I create a bitmap that is 2550 w x 3300 height which is  8.5 x 11 at 300 dpi

Is there anyway to change the hdc xres and yres to reflect that it is 300 dpi instead of
96 dpi? 

Sample idea of what I am trying to do

L_CreateBitmap RTF_LBMH, 1, PageWP, PageHP, 24, 1, 0, 0, 0, 0
L_FillBitmap RTF_LBMH, RGB(255, 255, 255)
  Do
    RTF_hDC = L_CreateLeadDC(RTF_LBMH)
  Loop Until RTF_hDC <> 0

 FORMATRANGE.rectRegion = RectDrawTo       ' Area on page to draw to
 FORMATRANGE.RectPage = RectPage           ' Entire size of page
 FORMATRANGE.mCharRange.firstChar = StartChar      ' Start of text
 FORMATRANGE.mCharRange.lastChar = EndChar      ' End of the text
 Debug.Print "start end", StartChar, EndChar
 SendMessage RTB.hwnd, EM_FORMATRANGE, 1, FORMATRANGE

The resolution of the created LEAD DC depends on the display settings.
To change it, you will have to change the system font size from the advanced dialog of the Windows display properties.

However, this DPI value might be significant in many cases, because the
actual number of pixels in the image does not depend on it. It always depends on the width and height of the bitmap itself.
