When I use pdfbox to append pictures, the width of the current page is greater
than the height. When I use 0,0 coordinates to insert, the pictures are
appended to the lower right corner instead of the lower left corner. How can I
solve this??The following is a code example:
PDDocument load = PDDocument.load(new
File("D:\\tv\\e97cd2c6-345d-46dc-ae96-9b757e185ee0.pdf"));
PDPage page = load.getPage(0);
PDPageContentStream contentStream = new PDPageContentStream(load, page,
PDPageContentStream.AppendMode.APPEND, true,true);
PDImageXObject pdImage = PDImageXObject.createFromFile("D:\\tv\\test.png",
load);
PDExtendedGraphicsState pdExtGfxState = new PDExtendedGraphicsState();
pdExtGfxState.setNonStrokingAlphaConstant(0.8f);
pdExtGfxState.setAlphaSourceFlag(true);
pdExtGfxState.getCOSObject().setItem(COSName.BM, COSName.MULTIPLY);
contentStream.setGraphicsStateParameters(pdExtGfxState);
contentStream.drawImage(pdImage, 0, 0, 100, 100);
contentStream.close();
load.save("D:\\tv\\e97cd2c6-345d-46dc-ae96-9b757e185ee0-1.pdf");
From int rotation = page getRotation(); It can be seen that the current PDF is
rotated 270 degrees, and if you add pictures on this basis, the effect pictures
will be inverted??How to solve it
