Hi Guys
I'm trying to alter the resolution of an image and
then redraw it.
I've created an NSImage from a .jpg file. I then look
at it's size.height and its NSImageRep's pixelHeight
to calculate it's resolution. If the resolution is
above 300, I reduce the pixelHeight and pixelWidth of
the NSImageRep whilst keeping it's size the same so
that I get a resolution of 300 (which should decrease
the image area on the screen once I assign the
NSImage to an NSImageView). But it doesn't seem to
make a difference.
Is there a way of getting the NSImage to take notice
of the altered values in it's NSImageRep and draw the
image appropriately?
Or is there another way of doing it?
Any help appreciated.
