Overview:

Features:

• 48-bit Protected Mode support
• Access to double buffers as large as 32768x4096
• Fully object oriented access to graphics buffers
• VBE 1.2, 2.0 and 3.0 compliant
• Transparent support for a linear frame buffer (LFB) when available
• Blindingly fast graphics primitives, most of which are faster than the ones produced by SciTech, VirTech, and FastGraph. Also noticably faster than TMT Pascal's Graph unit. You can download an example of ours versus theirs in the Demo/Games section. ObjGfx also recently won in a taste test against them.
• Support for any 8/15/16bpp modes, including unstandard resolutions such as 400x300 or 512x384.
• Generic loading and saving of graphic files including: PCX, MSH, DNY
• The fastest transparent image (blit) support of any graphics library in existence (Blits are not compiled sprites)
• Highly optimized bitmap routines specifically designed for games and/or graphical user interfaces (GUIs).
• General clipping of all but three routines (GetImage, PutImage, and PutBlit do not yet clip)
• Runs under Dos, Windows 3.1x, Windows 95, and Windows 98
• Contains NewFrontier, a unit that allows the allocation of pointers larger than 64K.
• Contains Keys, a unit that contains functions that behave identically to the readkey and keypressed functions in the CRT unit. It also allows an alternate keyboard handler which allows detection of multiple keypresses.

New changes in ObjGfx 2.0

• ObjGfx is now called ObjGfx8, denoting that it is an 8bpp graphics library. There is a new unit called ObjGfx0 which contains a majority of data types and structures. Add ObjGfx0 to your Uses clause if the compiler complains about an unknown symbol.
• There is no longer a Vesa8 type. It is now called TScreen8. If you want a pointer to TScreen8 object use PScreen8.
• There is no longer a Gfx8 type. It is now called TGfx8. If you want a pointer to a TGfx8 object use PGfx8.
• The ordering of variables in the objects has changed. Please see ObjGfx8.ASM for the new structure.
• The maximum number of scanlines in an object is 4096.
• WhatType() has been renamed to WhatType8().
• ModeIsAvailable() has been renamed to IsModeAvailable().
• GetBlit now accepts a pointer48 instead of a selector as the buffer to put the blit in.
  
  Here is an example of the old way:
  
  Buf.GetBlit(x1,y1,x2,y2,Selector);
  
  Here is the new way:
  
  Buf.GetBlit(x1,y1,x2,y2,ptr48(Selector,0));
  
  This will allow you to dump multiple blits in the same buffer assuming that you have pre-calculated the space required.
• AliasGfx8 no longer uses relative coords (ie, StartX, StartY, width, height). It now uses absolute coords (ie, x1,y1,x2,y2).
  
  Here is an example of the old way:
  
  {Alias a 320x200 section starting at 50,50}
  Buf2.AliasGfx8(Buf1,50,50,320,200);
  
  This is the new way:
  
  {Alias a 320x200 section starting at 50,50}
  Buf2.AliasGfx8(Buf1,50,50,369,249);
