PDFBox - 删除不可见文本（通过 clip/filling 路径问题）
PDFBox - Removing invisible text (by clip/filling paths issue)
Link 示例 PDF：click here。在这里你可以看到左边的很多标签被裁剪了（因为一些裁剪指令）
当我使用 PDFTextStripper 时，它打印示例 PDF 文件中实际上是 cut/hidden 的所有文本。我已经尝试过描述 的解决方案，但它甚至更有价值，因为删除了顶部的大量文本 + 每行开头的一些文本。
有没有其他方法可以使用 PDFBox 仅显示可见字符并跳过所有重叠？或者是否有任何其他工具可以 return 仅显示文本？
提前致谢。
引用的PDFVisibleTextStripper from OP不起作用的原因是覆盖processTextPosition中字符基线end结束的计算没有将页面旋转到帐户。但是，如果您更改该方法，仅测试每个字符基线的开头而忽略结尾，则它对手头的文档非常有效：
@Override
protected void processTextPosition(TextPosition text) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
PDGraphicsState gs = getGraphicsState();
Area area = gs.getCurrentClippingPath();
if (area == null || area.contains(start.getX(), start.getY()))
super.processTextPosition(text);
}
使用此 processTextPosition 覆盖文本提取的结果（SortByPosition 设置为 true）是：

乍一看，唯一缺少的可见文本是两页页脚中的总页数。
正如 OP 在评论中所说
It seems same thing should be applied in deleteCharsInPath()
的确，deleteCharsInPath也应该改成：
void deleteCharsInPath() {
for (List<TextPosition> list : charactersByArticle) {
List<TextPosition> toRemove = new ArrayList<>();
for (TextPosition text : list) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
if (linePath.contains(start.getX(), start.getY())) {
toRemove.add(text);
}
}
if (toRemove.size() != 0) {
System.out.println("Removed " + toRemove.size() + " TextPosition objects as they are being covered.");
list.removeAll(toRemove);
}
}
}
OP 提供了另一份文件，其中甚至 PDFVisibleTextStripper 如上更正也未能正确识别可见字符。
原因是 PDFBox 文本剥离将原点移动到裁剪框的左下角的另一个规范化。
修补 PDFVisibleTextStripper 方法以再次添加左下方的裁剪框坐标值，从而可以很好地提取可见文本。
重写 processPage 允许我们读取左下方的裁剪框坐标：
float lowerLeftX = 0;
float lowerLeftY = 0;
@Override
public void processPage(PDPage page) throws IOException {
PDRectangle pageSize = page.getCropBox();
lowerLeftX = pageSize.getLowerLeftX();
lowerLeftY = pageSize.getLowerLeftY();
super.processPage(page);
}
processTextPosition 和 deleteCharsInPath 需要考虑这些值：
@Override
protected void processTextPosition(TextPosition text) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
PDGraphicsState gs = getGraphicsState();
Area area = gs.getCurrentClippingPath();
if (area == null || area.contains(lowerLeftX + start.getX(), lowerLeftY + start.getY()))
super.processTextPosition(text);
}
[...]
void deleteCharsInPath() {
for (List<TextPosition> list : charactersByArticle) {
List<TextPosition> toRemove = new ArrayList<>();
for (TextPosition text : list) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
if (linePath.contains(lowerLeftX + start.getX(), lowerLeftY + start.getY())) {
toRemove.add(text);
}
}
if (toRemove.size() != 0) {
System.out.println("Removed " + toRemove.size() + " TextPosition objects as they are being covered.");
list.removeAll(toRemove);
}
}
}
现在新文件的提取结果也可以了。 ;)

乍一看，唯一缺少的可见文本是两页页脚中的总页数。
正如 OP 在评论中所说
It seems same thing should be applied in deleteCharsInPath()
的确，deleteCharsInPath也应该改成：
void deleteCharsInPath() {
for (List<TextPosition> list : charactersByArticle) {
List<TextPosition> toRemove = new ArrayList<>();
for (TextPosition text : list) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
if (linePath.contains(start.getX(), start.getY())) {
toRemove.add(text);
}
}
if (toRemove.size() != 0) {
System.out.println("Removed " + toRemove.size() + " TextPosition objects as they are being covered.");
list.removeAll(toRemove);
}
}
}
OP 提供了另一份文件，其中甚至 PDFVisibleTextStripper 如上更正也未能正确识别可见字符。
原因是 PDFBox 文本剥离将原点移动到裁剪框的左下角的另一个规范化。
修补 PDFVisibleTextStripper 方法以再次添加左下方的裁剪框坐标值，从而可以很好地提取可见文本。
重写 processPage 允许我们读取左下方的裁剪框坐标：
float lowerLeftX = 0;
float lowerLeftY = 0;
@Override
public void processPage(PDPage page) throws IOException {
PDRectangle pageSize = page.getCropBox();
lowerLeftX = pageSize.getLowerLeftX();
lowerLeftY = pageSize.getLowerLeftY();
super.processPage(page);
}
processTextPosition 和 deleteCharsInPath 需要考虑这些值：
@Override
protected void processTextPosition(TextPosition text) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
PDGraphicsState gs = getGraphicsState();
Area area = gs.getCurrentClippingPath();
if (area == null || area.contains(lowerLeftX + start.getX(), lowerLeftY + start.getY()))
super.processTextPosition(text);
}
[...]
void deleteCharsInPath() {
for (List<TextPosition> list : charactersByArticle) {
List<TextPosition> toRemove = new ArrayList<>();
for (TextPosition text : list) {
Matrix textMatrix = text.getTextMatrix();
Vector start = textMatrix.transform(new Vector(0, 0));
if (linePath.contains(lowerLeftX + start.getX(), lowerLeftY + start.getY())) {
toRemove.add(text);
}
}
if (toRemove.size() != 0) {
System.out.println("Removed " + toRemove.size() + " TextPosition objects as they are being covered.");
list.removeAll(toRemove);
}
}
}
现在新文件的提取结果也可以了。 ;)
