I'm here for a reason, if your response is contact a/the developer, just don't reply.
For OpenCart products, specially when clients provide some high res pictures, I usually resize images with GIMP. Some image editors tend to lose quality on resizing.Joe1234 wrote: ↑Thu Jan 20, 2022 10:51 amWhat is the best app out there to REDUCE the size of an image (I make sure I emphasize reduce because some apps algorithms will increase better than reduce and vice versa)? I currently use Corel PaintShop 2022 and don't like the quality. Just curious of what, if any, others are using. Yes I know reducing the MP will reduce the size, but the camera I'm using I'm on the lowest setting, so let's just assume using a different camera is not an option for now. So what is the best app out there for the best edges and the least amount of degradation in image?
if your uploaded images do not have the same dimensions as stated in your admin settings, OC will resize those images itself and store them in the image cache.
Those are the images that are served. So whatever software you use for resizing before that, it might not matter.
As with any image resizing, whether via an image software or PHP, the image will blur simply because of the resizing itself and needs sharpening afterwards.
If you do not want OC to resize your images but serve them as-is, you need to upload them in the exact dimensions.
I do not know how many images you have per product and how many different dimensions you define in OC for each.
But doing those manually....good luck.
In OC it is better to add a sharpening process after the resizing of the image as default OC does not do that, you can add an imageconvolution function for that in your image library class.
But this all depends on how important the image quality is for your selling, if you sell mobile phones, nobody cares about the image quality (within reason) but if you sell photographs or paintings, that is a different matter.
Depending on the reason you want to do it there are solutions but you have not specified whether it is quality, detail or file size that is your goal.
You should not modify core files .. if you would like to donate a cup of coffee I will write it in a modification for you.

I've used Preview for resizing. For some quick resizing of a screen capture is ok, but for pictures of products I would suggest another tool.
