Print on Retransfer Film functions

The API provides the following printing functions:

♦ Image Out Function

♦ Define LUT Function

♦ Print Function

Image Out Function

No. Function Name Explanation

1 int CXCMD_ImageOut

(int iSlot, int iID,

BYTE * pbyPlane,

int iLength,

int iColor,

int iBuffer)

Transfers image data to the printer by using Image Out

command.

pbyPlane Image Data. The size of image data must be

1036 x 664 bytes.

iLength Size of image data in bytes, which must be 1036 x

664.

iColor Kind of image data.

0 if image data is for K (black) ink.

1 if image data is for C (Cyan or blue) ink.

2 if image data is for M (Magenta) ink.

3 if image data is for Y (Yellow) ink.

4 if image data is for UV ink.

5 if image data is for Peel Off.

iBuffer Image Data buffer number. The printer has two

image buffers for all images. Specify:

0 to use Buffer 0.

1 to use Buffer 1.

How to Translate RGB to YMC Planes

The SR200 & SR300 printers support printing to YMC planes to print a colored

image. If the source image is in RGB format, it must be transformed to Y, M and C

planes. Normally, the formula to translate RGB to YMC is as follows.

Y = 255-B, M = 255-G, C = 255-R

About K Printing

K ink is used for crisp, high-quality printing of black text. The data for K ink is

Boolean (or 1 bit per pixel), where 0 stands for white or no printing, and 1 is black

and is printed.
