Hi I am struggling to save my data in (Geo)TIFF files with the proper creation options. My data is not standard RGB(A), but a collection of bands like red, green, (not necessarily blue), another type of red, near infrared, etc, and Alpha. It can be uint8, uint16 or float.
I was using PHOTOMETRIC=MINISBLACK and ALPHA=YES, but now I am not sure if this is the proper configuration. In addition to that, I am setting a ColorInterpretation to the bands (many bands as GCI_Undefined, like for Near Infrared. The alpha band is clear as GCI_AlphaBand). The "extra samples" is obscure to me, I do not know how many bands expects, and how many are "extra". ( https://www.awaresystems.be/imaging/tiff/tifftags/extrasamples.html) TIFF says "There is no default for PhotometricInterpretation, and it is required. Do not rely on applications defaulting to what you want." in https://www.awaresystems.be/imaging/tiff/tifftags/photometricinterpretation.html How should I create my TIFFs? Thanks. .___ ._ ..._ .. . ._. .___ .. __ . _. . __.. ... .... ._ .__ Entre dos pensamientos racionales hay infinitos pensamientos irracionales.
