Convert bigTIFF to pyramid bigTIFF

[Janpan]

Hi,

I have a bigTIFF with ~4.5GB that I want to convert into a ptif (pyramid TIFF).

Conversion into bigTIFF works for those files and conversion to ptif works for small Images.
But I'm wondering if there is a possibility to convert an image into a pyramid bigTIFF combining the options ptif and TIFF64?
Using the command:
convert image1.tif ptif:image2.tif
my win7 Workstation quits with error
TIFFAppendToStrip: Maximum TIFF file size exceeded.
and File is 4GB in size...

Thanks Janpan

Hi,

I think it is a generally unsupported feature to build multipage bigTIFF, is it?

Are you using the x64 version of ImageMagick?

[Janpan]

Yes, ImageMagick-6.8.7-4-Q16-x64-dll on win7

I am sorry but I misunderstood your question. You are right you cannot combine those two options at the moment. Maybe we should introduce something like this:

Code: Select all

convert image1.tif -define tiff:pyramid tiff64:image2.tif

Hi dlemstra,

yes, an option like your suggestion would solve my problem. But I am not sure weather multipage bigTIFF is currently supported in ImageMagick or not. An as far as I understood a pyramid TIFF in general is a multipage TIFF. Can anyone say something about multipage bigTIFFs? This would be a suitable workaround for the moment.

Thanks
Jan
