Hello, I'm using imageenmview to display a tif image with memoryStream via method: MIO.LoadFromStreamTIFF. images with size 75mb or larger in size the delay is extremely large, and in some cases cause out of memory. What can I do to improve this?

Hi Tiago

What version of ImageEn are you using? Can you upload your TIFF file somewhere so we can test it here?

Hello Tiago

Did not it work to change the StoreType property?

Do you need to load several large TIFF files into your project? then the StoreType property should be changed to ietThumb.

Do you need to manipulate these images, or just display on the screen?
Please provide more details to help you find a way out.

Kind regards.

your suggestion improves performance but destroys the quality of the image to the point of being unreadable

Hi Tiago

What are you looking to do? Are you displaying thumbnails of the TIFF, and then showing a full size version of the TIFF elsewhere? If so, for performance you should use StoreType ietThumb and then load the full quality image into the TImageEnMView:
