Pixel equalizer in PSP9?

Hi all,

I bet this is the wrong espression but I am an absolute beginner in digital
photography and image processing, let alone PSP9 trial. Maybe my question
could be answered by scavenging more thoroughly throug PSP9's help, but
trial time is limited!

QUESTION: after having put together different layers with different pixels
per inch each, can I average or equalize the total pixels?

E.g. I have a background of X pixels per inch, paste to it my person cut out
from a different picture with Y pixels per inch, and add another cutout from
another source of Z pixels per inch (Z being the lowest resolution). Is
there a magic command "total pixels be an average of X, Y, Z!", or "total
pixels be all Z!"?

Otherwise the image would look kind of strange, with different image
elements having different resolutions!?

Thanks,

Siggi

The ppi is only used when printing. An image open on your desktop will in
pixel's by height and width, the PPi that you set for the image that you
pasted the rest on will be the only ppi remembered. Do Image > resize to
change if need be before printing

Your concern with pixels per inch (PPI) is unfounded, Siggi. In the
computer, on the screen, and on the disk, an image has a width and
height in pixels. Period. PPI matters only on paper: when printing,
PSP tells the printer how many pixels to lay down on each inch of
paper. When scanning, the scan software tells the scanner how many
pixels to pick up from each inch of paper.

Any number at all will do for PPI in the computer, on the screen,
and in a file. Indeed, many common image file formats do not store
PPI at all because it is irrelevant.

You can try this for yourself. With an image open, Image > Resize.
Uncheck "Resample using" to keep PSP from changing the number of
pixels in the image. Change the number in Resolution and click OK.
Observe the change in the image--there isn't any. "Save As" giving
it a new file name. Compare the new and the original image. They are
identical.

When the time comes to print, then you control the size on paper by
setting PPI. It applies to the whole image, not to individual
layers.

and printing at http://www.scantips.com.
