Hello, I'm trying to read TIFF files 104 with 400Kb each, with the following code:
iPosicao: = iemvThumb.AppendImage;
iemvThumb.SetImageFromFile (iPosicao, sArquivoDestino);
When iPosicao is = 68 an error occurs in "Out of Memory" in the line of the method SetImageFromFile.
I'm using version 3.1.2, Delphi 7, Windows 7 64 bit, at the time the error occurs have more than 2 GB of Memory available.
What should I do?
Please rename the file extension for TIFF.
Sorry for the English, PT.BR. |

| I cannot replicate this problem using last version. I tested your image with Delphi 7 and Windows 7 - 64 bit. Old ImageEn versions had problems handling pointers with locations >2GB. |

Even in a 400KB file with? ImageEn Version 3.1.2.
It has some code to work around this problem? |

| Yes, even with 400KB file. It is not important the buffer size, but where the operating system allocates it (if pointer_pos > 0x80000000). |

Hi Fabrizio, could circumvent the problem of "out of memory" using TImageEnMView.MIO.LoadFromFileTIFF who read specific files with the extension. Tiff, and also using BeginSelectImages and EndSelectImages.
Thanks. |

Sorry, I don't understand very well the question.
You call LoadFromFileTIFF, so you can avoid TIFFs.
Also, current version hasn't the Out Of Memory problem. |
