Short: Cybergraphics V3 Update V41.69f
Author: F.Mariak@phase5.de (Frank Mariak)
Uploader: aminet@ufoo.phase5.de (Aminet Uploader)
Type: biz/p5
Update revision history for archive rev 69f
cgxsystem.library
=================
Changes for 41.17 (r69f archive)
- fixed a long outstanding bug in the display mode installation code for
OS 3.1. This bug could lead to loss of AGA/ECS mode monitor IDs when
multiple graphics cards were installed in the system.
- cgxsystem.library.ppc now falls back into 040/060 mode if ppc.library
can not be found.
- FillPixelArray()/cybergraphics does not trash register D2 anymore when
rendering to a non layered rastport
ADDITIONAL NOTE: If you experience any problems with cgxsystem.library.ppc
please try the .040 version first to check if it solves your trouble
before reporting any bugs.
Changes for 41.16 (r69e archive)
- changed behaviour of custom bitmap support code for OpenScreenTagList()/
intuition introduced in 41.15. This should fix some problems with programs
like Resource or CyberView which pass a custom bitmap to OpenScreenTagList()
- added CyberGraphX support for AllocScreenBuffer()/ChangeScreenBuffer()/
FreeScreenBuffer() intuition calls
- GetBitMapAttr(bm,BMA_FLAGS)/graphics now sets the BMF_DISPLAYABLE flag
for CyberGraphX displayable bitmaps
- fixed some problems in DrawEllipse()/graphics with overlapping pixels in
complement drawing mode
- OpenScreenTagList()/intuition cleared the SA_ErrorCode long field in some
cases although the screen was not opened properly. (-> e.g. CygnusED's
Spawn new CED option never opened a new screen but a window because it
always got an errorcode of 0)
- OpenScreenTagList()/intuition now uses the width/height parameters of the
NewScreen structure instead of ignoring it and using the default dimensions.
- The mouse pointer should not jump around anymore if someone tries to drag a
non draggable screen (if driver has dragging disabled). Fix requires latest
drivers also
- fixed an enforcer hit problem that occured in conjunction with the SysLock
utility
Changes for 41.15 (r69d archive)
- hopefully fixes the crash problems introduced in r69c
- removed some debug output in the DoCDrawMethodTags()/cybergraphics call
which was in r69c/41.14
Changes for 41.14 (r69c archive)
- There is now a special ppc version of cgxsystem.library included. Please use
that if you have a ppc accelerator card.
- flood fill algorithm replaced by a faster version which leads to faster icon
redrawing in certain cases
Changes for 41.13 (r69b archive)
- If AllocBitMap()/graphics is called with the SPECIALFMT flag set, it now
uses the exact depth instead of using the supplied depth parameter.
Calling AllocBitMap() with the wrong depth for a certain pixel format
could lead to all kinds of problems with older versions.
- the 040 version of cgxsystem.library now correctly checks for the
availability of a 68040 CPU and fails to load if it can't be found
- LockBitmapTagList()/cybergraphics now works properly if a certain tag occurs
multiple times
- Fixed some weird clipping problems in 15/16/24 bit modes that were likely to
appear when there was memory installed in ZorroII address space (e.g. ZII
memory cards or A2000 turbo cards).
Changes for 41.12 (r69a archive)
- library recompiled with SAS/C 6.58 and global optimizer enabled
- fixed a BltBitmap()/graphics patch bug for Hi/True color bitmaps. The
expansion code for a single plane did not work properly which caused
problems with DiskSalv's startup window for example.
- fixed some screen open problems with programs like Digita's Organizer
- added 2 new LVOs to cgxsystem.library that handle communication with CGXMode
- modified the patch system to avoid trouble with MCP style hacks
- fixed a bug in the patterned line drawing code for hi/truecolor bitmaps
- another "SUPER" production has made it into CyberGraphX 3.
This time its SUPERGELS, a replacement for the original CyberGraphX GELs
system. It is disabled by default, you have to set
envarc:cybergraphx/SUPERGELS to "1" to enable it.
