    I've got an image that however I resize it PS seems to add, or change the colour of approx 1 pix of the edges.

    This is a crop of the original image,1-image-2.jpg

    and this is what happens if I resize it (smaller) image-1.jpg

    I've tried all sorts of options but nothing seems to work, anyone know how I can remedy this please?

    I'm not sure, but is there a setting to switch off anti-aliasing when re-sizing? I am just starting out in photoshop so can't help any more than that.

    On PS elements i just choose the "Bicubic Sharper (best for reduction)" option. But i don't think this will help.

    If you have a pic 10 pixels wide and want to reduce it to 5 pixels wide, then every colour transition between 2 pixels will need to be crammed into one so it gonna averate the 2 pixels into 1, B&W give grey.

    If there is an option that won't average the pixels but will just choose one or the other then you will get what you want. Sorry i don't know what this is called.

    Hello K
    Forgave me if I've misundertood you. Is this what you mean
    To put a 1pixel line around the edge
    In Photoshop Control P that will give you the marching ants around the edge
    From the Edit drop down select stroke ,set to 1 pixel, you have trhee choices, inside, centre or outside, Pick INSIDE.
    Select the color you require then press OK.
    That will give you an equal 1 pixel boarder

    Hope this is what your asking

    Bill

    Hi Bill, no, sorry maybe I didnt explain myself properly. The first image is larger than I need for the space I want to put it in, but when I resize PS puts about 1 pix around the edge of the black shapes and thats not what I want. I want to resize but keep the shapes in tact.

    Thanks Stuart, I've tried using bicubic sharper but that doesnt work.

    Laurel thanks but cant you put your answer here, it might help others?

    In Paint Shop Pro (well the old version I've got on the pc at work) - there is an option in the resize dialog of 'pixel resize'. I've just tried that on a similar image and it works a treat - nice clean edges. Is there something similar in PS? I don't have PS here to experiment on and besides I'm supposed to be working Smile

    Think it's to do with Anti Alias

    The above is a little tutorial that should help.
