RE: [GD-DEVEL] Noise problem

I just tried with Php 5.2.6 and I've got the same result...
But I have made more test on the problem :- I take a white square picture 1000x1000px in jpg, quality 100 made with photoshop- I resize it with ImageCopyResampled to 300x300px and I heve got the resulting picture. If you change the brithness in Photoshop you can see the noise : testresized_brithness.jpg
 
BUT if you do the same with a size like 200px you don't have this noise ! It seems that if the orginal size is a multiple of the target size you don't have this kind of problem...
More over you can see that the size of the picture increase !! What a shame...Any idea ?
