MiGS Overview -
A Minimalist Graphics Subsystem -

-

- -

-Introduction

- -
This document details the design and implementation of MiGS, -the minimalist graphics subsystem used by the FreeType 2 demonstration -programs. Its purpose is mainly to help writers of new demo programs, as -well as developers who would like port the subsystem to other platforms.
- -
-

-I - Design goals

- -
MiGS is a tiny graphics subsystem used to demo text rendering -through the FreeType library. It was mainly written to provide the abilities -to :
- -
    -
      -
    • -draw a monochrome glyph bitmap to many kinds of target surfaces (i.e. really -bitmaps/pixmaps)
      • - -
    • -draw an anti-aliased glyph bitmap, with any level of grays, to many kinds -of target surfaces
      • - -
    • -display a simple window on many systems like X11, OS/2 and Windows
      • - -
    • -accept simple events (keypresses and mouse buttons) in this window.
      • - -
    • -to be portable and present a unified API on all running systems
      • -
    - -


    MiGS uses system-specific "drivers" in order to perform display -and event handling. The blitting functions are not device-specific. MiGS -can be built and/or used with no system-specific features, like for example, -to generate simple GIF, PNG, TIFF, etc.. images without ever needing to -display them.

- -

- -

- -

-II - Surfaces, bitmaps and windows

- -
A surface in MiGS models a drawable region where glyph images -can be rendered, a surface always contains a bitmap descriptor as well -as a few other things that will be described later in this section. -

Some surfaces can be displayed, they are then either called windowed -surfaces or screen surfaces depending on the nature of the device -used to display them. Each device is implemented by a very simple -driver in the MiGS code. Here are a few example devices that are -or could be written to display surfaces : -

- an X11 device -
- a Win 32 GDI device -
- an OS/2 Presentation Manager device -
- a fullscreen SVGALib device on Linux -
- a GGI visual device -
- an OS/2 "Dive" device, or the equivalent Win32 "DirectX" device -

etc.. -

NOTE: For now, only the X11 device was written and tested.. More -devices should come later -

Before explaining how to create a surface, we need to explain how MiGS -manages bitmaps and renders glyph images to them. -

-1. Bitmaps :

- -
A bitmap in MiGS features the following things : -
    -
  • -a width in pixels
    • - -
  • -a height in pixels
    • - -
  • -a pixel mode, which indicates how the pixels are stored in -the surface's buffer
    • - -
  • -a pitch, whose absolute values is the number of bytes taken -by each surface row
    • - -
  • -a number of valid gray levels (see below)
    • - -
  • -a buffer, holding the surface's pixels
    • -
- -


MiGS uses the "Y downwards" convention, which means that -increasing -Y coordinates correspond to lower rows of the bitmap. Hence, -the coordinate (0,0) always corresponds to the bitmap's -top-left -pixel. -

The bitmap's rows can be stored either "downwards" or "upwards" -in the pixel buffer. -

In the first case (downwards), increasing memory addresses in -the pixel buffer correspond to lower rows of the bitmap(e.g. PC video modes), -and the pitch should be equal to the number of bytes -taken by each row. The first pixel buffer byte corresponds to the -upper row. -

In the second case (upwards), increasing memory addresses in -the pixel buffer correspond to upper rows of the bitmap and the pitch -should be equal to the opposite of the number of bytes -taken by each row. The first pixel buffer byte corresponds to the lower -row. -

In all cases, the pitch is the increment to be used -to go from one bitmap row to the one below it. -

The supported pixel modes are : -

    -
  • -1-bit monochrome bitmaps. With "0" as the background, and "1" as the foreground.
    • - -
  • -4-bit color bitmaps, using an arbitrary palette.
    • - -
  • -8-bit color bitmaps, using an arbitrary palette.
    • - -
  • -8-bit gray bitmaps, using a given N number of gray levels in the range -0..N-1.
    • - -
  • -15-bit color bitmaps, also known as RGB555
    • - -
  • -16-bit color bitmaps, also known as RGB565
    • - -
  • -24-bit color bitmaps, also known as RGB
    • - -
  • -32-bit color bitmaps, also known as RGBA (though the A is ignored by MiGS)
    • -
-The bitmap's number of gray levels is only relevant for 8-bit -gray bitmaps, and indicates the range of gray levels that can be -found in the bitmap. If a bitmap as N gray levels, it is said to be N-grayscales, -and the pixels within it must all have values between 0, considered as -the background color, and N-1, considered as the foreground -color. -

N-grayscale bitmaps are crucial for the rendering of anti-aliased text. -
 

- -

-2. Glyph images :

- -
The glyph images that can be drawn on bitmaps through MiGS -are bitmaps themselves, though limited to the following pixel modes : -

1-bit monochrome glyph bitmaps -

These can be drawn on any kind of bitmap. Note that only -the "lit" pixels (i.e. the bits set to 1) are effectively drawn to -the target, as opaque blitting isn't supported (remember, it's a minimalist -library !)
- -


