Reverse upsampling method and system

A method for reducing the storage required for an image, wherein the image comprises a first plurality of pixels of an image in memory with contone colors, and a second plurality of linework pixels of an image in memory with at least one linework color, the method comprising:

• determining which pixels in a first row of pixels in the image may be coalesced with a second row of pixels in the image, wherein any continuous tone pixels along said first row may be coalesced with an adjacent continuous tone pixel of the same color in said second row and an adjacent linework pixel of any color in said second row;
• determining which pixels along a first column of pixels in the image may be coalesced with a second column of pixels in the image, wherein any continuous tone pixels along said first column may be coalesced with an adjacent continuous tone pixel of the same color in said second column and an adjacent linework pixel of any color in said second column;
• coalescing the pixels along said first row with the pixels along said second row;
• and coalescing the pixels along said first column with the pixels along said second column;
• and
• transmitting the image from memory.

A method for reducing the storage required for an image, wherein the image comprises a plurality of pixels of an image in memory and each pixel comprises a color, the method comprising:

• determining pixels of the image in a first row to be coalesced with pixels along an adjacent row;
• determining pixels in a first column to be coalesced with pixels along an adjacent column;
• coalescing the pixels in said first row with the pixels in said adjacent row;
• and coalescing the pixels in said first column with the pixels along said adjacent column;
• and
• transmitting the image from memory.

A computing apparatus having a processor and a memory having computer executable instructions for performing the method for reducing image data, the method comprising:

• inputting into memory an image comprising a plurality of pixels;
• determining a first set of pixels of the image to be coalesced with a second set of pixels of the image, the first and second sets being adjacent to one another and being oriented in a first direction;
• determining a third set of pixels of the image to be coalesced with a fourth set of pixels of the image, the third and fourth sets being adjacent to one another and being oriented in a second direction;
• coalescing the first and second sets of pixels;
• and coalescing the third and fourth sets of pixels.

A computer readable medium having computer executable instructions for performing the method for reducing image data, the method comprising:

• inputting into memory an image comprising a plurality of pixels;
• determining a first set of pixels of the image to be coalesced with a second set of pixels of the image the first and second sets being adjacent to one another and being oriented in a first direction;
• determining a third set of pixels of the image be coalesced with a fourth set of pixels of the image, the third and fourth sets being adjacent to one another and being oriented in a second direction;
• coalescing the first and second sets of pixels;
• and coalescing the third and fourth sets of pixels.
