TIFF page attributes not being kept
Submitted by Pedro Venda
the 'nona' tool stiches different picture files together to form a panorama. one of its output formats is multiple splits to have the stitching optimized by by the 'enblend' tool. these split images have a page attribute that serves as an offset to place each of them between the other splits that compose the panorama. as an example to illustrate this, one of my panoramas has its split 01 with an offset of +0+0 and split 02 with an offset of +518+35.
when editing and saving any of the above mentioned splits, gimp silently discards that offset information.
example image before editing: pjlv@archon ~/panorama-01 $ identify test-03-split0004.tif test-03-split0004.tif TIFF 1658x2385 1658x2385+2212+138 DirectClass 8-bit 6.90316mb 0.670u 0:02
example image after editing: pjlv@archon ~/panorama-01 $ identify test-03-split0004_.tif test-03-split0004_.tif TIFF 1658x2385 1658x2385+0+0 DirectClass 8-bit 4.362mb 0.500u 0:02
If this is a feature, I think the user should be warned that the page attribute will be lost.
