Summary

Digikam is an advanced open-source digital photo management application, compatible with Linux, Windows, and MacOS platforms, that offers a wide range of features for importing, managing, editing, and sharing photos and RAW files.s.

At present, users are facing a host of difficulties when they try to transfer properties such as color, tags, and labels to numerous pictures. This is resulting in an extremely laborious and monotonous task of copying them repeatedly. This project will introduce a more advanced and efficient approach.

Timeline

Week 1-2

During this week my focus on understanding the working of images tags and how they define in images i find out key words Tags are essentially labels or keywords that people attach to pictures or images to assist in categorization and organization. Working of Images Exif understanding.

• UseFull Repo:-https://github.com/Martchus/tageditor
• Merge Rq:-https://invent.kde.org/graphics/digikam/-/merge_requests/219/diffs

None

My primary objective is to explore the process of managing tag lists for images in DigiKam. Specifically, I am focusing on understanding how to modify the code view to enable the selection of all tag lists for images with a single click. i checked out the codebase of digikam.

WHY IS IT IMPORTANT:-

None

Right now the user can check it out once taglist

• They serve as descriptive metadata, facilitating easier searching and retrieval of specific images within a collection or database. Users can manually assign tags to images, or image recognition algorithms can automatically generate tags.

Users can create a taglist or a collection of tags associated with the images by assigning Multiples tages in once Time appropriate tags to pictures. This taglists helps user in selecting multiples tages in Once Time.

• For instance, if we have a pictures Tag from a Taglist These tags can be employed to filter and add Multiples Tags in One click.

The practice of tagging pictures or creating taglists is commonly Found Diffuculty All in Once a time.

In Digikam, a powerful open-source photo management software, the tag list feature empowers us to categorize and organize our photos using tags or keywords. By assigning tags to our images, we gain the ability to effortlessly search and filter them based on specific criteria. It's important to understand how to effectively utilize multiple tags in Digikam for efficient photo management. Here's how can optimize the use of multiple tag lists in Digikam:

1. Creating Tag Lists: Start by creating different tag lists tailored to our organizational needs. For example, we can have tag lists for subjects like family, friends, or nature, as well as for locations such as vacations or cities, and even events like birthdays or weddings. To create a new tag list, simply go to the "Tags" panel in Digikam, select "Create New Tag List," provide a name, and add tags to the list.

2. Assigning Tags: When working with an image in Digikam, assign relevant tags to it. we have the flexibility to choose tags from any existing tag list or create new ones as needed. we can add tagslist by right-clicking on the image and selecting "Tags,".This action opens the tagging dialog, allowing we to select tags from different tag lists.

3. Browsing and Filtering: Once we have assigned tags to our photos, we can easily browse and filter them based on specific criteria. Within Digikam's main window, navigate to the "Tags" panel and expand the desired tag list. we will find all the tags listed within that particular list. By simply clicking on a specific tag, Digikam displays all the images associated with it. we can also perform advanced searches using multiple tags from different tag lists to narrow down our search results.

4. Tagging Hierarchy: Digikam offers the flexibility to create hierarchical tag structures, enhancing our organizational capabilities. For instance, we can establish a "Vacations" tag and create sub-tags for different travel destinations underneath it. To create a tag hierarchy, right-click on a tag, choose "Create New Tag" or "Create New Sub-Tag," and then arrange the tags within the tag list using the drag-and-drop functionality.

5. Batch Tagging: To streamline the tagging process for a large number of photos that share similar tags, Digikam provides a batch tagging feature. Simply select multiple images, right-click, choose "Tags," and assign the desired tags from any tag list. This feature saves time and ensures consistent tagging across multiple photos.

Remember, using descriptive and relevant tags is key to making our photo collection easily searchable and well-organized. By leveraging the power of multiple tag lists in Digikam, we can efficiently manage and retrieve our images based on various criteria, creating a personalized and customized photo management experience.

Week 3-4

During the course of this week, my primary objective is to incorporate the functionality of copying and pasting tags within the context of the Digikam application software. In order to achieve this, I have been working within the Digikam context helper menu, ensuring the availability of all the necessary data. The focal point of my efforts lies in the modification of this particular section by introducing a copy feature, which will enable users to duplicate and subsequently paste metadata tags according to their respective labels.

The fundamental purpose behind this endeavor is to furnish Digikam users with a copy-and-paste option, thereby affording them the capability to effortlessly replicate metadata tags. A significant portion of the work pertaining to this objective has already been completed, and my subsequent aim is to seamlessly continue this endeavor, thereby further enhancing its implementation. In order to achieve optimal results, I seek the guidance of experienced mentors who can provide valuable insights on how to improve and refine this feature.

As per the prescribed instructions, I intend to incorporate a copy menu and a paste menu, specifically designed to handle the duplication and subsequent transfer of metadata. Additionally, I have dedicated considerable time in the past two weeks to familiarize myself with the fundamental aspects of Digikam, enabling me to leverage its properties effectively. I am particularly interested in exploring possibilities for enhancing its functionality by incorporating new menu options.

To facilitate the realization of this goal, I have submitted a merge request to initiate the implementation process. It is my firm belief that this comprehensive approach will enable the seamless integration of the desired features, with a specific focus on metadata information related to various elements, such as tags, ratings, color labels, pick labels, titles, comments, and GPS information. Consequently, the selected metadata will be successfully copied from the source ItemInfo and propagated to all designated target ItemInfo entities.
