Hi, I am trying to load a BLOB file with size 210 MB into TImageENDBView. This is causing EoutOfMemory Exception. I have attached the callstach for your reference. Can you suggest me what can be done to address this?

Hi

What version of ImageEn are you using? What type of image is being loaded from the blob? Have you set TImageENDBView.LegacyBitmap to false?

ImageEN 5.0.5 is what we are using. We did not get Images of that huge size so, I stored Video into that BLOB. So, It is a video that we have stored in BLOB. Should we handle Videos and Images separately?

Hi

LoadPicture/LoadPictureEx does not support video loading.

But, I am not using LoadPicture/LoadPictureEX specifically. We have just bound the BLOB column to TImageENDBView component and when the ADOQuery is fetching the rows from DB, the component is internally calling this method, which is causing the exception.

Hi

OK, why not set AutoDisplay to false:

And then call LoadPicture as required.

Thank you!! I have got it resolved this way. I am now loading pictue only when it is Image Type else I would load the default player for Videos and open the videos in that player. Is there any ImageEN component? If so, What is the component we should use when Video has to be loaded?

Hi

If it is a compatible format you can display it in a TImageEnView (see the demos for assistance), or Delphi's TMediaPlayer.
