[GIL] How to create (and read) a 4 pixels per sample image type?
Hi all, I am currently trying to create and read an image which has 4 pixels per sample. Here is the output of tiffinfo on such an image : TIFF Directory at offset 0x8 (8) Image Width: 2273 Image Length: 2256 Resolution: 72, 72 pixels/inch Bits/Sample: 16 Sample Format: unsigned integer Compression Scheme: None Photometric Interpretation: RGB color Extra Samples: 1<unspecified> Samples/Pixel: 4 Rows/Strip: 2256 Planar Configuration: single image plane How can I achieve this gola with GIL? Best regards, Olivier

I understand you have a 4 channels per pixel which of each channel is 16bits. Is that correct? Also, the color space is rgb. Did you try to use a rgba16_image_t? Regards, Christian
