How DNG Handles PGM Data
For image-to-image conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both PGM Grayscale and Digital Negative. Converting within the same category means most properties transfer naturally. Pixel dimensions, aspect ratio, and DPI information transfer directly between formats. When converting from PGM Grayscale to Digital Negative, the conversion is lossless, meaning every bit of data is preserved exactly as in the original.
Converting between image formats is one of the most common file operations. When moving from PGM Grayscale to Digital Negative, key considerations include color depth preservation, transparency support, and compression artifacts. Both formats preserve images losslessly, so this conversion is purely a container change with zero quality impact.
