Abstract
Abstract A character compressing method is disclosed wherein a character is separately grouped at a predetermined pitch in the horizontal direction (row direction) or vertical direction (column direction), and a dot start position and continuous dot length are used as a data for each section having a print dot. In a character modifying method using a character data stored in the manner following the character compressing method, the dot start position data and continuous dot length data are derived as fundamental parameters, the data is subjected to a character modifying operation corresponding to one of various modifying modes, and in accordance with the operation results, the dot start address is changed and print dot information corresponding in amount to the continuous dot length is given.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
124 words
A character modifying method comprising the steps of: reading from a memory a print dot start position data and continuous dot length data for each row or column having a print dot of a character whose dots have been assigned to a bit map made of m rows and n columns; performing a character modification operation corresponding to the contents of a character modification, with respect to said print dot start position data and said continuous dot length data to obtain modified dot print information; and setting obtained modified dot print information as to the addresses defined by a continuous dot length obtained by said character modification operation, at new addresses obtained by said character modification operation for said print dot start position data.
Claim 2
Dependent Claim
124 words
A character modifying method comprising the steps of: reading from a memory a print dot start position data and continuous dot length data for each row or column having a print dot of a character whose dots have been assigned to a bit map made of m rows and n columns; performing a character modification operation corresponding to the contents of a character modification, with respect to said print dot start position data and said continuous dot length data to obtain modified dot print information; and setting obtained modified dot print information as to the addresses defined by a continuous dot length obtained by said character modification operation, at new addresses obtained by said character modification operation for said print dot start position data.
Claim 3
Dependent Claim
26 words
The character modifying method according to claim 1, wherein said character modification is at least one selected from the group consisting of expansion, condensation and emphasis.
Claim 4
Dependent Claim
24 words
The character modifying method according to claim 1, wherein said character modification operation is carried out in the row direction of the print dots.
Claim 5
Dependent Claim
131 words
The character modifying method according to claim 1, comprising providing, in said memory, print information related to said dots in said print map, wherein said print information comprises: a most significant bit indicating that a set of continuous print dots is in the last one in the row or column or that another set of continuous dots exist in the row or column; a bit next to the most significant bit indicating that the data size is one byte or two bytes; and if said data size is one byte, the third and following bits representing number of dots and dot position, or if said data size is two bytes, a third and following bits of a first byte representing dot position and the second byte data representing number of dots.
