  2. Transfer printing - Wikipedia

    en.wikipedia.org/wiki/Transfer_printing

    Printing on enamel probably began around 1753 (a letter of Horace Walpole dated 7 September 1755 mentions a printed Battersea box), and by around 1756 his process was being used on some Bow porcelain, although the results were not excellent, perhaps as the glaze was "too soft and fusible", giving a tendency to blur the image. The colours of the ...

    JPXDecode, a lossy or lossless filter based on the JPEG 2000 standard, introduced in PDF 1.5. Normally all image content in a PDF is embedded in the file. But PDF allows image data to be stored in external files by the use of external streams or Alternate Images. Standardized subsets of PDF, including PDF/A and PDF/X, prohibit these features.

  4. Image compression - Wikipedia

    en.wikipedia.org/wiki/Image_compression

    Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission. Algorithms may take advantage of visual perception and the statistical properties of image data to provide superior results compared with generic data compression methods which are used for other digital data.

  5. Chifir - Wikipedia

    en.wikipedia.org/wiki/Chifir

    Preparation of chifir in an enamel mug. Chifir (Russian: чифи́рь, romanized: čifir', or alternatively, чифи́р (čifir) is an exceptionally strong tea, associated with and brewed in Soviet and post-Soviet detention facilities such as gulags and prisons. Some sources mention properties of a light drug, causing addiction.

  6. ICER (file format) - Wikipedia

    en.wikipedia.org/wiki/ICER_(file_format)

    JPEG 2000 implements a low complexity symmetrical wavelet lossless compressor, but ICER uses an integer only non-wavelet lossless compressor. ICER and JPEG 2000 encode color spaces differently. ICER in its current form does compress monochrome images better than colour images due to its origins as an internal NASA Deep Space Network file format.

  7. Data compression - Wikipedia

    en.wikipedia.org/wiki/Data_compression

    Composite image showing JPG and PNG image compression. Left side of the image is from a JPEG image, showing lossy artefacts; the right side is from a PNG image. In the late 1980s, digital images became more common, and standards for lossless image compression emerged. In the early 1990s, lossy compression methods began to be widely used. [14]

  8. S3 Texture Compression - Wikipedia

    en.wikipedia.org/wiki/S3_Texture_Compression

    S3TC is a lossy compression algorithm, resulting in image quality degradation, an effect which is minimized by the ability to increase texture resolutions while maintaining the same memory requirements. Hand-drawn cartoon-like images do not compress well, nor do normal map data, both of which usually generate artifacts.

  9. Vitreous enamel - Wikipedia

    en.wikipedia.org/wiki/Vitreous_enamel

    Vitreous enamel, also called porcelain enamel, is a material made by fusing powdered glass to a substrate by firing, usually between 750 and 850 °C (1,380 and 1,560 °F). The powder melts, flows, and then hardens to a smooth, durable vitreous coating.
