269 allocate a buffer large enough so that there
2270 is one entry for each character in the string,
2271 not including the null-terminator. It is possible
2272 when character display is normalized that some
2273 character cells overlap.
