The pattern created with PDFBox shows inconsistent colors between Safari and
Adobe.
It appears red in Adobe and Chrome, which is correct.
It appears blue in Safari, which is incorrect.
Here is the example code:
{code:java}
try (PDDocument document = new PDDocument()) {
PDPage page = new PDPage();
document.addPage(page);
try (PDPageContentStream contentStream = new
PDPageContentStream(document, page)) {
PDTilingPattern pattern = new PDTilingPattern();
pattern.setBBox(new PDRectangle(3, 3));
pattern.setPaintType(PDTilingPattern.PAINT_UNCOLORED);
pattern.setTilingType(PDTilingPattern.TILING_CONSTANT_SPACING);
pattern.setXStep(3);
pattern.setYStep(3);
pattern.setMatrix(Matrix.getScaleInstance(1,
1).createAffineTransform());
try (PDPatternContentStream patternContentStream = new
PDPatternContentStream(pattern)) {
patternContentStream.setLineWidth(0.4f);
patternContentStream.moveTo(0, 2);
patternContentStream.lineTo(0, 3);
patternContentStream.lineTo(2, 3);
patternContentStream.lineTo(2, 2);
patternContentStream.lineTo(3, 2);
patternContentStream.lineTo(3, 0);
patternContentStream.lineTo(2, 0);
patternContentStream.lineTo(2, 1);
patternContentStream.lineTo(1, 1);
patternContentStream.lineTo(1, 2);
patternContentStream.closePath();
patternContentStream.fill();
} catch (IOException e) {
throw new RuntimeException(e);
};
COSName patternName = page.getResources().add(pattern);
PDPattern pdPattern = new PDPattern(page.getResources(),
PDDeviceRGB.INSTANCE);
PDColor pdColor = new PDColor(Color.RED.getComponents(null),
patternName, pdPattern);
contentStream.setNonStrokingColor(pdColor);
contentStream.addRect(100, 500, 400, 200);
contentStream.fill();
}
document.save("excel_pattern_fill.pdf");
}
{code}
