GDI Calls May Nay Work With Very Large Coordinates (299533)

SYMPTOMS

• The Software Development Kit (SDK) documentation incorrectly states that coordinate spaces for devices are limited to 2^27 units high (0x8000000) by 2^27 units wide (0x8000000). The actual limits are 2^26 (0x4000000). The GetLastError function typically returns error 534 (ERROR_ARITHMETIC_OVERFLOW) when these limits are exceeded.
  
  Programs that are most likely to exceed the coordinate limits are those programs that have large scrollable windows, that use multiple-pixel-wide pens with GDI primitives (such as those that are used to draw lines, rectangles, arcs, ellipses, and so on).
• A GDI call may not work because there is an internal error. When this occurs, the GetLastError function returns error 8 (ERROR_NOT_ENOUGH_MEMORY). This article describes how to update your computer to fix this problem.
  
  This problem affects, but is not limited to, Windows GDI functions such as LineTo and Rectangle. For example, if a GDI program runs code that is similar to the following code by using a tow-pixel-wide pen, the LineTo function may not work:

  MoveToEx(hDC, 10, 10, NULL);
  LineTo(hDC, 10, 65000000);
