在OpenTBS演示中，图像被替换，这在代码中的哪里完成

Question

我无法理解如何管理映像替换。因此，我查看了演示项目(demo_ms_word.php(，但找不到定义和实际图像替换完成的php代码。

模板

[b.number;ope=changepic;from=pic_[val].png;tagpos=inside;adjust;unique]

PHP(仅显示主要部分，不包括和输出(

$TBS->PlugIn(OPENTBS_CHART, $ChartNameOrNum, $SeriesNameOrNum, $NewValues, $NewLegend);
// Delete comments
$TBS->PlugIn(OPENTBS_DELETE_COMMENTS);

有人能指出图像的定义并将其合并到替换的位置吗？

Answer 1

在模板中，字段名为[b.number;...]，因此它与名为"b"的块(或字段(和子项number合并。

我们在PHP代码段中看到它对应于$TBS->MergeBlock('a,b', $data);。此代码正在将块"a"one_answers"b"与记录集$data合并。

因此[b.number;...]与记录集$data的列number合并。Yo可以看到该列具有诸如"1523d"、"1234f"等值。。。

参数ope=changepic使字段的值成为要替换的图片的路径。但最终路径是用参数from=pic_[val].png排列的，该参数使字段"1523d"的值对应于路径"pic_1523d.png"。这就是画面的变化。

如果字段的值直接是要替换的图像的路径，则ope=changepic不需要参数"from"。
