Even, Argh, I typed "unsigned char" when I meant "signed". Changing GDT_Byte to *signed char* is too big of a change, I guess? I like the plan for PIXELTYPE. Sorry about the noise, everybody! On Tue, Nov 8, 2022 at 5:04 PM Even Rouault wrote: > Sean, > > > Changing GDT_Byte to unsigned char i

Sean, Changing GDT_Byte to unsigned char is too big of a change, I guess? I can work with that. GDT_Byte semantic is already unsigned char / uint8. What did you mean? Is there any advantage to a GDT_UInt8 type that can't be changed by a PIXELTYPE option? That would be super confusing if w

Sorry, please disregard my previous email (from my phone at lunch). I had a poor recollection of the GDALDataType enum. Changing GDT_Byte to unsigned char is too big of a change, I guess? I can work with that. Is there any advantage to a GDT_UInt8 type that can't be changed by a PIXELTYPE option?

Re: [gdal-dev] Call for discussion on RFC 87: Signed int8 data type for raster

Yes please! The friction from not having GDT_Int8 keeps coming up again and again. It is extra rough on beginners who hit this case. But I would like to hear any voices for not doing this incase there is something I haven't thought of. On Tue, Nov 8, 2022 at 2:43 AM Even Rouault wrote: > Hi,

Hi, I've posted in https://github.com/OSGeo/gdal/pull/6634 a new RFC to add a new GDT_Int8 data type, for signed 8-bit integer data, to the GDALDataType enumeration, which cleans up the current support we already have for that data type. Even -- http://www.spatialys.com My software is free,
