c# - How to resize PDF Document to fit a Bitmap -


( using pdf sharp )

i have few bitmaps , each bitmap create new pdf page. problem pdf page not have enough height contain entire bitmap, i'm losing portion of bitmap.

what best way resize pdf page entire bitmap fit 1 pdf page?

  public static pdfdocument getpdf(list<bitmap> pages, bool makefit = false)     {         using (var doc = new pdfdocument())         {             (byte = 0; < pages.count(); i++)             {                 pdfpage opage = new pdfpage();                 doc.pages.add(opage);                  using (var xgr = xgraphics.frompdfpage(opage))                 {                     using (var bm = pages[i])                     {                         using (var img = ximage.fromgdiplusimage(bm))                         {                             xgr.drawimage(img, 0, 0);                         }                     }                 }             }             return doc;         }     }

i did try set size @ location

 xgr.drawimage(img, 0, 0);

but made bitmap larger , not pdf page.

i may need point out concept behind saving bitmaps pdf pages, , give small simple example of how done.

i've looked on of files @ pdf sharp , they're not easy grasp.

i'm hoping can tell me how approach in simplest form. need save bitmap pdf page , make sure bitmap has been saved pdf page viewable.

thank you!!

i've added updated version, snapshot on left of raw .png image being rendered in browser , 1 on right browser rendering pdf.

here updated code:

 public static pdfdocument getpdf(list<bitmap> pages, bool makefit = false)     {         using (var doc = new pdfdocument())         {             (byte = 0; < pages.count(); i++)             {                 pdfpage opage = new pdfpage();                 doc.pages.add(opage);                  if (makefit)                 {                     xsize size = new xsize(pages[i].width, pages[i].height);                     opage.height = size.height;                     opage.width = size.width;                 }                  using (var xgr = xgraphics.frompdfpage(opage))                 {                     using (var bm = pages[i])                     {                         using (var img = ximage.fromgdiplusimage(bm))                         {                             xgr.drawimage(img, 0, 0);                         }                     }                 }             }             return doc;         }     }

what i've done resize pdf page bitmap , drawed bitmap onto page , resize bitmap pdf page size -5px.

      public static pdfdocument getpdf(list<bitmap> pages, bool makefit = false)     {         xsize size = new xsize(0, 0);         using (var doc = new pdfdocument())         {             (byte = 0; < pages.count(); i++)             {                 pdfpage opage = new pdfpage();                 doc.pages.add(opage);                  if (makefit)                 {                     size = new xsize(pages[i].width, pages[i].height);                     opage.height = size.height;                     opage.width = size.width;                 }                  using (var xgr = xgraphics.frompdfpage(opage))                 {                     using (var bm = pages[i])                     {                         using (var img = ximage.fromgdiplusimage(bm))                         {                             if (makefit)                             {                                 xgr.drawimage(img, 0, 0, size.width - 5, size.height - 5);                             }                             else                             {                                 xgr.drawimage(img, 0, 0);                             }                         }                     }                 }             }             return doc;         }     }

perhaps you're looking for: http://www.pdfsharp.net/wiki/pagesizes-sample.ashx

in particular, note @ top: "you can set size of page size using width , height properties."

i.e. 

opage.width = ... opage.height = ...
