In many cases, after the reverse filtering process is complete the data is ready to display If an application has the required information, the decoder can color correct the pixel data If the PNG file contains a HRM chunk, the decoder can convert the pixel data to CIE 1931 format to get the exact colors shown on the source display, then correct the data for the destination display If the file contains a gAMA chunk, the data can be Gamma corrected for the output display 16- to 8-bit Conversion Most current computer systems only support bit depths of up to 8 Unless you are writing a decoder for a specialized system that supports greater bit depths, you are going to have to convert 16-bit data values to 8 bits The technically correct method to convert pixel values from one bit depth to another is Equation 141 Bit Depth Conversion New Value = Old Value The easiest method to convert from 16 to 8 bits is to discard the low-order byte of each 16-bit color value after applying color correction (if applicable) The results are virtually indistinguishable from that of Equation 141 Either of these two methods could create large, solid blocks of colors that could look odd, especially in photographs In some situations you may wish to apply dithering during the color conversion Transparency If the color type is RGB with Alpha or grayscale with Alpha, or if the PNG file contains a tRNS chunk, transparency can be applied if desired If the image is being drawn on a background and the decoder has access to the background's color data, the image in the PNG file can be combined with the background pixels using the process described in the previous chapter Another possibility is to combine the image with a solid background that is specified by the application or from a bKGD chunk. winforms code 39 reader Packages matching DataMatrix - NuGet Gallery
