CropSize Magic

Using CropSize I am now able to have a more streamlined workflow for managing my wife’s website images. She is an artist, and so I have to work with a large number of images.

Some while ago I devised a scheme whereby artwork info could be embedded in the IPTC section of a jpg file . . . Title, Medium, Dimensions and Portfolio. I used IPTC fields Heading, Caption, Supplementary Category and Category to hold the information.

I upload the full size image file embedded with the IPTC data I need. Using PHP and a little JS, I extract the IPTC information from the jpg file and use it accordingly, while at the same time create a thumbnail for each portfolio front page.

All worked well when I could sit or stand at my iMac and use Lightroom. Medical reasons presently prevent me from doing so. But I can readily work while reclining in a lounge chair with an iPad Pro, Apple Keyboard and Pencil.

Lightroom CC for iOS is nearly worthless, so I’ve spent the last 3 days investigating means to accomplish what I need. CropSize does exactly what I needed for editing IPTC data.

My only wish list item is to be able to load image files from a location other than iOS Photos. My website images are in the website directory, so I have to copy an image to Photos, process with CropSize and then copy back to the original directory before ftp to server.

So again, thank you for producing such a great tool and providing it a very reasonable price.

Functionality I missed from Optics

Ever since the old "Optics" app went kaput I've been aching for a replacement. I finally found this one! Optics had the pixel-accurate cropping via the dimensions-displaying selection marquee and an eyedropper tool. Apple's screenshot tool has an eyedropper, so I still needed the measurement/cropping tool. I'm so happy to find this app! 😃😃😃😃😃😃😃

Now I just need one small tweak: one of the things I loved about Optics is that the zoomed image was NOT antialiased. This app blurs the edges, which makes it very difficult to find the actual edge of an object within the image. Please let me see the pixel edges crisply. Thank you.

Developer Response ,

Thank you for your review. We will consider to implement such a feature in future versions.

The best image cropper on iOS (but please add one feature!)

This is the best image cropper on iOS. And you can buy it outright! Every other app on here wants criminal amounts of money to subscribe to a very basic image editing feature.

Developers: Could you please let us add negative space to our images from the crop screen? As in: pulling the crop guides past the image to create a canvas beyond the original photo. (Let us pick the color of the negative space too, please.)

Developer Response ,

Thank you for your review. We'll consider adding this feature in future versions. For now you can use combination Resize / Canvas Size + Crop to achieve the same result.
