# PDF import function optimization (PDFIMPORT) [GstarCAD 2027](Help%20System/GSTARCAD/2027/Index.md) → [What's new](Help%20System/GSTARCAD/2027/What's%20new/(What's%20new).md) GstarCAD 2026 replaced the underlying library and the corresponding import interface, optimized the import efficiency and solved the legacy PDF import problems. ## The main problems solved include the following: 1. Optimized the PDF import rendering effect on the raster image. Mainly transparency channel (background image), image clarity, image color difference; 2. Imported text type changed to multi-line text. Optimized recognition logic to identify text in the same line as a single multiline text entity, facilitating easier editing for users; 3. Imported text to join the width factor logic. The width factor of the first imported character will be applied uniformly; 4. Text decoding problems. Solved the problem of some text garbled; 5. Optimized the display effect of the fill; 6. Improved the processing speed of import. --- [Original help](https://www.gstarcad.net/help/GstarCAD_2027_en-US/detail/GstarCAD2026NEW/GUG_NewFunction2026_PDFimportbaselibraryupdate.html) · © Gstarsoft Co., Ltd.
