I see this error message at converting TIFF file (10MB) to black-and-white (ordered).
I have 634 GB of free disk space & 16 GB of Ram.

I can send this file for testing.

What code are you using?

Is it a multipage tiff?

One page

ImageEnView1->IEBitmap->Location = ieTBitmap (I need to edit this file)
ImageCacheSize = 1

Hi

TBitmap is not good with large files. Are you able to do your editing using ImageEn's GDI+ features to avoid changing to TBitmap mode?

>ieFile - Uses memory mapped files. Canvas not available. Used for big images.

What actions with canvas aren't available?

Hi

Sorry, I gave you bad information, even using GDI+, it will make use of the canvas, and so convert it to TBitmap mode.

What canvas activities are you performing?

Hi

Any action on the Canvas to IECanvas will convert the location to ieTBitmap.

Yes, you can use it as long as you do not access the canvas.
