PDFBox gets wrong font color values from PDF file!
Hello,
In this sample PDF file:
https://www.dropbox.com/s/2z5b3vrvnzjo0lo/Font%20color%20Sample.pdf?dl=0
I am trying to check the font colors for all letters, but I have noticed
that PDFBox gets colors with values partially different from the ones that I
see in Adobe Acrobat. I use this code:
@Override
public void processTextPosition( TextPosition t ) {
try {
PDGraphicsState gs = getGraphicsState();
Color color = new Color( gs.getNonStrokingColor().toRGB() );
System.out.println( color.getRed() );
System.out.println( color.getGreen() );
System.out.println( color.getBlue() );
}
catch (IOException ioe) {}
}
For example PDFBox prints the values:
Red:64, Green:96, Blue:172
While in Adobe Acrobat the values appear as:
Red:66, Green:105, Blue:178
Is there a reason for this?
Best regards,
Hesham

Now it's clear. Thanks a lot Tilman 😊

It's the CMYK icc profile from Adobe. We can't include it because of the license. We use a different icc profile.
The code below reinitializes the CMYK colorspace with that icc profile.

That has fixed this, and the colors appear with right RGB values now!
I am not sure what this file does, but it has fixed it!
Thanks a lot Tilman.

Tilman,
I haved used exactly the same code in the "PrintTextColors.java" to print the colors in my PDF sample. I have just added a couple of lines to the processTextPosition(...) method to print the RGB colors, like this:
@Override
protected void processTextPosition( TextPosition text ) {
try {
super.processTextPosition(text);
PDColor strokingColor = getGraphicsState().getStrokingColor();
PDColor nonStrokingColor = getGraphicsState().getNonStrokingColor();
Color fontColor = new Color( nonStrokingColor.toRGB() );
String unicode = text.getUnicode();
RenderingMode renderingMode = getGraphicsState().getTextState().getRenderingMode();
System.out.println("Unicode: " + unicode);
System.out.println("Rendering mode: " + renderingMode);
System.out.println("Stroking color: " + strokingColor);
System.out.println("Non-Stroking color: " + nonStrokingColor);
System.out.println("Non-Stroking color: " + nonStrokingColor);
System.out.println("Letter color: " + fontColor.getRGB() + " => R:" + fontColor.getRed() + ", G:" + fontColor.getGreen() + ", B:" + fontColor.getBlue() );
System.out.println();
}
catch (IOException ioe) {}
}
In my sample PDF file there is the title "Strawberry Smoothie and Fruit Toast" for example. It prints the following for the first "S" letter:
Unicode: S
Rendering mode: FILL
Stroking color: PDColor{components=[0.0], patternName=null}
Non-Stroking color: PDColor{components=[0.805, 0.613, 0.0, 0.0], patternName=null}
Non-Stroking color: PDColor{components=[0.805, 0.613, 0.0, 0.0], patternName=null}
Letter color: -12558164 => R:64, G:96, B:172
The last line shows the RGB colors, which appear different in Adobe Acrobat.
I hope my exaplanation now is more clear.
Best regards,
Hesham

Yes but what colors are wrong? All of them, some of them, or what?
I can't investigate if you're not telling me where you searched.
The example tool also outputs some text. That makes it easier to find the actual color command in the content stream.

Thanks Telman!
I have tested the PrintTextColors example and I am getting the same results!
Still, PDFBox reports RGB values different than the ones I see in Adobe
Acrobat when using the PrintTextColors example with my PDF sample.

Hi,
Please use the PrintTextColors example and combine this to your code,
then show where these colors come up, i.e. for what glyph. Hopefully at
