6.25 Transfer Raster image “ESC i r c b nL nH mL mH d1......dk”
Format:
ASCII ESC I r c b nL nH mL mH d1 d2…dk
Hex 1B 69 r c b nL nH mL mH d1 d2…dk
Decimal 27 105 r c b nL nH mL mH d1 d2…dk
Range of Values for Parameters:
r = 00H, 01H, 02H, 04H
c = 00H, 01H
b = 01H, 02H
0000H <= ( nH*256 + nL ) <= 7FFFH
0001H <= ( mH*256 + mL ) <= 7FFFH
Function:
1) Prints dot graphics in raster format.
2) Parameters are used as described below:
r : color of image ( 00H:black, 01H:magenta, 02H:cyan, 04H:yellow )
c : compress method ( 00H:noncompressed, 01H:Run Length
Encoding )
b : bit length of each pixel ( 01H:1bit/pixel (for Micro, Normalx1,
Normalx2, Normalx4 dot)
nL, nH: Horizontal byte count, according to the following formula:
nH = INT( horizontal byte count / 256 )
= INT( ( ( horizontal dot count ) * ( bit lenght of each pixel ) + 7 ) /
8 ) /256
nL = MOD(horizontal byte count / 256 )
= MOD( ( ( horizontal dot count ) * ( bit lenght of each pixel ) + 7
) / 8 ) /256
mL, mH: Vertical dot count ( rows of dot graphics ), according to the
following formula:
mH = INT(vertical dot count / 256 )
mL = MOD(vertical dot count / 256 )
k : Total numbers of data bytes, accoriding to the following formula:
k = ( nH*256 + nL ) * ( mH*256 + mL )
Initial State: -