N-grayscales glyph images (with any value of N >= 2) -

These can be drawn to all RGB bitmaps (15, 16, 24 & -32 bits/pixel), as well as any other M-grayscales bitmaps. In the latter -case, the values of N and M need not be equal, as the library is -able to perform automatic conversions on the fly. -

For example, it is possible to render a 5-grayscales glyph image into -a 128-grayscales bitmap. Moreover, it is also possible to render a 17-grayscales -glyph image into a 5-grayscales bitmap, even if this will result in a -loss of quality. This feature is crucial in order to experiment easily -with other anti-aliasing algorithms for FreeType -
 

-Note that you can only draw monochrome bitmaps to the following -pixel modes : monochrome, 4-bit color and 8-bit color.
- -

-3. Windows and Screens:

- -
In order to debug FreeType, displaying a surface in a window -or in full-screen mode, is required. MiGS thus makes a difference between -simple -surfaces, which only contain a bitmap, windowed surfaces, which -are used to display their content in a window, and screen surfaces, -which are used to display their content in a full-screen mode (SVGAlib, -DirectX, GGI or wathever). -

A few important things must be said about non-simple surfaces. -
  -

    -
  • -First, they might contain some system-specific data which is used to manage -the display in a window or on the screen. This must be completely hidden -to MiGS clients. Indeed, rendering to any kind of surface is achieved through -exactly -the same function calls.
    • -
- -
    -
  • -Second, they may contain a bitmap whose pixel mode doesn't correspond to -the screen's depth used to display it. For example, the surface might contain -an 128-grayscale bitmap, while the screen is in RGB24 mode. Some conversion -must be performed to display the surface. This can either happen in the -system-specific graphics library (e.g. on OS/2, a single Presentation Manager -call is used to blit a N-grayscale image to any kind of window) -or in the system-specific part of MiGS (e.g. the X11 MiGS driver must convert -the surface's bitmap into the appropriate X11 image each time a -repaint is requested). Again this must be completely hidden to MiGS clients
    • -
-Surfaces have also a few fields that are only used when displaying them -in Windows : -

a title string -

This is simply a text string that is displayed on the title -bar of the surface's window. It can also appear at the top or bottom of -full-screen surfaces if the MiGS driver supports it. The title string can -be changed with a call to grSetTitle, and is ignored for simple -surfaces.
- -


a refresh flag -

This boolean flag is only used for window surfaces, and some -fullscreen ones (depending on the driver implementation). When set, it -indicates that each glyph image blit must be displayed immediately. By -default, this flag is set to False, which means that demo programs must -call the grRefreshSurface(surface) function to display the whole -contents of a surface one it has been updated. -

The refresh flag can be set with grSetSurfaceRefresh(surface,flag). -Note that a single surface rectangle can be forced to be displayed with -a call to grRefreshRectangle(surface,x,y,w,h) at any time.

-
- -

-4. Devices :

- -
As said before, each device is in charge of displaying a surface -in a given window or screen. Each device is managed through a very simple -driver, described to MiGS through a very simple "grDevice" structure. -

A grDevice contains, among other things, pointers to the functions used -to: -

- refresh/display a given rectangle of the surface to the window/screen -
- listen events (key presses and mouse) and send them back to client -apps. -
- for windowed devices, update the title bar. -

As said before, this is a highly minimalist system.. -
 

-
- -
-

-III - Important implementation issues :

- -
-

-1. Display surface negociation :

- -
A display surface is created with the function grNewScreenSurface -which takes parameters indicating which device should be used, the pixel -dimensions of the requested surface, as well as its pixel mode. -

Because of some device-specific limitations, the resulting surface's -properties might not match exactly those requested for the call. Hence, -a developper should always take care of reading a new display surface's -bitmap descriptor in order to get its real dimensions, pixel -mode and eventually number of grays. -

The function grNewSurface will create a memory surface with the corresponding -bitmap. -
The function grNewBitmapSurface will create a surface from a pre-existing -bitmap. This is useful to draw text on loaded images, for example. -

Any surface (display or not) is destroyed with grDoneSurface.

- -

-

- -

-2. Supporting 8-bit grayscale mode :

- -
It is important, for the debugging of FreeType anti-aliased -renderer(s), that _all_ devices should support the 8-bit gray mode. -The number of gray levels can be fixed or negociated as required by implementation-specific -issues. -

As most existing devices do not provide direct support for such a mode, -each 8-bit surface must thus contain : -

- an internal N-grayscale bitmap, used as the target of all glyph drawings -
- its own device-specific "image", which matches the display depth. -

Each time the device's "refresh_rect" function is called, it should -then : -
- convert the grayscales within the bitmap's rectangle into the image's -buffer and format. -
- display the corresponding image rectangle. -

This scheme is used, for example, by the X11 device.

