1517 Renders a string to a bitmap or to the display.
1518
1519 @param This A pointer to the EFI_HII_FONT_PROTOCOL instance.
1520 @param Flags Describes how the string is to be drawn.
1521 @param String Points to the null-terminated string to be
1522 displayed.
1523 @param StringInfo Points to the string output information,
1524 including the color and font. If NULL, then the
1525 string will be output in the default system font
1526 and color.
1527 @param Blt If this points to a non-NULL on entry, this
1528 points to the image, which is Width pixels wide
1529 and Height pixels high. The string will be drawn
1530 onto this image and
1531 EFI_HII_OUT_FLAG_CLIP is implied. If this points
1532 to a NULL on entry, then a buffer
1533 will be allocated to hold the generated image and
1534 the pointer updated on exit. It is the caller's
1535 responsibility to free this buffer.
1536 @param BltX Specifies the offset from the left and top edge
1537 of the image of the first character cell in the
1538 image.
1539 @param BltY Specifies the offset from the left and top edge
1540 of the image of the first character cell in the
1541 image.
1542 @param RowInfoArray If this is non-NULL on entry, then on exit, this
1543 will point to an allocated buffer containing
1544 row information and RowInfoArraySize will be
1545 updated to contain the number of elements.
1546 This array describes the characters which were at
1547 least partially drawn and the heights of the
1548 rows. It is the caller's responsibility to free
1549 this buffer.
1550 @param RowInfoArraySize If this is non-NULL on entry, then on exit it
1551 contains the number of elements in RowInfoArray.
1552 @param ColumnInfoArray If this is non-NULL, then on return it will be
1553 filled with the horizontal offset for each
1554 character in the string on the row where it is
1555 displayed. Non-printing characters will have
1556 the offset ~0. The caller is responsible to
1557 allocate a buffer large enough so that there
1558 is one entry for each character in the string,
1559 not including the null-terminator. It is possible
1560 when character display is normalized that some
1561 character cells overlap.
1562
1563 @retval EFI_SUCCESS The string was successfully rendered.
1564 @retval EFI_OUT_OF_RESOURCES Unable to allocate an output buffer for
1565 RowInfoArray or Blt.
1566 @retval EFI_INVALID_PARAMETER The String or Blt was NULL.

2246 Render a string to a bitmap or the screen containing the contents of the specified string.
2247
2248 @param This A pointer to the EFI_HII_FONT_PROTOCOL instance.
2249 @param Flags Describes how the string is to be drawn.
2250 @param PackageList The package list in the HII database to search
2251 for the specified string.
2252 @param StringId The string's id, which is unique within
2253 PackageList.
2254 @param Language Points to the language for the retrieved string.
2255 If NULL, then the current system language is
2256 used.
2257 @param StringInfo Points to the string output information,
2258 including the color and font. If NULL, then the
2259 string will be output in the default system font
2260 and color.
2261 @param Blt If this points to a non-NULL on entry, this
2262 points to the image, which is Width pixels wide
2263 and Height pixels high. The string will be drawn
2264 onto this image and
2265 EFI_HII_OUT_FLAG_CLIP is implied. If this points
2266 to a NULL on entry, then a buffer
2267 will be allocated to hold the generated image and
2268 the pointer updated on exit. It is the caller's
2269 responsibility to free this buffer.
2270 @param BltX Specifies the offset from the left and top edge
2271 of the image of the first character cell in the
2272 image.
2273 @param BltY Specifies the offset from the left and top edge
2274 of the image of the first character cell in the
2275 image.
2276 @param RowInfoArray If this is non-NULL on entry, then on exit, this
2277 will point to an allocated buffer containing
2278 row information and RowInfoArraySize will be
2279 updated to contain the number of elements.
2280 This array describes the characters which were at
2281 least partially drawn and the heights of the
2282 rows. It is the caller's responsibility to free
2283 this buffer.
2284 @param RowInfoArraySize If this is non-NULL on entry, then on exit it
2285 contains the number of elements in RowInfoArray.
2286 @param ColumnInfoArray If this is non-NULL, then on return it will be
2287 filled with the horizontal offset for each
2288 character in the string on the row where it is
2289 displayed. Non-printing characters will have
2290 the offset ~0. The caller is responsible to
2291 allocate a buffer large enough so that there
2292 is one entry for each character in the string,
2293 not including the null-terminator. It is possible
