This class represents color space. User can use this class to covert colors.
Convert input color to the color in current color space.
[in] | color | Input color, which is to be converted to current color space. |
- (FSColor *) convertColorWithCMYKColor: | (int) | c_value | |
m_value: | (int) | m_value | |
y_value: | (int) | y_value | |
k_value: | (int) | k_value | |
Convert input C/M/Y/K component values to a color object in current color space.
[in] | c_value | C component value. Valid range: from 0 to 255. |
[in] | m_value | M component value. Valid range: from 0 to 255. |
[in] | y_value | Y component value. Valid range: from 0 to 255. |
[in] | k_value | K component value. Valid range: from 0 to 255. |
- (FSColor *) convertColorWithRGBColor: | (int) | r_value | |
g_value: | (int) | g_value | |
b_value: | (int) | b_value | |
Convert input R/G/B component values to a color in current color space.
[in] | r_value | R component value. Valid range: from 0 to 255. |
[in] | g_value | G component value. Valid range: from 0 to 255. |
[in] | b_value | B component value. Valid range: from 0 to 255. |
- (FSColorSpaceType) getColorSpaceType |
Get color space type.
- (int) getComponentCount |
Get the count of components.
For different color space type, the count of components are not the same.
- (NSArray< NSData * > *) getComponentNames |
Get a string array which represents the name of colorant for Separation color space, or names specifying the individual color components for DeviceN color space.
This function is only available when current color space type is FSColorSpaceSeparation or FSColorSpaceDeviceN. For other color space type, this function will return an empty string array.
- (id) initWithOther: | (FSColorSpace*) | other |
Constructor, with another color space object.
[in] | other | Another color space object. |
- (id) initWithType: | (FSColorSpaceType) | type |
Constructor, with specified color type.
[in] | type | The color space type. Currently, this value can only be one of following values: FSColorSpaceDeviceGray, FSColorSpaceDeviceRGB, FSColorSpaceDeviceCMYK. For other unsupported color space type, exception FSErrUnsupported will be thrown. |
- (BOOL) isEmpty |
Check whether current object is empty or not.
When the current object is empty, that means current object is useless.
- (BOOL) isSpotColorSpace |
Check whether current color space object is a spot color space or not.
