c# - Rotating An Image using AddTemplate -

using vs 2010, c#, itextsharp

i creating pdf document opening various existing pdf documents, extracting images them , inserting them new pdf document. problem trying rotate images in new pdf document (depending on width , height of source images) make efficient use of space in new pdf document (ultimately used print set of stickers). looking @ output file stickers appear rotating however, right hand end of sticker dissapears out of top of document resulting in image appearing large forward slash / bottom left top of document.

the original code not rotate image (and works perfectly)

the x,y (sourcexstart, sourceystart) co-ordinates of image dynamically calculated

the existing code - no rotation - , works perfectly

if ((sourcexstart + pdfinreader.getpagesizewithrotation(1).width + 10) >= (thepagewidth - 5)) {     sourcexstart = 5;     sourceystart = sourceystart + lastheight + 30;     lastheight = 0; }  cb.addtemplate(page, sourcexstart, sourceystart);  // add image sourcexstart = sourcexstart + pdfinreader.getpagesizewithrotation(1).width + 10; if (pdfinreader.getpagesizewithrotation(1).width > lastheight) { // note maximum height of sticker in row     lastheight = pdfinreader.getpagesizewithrotation(1).width; } 

the new code - attempting rotation 90 degreed depending on width & height

if (pdfinreader.getpagesizewithrotation(1).width < pdfinreader.getpagesizewithrotation(1).height)  // tall stickers { // first need check if image fit in width of page     if ((sourcexstart + pdfinreader.getpagesizewithrotation(1).height + 10) >= (thepagewidth - 5))     {         sourcexstart = 5;         sourceystart = sourceystart + pdfinreader.getpagesizewithrotation(1).width + 30;         lastheight = 0;     }      cb.addtemplate(page, 0, -1f, 1f, sourcexstart, sourceystart,    pdfinreader.getpagesizewithrotation(1).width);     sourcexstart = sourcexstart + pdfinreader.getpagesizewithrotation(1).width + 5;     if (pdfinreader.getpagesizewithrotation(1).width > lastheight)     {         lastheight = pdfinreader.getpagesizewithrotation(1).width;     } }
