Hello, dear developers.
I looked a demo, but couldn't estimate some important moments for me:
1 . It is possible to work with big raster files (more than 4 Gb)
2 . As quickly there is a drawing of vector objects (about 100000)
3 . How objects in a window are drawn? in total at once or only what get to window dimensions?

Thanks.

Hi

1. If LegacyBitmap is false and Location is ieFile then ImageEn should handle large raster files

2. You are likely to have performance problems with vector files with that many objects

3. ImageEn draws only what is visible onscreen

Thanks, 2 more questions:
1. Whether work with multi-channel images is possible?
(for example: http://www.digitalglobe.com/node/462)
2. Whether isn't present at a vector of property which establishes a threshold for object drawing. For example at a small zoom not to draw objects less than 1 pixel?

Additional channels (ie for TIFF) are just discarded.

Objects are always drew, at any level of zoom.

Why TIFF images (both 1 channel and 8 channels) from this source aren't displayed?

It is impossible to choose what of 3 channels to display?

It is a pity. It can well help with drawing speed.

I understood, what full testing is possible only upon purchase ImageEn? If I don't accept the speed of components, whether I will be able to receive money back for this reason?

Please post or send by email the un-loadable TIFF.

No, I'm sorry.

I didn't find how to send archive = 10 Mb
in archive 2 files:
11APR03001446-M2AS.... TIF - multichannel
11APR03001446-P2AS.... TIF - panchromatic
