Posted: 2013-08-14T08:57:36-07:00
Dear community,
after trying for 2 hrs I think it would be better to come here for help. Here is the description, thank you in advance for any hints.
----------
WHAT I WANT: to resample A 300ppi jpg Image to 72 ppi
WHAT I GET: a resampled jpg image with a resolution of "300 x 72 ppi"
SCREENSHOTS:
original
resampled
My Code:
NOTES:
I also have had tried following codes:
- $image->setResolution()
- $image->setImageResolution()
And with all possible combinations, it didn't change anything.
Thank you very much for any hints.
