Subject: Regarding an earlier reply from you

Hello Michel,

In an earlier post regarding memory slowdowns of my software you suggested making the call to create a TTiffGraphic outside of the scan call, so as to avoid the create and destroy every time. That got me to thinking...

1. I am not scanning my tiffs multipage, they are all single page tiffs. So if i create the ttiffgraphic outside the scan call, will it just keep growing in memory while my software is pulling in images and saving them out as singlepage tiffs?

2. The above is why i am creating it and destroying it after each image is pulled in and then saved out. Memory usage is a big problem here.

3. I also thought i should mention this time, that i am not using Envision to scan. I am using the Pegasus ISIS scanning control to aquire my images.

4. This is the reason why i have it setup right now to use the imageformattransform to set the image format to ifBlackWhite in the beforesave event of the imagescrollbox control. Is this necessary? The image files seem to tend to be smaller with this code in place, but i wonder if it is at the cost of memory. Is there any way to specify that all images are to be saved in the ifBlackWhite format, so i do not have to use a transform before saving each individual image? I believe that might help on the memory issues as well. And along the same note, is there a way to also specify the compression for all files, to avoid setting the compression for every file in the beforesave event of the imagescrollbox component?

Thanks in advance for any help you can give,
