Hi All, I am very beginner in this tiff field, If I say something silly, please excuse me. I am writing an application to convert/save tiff image into buffer and then back to image from buffer. For this, I need to handle all types of images. I am having trouble with tiff 16 bits signed/unsigned integer and 32 bit float images. Does this 16/32 bit means they are colored images or they can be greyscale too ? I am using TIFFReadScanline to read the datas, but the problem is my buffer(this is constraint) is char* and how can I access this data if they are 16/32 bit ? And also, how does this data relate to bpp,bps and spp ? I mean can 16 bit means 16 bit for R,G,B each or 16 bit in total for R,G,B; and same with 32 bit ? Thank you very much for your help. Best, Keshab
