Gahaku overview

Gahaku is an image viewer for professionals running on OS X. Gahaku can display pixel values of an image in various color spaces, i.e., RGBA, HSL, HSB, Y'PbPr, linear RGB, XYZ, xyY, Lab and Luv. It can also provide histogram, waveform, and vectorscope panels which help you to investigate comprehensive image information.

Gahaku is a simple and fast image viewer, which can support those who analyze images both in technically and scientifically, especially for engineers, researchers, teachers, designers, and artists.

Gahaku supports the image formats that OS X supports, including 8-bit and 16-bit image, such as, PIC, PICT, HDR, EXR, MAC, PNT, PNTG, TARGA, TGA, CUR, XBM, BMP, ICO, PSD, ORF, MRW, RWL, RAW, RW2, RAF, CRW, ICNS, EFX, JFAX, JFX, G3, FAX, TIF, TIFF, DCR, ERF, ARW, SR2, SRF, PEF, NRW, NEF, 3FR, FFF, MOS, CR2, DNG, JPF, JP2, GIF, JPE, JPEG, JPG and PNG.

You can quickly browse images with keyboard shortcuts like a popular image viewer, the IrfanView, does (just in case, Gahaku is a viewer and cannot edit images, while the IrfanView can do a lot of things.).

What’s new in version 1.2.1

Updated on Apr 18 2013

Version 1.2.1:
  • Changed multiple image handling. When multiple images are selected to open from Finder or dropped to the dock icon, Gahaku opens them in a single window instead of a separate window. Please note that if multiple images are opened from the menu of Gahaku as "Open > File", the images are opened in a separate window just as the previous version did. You can choose whichever way you want.

I am very disappointed! Always crashes opening any file !!!! I wrote at Gahaku's developer (the author uses only Google+ and does not have an email address...) but without answer... I have Mac OS x 10.7.5 Lion and iMac 20-inch Late 2006
