4 viewer windows stitched together

nomacs is a free image viewer for windows, linux, and mac systems, which is licensed under the GNU General Public License v3. nomacs is small, fast and able to handle the most common image formats including RAW images. Additionally it is possible to synchronize multiple viewers. A synchronization of viewers running on the same computer or via LAN is possible. It allows to compare images and spot the differences (e.g. schemes of architects to show the progress).

nomacs 1.0.2

April 5, 2013 : 11:30

about 40 years and 2 days after Martin Cooper (@MartyMobile) did the first mobile telephone call, the first bugfix-only nomacs is released. the bugfixes include:

  • Support for DNG format
  • Zoom/Pan is faster for Mac OS
  • EXIF data can be read for UTF-8 files (Windows only)
  • Open With starts custom executables again
  • Drag&Drop works directly after installing (no administrator privilegs)
  • dpi is now saved when changing it in the resize dialog
  • resize dialog does not crash for 40k x 30k images
  • translations updated & serbian translation added

NOTE:

for the automatic update routine will download the wrong version for Windows XP (this is already fixed in the 1.0.2 version – so it is the last time you need to manually install nomacs : )

Why webP

March 1, 2013 : 16:27

according to a feature request from dadatamada we took a closer look to the webP format. the screenshot shows a nightly build of nomacs with webP load/save functionality. if an image needs to be compressed, webP shows a far better image quality while decreasing the file size. note that the jpg compressed image (right) has 16.6 KB while the webP image only needs 6.8 KB. another advantage is the fact that webP features a full (8bit) alpha channel and supports lossless compression…why webp
