Tenth post of a series, translated from the "WinDev and PowerBASIC",
to explain the use of GDImage64 in procedural* programming mode with Visual Studio 2022.

About Tutor_10
This tutor introduces the use of an image ruban to create a contact sheet.
It is used to browse images from a gallery folder

Contact sheet
You have to move the mouse cursor to the top of the client area to see it (auto-hide).
Once visible, you can scroll the contact sheet to the left or to the right, by moving the cursor hover the auto-hide arrows.
Click on an icon to display the related image.

Watermak
It is shown on the right corner bottom, when selecting a new image.

Last but not least,
the size of the standalone binary EXE is only 17 Kb.


   
* procedural programming mode, is based on direct use of the FLAT API (Windows SDK) that is the core meat of the OS.

This version has been converted to VS2022, using TCLIB.dll to produce a small 39 Kb ORV64.exe binary.

It uses GDImage64.dll, WinLIFT64.dll, Bass.dll, and ORDLL64.dll that is a small subset of the ObjReader OpenGL 3D engine.

About:
ORDLL64 can be used with any 64-bit language to render wavefront .obj 3D models, using the specific ObjReader materials.
You can select a project from the combobox,
or using drag and drop to play any model downloaded from the 3D collection
(Explorer drag and drop can also be used to play audio files)

The ORDLL64.dll API is using this limited set of functions
OR_CreateWindow(IN DWORD dwExStyle, IN HWND hParent, IN DWORD dwStyle, IN long x, IN long y, IN long w, IN long h, IN HMENU CtrlID);
OR_DetectGPU();
OR_GPUinfo();
OR_About();
OR_ViewReset();
OR_GetAudioVolume();
OR_SetAudioVolume(IN long nVolume);
OR_ProcessCommandLine(IN WCHAR* lpCmdLine);
OR_Vertices();
OR_Triangles();
OR_Indices();
OR_Meshes();
OR_Materials();
OR_ObjSize();
OR_LoadTime();
OR_Version();
OR_TimerEnable(IN BOOL enable);
OR_SetSwapInterval(IN BOOL bUseInterval);
OR_ObjFileName();
OR_GPU();
OR_CPU();
OR_GetAniTick();

This is a rather complex project using several technologies.

• It is a compound application, mixing 64 and 32-bit code,
• WM_COPYDATA, is used to communicate between multiple binary components.
• The main application is 64-bit, while the companion ZWP (ZAP Window Plugin) is 32-bit.
• ZWP is the interface between the high level code, and the low level 32-bit OpenGL visual plugins.
• ZWP is also in charge of processing the audio signal.
• Using RCDATA to create the 32-bit audio DLL (Bass.dll) directly in memory.

DWM compositing

Both WinLIFT and GDImage are able to work in transparent composited mode, using variable opacity.
This is quite obvious when you start the application, before playing audio.

You can move the main window around, however WinLIFT always keep it inside of the WinDows desktop client size.
It does the same when you popup the (info) "About" dialog box, that is constraint inside of the main window client size.
The winLIFT modal info dialog box, is using DDW (Dim Disabled Window) with grayed transparent background until you close it.

About "Let her dance for you"
The central PNG animation is synchronized on the audio signal tempo while playing music.
You can select an audio file from the dedicated combo, or using drag and drop from the Explorer.
While playing music, you can drag the seeker to move forward or backward.
The small rotating gauge located at the bottom right edge allows you to adjust the audio level.
You can change of OpenGL visual plugin, by selecting a new name from the specific combo.
While playing, you can move the cursor to the center of the GDImage control to pause/play music.

WinLIFT controls
All controls are using anchor properties.
The gauges, and the vertical track bar (zoom), can be restored to their default values using a right mouse click.
The Transparent check box, enable or disable full transparency.
The PLAY check box, turn music on/off

I see TCLib.LIB in every tutorial project folder. What is it used for? Where is its header file for calling its functions?

to explain the use of GDImage64 in procedural* programming mode with Visual Studio 2022.

About Tutor_06
This tutor introduces the use of sprite graphic controls to create a CAROUSEL.

To look good, the application is using WinLIFT to skin the project with two lines of code.
See at the end of the CreateControls() procedure

    // Here is the WinLIFT magic
    if (skInitEngine(L"Tutor.sks", NULL)) {
        if (skSkinWindow(hParent, L"  Dock  |  Undock  |  Minimize  |  Maximize  |  Restore  |  Close  ")) {
            // If hParent has been skinned with success,
            // then update its minimum track size using WinLIFT metrics.
            RECT r; GetWindowRect(hParent, &r);
            MinTrackSizeW(rWidth(r));
            MinTrackSizeH(rHeight(r));
        }
    }


More about this in the WinLIFT section.

This project is using GDImage64 version 7.12, if ever you want to load the sprites from resource rather than disk file.

Last but not least,
the size of the standalone binary EXE is only 19 Kb.
