// PictureEx.cpp: implementation of the CPictureEx class.
//
// Picture displaying control with support for the following formats:
// GIF (including animated GIF87a and GIF89a), JPEG, BMP, WMF, ICO, CUR
//
// Written by Oleg Bykov (oleg_bykoff@rsdn.ru)
// Copyright (c) 2001
//
// To use CPictureEx, follow these steps:
// - place a static control on your dialog (either a text or a bitmap)
// - change its identifier to something else (e.g. IDC_MYPIC)
// - associate a CStatic with it using ClassWizard
// - in your dialog's header file replace CStatic with CPictureEx
// (don't forget to #include "PictureEx.h" and add
// PictureEx.h and PictureEx.cpp to your project)
// - call one of the overloaded CPictureEx::Load() functions somewhere
// (OnInitDialog is a good place to start)
// - if the preceding Load() succeeded call Draw()
//
// You can also add the control by defining a member variable of type
// CPictureEx, calling CPictureEx::Create (derived from CStatic), then
// CPictureEx::Load and CPictureEx::Draw.
//
// By default, the control initializes its background to COLOR_3DFACE
// (see CPictureEx::PrepareDC()). You can change the background by
// calling CPictureEx::SetBkColor(COLORREF) after CPictureEx::Load().
//
// I decided to leave in the class the functions to write separate frames from
// animated GIF to disk. If you want to use them, uncomment #define GIF_TRACING
// and an appropriate section in CPictureEx::Load(HGLOBAL, DWORD). These functions
// won't be compiled and linked to your project unless you uncomment #define GIF_TRACING,
// so you don't have to worry.
//
// Warning: this code hasn't been subject to a heavy testing, so
// use it on your own risk. The author accepts no liability for the
// possible damage caused by this code.
//
// Version 1.0 7 Aug 2001
// Initial release
//
// Version 1.1 6 Sept 2001
// ATL version of the class
//
// Version 1.2 14 Oct 2001
// - Fixed a problem with loading GIFs from resources
// in MFC-version of the class for multi-modules apps.
// Thanks to Ruben Avila-Carretero for finding this out.
//
// - Got rid of waitable timer in ThreadAnimation()
// Now CPictureEx[Wnd] works in Win95 too.
// Thanks to Alex Egiazarov and Wayne King for the idea.
//
// - Fixed a visual glitch of using SetBkColor.
// Thanks to Kwangjin Lee for finding this out.
//
// Version 1.3 10 Nov 2001
// - Fixed a DC leak. One DC leaked per each UnLoad()
// (forgot to put a ReleaseDC() in the end of
// CPictureExWnd::PrepareDC() function).
//
// - Now it is possible to set a clipping rectangle using
// CPictureEx[Wnd]::SetPaintRect(const LPRECT) function.
// The LPRECT parameter tells the class what portion of
// a picture should it display. If the clipping rect is
// not set, the whole picture is shown.
// Thanks to Fabrice Rodriguez for the idea.
//
// - Added support for Stop/Draw. Now you can Stop() an
// animated GIF, then Draw() it again, it will continue
// animation from the frame it was stopped on. You can
// also know if a GIF is currently playing with the
// IsPlaying() function.
//
// - Got rid of math.h and made m_bExitThread volatile.
// Thanks to Piotr Sawicki for the suggestion.
