Topic: PS CS border on save (Page 1 of 1)

wondering if anyone knew why i get a slight border on the images upon save for web???

see http://www.freewebs.com/fatrod/index.htm

Maybe the edges had slightly translucent areas before you saved it. Maybe it's just JPEG. Either way that image should definitely not be JPEG.

do JPEG's often have this issue? I have never had this problem with JPEG's in previous versions of Photoshop...

GIF then?

Thanks for the tip.

I don't remember running into this with JPEGs generated from images with completely opaque pixels, but that's just the thing with JPEG - the artifacts from lossy compression make it imprecise. Like I said though it's academic - that is not a photograph & has no business being JPEG.

It rather looks like a bicubic interpolation artifact. You must have resized the whole image/layer and ugly bicubic contrast bumps have been introduced.

I usually avoid bicubic like the plague, but when I have to use it, I duplicate the layer and merge these "twin" layers again and again to get rid of the artifacts on the border.

HTH

one last note: It's definitely not JPEG artifacts. Those appear on 8x8 squares, due to the DCT, especially in areas with high frequencies. They result in very local patterns of frequency noise. ( i.e. small stripes or set of dots of undesired contrast or bleeding color )

most of ^ went straight over my head

have upgraded my version of PS and i am not suffering from this problem any more!!
