No. All analysis is performed on your own server using PHP. ### How accurate is the image resolution check? Resolution is estimated from the image pixel dimensions relative to the page size. It is a strong indicator but, for pixel-perfect placement analysis, use a professional prepress RIP. ### Can I generate a real downloadable PDF report? Yes. The report exports as a self-printing HTML page (browser “Save as PDF”). If you install a PDF engine such as Dompdf and hook the `pdf_preflight_render_pdf` filter, a true PDF binary is produced. ## 使用者評論 這個外掛目前沒有任何使用者評論。 ## 參與者及開發者 以下人員參與了開源軟體〈AlphaPrepress PDF Preflight〉的開發相關工作。 參與者 * [ alphaprepress ](https://profiles.wordpress.org/alphaprepress/) [將〈AlphaPrepress PDF Preflight〉外掛本地化為台灣繁體中文版](https://translate.wordpress.org/projects/wp-plugins/alphaprepress-pdf-preflight) ### 對開發相關資訊感興趣？ 任何人均可[瀏覽程式碼](https://plugins.trac.wordpress.org/browser/alphaprepress-pdf-preflight/)、 查看 [SVN 存放庫](https://plugins.svn.wordpress.org/alphaprepress-pdf-preflight/)， 或透過 [RSS](https://plugins.trac.wordpress.org/log/alphaprepress-pdf-preflight/?limit=100&mode=stop_on_copy&format=rss) 訂閱[開發記錄](https://plugins.trac.wordpress.org/log/alphaprepress-pdf-preflight/)。 ## 變更記錄 #### 1.1.1 * Fix: Uploaded files are now stored through the WordPress upload API (`wp_handle_upload()`) instead of direct PHP file functions. * Fix: CSV exports no longer use raw PHP stream handles. * Fix: Uninstall cleanup now uses `WP_Filesystem` and prepared identifiers for the table drop. * Fix: Report queries are cached with the object cache and all table names are passed through `$wpdb->prepare()`. * Fix: Added missing `translators:` comments and prefixed template variables. * Fix: Translations are now loaded automatically by WordPress (removed the discouraged` load_plugin_textdomain()` call). * Compatibility: Requires WordPress 6.2 or newer; tested up to WordPress 7.0. #### 1.1.0 * New: Redesigned front-end shortcode UI with a modern card layout, gradient header and animated result cards. * New: Drag & drop PDF upload zone with a managed, removable file queue and per- file validation. * New: Per-result “Download PDF” and “Download CSV” buttons on the front-end (generated client-side; works for guests too). * New: “Guest uploads” setting to allow logged-out visitors to run the preflight test from the front-end (toggle on/off in the admin). #### 1.0.0 * Initial released version. ## 中繼資料 * 版本 **1.0.0** * 最後更新 **1 週前** * 啟用安裝數 **少於 10 次** * WordPress 版本需求 ** 6.2 或更新版本 ** * 已測試相容的 WordPress 版本 **7.0.3** * PHP 版本需求 ** 7.4 或更新版本 ** * 語言 * [English (US)](https://wordpress.org/plugins/alphaprepress-pdf-preflight/) * 標籤: * [pdf](https://tw.wordpress.org/plugins/tags/pdf/)[preflight](https://tw.wordpress.org/plugins/tags/preflight/) [print](https://tw.wordpress.org/plugins/tags/print/)[woocommerce](https://tw.wordpress.org/plugins/tags/woocommerce/) * [進階檢視](https://tw.wordpress.org/plugins/alphaprepress-pdf-preflight/advanced/) ## 評分 這個項目尚無任何評論記錄。 [Your review](https://wordpress.org/support/plugin/alphaprepress-pdf-preflight/reviews/#new-post) [查看全部使用者評論](https://wordpress.org/support/plugin/alphaprepress-pdf-preflight/reviews/) ## 參與者 * [ alphaprepress ](https://profiles.wordpress.org/alphaprepress/) ## 技術支援 使用者可在技術支援論壇提出意見反應或使用問題。 [檢視技術支援論壇](https://wordpress.org/support/plugin/alphaprepress-pdf-preflight/)
