<p>The glBitmap is a Delphi/FPC unit that contains several wrapper classes to manage OpenGL texture objects. Below you can find a list of the main functionality of this classes: - load texture data from file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - load texture data from several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - save texture data to file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - save texture data to several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - support for many texture formats (e.g. RGB8, BGR8, RGBA8, BGRA8, ...) - manage texture properties (e.g. Filter, Clamp, Mipmap, ...) - upload texture data to video card - download texture data from video card - manipulate texture data (e.g. add alpha, remove alpha, convert to other format, switch RGB, ...)</p></td>

<p>The glBitmap is a Delphi/FPC unit that contains several wrapper classes to manage OpenGL texture objects. Below you can find a list of the main functionality of this classes: - load texture data from file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - load texture data from several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - save texture data to file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - save texture data to several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - support for many texture formats (e.g. RGB8, BGR8, RGBA8, BGRA8, ...) - manage texture properties (e.g. Filter, Clamp, Mipmap, ...) - upload texture data to video card - download texture data from video card - manipulate texture data (e.g. add alpha, remove alpha, convert to other format, switch RGB, ...)</p>

<p>The glBitmap is a Delphi/FPC unit that contains several wrapper classes to manage OpenGL texture objects. Below you can find a list of the main functionality of this classes: - load texture data from file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - load texture data from several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - save texture data to file (e.g. BMP, TGA, DDS, PNG, JPEG, ...) - save texture data to several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface) - support for many texture formats (e.g. RGB8, BGR8, RGBA8, BGRA8, ...) - manage texture properties (e.g. Filter, Clamp, Mipmap, ...) - upload texture data to video card - download texture data from video card - manipulate texture data (e.g. add alpha, remove alpha, convert to other format, switch RGB, ...)</p></td>

------------------------------------------------------------
The glBitmap is a Delphi/FPC unit that contains several wrapper classes
to manage OpenGL texture objects. Below you can find a list of the main
functionality of this classes:
- load texture data from file (e.g. BMP, TGA, DDS, PNG, JPEG, ...)
- load texture data from several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface)
- save texture data to file (e.g. BMP, TGA, DDS, PNG, JPEG, ...)
- save texture data to several other image objects (e.g. TBitmap, TLazIntfImage, SDL Surface)
- support for many texture formats (e.g. RGB8, BGR8, RGBA8, BGRA8, ...)
- manage texture properties (e.g. Filter, Clamp, Mipmap, ...)
- upload texture data to video card
- download texture data from video card
- manipulate texture data (e.g. add alpha, remove alpha, convert to other format, switch RGB, ...)
------------------------------------------------------------
History
20-11-2013
- refactoring of the complete library
- glBitmap is managed by git, so this history is not maintenanced any longer
21-03-2010
- The define GLB_DELPHI dosn't check versions anymore. If you say you are using delphi
then it's your problem if that isn't true. This prevents the unit for incompatibility
with newer versions of Delphi.
- Problems with D2009+ resolved (Thanks noeska and all i forgot)
- GetPixel isn't set if you are loading textures inside the constructor (Thanks Wilson)
10-08-2008
- AddAlphaFromglBitmap used the custom pointer instead the imagedatapointer (Thanks Wilson)
- Additional Datapointer for functioninterface now has the name CustomData
24-07-2008
- AssigneAlphaToBitmap overwrites his own palette (Thanks Wilson)
- If you load an texture from an file the property Filename will be set to the name of the file
- Three new properties to attach custom data to the Texture objects
- CustomName (free for use string)
- CustomNameW (free for use widestring)
- CustomDataPointer (free for use pointer to attach other objects or complex structures)
27-05-2008
- RLE TGAs loaded much faster
26-05-2008
- fixed some problem with reading RLE TGAs.
21-05-2008
- function clone now only copys data if it's assigned and now it also copies the ID
- it seems that lazarus dont like comments in comments.
01-05-2008
- It's possible to set the id of the texture
- define GLB_NO_NATIVE_GL deactivated by default
27-04-2008
- Now supports the following libraries
- SDL and SDL_image
- libPNG
- libJPEG
- Linux compatibillity via free pascal compatibility (delphi sources optional)
- BMPs now loaded manuel
- Large restructuring
- Property DataPtr now has the name Data
- Functions are more flexible between RGB(A) and BGR(A). RGB can be saved as Bitmap and will be saved as BGR
- Unused Depth removed
- Function FreeData to freeing image data added
24-10-2007
- ImageID flag of TGAs was ignored. (Thanks Zwoetzen)
15-11-2006
- Function SetBorderColor implemented (only used by opengl if wrap is set to GL_CLAMP_TO_BORDER)
- Function AddAlphaFromValue implemented to use an fixed Value as Alphachannel
- Function ReadOpenGLExtension is now only intern
29-06-2006
- pngimage now disabled by default like all other versions.
26-06-2006
- Setting up an anisotropic filter of 0 isnt allowed by nvidia (Thanks Ogridi)
22-06-2006
- Fixed some Problem with Delphi 5
- Now uses the newest version of pngimage. Makes saving pngs much easier.
