Hello all,

I have to handle massive *.tif files (>40 Gb).

Is it possible to load the tif file not completley in memory but to load only parts of it via the stripe or tiles function?

In this forum I found how to detect if a tif file has stripes/tiles support, but how to I load tile 1..n?

Best Regards,

Harald

Hi

Just set the TIFF_GetTile to return only a single tile:

http://www.imageen.com/help/TIOParamsVals.TIFF_GetTile.html


Example
// Load first tile of a TIFF
ImageEnView1.IO.Params.TIFF_GetTile := 1;
ImageEnView1.IO.SaveToFile('D:\BigBigTiff.tif');
