Adding an image attribute to tiff.c

Hi,

I am dealing with some TIFF images from a vendor and they
have put some
information I need in the TIFFTAG_HOSTCOMPUTER attribute.

I couldn't seem to be able to access this from PerlMagick,
so I added the
following lines to coders/tiff.c

616a617,618
>     if
(TIFFGetField(tiff,TIFFTAG_HOSTCOMPUTER,&text) == 1)
>       (void)
SetImageAttribute(image,"Host_Computer",text);
1876a1879,1881
>    
attribute=GetImageAttribute(image,"Host_Computer"
;);
>     if (attribute != (const ImageAttribute *) NULL)
>       (void)
TIFFSetField(tiff,TIFFTAG_HOSTCOMPUTER,attribute->value);

(I don't know if you have a standard naming policy, so I
just used
Host_Computer)

Is this of any use to the source code?

Or is there another way of getting this information from
PerMagick? (Sorry I
am not really a C programmer)

Thanks

Adam
