EZView v1.14 & QOIPP.h An Image Viewer application

Welcome to EZView, A freeware image viewer application which supports the most common image formats such as bmp/dib, gif, tiff, png, jpeg, wmf, emf, ico and cur image formats.

I have seem numerous image viewers but none of them provided exactly what I wanted. For such a simple requirement some of the viewer programs I have used were overly complicated or had special requirements.

What I wanted was a nice flexible program, small in size, unobtrusive and easy to use.

So with that in mind here is a list of EZView features:

• The size of EZView.exe itself is less than 170k meaning the program loads up quickly and impacts system performance as little as possible.
• Slideshow support is provided with every image in a directory being displayed one by one.
• The most common image formats e.g. bmp, jpeg, tiff, png and gif are supported. Some programs try to support every file format under the sun with support for formats which you are very unlikely to meet in day to day use.
• Full - screen mode is provided allowing you to preview the image without having other windows interfering.
• Simple zoom functionality is also included.
• Support for animated gifs and multi-page tiffs.
• Supports auto rotation of images based on EXIF/ITF orientation tags.
• Supports all images formats supported by the underlying WIC codecs. On modern version of Windows 10, the formats EZView support include BMP, GIF, ICO, CUR, JPEG, PNG, TIFF, Digital Negative (DNG), Windows Media Photo, DDS, Microsoft HEIF, Microsoft Webp, Microsoft Raw Image & Microsoft Camera Raw Images.
• Includes a header file called QOIPP.h which provides MSVC C++ functions which encapsulate reading and writing QOI image files.

The enclosed zip file contains the EZView source code, precompiled binary and help documentation. The prebuilt Unicode release binary in the ReleaseU directory in the download is dynamically linked to the VC 2019 MFC DLL. If you do not have this installed then you can download it from https://visualstudio.microsoft.com/downloads/. Use the Microsoft Visual C++ Redistributable for Visual Studio 2019 (x86) download link. If you want to built the source code, then you must have VS 2017 or later installed.
