JPEGView Portable 1.0.27 is a small and fast viewer/editor for JPEG, BMP, PNG, GIF and TIFF images. On-the-fly image processing is provided - allowing to adjust typical parameters as sharpness, color balance, contrast and local under-/overexposure. It's packaged in PortableApps.com Format so it can easily integrate with the PortableApps.com Suite. It supports upgrades by installing right over an existing copy, preserving all settings. And it's open source and completely free

JPEGView provides an unobtrusive interface to image viewing with most controls only appearing on mouse-over of the window or the lower section of the window (for image processing controls). It has a simple black-background and an optional full-screen mode enabling you to really look your images without

What's New in This Release:
Replaced Intel JPEG library by Turbo JPEG (tjpeg, http://sourceforge.net/projects/libjpeg-turbo/)
This replacement has many reasons:
- The Intel library license was not an open source type license
- Newer versions of the Intel library are not free of charge. The old versions are not supported by Intel anymore.
- Some JPEG files could not be read by the Intel library. tjpeg can read these files.
- There is no free 64 bit version of the Intel library.
(This is important for the future when there may be a 64 bit version of JPEGView)
The tjpeg library is open source and (at least on modern CPUs) performs comparable to the Intel library. It is used by many other
viewers and several Linux distributions.
Note that tjpeg including lossless JPEG transformations has been statically linked to JPEGView. Therefore the application has grown
by 300 KB. However the total size of the package is lower than before because IJL15.dll and jpegtran.exe are no longer needed.
Bugs fixed:
- When a folder is called 'pictures.jpg' for example, JPEGView no longer tries to process this folder as image
- Exposure time display: When nominator and denominator are both big numbers, a fractional value is shown instead of bigNum/bigDenum
- Reading slideshow list files (txt) encoded with UTF-8 and UTF-16 (little endian only) correctly
- Reading slideshow list files (txt) using uppercase file endings for image files correctly
New features:
- Lossless JPEG transformations integrated into JPEGView. The jpegtran.exe application is no longer part of the distribution of JPEGView.
- Basque translation, thanks to Xabier Aramendi
- Chinese translation, thanks to Yia Guo
- Keymap.txt now also supports to remap mouse buttons to commands.
- New INI file setting: 'TrimWithoutPromptLosslessJPEG'. Set to true to trim image before lossless JPEG transformations if needed without prompting the user for each image.
- New INI file setting: DefaultWindowRect=sticky to save and restore the window size and position in window mode
- New INI file setting: 'SingleInstance'. Set to true to open all images in one single instance (window) of JPEGView.
- New INI file setting: 'ShowBottomPanel'. Set to false to disable showing the bottom panel when hovering with the mouse on bottom part of window/screen.
Default is true (as before, was not configurable).
- New INI file setting: 'MaxSlideShowFileListSizeKB'. Sets maximum size of slide show text files in KB.
- New INI file setting: 'ForceGDIPlus'. If true, use GDI+ for reading JPEGS. Note that using GDI+ is much slower than the tjpeg library!
- New command line parameters:
/slideshow xx Starts JPEGView in slideshow mode, xx denotes the switching time in seconds. Only use when providing a file name,
folder name or file list on the command line as first parameter.
Example: jpegview.exe "filelist.txt" /slideshow 2
/fullscreen Starts JPEGView in full screen mode, ignoring the INI file setting that is currently active
/order x Forces file ordering mode 'x', ignoring the INI file setting that is currently active
'x' can be M, C, N or Z, for the file ordering modes 'M:modification date', 'C:creation date', 'N:file name', 'Z:random'
Example: jpegview.exe c:\pictures /slideshow 2 /order z
Shows a slideshow of the files in the folder "c:\pictures" using random ordering and an interval of 2 seconds.
Other changes:
- Because the tjpeg static library cannot be linked with VS2005, JPEGView is now compiled with VS2010. If you are using Windows XP
before SP2, install SP2 or keep using version 1.0.26.
