The devices differ, in that the pngalpha deviceĮnables Text and graphics anti-aliasing by default. Give a transparent background with this device. The png16malpha and pngalpha devices are 32-bit RGBA color with transparency Rendering which is then error diffused and converted down to 1bpp. The pngmonod device is also aīlack-and-white device, but the output is formed from an internal 8 bit grayscale Pngmono devices respectively provide 8-bit color, 4-bit color andīlack-and-white for special needs. For normal use we recommend png16m for 24-bit RGB color, Ghostscript provides a variety of devices for PNG output

It supports full qualityĬolor and transparency, offers excellent lossless compression of the image data,įor a complete description of the format. PNG (pronounced 'ping') stands for Portable Network Graphics,Īnd is the recommended format for high-quality images. These suppress interactive prompts and enable some It is also conventional to call Ghostscript with the ' -dSAFER -dBATCH -dNOPAUSE' trio Antialiasing is enabled separately for text and graphics content.īecause this feature relies upon rendering the input it is incompatible, and will generateĪn error on attempted use, with any of the vector output devices. The size of the subsamplingīox n should be 4 for optimum output, but smaller values can be used for faster Their use is highly recommendedįor producing high quality rasterizations of the input files. These options control the use of subsample antialiasing. dTextAlphaBits= n -dGraphicsAlphaBits= n The default value if you don't specify this options is usually 72 dpi. This option sets the resolution of the output file in dots per inch. ' figure-%03d.jpg' where the %03d is replaced by the page number. It can either be a single filename ' tiger.png' or a template This is a general option telling Ghostscript what to name the output.

Ghostscript supports output to a variety of image file formatsĪnd is widely used for rasterizing postscript and pdf files.Ī collection of such formats ('output devices' in Ghostscript terminology) Bits per pixel Commonly abbreviated bpp this is the number ofĭigital bits used to represent the color of each pixel. Dots per inch Dots per inch or dpi is the common measure of Known to Ghostscript are defined in the initialization file In PostScript, which specifies exactly 72 points per inch (approximately Predefined in Ghostscript.) Points Points are a measure traditionally used in the printing trade and now The inch measure is sometimesĨ.5in×11in, approximately 21.6cm×27.9cm. Quite close to 210×297 millimeters (approximately 8.3×11.7 The SI units of centimeters and millimeters. Centimeters and millimeters ISO standard paper sizes such as A4 and A3 are commonly represented in Several different important kinds of measures appear throughout thisĭocument: inches, centimeters and millimeters, points, and bits per pixel. We recommend moving to the ijs device for all such printing. In general all older printerĭrivers can be replaced by the ijs interface and one of the available 3rd party rasterĭriver collections. In general such devices are deprecatedĪnd will be removed in future versions of Ghostscript.
