当我使用如下代码计算权限，即使所有权限都设置好了，在adobe acrobat 中依然会显示文档组合和页面提取 不允许，怎么设置才能让adobe acrobat 中显示允许
// Allow Copy: Enable text/image copying and accessibility tools
if (security.isAllowCopy()) {

permissions |= PdfPermissions.CONTENT_COPY_FOR_ACCESSIBILITY; // 512 - Allow screen readers & accessibility tools

}
// Allow Edit: Enable content editing capabilities (without document assembly)
if (security.isAllowEdit()) {
permissions |= PdfPermissions.MODIFY_CONTENTS; // 8 - Allow editing text/images

permissions |= PdfPermissions.FILL_IN; // 256 - Allow filling forms
log.debug("Edit permissions enabled: MODIFY_CONTENTS (8), MODIFY_ANNOTATIONS (32), FILL_IN (256)");

// Allow Print: Enable all printing capabilities

permissions |= PdfPermissions.PRINTING; // 4 - Allow printing (basic)
permissions |= PdfPermissions.HIGH_RESOLUTION_PRINTING; // 2052 - Allow high-quality printing

// Prevent Merge: Control document assembly operations (page merge/split/insert)

permissions |= PdfPermissions.DOCUMENT_ASSEMBLY; // 1024 - Allow page operations (merge/split/insert)

} else {
log.debug("Document assembly permission DISABLED (preventMerge=true)");
}
return permissions;
1.文档组合和页面提取未生效
2.PDF密码已设置，使用用户密码和所有者密码进入都显示不允许
3. 在福昕PDF阅读器中，使用user 密码进入只显示 页面提取不允许，使用所有者密码进入全部都是允许

用户提供了具体的代码和问题描述，涉及使用 Aspose.Words for Java 将 Word 转 PDF 时设置加密和权限后，在 Adobe Acrobat 中权限显示不一致的问题。问题包含可复现的代码逻辑、权限配置细节及不同 PDF 阅读器（Adobe Acrobat 和 福昕）的行为差异，属于代码调试与权限配置问题。
@kaihufreyrsolutions.com PDF 文档权限的指定仅限于 PdfPermissions。枚举中的项目反映了可以为 PDF 文档指定的权限。
这些被指定的权限不能被adobe acrobat 支持吗
@kaihufreyrsolutions.com 可用权限根据 PDF 规范实现。Adobe Acrobat 的用户界面可能与 PDF 格式规范中的描述有所不同。
