3179 | Graphic Utility Library | Bug Report | Low | TIFFReadRGBAImageOriented Premultiplication rounding er... | New | Win32 | |
|
Task Description
TIFFReadRGBAImageOriented executes an alpha premultiplication even when the alpha value is stored as EXTRASAMPLE_UNASSALPHA. This leads to rounding errors.
example:
(correct mathematical rounding)
gt: 226 and alpha 0.5 -> 127
read the premultiplied value: 226*127/255 = 112.56 -> 113
converting to nonpremultiplied value: 113*255/127 = 226.89 -> 227
gt: 225 and alpha 0.5 -> 127
read the premultiplied value: 225*127/255 = 112.06 -> 112
converting to nonpremultiplied value: 112*255/127 = 224.88 -> 225
so we have a difference of 1 or 0 between the ground truth and the read value after undoing the premultiplication.
(incorrect mathematical rounding)
gt: 226 and alpha 0.5 -> 127
read the premultiplied value: 226*127/255 = 112.56 -> 112
converting to nonpremultiplied value: 112*255/127 = 224.88 -> 224
so incorrect mathematical rounding leading to much worse results.
Consider using a different way to read the tiff image (for instance ReadEncodedStrip). |

Brige |
Task Description
Depending in which walking are a character is, we draw the objects in a different order. This way we achieve the effect of forground and background.
each walking area holds a list that tells if an object in this scene is in front or behind the character.
we can locally change the order by introducing an additional walking area. |

Task Description
make string mutable. it's not worth the pain of having immutable/noncopyable strings. Especially without smart pointers. It would become easier but still you cannot write

3178 | Graphic Utility Library | Bug Report | Low | TIFF LZW/PackBits compression | Closed | All | |

Task Description
LZW and PackBits compressed images are not read correctly.
They differ slighty from the ground truth (provided in unsigned char in a header). note that the differ exactly in the same magnitude.
when i write the read image in PNG it look +/- right. so there must be some systematic error. I suspect it to be the TIFFReadRGBAImageOriented function |
