The information in this article applies to:
  • Microsoft Windows Software Development Kit (SDK) for Windows version 3.1

SUMMARY

This article discusses basic palette awareness---what it takes for an application to use palettes correctly in the Microsoft Windows graphical environment---by covering these areas:

  • Responding to palette-related messages
  • Managing palette-based bitmaps
  • Managing multiple palettes in one application
  • Using the Clipboard with palettes

MORE INFORMATION

The reader should be familiar with basic palette use for painting operations. This article is not about the Palette Manager, and the level of detail is limited to the very basics of the palette managing process. A sample application, MULTIPAL, is included on the Microsoft Developer Network CD to illustrate the use of multiple palettes in a single application.

MULTIPAL is also included with the PALAWARE technical article located in the Microsoft Software Library.

Download PALAWARE.EXE, a self-extracting file, from the Microsoft Software Library (MSL) on the following services:

  • Microsoft Download Service (MSDL) 

          Dial (206) 936-6735 to connect to MSDL
      Download PALAWARE.EXE (size: 55148 bytes)
  • Internet (anonymous FTP) 

          ftp ftp.microsoft.com
      Change to the \SOFTLIB\MSLFILES directory
      Get PALAWARE.EXE (size: 55148 bytes)

MULTIPAL is a multiple document interface (MDI) extension to the DIBIT sample program that accompanies the "Using DIBs with Palettes" technical article. MULTIPAL allows you to display multiple DIBs with multiple palettes and handles palette messaging from both the system perspective and the application perspective. The MDI skeleton is taken from the BLANDMDI program that is included in the Microsoft(R) Windows(TM) version 3.1 Software Development Kit (SDK). MULTIPAL achieves device independence by using palettes at all times, regardless of the type of device being used.

To see the application in action, open several color-intensive 8-bit device-independent bitmaps (DIBs) at the same time and change the active DIB window. To see the application's interaction with the rest of the system, run another application that uses palettes (another instance of MULTIPAL will do).
