In addition, the SKCodec class has two methods named Create that can create an SKCodec object from a compressed source and allow an application to get more involved in the decoding process. The decoder can determine the file format and hand it off to the proper internal decoding function. All that's required is to supply a filename, stream, or array of bytes. The SKBitmap class contains several methods named Decode that create an SKBitmap from a compressed source. encode - compress the bitmap and write to a bitmap file format.decode - read a bitmap file format and decompress it.The compression algorithms are complex enough to warrant two terms that describe the compression and decompression processes: Fortunately, this increase in size generally only occurs for data that contains a lot of random (or seemingly random) information. Any lossless compression algorithm that reduces the size of some files must necessarily increase the size of others. Generally, JPEG is used for photographs, while PNG is used for images that have been manually or algorithmically generated.

The primary lossless compressed file format in use today is Portable Network Graphics (PNG). The original bitmap data can be restored entirely from the compressed file. In contrast, a lossless compression algorithm analyzes the image for repetition and patterns of pixels that can be encoded in a way that reduces the data but does not result in the loss of any information. Higher quality settings result in larger files. The degree of compression can be controlled with a setting generally referred to as quality. The JPEG compression algorithm analyzes the image using a mathematical tool called the discrete cosine transform, and attempts to remove data that is not crucial to preserving the image's visual fidelity. The most popular lossy format was developed by the Joint Photographic Experts Group and is called JPEG. These terms indicate whether or not the compression algorithm results in the loss of data. The two broad categories of compression techniques are called lossy and lossless.
Most of today's popular bitmap file formats use compression to reduce storage space.

You can use a model you already have or download one from the 3D Warehouse.
Open a model in Sketchup that you want to save with a transparent background. You can delete the unwanted background in Photoshop, but why give yourself an extra step? Follow these steps and you can have a transparent Sketchup PNG right from the start! Exporting a Sketchup PNG My default, if you export your current model as a 2D PNG image you will notice that the ground plane is be transparent, but the sky is not.
