This article was previously published under Q148612

SYMPTOMS

When you run the Win32 API "World" programming sample included with Fortran PowerStation version 4.0 under Windows 95 and change the program's horizontal or vertical scaling factors, the displayed metafile isn't redrawn to reflect the new scale factors. The World sample program is located under the topic "Win32: Win32 API Programming with Fortran" in the Samples/Advanced Programming section of Books Online.

CAUSE

The Windows API function SetWorldTransform() used to scale the metafile is not supported under Windows 95. This does not apply to Windows NT version 3.51 or later.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Steps to Reproduce Problem

  1. Using the Infoviewer, select "FPS 4.0 Books Online."
  2. Open the topic "Win32: Win32 API Programming with Fortran." This is located in the Samples/Advanced Programming section of Books Online.
  3. Go to the "World" sample and copy all of its files to your computer's hard disk. To do this, click the World button, and then choose Copy All from the Application Sample dialog box.
  4. Run the World.exe program, and load a metafile into the application client area. From the World Coordinate Transforms main menu, choose Open from the Metafile menu, and then choose the file Sample.emf.
  5. Next, change the graphic scaling factors. From the World Coordinate Transforms main menu, select Scale, and in the Scale Image dialog box, select a new horizontal or veritcal scaling factor. Then click the OK button.
In Windows 95 changing the scaling factors has no effect. However, in Windows NT version 3.51 or higher, the metafile is redrawn to reflect the new scaling factors.
