摘要： Non integer scaling of images to reduce artifacts is presented herein. One embodiment includes determining a scaling resolution based on a pixel resolution of the image and a pixel resolution of an output device (i.e., factors of the scaling resolution). The image is converted to the scaling resolution to change (e.g., increase) the pixels of the image by the first factor. A grid is generated to scale the converted image. The grid has a number of sections defined according to the second factor times the pixel resolution of an output device. The converted image is sectioned according to the grid. Each section of the grid includes an integer number of pixels of the converted image. The color values of the pixels of the converted image are averaged within each section of the grid to compute a single color value for each section of the grid and scale the image.

摘要： Systems and associated methods provide for converting an RGB color image to a grayscale image via a lookup table of correction values. The lookup table is generated and used to compensate for errors in converting the color image to the grayscale image. The lookup table is generated by generating a reference image having pixels with color values in the RGB color space, converting a first copy of the reference image to a grayscale reference image via interpolation, and converting a second copy of the reference image to an intermediate image. The intermediate image comprises chrominance and luminance values (e.g., YCbCR or YCgCo). The chrominance values are removed from the intermediate image. The intermediate image is then compared to the grayscale reference image to generate the correction values. The lookup table may then be applied to a grayscale image that has been converted from the RGB color image.

摘要： Methods and systems are disclosed herein for print data transformation using conversion arrays. A print datastream is received, where the print datastream includes bitmap data encoded as a first number of bits per pel. An array of conversion values is retrieved to convert the bitmap data to a second number of bits per pel encoding. The bitmap data is then converted using the array to the second number of bits per pel encoding, where one or more bytes of the bitmap data is used as an index to the array to generate output data. A printed output is generated based on the output data.
