- Display Method
ExifPro can display photographs without jagged details when using ‘Smooth drawing’ option.
This smoothing is CPU-intensive, so it affects redrawing speed. For slower machines one can switch
to ‘Fast drawing’. It offers lower display quality (using point sampling), but is considerably faster.
ExifPro uses thumbnail images extensively to show small images, calculate histograms, compare images by similarity.
It can either use existing thumbnails embedded in photographs or regenerate them. Due to the low quality of embedded
thumbnails it is recommended to generate them from original photographs. Once generated they
will be stored in a cache file. The only downside of generating them is slow first-time scanning. Subsequent visits
to the same folder will use cached information.
Thumbnails option has three settings: ‘Generate when not found in a cache’ will always regenerate thumbnails
if they haven't yet been stored in a cache file. ‘Skip generation when reading from a removable drive’ is
similar to the first one, except that images read from removable drives (like CompactFlash cards via USB readers) will
NOT be used to generate thumbnails. Finally third option ‘Do not generate thumbnails, use existing ones’
will not attempt to generate thumbnails at all (unless embedded ones are missing). It is also the fastest one during
initial folder scan.
It is advisable to turn thumbnail generation on to obtain much better appearance of thumbnails, more accurate histograms
in a histogram pane and more reliable sorting by similarity.
- JPEG Decoder
Alternative JPEG decoder implementations offer different quality/speed of opening JPEG images. High quality
implementation is marginally slower than fast method.
- Memory Cache Size
ExifPro maintains cache of thumbnail images and preview images to speed up redrawing. Size is specified as a
percentage of physical RAM size. At least 10 MB of RAM is recommended to be assigned for a cache.
Note: this is memory used for thumbnails and preview images only; apart from this ExifPro will need RAM to
display images in a Viewer window as well as to store a list of photographs.
- Optimize Thumbnail Access
While scanning JPEG images ExifPro may retain compressed thumbnail images in memory to speed up redrawing. This
option (‘Decoding speed’) consumes considerable amount of memory per image, and is best suited to small
collections of images (up to a few thousands of images loaded at a time).
For large collections of images or
computers with limited RAM ‘Minimal memory usage’ option is useful. Redrawing speed will be considerably slower
(especially while scanning is still in progress), but memory used per image will be drastically reduced. This allows
for loading tens of thousands of images (it is recommended to increase cache file size limit to 4 GB in such case).
- Preload next/previous photo
Image viewer may load photograph in advance to speed up browsing. Warning: it may be memory intensive.
- ‘Best Fit’ may magnify small images above 100% of their size
Small images may be magnified (stretched) to the full available space if this option is checked. This happens in
both viewer window and preview pane. If you prefer ‘Best Fit’ to leave small images at 1:1 zoom level
uncheck this option.
- Save applied tags in photographs
Tags toggled in the Tag Bar window may be saved inside JPEG files. If not checked tags
are only maintained for the current ExifPro session and will be lost after exit.
- Show warning when broken thumbnail image is encountered
EXIF block usually contains little preview image. ExifPro may show warning message if this image is corrupted.
- Close ExifPro when exiting Viewer started from command line with an image path
ExifPro may be associated with certain file extensions in a Windows Explorer (say JPG extension). When clicking on such images ExifPro viewer window will be opened. This option tells ExifPro whether it shall exit when the user closes viewer window or switch back to the main window.
- Image Fading in a Viewer Window
When showing next image in a viewer window smooth transition will be applied (fading) if selection here is set to
‘always’. It may also be limited to the slide show mode or turned off completely.
- Image Cache File
ExifPro will store extracted EXIF block, thumbnail image along with other data inside the cache file to speed up
rescanning folders. Drag the slider to limit size of this file. Press ‘Clear’ to delete cache files
(they will be recreated from scratch next time reloading starts).
Typical cache file location: SystemDrive:\Documents and Settings\All Users\Application Data\MiK\ExifPro\CacheDb*.*
