Tiff Format JpegCompression - Quantization Table

Post by asdfgh41 »

I want to convert jpeg image to tiff. While converting to tiff, i'm using jpeg compression with 25 quality for reducing file size.
But when i try this process with photoshop or atalasoft i get better resolution and smaller file size. I think cause of difference is quantization tables.
Also it looks like magickimage decompress and recompress jpeg file while converting jpeg to tiff.
I can set quantization tables for jpeg format which are similar used by photoshop and im getting similar results.
But i can not set quantization table for tiff format. How can i set q tables for tiff (jpeg compression) or set default quantization table for all jpeg processes?