Make sure you have no tools like PatchControl running in front of the
monitor startup. To allow SuperGels to work, you need to run it after
the monitor startup.
- added a new kludge to fix the ViewByName problems in hi/true color modes.
- added new code to speedup standard wb pattern backfills. Probably interferes
with hacks like FastIPrefs. Please make sure to disable this kind of tools
if you experience any problems.
- fixed a bug in BltMaskBitMapRastPort()/graphics patch. If you used a
interleaved planar bitmap as source the mask modulo was not calculated
the way the original graphics.library function did it.
ADDITIONAL NOTE: Please make sure you put hacks like MCP AFTER the
CyberGraphX system is started into the startup-sequence. Otherwise MCP might
cause trouble. Don't install ObtainGIRPort related patches because they can
lead to semaphore deadlocks under certain conditions
cgxvideo.library
================
Changes for 41.10 (r69 archive)
- removed all CVision3D hardware dependencies. Instead it uses a generic CGX3
driver VStream API now. Make sure you have the latest drivers installed when
you use this library.
- added support for GIMMEZEROZERO windows
Changes for 41.8 (r67 archive)
- minor internal changes
Changes for 41.7 (r64 archive)
- added new source types SRCFMT_RGB15 and SRCFMT_RGB16 to allow for rgb
color space overlays
Changes for 41.6 (r63 archive)
- added new tag VOA_UseBackFill to allow for automatic backfill of simple
refresh layers when the color keying option is used.
Changes for 41.5 (r58 archive)
- cgxvideo.library does not allow to create overlay on interlace screens
anymore
- Fixed problem with wrong mousepointer colours when overlay was enabled.
This fix requires at least CVision3D driver V2.2
- fixed a bug with 15/16/24 bit opaque overlays
- added color keying support.
- New tag VOA_UseColorKey for CreateVLayerHandleTags() call added
- New tags VOA_ColorKeyPen and VOA_ColorKey for GetVLayerAttr() call
added
cgxbootpic.library
================
Changes for 41.7 (r69 archive)
- fixed a mismatched free mem size in image decoder
Changes for 41.6 (r58 archive)
- library now correctly supports library expunge which safes some memory
after system boot.
Changes for 41.5 (r56 archive)
- initial public release
CV64 driver
===========
Changes for 2.9 (r69f archive)
- modified MOVE16 bitmap swap in/out code to workaround a bug in certain
040 accelerator cards.
- fixed a potential race condition when an interrupt occured, the int handler
was already installed but the hardware was not initialized completely.
- (YES|NO) is also accepted for the BOOTLOGO tooltype now instead of (1|0)
- reenabled roxxler support. There is now an additional tooltype
USEROXXLER=(YES|NO) to disable roxxler manually. Default is enabled.
Changes for 2.8 (r69e archive)
- added os3 style doublebuffer support. Only works with dragging disabled
(tooltype DRAGGING=NO), otherwise any attempt to allocate a dbufinfo will
fail. Requires at least cgxsystem.library 41.16
Changes for 2.7 (r69c archive)
- the driver does not crash with divide by zero anymore at startup if modes
with pixelfrequencies less than 12.5 mhz or higher than 135mhz are loaded
Changes for 2.6 (r69 archive)
- added bitblit acceleration for some occasionally used minterms
- added 2 new driver calls
- fixed a problem in the bitmap swap code for interleaved bitmaps <= 16 cols
- the memory management code now uses a first in/first out mechanism for
bitmaps
- fixed a bug in the memory management code that only occured while mungwall
was running
- driver recompiled with SAS/C 6.58 and global optimizer enabled
- modified init code to workaround a bug of certain boards (int level is set
to 6 although it is programmed to 2 which could lead to lockups at startup).
- fixed a bug in patterned masked fill acceleration code for rgb screens
that was introduced in 2.5 (fixes a problem with colorwheel on rgb screens)
CV3D driver
===========
Changes for 2.15 (r69
