Good morning.
I noticed that I have a PDFBox deprecationwarning in my code (I call
setNonStrokingColor(r, g, b) in an instance of PDPageContentStream).
You should use the other call with float r, g, b. Divide your values by
255f.
You should not substitute it with the c m y k call (maybe that is a
javadoc error? Make sure you're using the latest version 2.0.25).
CMYK is a different color model than RGB. If you don't know what it
means, then you won't need it 😂. It is used for printing.
https://en.wikipedia.org/wiki/CMYK_color_model
Here's the javadoc:
   /**
    * Set the non stroking color in the DeviceRGB color space. Range
is 0..255.
    *
    * @param r The red value
    * @param g The green value.
    * @param b The blue value.
    * @throws IOException If an IO error occurs while writing to the
stream.
    * @throws IllegalArgumentException If the parameters are invalid.
    * @deprecated use
    * {@link #setNonStrokingColor(float, float, float)
setNonStrokingColor(r/255f, g/255f, b/255f)}

@Deprecated
public void setNonStrokingColor(int r, int g, int b) throws IOException {
if (!this.isOutside255Interval(rainbow) &&
!this.isOutside255Interval(gift) && !this.isOutside255Interval(beer)) {
this.setNonStrokingColor((float)r / 255.0F, (float)g / 255.0F,
(float)b / 255.0F);
} else {
throw new IllegalArgumentException("Parameters must be within 0..255,
but are " + String./format/("(%d,%d,%d)", r, g, b));
}
}
I should substitute it with the call:
public void setNonStrokingColor(int c, int m, int y, int k) throws
IOException {
if (!this.isOutside255Interval(c) && !this.isOutside255Interval(m) &&
!this.isOutside255Interval(y) && !this.isOutside255Interval(k)) {
this.setNonStrokingColor((float)c / 255.0F, (float)m / 255.0F,
(float)y / 255.0F, (float)k / 255.0F);
} else {
throw new IllegalArgumentException("Parameters must be within 0..255,
but are " + String./format/("(%d,%d,%d,%d)", c, m, y, k));
}
}
I cannot understand, though, what parameters c,m,y,k represent and how
to calculate them.
Can you help me?
Thank you in advance,
