I have a program that updates drwing notes per regen.  If a note loses it reference I want to change color.   Theres a colorset function, but I am struggling to set up a ProColor datatype.   Does anyone have an example of setting up a ProColor datatype. ?      Thanks for any assistance.

Let me close this topic out:  The original question was that I wanted to change a note color, there are functions to do that but you need to set up a ProColor datatype.   I found the definition confusing with a union, and colormap threw me as well, if I wanted to use different ColorMethods.   


typedef struct pro_color
{
 ProColorMethod method;
 union {
	ProColortype type;
	ProColormap map;
 } value;
} ProColor;

There are not many examples of setting up but eventually found a couple buried in functions I wasnt using. 

To set color to a standard Creo  using color type:    ProColorType is an enum with defined values for standard Creo colors.

 

  ProColor MyColor;

 

MyColor.method = PRO_COLOR_METHOD_TYPE;

MyColor.value.type = PRO_COLOR_LETTER;
err = ProDtlnotedataColorSet(notedata, &MyColor);

 

 

To define a custom color ( I wanted magenta) 

MyColor.method = PRO_COLOR_METHOD_RGB;
MyColor.value.map.red = 1.0;
MyColor.value.map.green = 0;
MyColor.value.map.blue = 1.0;
err = ProDtlnotedataColorSet(notedata, &MyColor);

 

As I stated in previous post you can use RGB chart.  Most softwares use values 0 to 255,    Creo uses 0 to 1, just compress the 255 values to terms of one.

My issue was more concerned dealing with the Color structure, the fact that it contains Union,  and how to manipulate as I could find few examples. 

 

typedef enum pro_color_method
{
 PRO_COLOR_METHOD_DEFAULT,
 PRO_COLOR_METHOD_TYPE,
 PRO_COLOR_METHOD_RGB
} ProColorMethod;

typedef struct pro_color
{
 ProColorMethod method;
 union {
	ProColortype type;
	ProColormap map;
 } value;
} ProColor;
 color.method = PRO_COLOR_METHOD_TYPE;
 color.value.type = (ProColortype)color_index;

 I did finally find an example of setting up and RGB example and it was pretty simple.  With MyColor as a ProColor, I wanted to change a note to Cyan so I used the following lines to set up my Color varaiable.:

 

MyColor.method = PRO_COLOR_METHOD_RGB;
MyColor.value.map.red = 0;
MyColor.value.map.green = 1.0;
MyColor.value.map.blue = 1.0;

 

using this RGB color chart to help me figure out values,  In Creo rgb values go from 0 to 1 as opposed to 0 to 255

divide an integer value from color dialog box by maximum possible value ( double 255.0). cast result to double.
