Nico Weber	5a47e71604	Utilities: Add test-jpeg-roundtrip ... This creates a bitmap filled with a fixed color, then (in memory) saves it as jpeg and loads it again, and repeats that until the color of the bitmap no longer changes. It then reports how many iterations that took, and what the final color was. It does this for a couple of colors. This is for quality assessment of the jpeg codec. Ideally, it should converge quickly (in one iteration), and on a color not very far from the original input color.	2024-01-14 11:35:40 +00:00
