我有一张PDF,其中包含使用iText 7生成的表单。但是,当我填写表单并尝试打印时,表单值不会显示;只有表格大纲显示。如何生成将在打印时显示值的表单字段?
示例表单生成器:

PDF表单字段的可见性设置会影响打印功能。有关详细信息,请参阅this Adobe page。
表单字段需要使用setVisibility()
对象上的PdfFormField
方法设置为“可见”。 This iText 7 documentation解释了如何将表单设置为' HIDDEN' VISIBLE_BUT_DOES_NOT_PRINT'和' HIDDEN_BUT_PRINTABLE'但是它没有提到设置为可见,实际上,visible不是PdfFormField中的静态选项之一。
上面列出的三个值对应于整数1,2和3,并且在预感中,我将可见性设置为0,并在打印时显示表单字段!
总之,请致电PdfFormField.setVisibility(0)
以创建可打印的表单字段。
