Communicating ideas in digital documents can often be made much clearer through the use of layers. Layers have been supported in PDF documents since version 1.5 through optional content groups (OCGs), also known as PDF layers. “Optional” is key here. OCGs allow us to group images or annotations together, then control their visibility based on […]

Hi Everyone, We’re now back from CES where we presented our new PassportPDF solution to the public. We’re a bit late for this wrap-up, but what happened is that all of us who went to Vegas caught the flu on the way back (thank you, freezing planes and convention center!), which slowed things quite a […]
Previously in the PDf Optimization In-depth Series. Resizing images Resizing images can provide significant gains in occupancy. For example, decreasing unnecessary high resolutions can dramatically reduce the file size without affecting the viewing experience. But sometimes it is also a pretty destructive approach. There exist many sophisticated resizing algorithms, but it is rare to obtain […]
Previously in our PDF Optimization In-depth Series: MRC compression in PDF documents is highly efficient in file size reduction without visible degradation of document rendering. MRC, also known as hyper-compression, is an image compression benefiting from image segmentation methods. It is particularly useful for images containing text and continuous-tone graphics. This method reduces the size […]
Previously published in the PDf Optimization In-depth Series: Sometimes, when acceptable or necessary, it may be interesting to recompress images already included in an existing PDF file to reduce the file size. The PDF specification allows for seven compression schemes for such purposes. All of them can be used to compress images. Among these different […]
