Such files get more and more common. |

Hi
These are *massive* files. We are just investigating whether it is practical to sort them.

I use the same command
ImageEnView1.IO.Params.TIFF_ImageIndex := index;
ImageEnView1.IO.LoadFromFileTIFF('D:\MyImage.tif');
after editing this page I use
ImageEnView1.IO.ReplaceFileTIFF(...)
ps
> I recompiled as Win64
What program and version do you use? |

ImageEnView can only load a tiff file with one page so are you specifying the index of the multipage tiff file to open?
// Load the second image in the MyImage.tif file
ImageEnView1.IO.Params.TIFF_ImageIndex := 1;
ImageEnView1.IO.LoadFromFileTIFF('D:\MyImage.tif');
Your discussion so far is not providing sufficient information. Try making a demo to show what you are doing and provide a sample image you are testing so we can be more helpful.
I did some testing here by adding images to a multiframe tiff file to try to see what happens when too many images and too much memory is required. I added the images to ImageEnMView and also added them to ImageEnView on a pagecontrol which inflates memory requirements. After adding 135 images when compiled with Win32.. no problem. After adding 235 images I got out of memory errors. I recompiled as Win64 and added 235 images with no problem.
My point of all this is ImageEn does not provide unlimited ability to open or save huge images. By compiling for Win64 the number of images that could be opened or saved increased. I have no idea
Nigel, Can you provide some guidance as to how to estimate the number of frames of a specified dimension (ie. 1024x768) that can be added to ImageEnMView for a given target platform- Win32 andWin64 for a pc with a given amount of memory available (ie. 8 gb- 16 gb.)?

I suspect this is a memory problem. 500 pages is quite a lot. What components are you using to load and display the images?
