Hi, Using PDF Library.. For first time, PDF page rotates for 90 deg, After that page is not getting rotated further by 90 deg. Here is code: QP.SetOrigin(1); QP.SelectPage(1); if(nRotateType == c_eventRotate90) //Clock wise QP.RotatePage(90); else if(nRotateType == c_eventRotate270) //Anti clockwise QP.RotatePage(270); if((nRotateType == c_eventRotate90) || (nRotateType == c_eventRotate270)) QP.SaveToFile(image_puForeign->acPathTemp); //It saves rotated page.. QP.RenderPageToDC(g_dpdfDPI, g_nCurrentPage,hdc); Please let me know the solution Narayana Reddy.L |

Hi Lakkan, "rotate 90" don't rotate the page and save it rotated. "rotate 90" means for the pdf reader that the document shall be displayed with a rotation of 90 degrees. So if you insert a second "rotate 90" nothing more will happen. If you want to add 90 degrees you have to add these 90 to the existing 90 -> "rotate 180". Cheers, Ingo ------------- Cheers, Ingo |

If you perform a NormalizePage 0 after the RotatePage, the results will be what you expect. NormalizePage has the effect of saving the new orientation of the page. |
