2339 | @param This A pointer to the EFI_HII_FONT_PROTOCOL instance.\r | |
2340 | @param Flags Describes how the string is to be drawn.\r | |
2341 | @param PackageList The package list in the HII database to search\r | |
2342 | for the specified string.\r | |
ac644614 | 2343 | @param StringId The string's id, which is unique within\r |
93e3992d | 2344 | PackageList.\r |
2345 | @param Language Points to the language for the retrieved string.\r | |
2346 | If NULL, then the current system language is\r | |
2347 | used.\r | |
2348 | @param StringInfo Points to the string output information,\r | |
2349 | including the color and font. If NULL, then the\r | |
2350 | string will be output in the default system font\r | |
2351 | and color.\r | |
2352 | @param Blt If this points to a non-NULL on entry, this\r | |
2353 | points to the image, which is Width pixels wide\r | |
2354 | and Height pixels high. The string will be drawn\r | |
2355 | onto this image and\r | |
2356 | EFI_HII_OUT_FLAG_CLIP is implied. If this points\r | |
2357 | to a NULL on entry, then a buffer\r | |
2358 | will be allocated to hold the generated image and\r | |
ac644614 | 2359 | the pointer updated on exit. It is the caller's\r |
93e3992d | 2360 | responsibility to free this buffer.\r |
e90b081a | 2361 | @param BltX Specifies the offset from the left and top edge\r |
2362 | of the image of the first character cell in the\r | |
2363 | image.\r | |
2364 | @param BltY Specifies the offset from the left and top edge\r | |
93e3992d | 2365 | of the image of the first character cell in the\r |
2366 | image.\r | |
2367 | @param RowInfoArray If this is non-NULL on entry, then on exit, this\r | |

2369 | row information and RowInfoArraySize will be\r | |
2370 | updated to contain the number of elements.\r | |
2371 | This array describes the characters which were at\r | |
2372 | least partially drawn and the heights of the\r | |
ac644614 | 2373 | rows. It is the caller's responsibility to free\r |
93e3992d | 2374 | this buffer.\r |
2375 | @param RowInfoArraySize If this is non-NULL on entry, then on exit it\r | |
2376 | contains the number of elements in RowInfoArray.\r | |
2377 | @param ColumnInfoArray If this is non-NULL, then on return it will be\r | |
2378 | filled with the horizontal offset for each\r | |
2379 | character in the string on the row where it is\r | |
2380 | displayed. Non-printing characters will have\r | |
2381 | the offset ~0. The caller is responsible to\r | |
2382 | allocate a buffer large enough so that there\r | |
2383 | is one entry for each character in the string,\r | |
2384 | not including the null-terminator. It is possible\r | |