The 'GpiBlitBlt' only works with presentation - * spaces. This means that we also need to create, for each surface : - * - * - a memory presentation space, used to hold the PM bitmap - * - a "memory device context" for the presentation space - * - * The blit is then performed from the memory presentation space - * to the screen's presentation space.. - * - * - * - because each surface creates its own event-handling thread, - * we must protect the surface's presentation space from concurrent - * accesses (i.e. calls to 'GpiSetBitmapBits' when drawing to the - * surface, and calls to 'GpiBlitBlt' when drawing it on the screen - * are performed in two different threads). - * - * we use a simple mutex to do this. - * - * - * - we also use a semaphore to perform a rendez-vous between the - * main and event-handling threads (needed in "listen_event"). - * - ************************************************************************/ - - static - void RunPMWindow( grPMSurface* surface ); - - - - - static - void refresh_rectangle( grPMSurface* surface, - int x, - int y, - int w, - int h ) - { - LOG(( "Os2PM: refresh_rectangle( %08lx, %d, %d, %d, %d )\n", - (long)surface, x, y, w, h )); - - (void)x; - (void)y; - (void)w; - (void)h; - - /* - convert_rectangle( surface, x, y, w, h ); - */ - DosRequestMutexSem( surface->image_lock, SEM_INDEFINITE_WAIT ); - GpiSetBitmapBits( surface->image_ps, - 0, - surface->root.bitmap.rows, - surface->root.bitmap.buffer, - surface->bitmap_header ); - DosReleaseMutexSem( surface->image_lock ); - - WinInvalidateRect( surface->client_window, NULL, FALSE ); - WinUpdateWindow( surface->frame_window ); - } - - - static - void set_title( grPMSurface* surface, - const char* title ) - { - ULONG rc; - -#if 1 - LOG(( "Os2PM: set_title( %08lx == %08lx, %s )\n", - (long)surface, surface->client_window, title )); -#endif - LOG(( " -- frame = %08lx\n", - (long)surface->frame_window )); - - LOG(( " -- client parent = %08lx\n", - (long)WinQueryWindow( surface->client_window, QW_PARENT ) )); - - rc = WinSetWindowText( surface->client_window, (PSZ)title ); - LOG(( " -- returned rc = %ld\n",rc )); - } - - - - static - void listen_event( grPMSurface* surface, - int event_mask, - grEvent* grevent ) - { - ULONG ulRequestCount; - - (void) event_mask; /* ignored for now */ - - /* the listen_event function blocks until there is an event to process */ - DosWaitEventSem( surface->event_lock, SEM_INDEFINITE_WAIT ); - DosQueryEventSem( surface->event_lock, &ulRequestCount ); - *grevent = surface->event; - DosResetEventSem( surface->event_lock, &ulRequestCount ); - - return; - } - - - static - grPMSurface* init_surface( grPMSurface* surface, - grBitmap* bitmap ) - { - PBITMAPINFO2 bit; - SIZEL sizl = { 0, 0 }; - LONG palette[256]; - - LOG(( "Os2PM: init_surface( %08lx, %08lx )\n", - (long)surface, (long)bitmap )); - - LOG(( " -- input bitmap =\n" )); - LOG(( " -- mode = %d\n", bitmap->mode )); - LOG(( " -- grays = %d\n", bitmap->grays )); - LOG(( " -- width = %d\n", bitmap->width )); - LOG(( " -- height = %d\n", bitmap->rows )); - - /* create the bitmap - under OS/2, we support all modes as PM */ - /* handles all conversions automatically.. */ - if ( grNewBitmap( bitmap->mode, - bitmap->grays, - bitmap->width, - bitmap->rows, - bitmap ) ) - return 0; - - LOG(( " -- output bitmap =\n" )); - LOG(( " -- mode = %d\n", bitmap->mode )); - LOG(( " -- grays = %d\n", bitmap->grays )); - LOG(( " -- width = %d\n", bitmap->width )); - LOG(( " -- height = %d\n", bitmap->rows )); - - bitmap->pitch = -bitmap->pitch; - surface->root.bitmap = *bitmap; - - /* create the image and event lock */ - DosCreateEventSem( NULL, &surface->event_lock, 0, TRUE ); - DosCreateMutexSem( NULL, &surface->image_lock, 0, FALSE ); - - /* create the image's presentation space */ - surface->image_dc = DevOpenDC( gr_anchor, - OD_MEMORY, (PSZ)"*", 0L, 0L, 0L ); - - surface->image_ps = GpiCreatePS( gr_anchor, - surface->image_dc, - &sizl, - PU_PELS | GPIT_MICRO | - GPIA_ASSOC | GPIF_DEFAULT ); - - GpiSetBackMix( surface->image_ps, BM_OVERPAINT ); - - /* create the image's PM bitmap */ - bit = (PBITMAPINFO2)grAlloc( sizeof(BITMAPINFO2) + 256*sizeof(RGB2) ); - surface->bitmap_header = bit; - - bit->cbFix = sizeof( BITMAPINFOHEADER2 ); - bit->cx = surface->root.bitmap.width; - bit->cy = surface->root.bitmap.rows; - bit->cPlanes = 1; - - bit->argbColor[0].bBlue = 255; - bit->argbColor[0].bGreen = 0; - bit->argbColor[0].bRed = 0; - - bit->argbColor[1].bBlue = 0; - bit->argbColor[1].bGreen = 255; - bit->argbColor[1].bRed = 0; - - bit->cBitCount = (bitmap->mode == gr_pixel_mode_gray ?
