we had a lot of time for coding in winter – so here is a new nomacs with the beginning of spring. We manly reworked the image adjustments and added a few such as exposure correction. Here is the complete changelog:
– Image adjustments introduced
– Exposure added
– Improved profiles
– Image adjustments added
– Settings for batch plugins
– Extended tab functions (thanks to @cornytrace)
– Settings Editor
– Icons for high DPI displays
– Crash on exit fixed for Linux with Qt 5.7.1
– Updates (Windows)
– Qt 5.5.1 -> 5.7.0
– OpenCV 3.1 -> 3.2
[EDIT] we hat to draft a Hotfix for translations were not loaded properly in nomacs 3.6.0. So if you already updated to 3.6 please update again to 3.6.1
following the successful Google Summer of Code participations in 2012 – 2014 together with the CSE @ TU Wien we are accepted again in 2016. If you are interested in earning money while developing at an Open Source project… this is your chance! You can find more details on how to apply here.
A good friend of us recently developed a zombify app named Zelfie. Check it out if you have an Android device and want to get some post-halloween feelings here. He also developed the pseudo color bar for nomacs.
nomacs 3 will be released with a brand new & shiny installer. Therefore and for other reasons we will leave sourceforge. To guarantee fast downloads, we will rent a webspace which costs around 50€ (~56.085$).
Now we face two options:
Google AdSense which adds ads to this webpage resulting in an ugly page
If you donate 50€ until the end of 2015, this page keeps its simple white UI and no ads are added until the end of 2016. There are three ways how to keep an ad-free interface:
a rich contributor donates 50€
every 100th download 2€ are donated
every 100th visitor donates 50 cents
be part of it:
thank you — the nomacs team
[UPDATE]: we have reached our goal of 50€ – thanks to all donators! As promised, nomacs.org will remain free from ads and nomacs 3.0 will be hosted on a new server which drastically improves the update process.
Of course we will still appreciate any donations (we are far from being a big corp : )
We have upgraded the Metadata HUD panel. At a first glance it looks pretty much as in previous versions.
If you right click the panel, there will be a few new options:
Similar to the Thumbnail preview, you can choose where to display the panel. If the panel is in Horizontal Layout (Top or Bottom) you can choose the number of columns. If the data does not fit to the current window size, a scroll bar will appear.
But the most important improvement is the key selection. Up to now you were only able to select pre-defined exif keys. Since exif values are pretty dynamic, you can now choose an image which has special entries. If you click Change Entries, this dialog will appear:
The dialog lists all exif entries of the currently loaded image. Checking an entry there will add the entry to the metadata HUD.
nomacs supports batch processing since version 2.4. You can open the bach processing from the Menu > Tools > Batch Processing. Currently there are four different processing modes (Copy/Rename | Image Format Conversion | Image Resize | Transforming).
First you can choose the directory and select the files you want to process. File selection is similar to the thumbnail preview (select multiple files using CTRL, hold SHIFT to select files consecutively or hit CTRL+A to select all files of a folder). You can additionally filter a subset using search terms or regular expressions (in the example below all files are chosen which start with a lower case character). After selecting the files to be processed you can click the Icon Add Files to the File List. If you open the File List Tab, you can also drop multiple folders to select their files for processing. Having selected the files to be processed, you can choose an output directory. The output panel allows you to choose the old filename or rename all processed files. The screenshot shows a file conversion where 87 files are converted to png.
The Output panel allows you to choose an output directory and rename/convert files. You can choose a custom filename. Do not forget to add a sequence number such that the filenames are still unique. The filename preview picks a selected image and shows the old and the new filename accordingly. If input and output directory are the same, images will be renamed in place. Otherwise the images are copied and renamed. This action will not change the image encoding.
If you want to convert images to a specific output format (e.g. PNG) you can change the Keep Extension drop down to Convert To. Then select your preferred format. You can choose any format which is supported by nomacs.
Click the + next to Resize/Transform to apply an image transform. If you e.g. want to downsample all images of a folder, you can choose Long Side in the resize panel. Then enter the desired side length in pixel. This option will resize the image such that the width of panorama images or the height of portrait images will be set to the desired pixel length. If you check Shrink Only images which have a lower long side than the desired length will not be resized.
The Transform panel allows you to rotate or flip all images. The gray text next to the panel title indicates if a panel is active or not. The example below shows a configuration which resizes all images by 50% and then rotates them by 180°.
After you configured the batch processing according to your needs you can hit OK. A progress bar will appear which indicates the percentage of images already processed. If you notice a wrong configuration, you can cancel the processing. All images processed will stay the same then but the processing is stopped immediately.
All processing actions are logged. Choose Show Log to see the status of the processing. You can see the status of every batch module and check if it was processed successfully. Please check the batch configuration before Processing especially if you check Overwrite Existing files since these actions cannot be reverted.
The Overview Panel (Menu > Panels > Overview) enhances zoom and pan. The blue rectangle shows the current viewing area. You can pan to a specific location by dragging this rectangle to the desired position. The scrollbar at the bottom allows you to zoom. If you want to zoom to a desired factor (e.g. 600 %) you can mark and replace the text accordingly.
