| |
| Additional fix for Savannah bug #30306. |
| |
| * src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the |
| POST fragment is 0, the segment is completely ignored. The declared |
| length of the segment is not cared at all. According to Adobe |
| Technical Note 5040, type 0 segment is a comment only and should not |
| be loaded for the interpreter. Reported by Robert Święcki. |

| int' to avoid integer overflow. |
| |

| threshold values for `width' and `height'. This is not directly |
| related to the bug fix but makes sense anyway. |
| |
| 2010-07-01 suzuki toshiya <mpsuzuki@hiroshima-u.ac.jp> |
| |
| Initial fix for Savannah bug #30306. |
| |
| * src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the |

| Fix Savannah bug #29846. |
| |
| Previously we discovered fonts which used `setcurrentpoint' to set |
| the initial point of a contour to 0,0. This caused FreeType to |
| raise an error, because the `setcurrentpoint' operator is only |
| supposed to be used with the results from an OtherSubr subroutine. |
| |
| This was fixed by simply ignoring the error and carrying on. |
| |
| Now we have found a font which uses setcurrentpoint to actually |
| establish a non-zero point for a contour during the course of a |
| glyph program. FWIW, these files may be produced by an application |
| called `Intaglio' on the Mac, when converting TrueType fonts to |
| Type 1. |
| |
| The fix allows the new invalid behaviour, the old invalid behaviour |
| and real proper usage of the operator to work the same way as Adobe |
| interpreters apparently do. |
| |
| (t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top |
| two elements of the stack to establish unconditionally the current x |
| and y coordinates. |
| |
| Make the `flex' subroutine handling (OtherSubr 0) put the current |
| x,y coordinates onto the stack, instead of two dummy uninitialised |
| values. |
