Generate Thumbnail from JPEG & Export Specific Layout in DXF Drawing to PDF

What’s new in this release?

We are pleased to announce the new release of Aspose.Imaging for .NET 2.3.0.  A thumbnail is a small copy of an image mostly used for recognition purposes when more images are stored in a library. Usually, when the image is shot with a digital camera, the thumbnail information is stored in the image metadata and can be retrieved through imaging libraries such as Aspose.Imaging for .NET API. With this release, Aspose.Imaging has provided a convenient mechanism to extract the thumbnail information from the image metadata. Aspose.Imaging now provides the long awaited feature of image cropping for the RasterImage class by introducing the Crop method. There are two overload versions of the Crop method available based on two different approaches as discussed below,

• Shift Mode: One of the overloads accepts 4 integer parameters denotes as Left, Right, Top and Bottom. Based on these values, the Crop method shrinks the image boundaries toward the center of the image while discarding everything outside the boundaries.
• Rectangle Mode: As the name suggests, this mechanism can be used to highlight a particular area by cutting it out of the image. The area should be defined using an instance of the Rectangle class and passed to the other overload of the Crop method.

Prior to Aspose.Imaging for .NET 2.3, the API facilitated exporting a specific layer of the AutoCAD DXF drawing to PDF format. With this release Aspose.Imaging adds another exciting feature that allows you to select a layout from a DXF drawing, and export it to PDF. The main new and improved features added in this release are listed below

• Add support for invisible objects
• Expose Jpeg features
• Add support for text rotation angle for dimension objects
• Request for Image Cropping Facility
• Publish PdfOptions.Layout property
• Dual sign the .Net assembly

• ImageLoadException: Malformed exif section at Image.Load
• Dithering algorithm sometimes produces animated gif-s with blinks due to wrong transparent color processing.
• Improve rendering of text entity
• JPG to TIFF conversion results in poor image quality.
