12/28/2023 0 Comments Exif to jpg converterIf you wish to generate thumbnails from other image formats such as BMP & PNG, please refer to the Resizing Images. The code snippet provided below demonstrates how to use it. NET 2.3.1, the JpegImage class contains the ExifData.Thumbnail property that can retrieve the thumbnail information from a JPEG image file. In such cases, Aspose.Imaging API retrieves the embedded thumbnail image and allows you to store it separately on disk. Some image files (especially the ones shot with a digital camera) have a thumbnail image embedded in the file. Thumbnails are reduced-size versions of pictures, used to display a significant part of the picture instead of the full frame. Sample code to demonstrate the usage is as follow: Creating Thumbnails from JPEG Images Then one can access properties exposed by ExifData class to set them accordingly. Both processes (Writing & Modifying) requires loading of an image and getting the EXIF data into an instance of ExifData class. Using Aspose.Imaging APIs, developers can write new EXIF information and modify existing EXIF data of an image. Fetch the required information and write it to console.Īlternatively, developers may also get the specific information using the following code snippet.Create and initialize an instance of ExifData class.Load an image into an instance of Image using the factory method Load.Below provided steps illustrate the usage of ExifData class to read the EXIF information from an image. Reading EXIF DataĪspose.Imaging APIs provide means to read EXIF data from a given image. Aspose.Imaging has provided ExifData class for reading, writing and modifying the EXIF data, where as namespace contains the relevant enumerations used in the process. Developers may also write EXIF data to the images or modify the existing information as per their requirement. Aspose.Imaging APIs has made possible to extract the EXIF information from a given image in a very easy and simple manner. EXIF data also include shutter speed, date and time a photo was taken, focal length, exposure compensation, metering pattern and if a flash was used. Camera settings and scene information are recorded by the camera into the image file.
