I'm running Magento 1.8.1 and after upgrading my server to PHP 7 (And applying a heap of compatibility fixes) I'm still having issues with my product images appearing very grainy. It doesn't seem to be a common PHP 7 compatibility issue that is discussed.
As well as upgrading to PHP 7 (In preparation for M2) I also requested the following PHP extensions to be installed;
- PHP Extension intl.
- PHP Extension bcmath.
Maybe these could have effected things?
- I have checked the uploaded image files and they are fine so the Magento image helper could be to blame.
- I have tried improving the image by overriding the image quality to 100 on the setQuality() Mage_Catalog_Helper_Image - It didn't improve at all!
- I have ensured the image cache is cleared.
Any ideas guys?
UPDATE: I just found by disabling the watermark, I am getting a perfect image!
