有人有处理 Nuance OmniPage SDK XML 格式的经验吗？

我正在使用 Nuance OmniPage SDK 对图像和 PDF 执行 OCR，对于我的一种情况，我必须解析 OCR 在识别文件时生成的 XML 文件，但这些数字实际上没有意义。以下是 SDK 的示例输出：

<page ocr-vers="OmniPageCSDK16" app-vers="OfficeDrop">
    <description backColor="ffffff">
        <source
            file="C:\Users\workspace\jobs\src\test\resources\test-docs\0003.tiff"
            dpix="300" dpiy="300" sizex="2480" sizey="3509" />
        <theoreticalPage size="Custom" marginLeft="0"
            marginTop="0" marginRight="0" marginBottom="0" width="2480" height="3509" />
    </description>
    <zones>
        <textZone l="1814" t="1517" r="4694" b="1733" fillingMethod="omnifont"
            recognitionModule="omnifontPlus2w" chrFilter="all">
            <ln l="1814" t="1517" r="4690" b="1728" baseLine="1680"
                underlined="none" fontSize="1100">
                <wd l="1814" t="1517" r="2539" b="1728">Sample</wd>
                <space width="67" />
                <wd l="2606" t="1541" r="2995" b="1680">text</wd>
                <space width="72" />
                <wd l="3067" t="1570" r="3302" b="1680">on</wd>
                <space width="72" />
                <wd l="3374" t="1517" r="3734" b="1680">line</wd>
                <space width="91" />
                <wd l="3826" t="1522" r="3912" b="1680">1</wd>
                <space width="82" />
                <wd l="3994" t="1570" r="4459" b="1728">page</wd>
                <space width="91" />
                <wd l="4550" t="1522" r="4690" b="1680">1.</wd>
                <space />
            </ln>
        </textZone>
    </zones>
</page>

页面大小定义很容易计算出来，((2480 * 72) / 300) 将为我提供最终 PDF 页面的正确页面宽度（以磅为单位）（然后是高度），但其他值没有任何意义。

1100 的字体大小是多少？那么这些词的坐标呢？他们如何拥有页面上不存在的位置的坐标？

有谁知道这个 XML 格式是什么或者可以指导我做文档吗？我搜索了 SDK 附带的所有手册，但仍然找不到与这些值代表的内容或它们使用的单位相关的任何内容（我确信它不是像素或点，我猜）。

任何帮助表示赞赏。我正在使用 java 绑定来访问 OmniPage C SDK。

I am using the Nuance OmniPage SDK to perform OCR on images and PDFs, for one of my cases I have to parse the XML file the OCR generates when recognizing a file, but the numbers don't really make sense. Here's a sample output for the SDK:

<page ocr-vers="OmniPageCSDK16" app-vers="OfficeDrop">
    <description backColor="ffffff">
        <source
            file="C:\Users\workspace\jobs\src\test\resources\test-docs\0003.tiff"
            dpix="300" dpiy="300" sizex="2480" sizey="3509" />
        <theoreticalPage size="Custom" marginLeft="0"
            marginTop="0" marginRight="0" marginBottom="0" width="2480" height="3509" />

        <textZone l="1814" t="1517" r="4694" b="1733" fillingMethod="omnifont"
            recognitionModule="omnifontPlus2w" chrFilter="all">
            <ln l="1814" t="1517" r="4690" b="1728" baseLine="1680"
                underlined="none" fontSize="1100">
                <wd l="1814" t="1517" r="2539" b="1728">Sample</wd>
                <space width="67" />
                <wd l="2606" t="1541" r="2995" b="1680">text</wd>
                <space width="72" />
                <wd l="3067" t="1570" r="3302" b="1680">on</wd>
                <space width="72" />
                <wd l="3374" t="1517" r="3734" b="1680">line</wd>
                <space width="91" />
                <wd l="3826" t="1522" r="3912" b="1680">1</wd>
                <space width="82" />
                <wd l="3994" t="1570" r="4459" b="1728">page</wd>
                <space width="91" />
                <wd l="4550" t="1522" r="4690" b="1680">1.</wd>
                <space />
            </ln>
        </textZone>
    </zones>
</page>

The page size definition is quite easy to figure out, ((2480 * 72) / 300) is going to give me the correct page width in points (and then the height) for the final PDF page, but the other values don't make any sense.

What is this font-size of 1100? And these word coordinates? How can they have coordinates that are in positions that do not exist on the page?

Is there anyone out there that knows what this XML format is or that could point me do documentation? I have searched around all manuals that came with the SDK and I still can't find anything related to what these values represent or which unit they are using (i'm sure it isn't pixels or points, i guess).

Any help is appreciated. I'm using java bindings to access the OmniPage C SDK.
