Global variable initialization in packages Very nice explanation. Your absolutely right. I did not consider the usage of global variables in this way. |

Wolfram Workbench - how to rename local variables Perfect. I wonder if there is some other possibility using "Refactor". I tried to use the Refactor > Pattern Replace on a code selection, but it applies to the whole code instead of only the selection... |

Why does ImageData need four times more memory? Thank you for the good explanation. This really helped me a lot :) |

Why does ImageData need four times more memory? @SimonWoods: Nice ideas, thanks. I tried to store different types of images. The memory increase seems to be independent from the type. It must have something to do with Mathematica's representation and memory allocation for lists. Am I missing something completely?! |

Why does ImageData need four times more memory? @LeonidShifrin: Good idea, thanks. I wanted to post an example where the difference in memory of both import types can be seen easily (104905128 Bytes vs. 419492208 Bytes). If needed, the dataset can be reduced to 10 images if you use: ConstantArray[Image[ConstantArray[0, {1024, 1024}], "Bit16"], 10]]; |

Why does ImageData need four times more memory? @cormullion: Thanks for your ideas. I have read about these two functions, yes. Usually, my files should fit into the memory without any problem. The thing I am curious about is why the array-representation needs four times more memory. |

Why does ImageData need four times more memory? @Lou: Thanks for the link. I already read this post. However, the problem is not that memory is not freed. It's not about the history of the current session. My problem is that I do not understand why an array-representation of images needs four times more memory. |

Maximum size of TIF files in Mathematica Thank you for your answer. I tried reinstalling the java link with different settings for the default amount of memory Java can allocate. I also tried to set it up to 4000 MB. After each reinstall, I restarted Mathematica. Unfortunately, this did not solve my problem. I also verified that the file size is limited by 2GB by testing different numbers of images. The export does not export more than 2GB and no error message is generated. |

Maximum size of TIF files in Mathematica Thanks for your comments. On Windows 7 (64 Bit) I am not able to export the file. Do you know of any options or settings in Mathematica that may cause this behavior? |

Maximum size of TIF files in Mathematica I usually open the files with FIJI or ImageJ, respectively. Both are open source. Could this be a OS problem? I am using Windows 7... |
