Adding support for quality AutoCAD (DWG/DXF) thumbnails

Daminion can import AutoCAD DWG and DXF files, but it’s hard to find the right drawing visually because the preview of these files is a default icon rather than a quality thumbnail.

However, if you download and install the free DWG TrueView from the AutoDesk you will be able to view quality thumbnails your AutoCAD DWG and DXF files, not only in Windows Explorer but also in Daminion.

AutoCAD thumbnails that still appearing as default icons can be rebuilt in the following way from the Daminion menu: Item > Rebuild Thumbnail (Ctrl + B)

Adding support for quality Cineform Video thumbnails

To display thumbnails of videos encoded with the Cineform codec in the Daminion please do the following:

For Local Catalogs

1. Download this zip file
2. Unpack it and copy the CFDecode2.ax and RegCineForm.bat files into the following folder:
c:\Program Files (x86)\Daminion Software\Daminion\MediaProcessors\VideoProcessor\codecs\
for your Daminion Standalone version.
3. Run the RegCineForm.bat as the Administrator

For Shared Catalogs

1. Download this zip file
2. Unpack it and copy the CFDecode2.ax and RegCineForm.bat files into the following folder:
c:\Program Files (x86)\Daminion Software\Daminion Server\MediaProcessors\VideoProcessor\mplayer\codecs
on the PC where the Daminion Server is installed.
3. Run the RegCineForm.bat as the Administrator

Now all newly imported Cineform video files will be displayed with quality thumbnails. To update the thumbnails of already imported Cineform files with the default video icon, select these videos in the Daminion and press Ctrl + B.

Accelerating preview of large images

Huge images in Camera RAW, TIFF, PSD and BMP formats are now cached as JPEG previews and can be viewed at the same speed as regular JPEG images. This is especially noticeable when images are very large (more than 300 MB) or located on networks with lower bandwidth connections.

This option is turned on by default but can be switched off via program Preferences. When this feature is enabled, thumbnail generation and import speed will be slower, but the previewing of large images will be much faster and it will also reduce CPU load of the Server PC .

To change this option, do the following:

For Local catalogs:

  • Launch your Daminion Standalone version
  • Go to the main menu: Edit > Preferences
  • Switch to the Accelerate Preview option

For Server catalogs:

  • Launch the Daminion Server Administration panel on your server PC
  • Go to the main menu: Administration > Preferences
  • Switch to the “Accelerate Preview” option

If the “Accelerated preview of large images” option is checked, Daminion will also store full-size JPEG previews of large images when rebuilding thumbnails.

You can limit the maximum size of JPEG images by turning on the “Limit maximal JPEG preview size” option. For example, with 100 Megapixels limit your JPEG previews can have maximal sizes of 10000×10000, or 20000x5000pх, etc…


 

Which media formats does this option works for?

It works for Camera RAW, PSD, TIFF and BMP formats only.

Where will my JPEG previews be stored?

For local catalogs:  in the ~Thumbs\preview folder in the same folder as your local .dmc catalog.

For shared catalogs: in the “preview” sub-folder of the folder that was selected to store the thumbnails from your server catalog. This can be checked or configured via the Daminion Server Administration panel individually for each catalog.

 

Thumbnail Grouping

In your browser, you can combine thumbnail previews in groups. So you can, for example, summarize a series of images consisting of many similar designs as one thumbnail.

 

Grouping Thumbnails

First, select at least two thumbnail preview images in the Browser. Now you have three ways to take the images in a group.

 

Option-1

Click with the right mouse button on one of the thumbnails. It opens a context menu as shown in Figure below.

Grouping thumbnails with the context menu

(click to enlarge)

 

Click on “Grouping” and then on “Group“. So you take all selected images together in a group. Depending on which of the pictures you run the command, this is used as a displayed thumbnail preview image for the whole group.

 

Option-2

If you have selected the images, and then move the mouse to the upper right corner of the thumbnail previews, a small clickable icon “Group Selected Items” appears.

Depending on which of the pictures you run the command, this is used as a displayed thumbnail preview image for the whole group.

 

Option-3

After you have selected the images, press the key combination [Ctrl + G] to unite the images in a group.

Diaplay of image count in a groupAll four images are now grouped together, the total number of the combined images is shown in the top right corner of the thumbnail.

 

 

 

 

 

 

 

Collapse and expand a group

Expand and collapse a groupe with the mouse buttonMove the cursor back to the upper right corner of the thumbnail preview, where normally the number of grouped images is displayed. As you hover the mouse over it, the display changes to a direction indicator icon. By clicking on it you can quickly expand and collapse the grouped images.

Alternatively, you can also use the keyboard shortcut [Ctrl + D].

