Short: application layer for pixel graphics
Author: Timm S. Müller
Uploader: Timm S. Müller (bifat@neoscientists.org)
Type: dev/misc
Version: 17.1
Requires: Kickstart 3.0 (v39), MC68020, render.library v30
overview
-----------------------------
- guigfx.library is an application layer for pixel graphics.
- guigfx.library breaks the chains of all those nasty
planar, chunky, 8/16/24bit, OS3.0, OS3.1, OCS, ECS, AGA,
CybergraphX and Picasso96 considerations.
- with guigfx.library you no longer have to take care about your
application running on a OCS machine or on a high-end
graphics-card system.
- guigfx.library lets you freely choose truecolor graphics for
your applications.
- with guigfx.library your graphics will always look as fine as
possible, on any screen, no matter if driven on 24 bit
1024x768 CybergraphX/Picasso96, on HAM8, or 1 bit productivity
interlaced.
- guigfx.library does quick color-reduction, rendering,
remapping and dithering for you. only you don't know when,
on which machine, under what circumstances.
- guigfx.library treats scaling as a standard operation.
it is available at any time, without extra consideration,
without extra memory consumption, even without a true loss
of performance.
- guigfx.library handles screen pen allocation in an extremely
effective way.
- guigfx.library hides bugs, incompatibilities and insufficiencies
of graphics.library, cybergraphics.library and Picasso96 from
you. it is an attempt to render incompatibilities between
different versions of CybergraphX and Picasso96 obsolete.
- guigfx.library features picture.datatype import. standard and
v43 (including Picasso96) picture datatypes are automatically
recognized and used as available.
- guigfx.library does not call SetFunction() and is hereby
guaranteed to never do so in future versions.
- guigfx.library puts all that stuff into a black-box,
freeing your mind for the creative part.

recent changes
-----------------------------
v17.1
- added an internal hook delay counter. user hooks
are now called less frequently during scaling/rendering,
which gives a slight performance boost in some
applications
- guigfx.library no longer loses memory upon open/close.
this leak was present for eons. fixing it caused the library
itself to shrink by several kilobytes of useless object
code. no, i won't tell more details about this #*&%! one :-)
- removed the examples from the distribution because they were
everything but instructive.
v17
- bug fixed: the drawhandle's autodither attribute
was not considered in CreatePictureBitMap().
- added GGFX_AutoDither tag for CreatePictureBitMap()
for overriding the drawhandle's autodither tag.
v16.4
- reconstructed 16.3 changes after a minor HD desaster
v16.3
- bug fixed in LoadPicture(): GGFX_UseMask was broken.
memory for an alphachannel/mask was always allocated
when there was a transparency color inside the picture,
regardless of the GGFX_UseMask attribute. now an
alphachannel is only allocated when both GGFX_UseMask
is set and a mask is actually present.
- added documentation for a feature that was present
and considered experimental since v8.3: drawing with
rotating/texture-mapping in a single pass, without
additional buffers. see: ObtainDrawHandle()/GGFX_BGColor
and DrawPicture()/RND_DestCoordinates.
