1507 @param This A pointer to the EFI_HII_FONT_PROTOCOL instance.
1508 @param Flags Describes how the string is to be drawn.
1509 @param String Points to the null-terminated string to be
1510 displayed.
1511 @param StringInfo Points to the string output information,
1512 including the color and font. If NULL, then the
1513 string will be output in the default system font
1514 and color.
1515 @param Blt If this points to a non-NULL on entry, this
1516 points to the image, which is Width pixels wide
1517 and Height pixels high. The string will be drawn
1518 onto this image and
1519 EFI_HII_OUT_FLAG_CLIP is implied. If this points
1520 to a NULL on entry, then a buffer
1521 will be allocated to hold the generated image and
1522 the pointer updated on exit. It is the caller's
1523 responsibility to free this buffer.
1524 @param BltX Specifies the offset from the left and top edge
1525 of the image of the first character cell in the
1526 image.
1527 @param BltY Specifies the offset from the left and top edge
1528 of the image of the first character cell in the
1529 image.
1530 @param RowInfoArray If this is non-NULL on entry, then on exit, this
1531 will point to an allocated buffer containing
1532 row information and RowInfoArraySize will be
1533 updated to contain the number of elements.
1534 This array describes the characters which were at
1535 least partially drawn and the heights of the
1536 rows. It is the caller's responsibility to free
1537 this buffer.
1538 @param RowInfoArraySize If this is non-NULL on entry, then on exit it
1539 contains the number of elements in RowInfoArray.
1540 @param ColumnInfoArray If this is non-NULL, then on return it will be
1541 filled with the horizontal offset for each
1542 character in the string on the row where it is
1543 displayed. Non-printing characters will have
1544 the offset ~0. The caller is responsible to
1545 allocate a buffer large enough so that there
1546 is one entry for each character in the string,
1547 not including the null-terminator. It is possible
1548 when character display is normalized that some
1549 character cells overlap.

2232 @param Flags Describes how the string is to be drawn.
2233 @param PackageList The package list in the HII database to search
2234 for the specified string.
2235 @param StringId The string's id, which is unique within
2236 PackageList.
2237 @param Language Points to the language for the retrieved string.
2238 If NULL, then the current system language is
2239 used.
2240 @param StringInfo Points to the string output information,
2241 including the color and font. If NULL, then the
2242 string will be output in the default system font
2243 and color.
2244 @param Blt If this points to a non-NULL on entry, this
2245 points to the image, which is Width pixels wide
2246 and Height pixels high. The string will be drawn
2247 onto this image and
2248 EFI_HII_OUT_FLAG_CLIP is implied. If this points
2249 to a NULL on entry, then a buffer
2250 will be allocated to hold the generated image and
2251 the pointer updated on exit. It is the caller's
2252 responsibility to free this buffer.
2253 @param BltX Specifies the offset from the left and top edge
2254 of the image of the first character cell in the
2255 image.
2256 @param BltY Specifies the offset from the left and top edge
2257 of the image of the first character cell in the
2258 image.
2259 @param RowInfoArray If this is non-NULL on entry, then on exit, this
2260 will point to an allocated buffer containing
2261 row information and RowInfoArraySize will be
2262 updated to contain the number of elements.
2263 This array describes the characters which were at
2264 least partially drawn and the heights of the
2265 rows. It is the caller's responsibility to free
2266 this buffer.
2267 @param RowInfoArraySize If this is non-NULL on entry, then on exit it
2268 contains the number of elements in RowInfoArray.
2269 @param ColumnInfoArray If this is non-NULL, then on return it will be
2270 filled with the horizontal offset for each
2271 character in the string on the row where it is
2272 displayed. Non-printing characters will have
2273 the offset ~0. The caller is responsible to
2274 allocate a buffer large enough so that there
2275 is one entry for each character in the string,
2276 not including the null-terminator. It is possible
2277 when character display is normalized that some
2278 character cells overlap.
