A career actor and independent software engineer, I am most active on Stackoverflow, Superuser, and Movies.
Currently between full-time software jobs, doing freelance. I'm always open to openings in the LA area (or elsewhere, with telecommute options). 10 years of experience.
Languages of highest proficiency (non-exhaustive):
- C/C++/x86-assembly
- PHP, Javascript
Experience in compiler development, OS kernel memory management, Web 2.0 applications, web crawlers, data mining, 3D raytracing, and data compression algorithm design.
A couple of my current projects on SourceForge:
- SoloAdmin (PHP, remote administration)
- PHPThreadlib (PHP, pseudo-threading)
- NDOORS DDS Texture Conversion Suite (C, open-source converter for a proprietary format)
- CS5 Alt-Key Fixes (Windows automation to restore CS4's hotkey behavior)
Oh yes, and an obsessive-compulsive reader of Jeff Atwood's blog. I have fifteen different articles open as I type this.

CMYK JPEGs extracted from PDF appear inverted Great info, but unfortunately this is not an ICC issue. The image contains the proper ICC profile, the pixels are just reversed. |

CMYK JPEGs extracted from PDF appear inverted @horatio ~ And how would that be lossless? Unless the file output was a different format, that would result in further entropy, which was strictly prohibited by the parameters laid out in the question. You're missing the point. The question is not "How to invert a lot of files," but "How to fix inverse-CMYK encoding losslessly." |

CMYK JPEGs extracted from PDF appear inverted @horatio ~ I'm not sure where you're getting your information. The JPEG format supports an arbitrary number of planes, and CMYK JPEGs are readily available. What part of the workflow are you referring to? The DCTDecode streams are written to disk, and when opened in an editor (including Photoshop), they appear color-inverted. There isn't any more workflow. |

CMYK JPEGs extracted from PDF appear inverted @e100 ~ I am not certain that actually re-encoding the values losslessly is possible, due to rounding errors and the inherent lossiness of the JPEG spec. |

CMYK JPEGs extracted from PDF appear inverted @e100 ~ The DCTDecode stream is extracted bytewise. I would presume the actual number of files to process is irrelevant. A process that works on one would work on all. |

Color loss during colorspace conversions @Mr.Wizard - Rephrased the question slightly, hopefully more to the point, and easier for others with the same question to find. |
