  startY - top pixel position of the display area in device coordinates

  sizeX - horizontal size (in pixels) for displaying the page

  sizeY - vertical size (in pixels) for displaying the page

  rotate - page orientation: 0 (normal), 1 (rotated 90 degrees clockwise),2 (rotated 180 degrees), 3 (rotated 90 degrees counter-clockwise)

  pageX - X value in page coordinates

  pageY - Y value in page coordinate

  Add commentMore actionsConvert the screen coordinates of a point to page coordinates.The page coordinate system has its origin at the left-bottom cornerof the page, with the X-axis on the bottom going to the right, andthe Y-axis on the left side going up.NOTE: this coordinate system can be altered when you zoom, scroll,or rotate a page, however, a point on the page should always havethe same coordinate values in the page coordinate system.The device coordinate system is device dependent. For screen device,its origin is at the left-top corner of the window. However thisorigin can be altered by the Windows coordinate transformationutilities.You must make sure the start_x, start_y, size_x, size_yand rotate parameters have exactly same values as you used inthe FPDF_RenderPage() function call.

  Parameters:

  doc - pdf document

  pageIndex - index of page

  startX - Left pixel position of the display area in device coordinates.

  startY - Top pixel position of the display area in device coordinates.

  sizeX - Horizontal size (in pixels) for displaying the page.

  sizeY - Vertical size (in pixels) for displaying the page.

  rotate - Page orientation:0 (normal)1 (rotated 90 degrees clockwise)2 (rotated 180 degrees)3 (rotated 90 degrees counter-clockwise)

  deviceX - X value in device coordinates to be converted.

  deviceY - Y value in device coordinates to be converted.
