+In 2.0.2 (we just noticed that we are now the half of not found :)
+a new feature was introduced which is very useful for us
+and we think it may be useful for those of you who also work in the computer vision field.
+We are now able to load the .vec file of the OpenCV Cascade Classifier.
+So you can easily control if the patches you trained,
+or the patches [OpenCV](https://opencv.org/) created automatically are correct.
+Of course we have not added the .vec extension to the default settings of nomacs, because there exists a lot of other vec files.
+Thus, you have to add the extension to nomacs manually.
+You can do this by opening the “File” -> “Add Image Format”  dialog.
+Then you can drag&drop your file into the dialog or use the browse to the file.
+
+![add-formats](add-formats.png)
+
+After clicking add you have to name the new file format.
+After that you can open your .vec files with nomacs.
+
+<img alt="img-2014-07-31 09.22.22" src="img-2014-07-31-09.22.22.png" width="100%">
+
+Due to some limitations of the fileformat nomacs assumes that the patches are square
+and thus if you open a file containing non-square nomacs is unable to load it.
+If you want to use non-square patches you have to specify the size in the file name.
+You can do this by adding “-w\[width\]-h\[height\]”.
+So for example you have to name your file “samples-w35-h25.vec”.
+Have fun with this feature and may it simplify your training step

+
+Since the last release we are getting more and more requests if we can support different file formats.
+Apparently it turned out, that we already support most of them but we have not added the file extension to our file filter.
+This is especially true for RAW formats of image files,
+we just simple don’t know all extensions of all manufacturers and we don’t have sample images from all of them for testing.
+
+But there is a simple solution: you can easily try to add new files formats to nomacs.
+You just have to use File -> Add Image Format
+– this opens a dialog where you can drop (or load) your images and nomacs will tell you if the file extension is supported.
+If it is supported it will display the image.
+After adding the file format you can use our File Filter settings in the preferences dialog
+to set nomacs as default viewer for these images.
+If you have successfully added a new file format,
+please drop us a note in our bug tracker and we will add the extension to nomacs.
+If nomacs is unable to load you file format, please add a new feature request.
+If possible attach also the image to the request so we can test it easily.
+
+Open the “Add Image Format” Dialog
+
+<img alt="Open the “Add Image Format” Dialog" src="add-file-format.png" width="100%"/>

+
+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.
+<img src="batch-processing-005-annotated1.png" alt="batch-processing-005-annotated1" width="100%"/>
+
+## Copy/Rename
+
+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.

+
+## Image Conversion
+
+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.
+<figure>
+  <img alt="batch convert images" src="batch-convert.png" width="100%"/>
+  <figcaption><em>batch convert images</em></figcaption>
+</figure>
+
+## Resize/Transform
+
+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.
+<figure>
+  <img alt="batch resize" src="batch-processing-009.png" width="100%"/>
+  <figcaption><em>batch resize</em></figcaption>
+</figure>
+
+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°.
+<figure>
+  <img alt="batch transform" src="batch-processing-012.png" width="100%"/>
+  <figcaption><em>batch transform</em></figcaption>
+</figure>
+
+## Processing
+
+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.
+<figure>
+  <img alt="processing images" src="batch-processing-003.png" width="100%"/>
+  <figcaption><em>processing images</em></figcaption>
+</figure>
+
+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.

+Since nomacs 3, you can change the background image which is displayed on start-up.
+You just need to place an image called ‘bg.png’ into a folder together with your nomacs.exe.
+Here is how this looks like:

+If you add a second file named ‘bgf.png’, the splash screen of the frameless mode will be overwritten.

+But the most important improvement is the key selection.
+Up to now you were only able to select pre-defined exif keys.

+If you click Change Entries, this dialog will appear:

+The dialog lists all exif entries of the currently loaded image.

+
+in nomacs 3.10.2 we have added a better multi user support because of your feedback.
+
+Basically you can now create default settings that are applied to all user settings after the first start-up.
+Therefore, you have to export your desired defaults by `Edit > Settings > General > Export Settings` and name them `default.ini`.
+If you now replace the default.ini in the nomacs install directory,
+these settings will be applied if a new user starts nomacs for the first time.
+
+– the nomacs team
+
+HINT: the check for updates option is an issue for some large companies. Creating a default.ini with this content:
+
+```ini
+[SynchronizeSettings]
+checkForUpdates=false
+disableUpdateInteraction=true
+```
+
+will disable checking for updates. Additionally, users won’t be able to manually check for updates anymore.
