Methods and systems for thickening an interior region of a fill object

A multifunctional device (MFD) for thickening an interior region of a fill object, comprising:

• a processor;
• a digital front end (DFE) module, coupled to the processor, to:
• receive a print job at a multifunctional device (MFD), wherein the print job comprising an input image;
• convert the input image into a digital bitmap image comprised of an array of pixels, wherein each pixel being assigned with a pixel value and an object tag information;
• based on the pixel value and the object tag information, define each pixel as one of a boundary pixel of the input image, an edge pixel of the fill object in the input image, and an interior pixel of the fill object;
• and
• simultaneously fatten the edge pixels and the interior pixels of the fill object by a user-specified amount for applying thickening on an interior region defined by the interior pixels;
• and
• a digital rear end (DRE) module, coupled to the processor, to flatten the edge pixels and the interior pixels for generating an output image for printing at the MFD in such a way that a pixel assumes color of the interior pixels if the pixel is interior pixel originally or becomes interior pixel through the fattening of the interior pixels, and that a pixel assumes color of the edge pixels if the pixel is an edge pixel originally or becomes edge pixel through the fattening of the edge pixels.

A non-transitory computer-readable medium comprising instructions executable by a processing resource to:

• convert an input image into a digital bitmap image comprised of an array of pixels, wherein each pixel being assigned with a pixel value and an object tag information;
• based on the pixel value and the object tag information, define each pixel as one of a boundary pixel of the input image, an edge pixel of the fill object in the input image, and an interior pixel of the fill object;
• simultaneously fatten the edge pixels and the interior pixels of the fill object by a user-specified amount for applying thickening on an interior region defined by the interior pixels;
• and
• flatten the edge pixels and the interior pixels to generate an output image for printing at a multifunctional device (MFD) in such a way that a pixel assumes color of the interior pixels if the pixel is interior pixel originally or becomes interior pixel through the fattening of the interior pixels, and that a pixel assumes color of the edge pixels if the pixel is an edge pixel originally or becomes edge pixel through the fattening of the edge pixels.

A method for thickening an interior region of a fill object, the method being implemented in a multifunctional device (MFD) having a processor, the method comprising:

• receiving a print job at the MFD, wherein the print job comprising an input image;
• converting the input image into a digital bitmap image comprised of an array of pixels, wherein each pixel being assigned with a pixel value representing printing information;
• based on the pixel value, defining each pixel as one of a boundary pixel of the input image, an edge pixel of a fill object in the input image, and an interior pixel of the fill object;
• simultaneously fattening the edge pixels and the interior pixels of the fill object by a user-specified amount for applying thickening to the interior region defined by the interior pixels;
• and
• flattening the edge pixels and the interior pixels for generating an output image for printing the output image at the MFD in such a way that a pixel assumes color of the interior pixels if the pixel is interior pixel originally or becomes interior pixel through the fattening of the interior pixels, and that a pixel assumes color of the edge pixels if the pixel is an edge pixel originally or becomes edge pixel through the fattening of the edge pixels.
