VenomGFX 8.1 (Announce)

Today I uploaded into my site the new version of my graphics library VenomGFX for Freepascal.
You can donload it here: http://www.laaca.borec.cz/soubory/venom.rar

Changes in new version:
+ can load images inside .GRP archives. (Note that this ability has
the addon FN_Font2 too)

- fixed bugs with banked modes for cards with separated read and
write access windows like ATI Mach64.

+ all graphics primitives can be drown directly on screen even in
banked modes!

+ graphics primitive PieSlice3D
- new and better GIF loader. The former one didn't work reliably.
* new compact JPG loader (however alternatively you still can use
the previous one based on PasJPEG library.
more info in NOTE 1 below)
* optimalizations in many procedures and functions

+ High level procedures can use alternate PutPixel and Line variants.
In this way you can draw f.e. semitransparent ellipses or XORed
boxes, etc.

+ improved documentation

New version - download, as usual, at http://www.laaca.borec.cz/soubory/venom.rar

There is only change:
in windows NT, 2000, XP,... ...are disabled the LFB video modes.
I am disgusted but it is the reality - these windows versions claim that they can do LFB but don't.

Why is this RAR file ~45 Kbytes larger than the previous version?

I probably forgot to use the "-m5" switch when packing. :-P

It is a graphics library for DOS version of Freepascal.
It contains extremaly many graphics primitives, some of them very unique like rotated elliptic chords or rounded boxes. Most graphics primitives can also use thick and masked lines.
Except that very many sprite functions are implemented, you have many types of image loaders include .WMF vector format.
More info inside VENOMGFX.TXT file and in comments in sources.

Changes:

8.22
+ FastThickLine, ThickLine, LineThickWithMask
+ these graphics primitives: [Rectangle, Polygon, FilledPolygon,
RotatedNShape and RotatedFilledNShape] have now optional parameters
for selecting thickness and mask of used lines
+ these grapics primitives: [Circle, FilledCircle, Ellipse,
FilledEllipse, RotatedChord, RotatedFilledChord, RotatedEllipse and
RotatedFilledElipse] have now optional parameter Thickness
* removed procedures Ring and Ring2 because they are now obsolete
* image loaders are moved into separated units
+ loader for .WMF format
+ even the PasJPEG based JPEG loader can now load images inside
.GRP archives
- fixed bug in PNG and GIF loaders resulting to wrong colors
(this bug was introduced in version 8.2)

Hi,
Since I know this is used by your popular editor Blocek, which is included in FreeDOS and mirrored on iBiblio, I checked to see what was there. I wasn't even sure what was there, and I'm not even sure they archived the entire thing properly. Anyways, it was the old version before you upgraded the compiler, so I decided to just re-upload everything (and move previous stuff to "old/").

In other words, feel free to double-check and tell me if it's right, wrong, or what to add, delete, rename, etc!
