生成水印图片
- 获取背景透明的水印图片
BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
Graphics2D g2d = image.createGraphics();
image = g2d.getDeviceConfiguration().createCompatibleImage(width, height, Transparency.TRANSLUCENT);
g2d.dispose();
g2d = image.createGraphics();
- 直接在图片上添加图片水印
public void mark(BufferedImage bufImg, Image img, Image markImg, int width, int height, int x, int y) {
Graphics2D g = bufImg.createGraphics();
g.drawImage(img, 0, 0, bufImg.getWidth(), bufImg.getHeight(), null);
g.drawImage(markImg, x, y, width, height, null);
g.dispose();
}
- 直接在文字上添加水印
public void mark(BufferedImage bufImg, Image img, String text, Font font, Color color, int x, int y) {
Graphics2D g = bufImg.createGraphics()
g.drawImage(img, 0, 0, bufImg.getWidth(), bufImg.getHeight(), null)
g.setColor(color)
g.setFont(font)
g.drawString(text, x, y)
g.dispose()
}
pdf打水印
用上面生成的图像 直接打到对应的pdf文件中即可
1.水印的方向 大小等通过对Image的调整即可实现
2.水印的位置通过addImage复写方法中的6个参数即可决定
package com.trs.wsg.pdf.itext
import java.io.FileOutputStream
import com.itextpdf.text.BaseColor
import com.itextpdf.text.Element
import com.itextpdf.text.Image

public PdfAddWaterMark() {
// TODO Auto-generated constructor stub
}
public void addWaterMark(String srcFile, String destFile, String text,
int textWidth, int textHeight) throws Exception
{
// 待加水印的文件
PdfReader reader = new PdfReader(srcFile)
// 加完水印的文件
PdfStamper stamper = new PdfStamper(reader, new FileOutputStream(
destFile))
int total = reader.getNumberOfPages() + 1
PdfContentByte content
// 设置字体
// BaseFont font = BaseFont.createFont()
BaseFont basefont = BaseFont.createFont("c:/windows/fonts/SIMYOU.TTF", BaseFont.IDENTITY_H, BaseFont.NOT_EMBEDDED)
//设置透明度
PdfGState gs = new PdfGState()
gs.setFillOpacity(1f)
gs.setStrokeOpacity(1f)
// 循环对每页插入水印
for (int i = 1
{
// 水印的起始
content = stamper.getUnderContent(i)
// 开始
content.beginText()
// 设置颜色 默认为蓝色
content.setColorFill(BaseColor.GRAY)
// content.setColorFill(Color.GRAY)
// 设置字体及字号
content.setFontAndSize(basefont, 38)
// 设置起始位置
// content.setTextMatrix(400, 880)
content.setTextMatrix(textWidth, textHeight)
// 开始写入水印
content.showTextAligned(Element.ALIGN_LEFT, text, textWidth,
textHeight, 45)
content.endText()
//t添加图片水印
Image img2 = Image.getInstance("D:\\s.png")
img2.setRotationDegrees(45)
img2.setAbsolutePosition(0, 0)
content.addImage(img2)
}
stamper.close()
}
}
视频打水印
通过ffmepmg程序，调用系统方法实现。
