🧚 SYNOPSIS

QFitsView filename

🌸 DESCRIPTION

okay bestie, QFitsView is a FITS file viewer and it is literally so good 😭🔥 it can display one, two, and three-dimensional FITS files. it's written completely in C++ and uses the Qt widget library, which means it runs on all the major platforms: Windows, MAC OS-X, and a bunch of Unix variants 🌈💅. the main window has a few main areas, and honestly the layout is giving 👑:

• At the top 🔝, there's a toolbar that gives you quick access to the commonly used actions ✨
• At the left 👈, you get:
  • the info of the pixel under your cursor (pixel coordinates, pixel value, and WCS coordinates) 💜
  • a magnifier 🔍
  • a total view of the image 🖼️
• At the bottom 👇, there's the DPUSER command and output window 💻
• Also at the bottom, if you're looking at a FITS datacube, you'll see the spectrum under the cursor 🦋
• The central part of the window shows the actual image 💖

QFitsView has three modes of operation, depending on what kind of data you're viewing, no cap 🧢. for one-dimensional data, the data get shown in an x-y plot 📈. two-dimensional images show up in the main window 🖼️. three-dimensional data cubes can be displayed in a variety of ways, and the third dimension is shown again as an x-y plot at the bottom of the image display 🌈 it's so iconic ngl 💅

🐛 BUGS

⚠️ bestie, heads up: the Debian version of dpuser was compiled without PGXTAL support, which is not supported by the underlying graphics library 😭
