- From Onuchin:
In batch, when a picture was saved in a binary file (gif for instance) from
an image containing more than one pad, only the first pad was saved. The
following macro demonstrates the problem: ccc2.gif was wrong compared to
ccc1.gif.
{
gROOT->SetBatch();
TCanvas *c = new TCanvas;
c->Divide(1,2);
TH1F *h = new TH1F("gaus", "gaus", 100, -5, 5);
h->FillRandom("gaus", 10000);
c->cd(1); h->Draw();
c->cd(2); h->Draw("c*");
c->Print("ccc1.gif");
TImage *img = TImage::Create();
img->FromPad(c);
img->WriteImage("ccc2.gif");
}

From Valeriy:
TGPicture:
- fix deallocation autogenerated disabled pictures. That allows to fix
seg. violation after running $ROOTSYS/test/stress reported by Markus Frank.
An important comment was added to constructor
TGPicture(const char *name, Pixmap_t pxmap, Pixmap_t mask)
"both pixmaps pxmap and mask must be unique (not shared)"
- new method TGPicturePool::GetPicture(const char *name, char **xpm) added
that allows to create pictures from in-memory XPM array
Example:
#include "myicon.xpm" // contains static char** myicon {..} array
const TGPicture *pic = gClient->GetPicturePool()->GetPicture("myicon",
myicon);
TGButton:
- new method SetEnablled added which allows to activate/deactivate
enabled/disabled state of button
TASImage/TImage:
- Few new vector graphics methods added:
DrawCubeBezier, DrawStraightEllips, DrawCircle, DrawEllips,DrawEllips2
ToGray method, which allows to convert RGB image to Gray image
TImageDump:
- open circle polymarkers are implemented

From Valeriy Onuchin:
- TASImage class:
o new method GetImageBuffer is introduced. It returns in-memory buffer
compressed according to the image type.
Buffer must be deallocated after usage.
This method can be used for sending images over the network.
o new method SetImageBuffer introduced. It creates image from compressed
buffer. Supported formats:
PNG - by default
XPM - two options exist:
1. xpm as a single string (raw buffer). Such a string
is returned by GetImageBuffer method.
For example:
char *buf;
int sz;
im1->GetImageBuffer(&buf, &int, TImage::kXpm); /*raw buffer*/
TImage *im2 = TImage::Create();
im2->SetImageBuffer(&buf, TImage::kXpm);
2. xpm as an array of strigs (preparsed)
For example:
char *xpm[] = {
"64 28 58 1",
" c #0A030C",
". c #1C171B"
...
TImage *im = TImage::Create();
im->SetImageBuffer(xpm, TImage::kXpm);
o custom Streamer was implemented. That allows to save images in ROOT files.
Image's thumbnail is also saved into a file.
o galaxy_image.C tutorial is modified according to new saving schema.
o new demo file gallery.root added to tutorials. It contains thumbnailed
and browsable pictures produced by some ROOT tutorials.
o fix bug im TASImage::DrawRectangle methods. Thanks to Thomas Bretz
for reporting it.
- TKey class.
Possibility to save thumbnail/icon as XPM string along with object added.
Currently such mechanism is used for saving thumbnailed images.
- TGPicture. Platform-dependent code was removed. Now TGPictures
are created by TImage objects.
- TRootBrowser classes. Possibility to show objects with dynamically created
icons added.
- numerous bug fixes in libAfterImage library.

From Valeriy Onuchin:
1. TVirtualPS - 3 "abstract" methods added
void *GetStream() const
returns pointer to "backend", which is file stream for
TPostScript, TPDF, TSVG classes, and is TImage object for TImageDump
class.
void SetType(Int_t) , GetType() const
setter/getter methods
2. TImageDump
If type is 114 - do not write to file on delete or Close()
3. TASImage
- more 10-20% gain achived in drawing speed
- fix problems in painting image in batch mode, e.g.
$root -b
root[] .x rose_image.C
root[] c1->Print("c1.png")

From Valeriy Onuchin:
- new class TImageDump derived from TVirtualPS is introduced.
That allows to save canvas in GIF, JPEG etc, image formats in batch mode.
This patch is introduced to check the portability of the code on all
platforms. More additions coming soon to:
- text rotation
- correct text alignment (y-centered)
- 1pixel frame drawing
- fix saving in PNG format
- speed optimisation
