Let' assume i have 2 pictures:
Picture1: 500px*375px
Picture2: is resized Picture1 (200px*150px) saved in a photo editor without(!) compression. Both pictures have maximal quality.
Then I upload both pictures to ez publish. My image.ini.override:
[MIMETypeSettings]
Quality[]=image/jpeg;75
[GD]
IsEnabled=false
[ImageMagick]
IsEnabled=true
[small]
Filters[]
Filters[]=geometry/scalewidthdownonly=100
Now i have:
'small' variation of Picture1 is about 25KB 'small' variation of Picture2 is about 5KB Both 'small' variations are almost identical - pixel-to-pixel, but size differs drastically. I can't understand it: i tried to resize both pictures in adobe photoshop with q=75 and size=100px*75px and result pictures have same size. What's going on? Is it incorrect resizing in ImageMagick or my mistake in settings?
