# Extract Worksheet (Column) Values

## Recommended Posts

Hi,

I'm creating a script that convert RGB to CMYK, the Calc it's OK. But, I need to know, how can I extract the information (Values in numbers) contained in worksheet cell (R, G, B Column) to put in VAR (r,g,b)  and after the calc process, paste the result of Cstr, Mstr, Ystr and Kstr in other Worksheet Cell Like (C, M, Y, K Column).

The worksheet name is: CMYK,

PROCEDURE RGBToCMYK;
{ ------------------------------------------------------ }

CONST { ONLY TO TEST}
r = 127;
g = 255;
b = 212;
{ ------------------------------------------------------ }

VAR
c, m, y, k : REAL;

{r, g, b : LONGINT}
Cstr, Mstr, Ystr, Kstr : STRING;

BEGIN
c := 1 - ( r / 255 );
m := 1 - ( g / 255 );
y := 1 - ( b / 255 );
k := 1;

IF ( c < k ) THEN k := c;
IF ( m < k ) THEN k := m;
IF ( y < k ) THEN k := y;
c := ( c - k ) / ( 1 - k );
m := ( m - k ) / ( 1 - k );
y := ( y - k ) / ( 1 - k );

Cstr := NUM2STR(4, c);
Mstr := NUM2STR(4, m);
Ystr := NUM2STR(4, y);
Kstr := NUM2STR(4, k);

MESSAGE(CONCAT(Cstr, ' ', Mstr, ' ', Ystr, ' ', Kstr));
END;
RUN(RGBToCMYK);

You are not going to use Cut/Copy and Paste. You are going to have to read the cell, do the calculations and then write the data to the correct cell.

Check out the GetWSCellValue in the Function Reference for getting values from cell.

Use SetWSCellFormula to store a value into a cell.  The name is a little misleading, but a number is considered a valid "formula" in a cell.

Hi Pat, How Are you?

Thanks, I appreciate your help.

Before I reading your message, I did it that way below:

PROCEDURE RGBToCMYK;
{ ------------------------------------------------------ }

{CONST {TESTE}
{r = 127;
g = 255;
b = 212;}
{ ------------------------------------------------------ }

VAR
c, m, y, k : REAL;
vred, vgreen, vblue : LONGINT;
Cstr, Mstr, Ystr, Kstr : STRING;
hplan : HANDLE;
numRows, numColumns : INTEGER;
vlin : INTEGER;

BEGIN

hplan := GetObject('_Plan_Teste);
IF (hplan <> NIL) THEN GetWSRowColumnCount(hplan, numRows, numColumns);

vlin := 2;

REPEAT

vred := Str2Num(GetCellStr(hplan, vlin, 4));
vgreen := Str2Num(GetCellStr(hplan, vlin, 5));
vblue := Str2Num(GetCellStr(hplan, vlin, 6));

c := 1 - ( vred / 255 );
m := 1 - ( vgreen / 255 );
y := 1 - ( vblue / 255 );
k := 1;

IF ( c < k ) THEN k := c;
IF ( m < k ) THEN k := m;
IF ( y < k ) THEN k := y;
c := ( c - k ) / ( 1 - k );
m := ( m - k ) / ( 1 - k );
y := ( y - k ) / ( 1 - k );

Cstr := NUM2STR(4, c);
Mstr := NUM2STR(4, m);
Ystr := NUM2STR(4, y);
Kstr := NUM2STR(4, k);

vlin := vlin+1;

message('Linha:', vlin);

UNTIL(vlin>numRows);

END;

RUN(RGBToCMYK);

Any comments in this code?
