I'm very excited to announce the 1.0 release of Perspec!
Perspec is a desktop app for correcting the perspective of images. This is primarily useful for photos of documents and receipts, but it can be used for any kind of image.
This has finally become the app I envisioned when I started working on the project 9 years ago. I didn't think it would take me this long to get here, but I'm very happy with the result and I hope you'll like it too!
Initial Motivation
You're probably familiar with the scanner apps available for mobile phones, like Adobe Scan, vFlat, SwiftScan, … and numerous others. Scanning functionality is also integrated into Dropbox, and these days even natively into iOS itself.
However, I don't like working on my phone and I'd rather just take photos of the documents and receipts and deal with cleaning them up and organizing them on my computer another day. There, I have a big screen, a keyboard, and a precise mouse, which makes editing faster and more accurate.
Also, the mobile apps make some annoying technical decisions in the name of giving users something they're familiar with.
For example: If you store a document as a grayscale PNG, you can get small file sizes without introducing any compression artifacts. However, all the popular apps will give you a grayscale JPEG image with a much bigger file size and worse image quality, just because JPEG is what people are familiar with.
Or maybe I'm giving them too much credit and they actually don't know that PNGs can be smaller than JPEGs if the image contains large areas of uniform color, whereas for normal photos, JPEGs are smaller than PNGs. And no, converting it to PNG afterwards is not an option, as by then the image already contains all the JPEG compression artifacts.
