Embedded transparency in TIFF

Post by Walli » Mon Sep 14, 2009 8:45 am

Hi,

I have a set of tif files that is lzw compressed and want to batch resave them with xnview, so that the files are uncompressed.
That works, except one big problem:
Tif files that contain transparency (have been created with Photoshop) don´t come out right. The color layer is dropped to a black background and an alpha channel is created.
But I would like, that the embedded transparency is kept and no alpha channel is created - I didn´t find anything in the options. Is it possible to keep the embedded transparency instead of converting it to an alpha channel?

thanks,
Walli

yes, currently transparency saved by photoshop is not kept, TIFF must be in RGBA
