Hi,
When opening a Tiff file our application is throwing an Out of Memory error. I have applied Mad Except to our executable and the call stack was pointing to the below ImageEn component lines.

Can you please advise is there any special check to be made to fix this issue. This issue is not happening all the time, it happens after the application uptime of 5 hours. Please advise

It would be much easier to assist you if you show your code. Having said that, you should look at the Aborting property.

try
  ImageEnMView1.MIO.LoadFromStreamTIFF(iMemoryStream);
  finally
    if ImageEnMView1.MIO.Aborting = True then
    { The image failed to load }
     exit;
  end;
end;

I guess the real question is why is the out of memory error occurring? Without knowing how many frames are in the tif file and the size of the bitmaps and if you are using 32-bit or 64-bit it is difficult to answer this question. Perhaps you can provide more details.

Hi,
Our application is using TImageEnMview component to first load the TIFF file which may contain 10 or more pages which are of black and white,then use TImageEn view to show one page at a time, when user clicks on next page we show the page accordingly. This is where the Out of memory occurs to the users when they scan gthrough next pages using next button. I have attached the code on we are reading the scan document and showing and the code for showing next page.
Please advise

Hi

This does not seem to be an ImageEn issue.

I did not see anything obviously wrong with your code, though why do you call:

Image1.Bitmap.FreeImage;

Hi,

Just to make sure the previous image is cleared and not hold up memory and that's the reason it was added.

Is there a conference number that I can call you to discuss with you and show the issue in Team Viewer? Please advise

Hi

I'm afraid we do not offer phone support. Also, try to confirm that this is actually an ImageEn error, e.g. replace the database calls to load from the same image from a file into a stream. Narrow down the problem to find where the memory is actually being leaked/corrupted.
