| 159 | or uses the screen. The strings can be clipped or wrapped.\r |
| 160 | Optionally, the function also returns the information about each\r |
| 161 | row and the character position on that row. If\r |
| 162 | EFI_HII_OUT_FLAG_CLIP is set, then text will be formatted only\r |
| 163 | based on explicit line breaks and all pixels which would lie\r |
| 164 | outside the bounding box specified by Width and Height are\r |
| 165 | ignored. The information in the RowInfoArray only describes\r |
| 166 | characters which are at least partially displayed. For the final\r |
| 167 | row, the LineHeight and BaseLine may describe pixels which are\r |
| 168 | outside the limit specified by Height (unless\r |
| 169 | EFI_HII_OUT_FLAG_CLIP_CLEAN_Y is specified) even though those\r |
| 170 | pixels were not drawn. The LineWidth may describe pixels which\r |
| 171 | are outside the limit specified by Width (unless\r |
| 172 | EFI_HII_OUT_FLAG_CLIP_CLEAN_X is specified) even though those\r |
| 173 | pixels were not drawn. If EFI_HII_OUT_FLAG_CLIP_CLEAN_X is set,\r |

| 175 | if a character????s right-most on pixel cannot fit, then it will\r |
| 176 | not be drawn at all. This flag requires that\r |
| 177 | EFI_HII_OUT_FLAG_CLIP be set. If EFI_HII_OUT_FLAG_CLIP_CLEAN_Y\r |
| 178 | is set, then it modifies the behavior of EFI_HII_OUT_FLAG_CLIP\r |
| 179 | so that if a row????s bottom-most pixel cannot fit, then it will\r |
| 180 | not be drawn at all. This flag requires that\r |
| 181 | EFI_HII_OUT_FLAG_CLIP be set. If EFI_HII_OUT_FLAG_WRAP is set,\r |
| 182 | then text will be wrapped at the right-most line-break\r |
| 183 | opportunity prior to a character whose right-most extent would\r |
| 184 | exceed Width. If no line-break opportunity can be found, then\r |
| 185 | the text will behave as if EFI_HII_OUT_FLAG_CLIP_CLEAN_X is set.\r |
| 186 | This flag cannot be used with EFI_HII_OUT_FLAG_CLIP_CLEAN_X. If\r |
| 187 | EFI_HII_OUT_FLAG_TRANSPARENT is set, then BackgroundColor is\r |
| 188 | ignored and all ????off???? pixels in the character????s drawn\r |
| 189 | will use the pixel value from Blt. This flag cannot be used if\r |
| 190 | Blt is NULL upon entry. If EFI_HII_IGNORE_IF_NO_GLYPH is set,\r |
| 191 | then characters which have no glyphs are not drawn. Otherwise,\r |
| 192 | they are replaced with Unicode character 0xFFFD (REPLACEMENT\r |
| 193 | CHARACTER). If EFI_HII_IGNORE_LINE_BREAK is set, then explicit\r |
| 194 | line break characters will be ignored. If\r |
| 195 | EFI_HII_DIRECT_TO_SCREEN is set, then the string will be written\r |
| 196 | directly to the output device specified by Screen. Otherwise the\r |
| 197 | string will be rendered to the bitmap specified by Bitmap.\r |