 

 

 

 

Ungrouping

Click with the right mouse button on a group of pictures and choose “Group” – “Ungroup“>. Alternatively, you can also use the keyboard shortcut [Ctrl + Shift + G].

Ungroup a Group with the context menu

The group is now disbanded.

 

 

Splitting a group

You can also split an existing group into several groups.

Expand the appropriate group,click with the right mouse button on the image, from which a new group to be created, and then on “Group” -> “Split Group“.

In this way you can quickly split one large group into smaller groups.

 

 

Choose a display picture for the group

You can choose which thumbnail is to be used as the main preview of group images for display.

Expand the group and click the right mouse button on the image to be displayed and select “Grouping” -> “Move to Top of Group“.

 

 

Remove images from the group

Expand the appropriate group and click the right mouse button on the image that you want to remove from the group and choose “Group” -> “Move Out from Group“.

 

Compare Items

Compare Items view allows you to quickly find the right image from a series of similar images. You can exclude, select and/or rate images. And you can zoom all images simultaneoulsy with just one click – useful for quickly identifying the sharpest image in a series.

 

Launching Compare Items View

Select the photos you want to compare (from 2 to 8 images at a time).

In the file menu, navigate to “Item” and then click “Compare Items“.

Click the Make Master button to anchor the respective image in the top left corner of the first window. The image can only be replaced by clicking Make Master above another image in the film strip.  

 Use this button to reject an image and hide it from the display. Once rejected, the image is replaced by the next one in overall selection. In addition, a red ‘no’ symbol marks the image in the filmstrip. 

 Rate your images here.

 Flagging – described in  Flagging an Item.

 Use the Close button to close the respective sub-windows. Doing this allows you to eliminate unsuitable images one at a time until you are left with two best images. 

 

The filmstrip at the bottom of the screen displays all images currently present in browser window.

In addition, the images currently displayed in the viewports above are marked respectively in the filmstrip. The “M” stands for Master (your choosen candidate) and the numbers #1#8 are the respective candidates currently on display in the viewport.

The currently selected image is displayed in the viewport within a white frame. You can replace this image, either by rotating the mouse wheel or by clicking on another image in the filmstrip.

 

 

Zoom View

Hold the mouse pointer over any one image and click to view all images at 100% magnification. Then use the mouse pointer to move all images simultaneously to help you identify the most appropriate candidate.

Information below thumbnails

Here you will see the list of the tags currently displayed below the thumbnail.

 

Add

With the “Add” button you can add more tags from a list to display below the thumbnail.

 

Delete

Use the “Delete” button to remove tags that should no longer be displayed.

 

Sorting

With the up and down arrow buttons you can set the sort order of the tags.

 

Once you have made your selection  close the dialog with the “OK” button. The thumbnails will be displayed in the browser according to your new settings

Adding Custom Thumbnails

Assigning custom thumbnails to unknown file formats in Daminion.

Daminion shows thumbnail previews of all imported files. For image files, the preview is a bitmap of the image; for video files it’s the first frame of the video sequence.

Unbenannt-5_ENG

Unknown file formats added manually to Daminion’s import list are shown as a default preview (like the “unknown” manually-added VOB video file in the screenshoot to the left).

 

 

 

 

Daminion allows you to change this default preview to a more meaningful image of your own choice.

In order to import and manage these files, you must first add the unknown format to Daminion’s list of imported filters, as described in the chapter Adding an unknown file format.

A standard preview thumbnail is displayed for manually added file formats, either because Daminion does not know the structure of the particular file format and is therefore unable to read the embedded preview, or because this type of file doesn’t generally contain a preview image.

In order to display a meaningful preview, the imported file must be accompanied by a specially named jpeg file.

Let’s say you have a VOB video file, and you want Daminion to display it with your own thumbnail. First of all, select a jpeg image for Daminion to use as the thumbnail preview.

In our example, we chose a jpeg file, ferris_wheel.jpg, whose name and image are closely associated with the video content. The jpeg and the video file must be stored in the same folder.

For Daminion to use your jpeg file instead of the default preview, you must rename the jpeg in the following way:

filename.ext.thumb.jpg

 

Replace the first part, filename.ext, with the name of the video file. In our case, this gives us footage.vob.thumb.jpg

 

Now, when you import this video file, Daminion automatically looks in the source folder for a jpeg file that fits this naming convention. If such a file exists, it is automatically used as the preview thumbnail for this imported video file.

You can also use this method to create custom thumbnail previews for files you have already imported. To do this, choose a suitable jpeg, place it in the same folder as the file you’d like it to represent and follow the renaming procedure as explained above. Now, select the file to be linked to the jpeg thumbnail and press Ctrl + B. Daminion will update the preview for this file and incorporate the new custom thumbnail.
