Photoshop CS5: Image Size 8.125 is not Accurate

[ylwdog]

I am trying to add canvas to an existing image to make it exactly 8.125 and PS will not allow me to achieve this exactly. It will make it 8.123 or 8.127, it will not allow me to align a second image at 8.125 on the canvas either. I have tried zooming in to 3200 magnification level and that has no affect.

Thanks

Well it depends on what the pixel dimensions are of your current image and what resolution you have specified. If you are trying to increase the size of something by 2/10th of 1 percent and that something is 300, then you have a problem because you can not have 6/10th of a pixel. You'll need to check the physical number of pixels and resolution and do the math. You may need to resample the image prior to changing the canvas size.
