For some unknown reason, adding a simple string to the InfoText, for a 500 image IEMulti Imagelist is taking a super long time, like 1 second per thumbnail.
It is not a 32/64 bit issue, but rather in my production application taking forever long.
When I do this in another simple app just doing it, the process does not take that long.
Image Statistics: 66mb in size, 496 TIFF images inside the file
Any help/hints/issues with the following code?
// 500 page document
Stopwatch myTimer = new Stopwatch();
long loadTime=0;
long thumbNailTime=0;
myTimer.Start();
ieMulti1.ImageList.LoadImages(@"C:\batches\20220120-3333-0001.tif");
myTimer.Stop();
loadTime = myTimer.ElapsedMilliseconds;
myTimer.Reset();
ImageInfoClass imginfo;
IOParams imgIOParams;
for (int i = 0; i < ieMulti1.ImageList.ImageCount; i++)
{
//imgIOParams = ieMulti1.ImageList.GetIOParams(i);
imginfo = ieMulti1.ImageList.GetImageInfo(i);
imginfo.InfoText = i.ToString();
}
myTimer.Stop();
thumbNailTime = myTimer.ElapsedMilliseconds;
this.Text = "Load time: " + loadTime.ToString() + " Thumbnail Time: " + thumbNailTime.ToString();

I have a workaround, but I don't really want to use it.
if I make the iemulti window not visible, it is significantly faster, but gives the application a blank window when doing so.
ieMulti1.Visible=false;
<Thumbnail code here>
ieMulti1.Visible=true;

Thanks Nigel! I like this better, however it is no faster, but the screen isn't blank! Thanks again!
I rewrote a read only console tool to read the TIFF file name from the image file, and it is slow also, obviously not a GUI component here. Is it the way I am doing the read? 1009 page TIFF file takes 55 seconds?
1000 - Name: 117-118-0016 Number: 0
1001 - Name: 117-118-0016 Number: 0
1002 - Name: 117-118-0017 Number: 0
1003 - Name: 117-118-0017 Number: 0
1004 - Name: 117-118-0018 Number: 0
1005 - Name: 117-118-0018 Number: 0
1006 - Name: 117-118-0019 Number: 0
1007 - Name: 117-118-0019 Number: 0
1008 - Name: 117-118-0020 Number: 0
Reading TIFF Pagenames on 1009 images took 55 seconds.
Stopwatch myTimer = new Stopwatch();
myTimer.Start();
IEMulti img = new IEMulti();
inFiles.ForEach(delegate (string fileName)
{
img.ImageList.LoadImages(fileName);
Console.WriteLine("{0} Pages: {1}", fileName, img.ImageList.ImageCount);
for (int i = 0; i < img.ImageList.ImageCount; i++)
{
IOParams myIOParams = img.ImageList.GetIOParams(i);
Console.Write("{0} - Name: {1} Number: {2} ", i, myIOParams.TIFF_PageName, myIOParams.TIFF_PageNumber);
Console.WriteLine();
}
});
myTimer.Stop();
Console.WriteLine("Reading TIFF Pagenames on {0} images took {1} seconds.", img.ImageList.ImageCount, (myTimer.ElapsedMilliseconds / 1000).ToString()); |

Hi
Is the slowness in the loading (expected) or the reading of params (unexpected)?

| Again Nigel, you are right. It's a 125mb file, so it's the loading, not of the params. I guess that's just how long it takes to read a large file, or decompress it or something. |

Any suggestions on reading a 100mb into the tool quickly? 1000 pages is the limit to what I want them to do. The concept of saving a 'snap' is a HUGE savior!

Hi
You can use LoadSnapshot() and SaveSnapshot().
Or you can load images on demand using the format fullfilepath::imageindex, e.g.
ieMulti1.ImageList.AppendImage(@"C:\batches\20220120-3333-0001.tif::0");
ieMulti1.ImageList.AppendImage(@"C:\batches\20220120-3333-0001.tif::1");
ieMulti1.ImageList.AppendImage(@"C:\batches\20220120-3333-0001.tif::2");
etc.
