Saving 16bpp TIFFs ?

[Todd Gibbs]

Hi Guys,

Does anyone know how to save a 16 bits-per-channel TIFF (48bits per pixel)
? I can save them as 24bpp RGB or 32bpp ARGB but cannot find how to save as
48 bits per pixel. Im sure TIFF supports 16bits per channel.

Thanks in advance.

Todd.

Sorry, I mean to put 48bpp TIFFs in the subject line....

AFAIK the GDI+ encoders for 16 bit are broken and they never did 48bpp.

As an alternative I suggest you take a look at the FreeImage library.

Thanks Bob,

I will take a look at FreeImage, although I assume I will have to rewrite
the rendering of my application to get it working rather than just 'slot' in
their save function.

Regards,

Todd.

Hi,

Just to close this thread, I solved my problem by using the tifflib library.
It takes a little bit of coding but is a fine solution
