Raw Blame History

2002-07-19 Jean-Marc Lasgouttes <lasgouttes@freesurf.fr>
* PreviewLoader.C (startLoading): use LibScriptSearch to find the
preview converter script
2002-07-18 Jean-Marc Lasgouttes <lasgouttes@freesurf.fr>
* GraphicsCacheItem.C (reset): use erase() instead of clear() for
strings
2002-07-18 Angus Leeming <leeming@lyx.org>
* GraphicsCacheItem.[Ch]: add a FileMonitor variable to the the Impl
class.
(startMonitoring, monitoring, checksum): new methods to interact with
the FileMonitor.
* GraphicsLoader.[Ch] (startMonitoring, monitoring, checksum): new
methods invoking the CacheItem methods of the same name.

new file.
2002-07-17 Jean-Marc Lasgouttes <lasgouttes@freesurf.fr>
* Makefile.am: remove FileMonitor.[Ch]
2002-06-17 Herbert Voss <voss@lyx.org>
* GraphicsCachItem.C (findTargetFormat): remove the speciell case
for old ps-files (Garst). It's now handled by defining a converter and
disabling the ps-support of xforms.
2002-07-17 Angus Leeming <leeming@lyx.org>
Be true to the Pimpl idiom, moving all signals into the respective
Impl classes and defining methods to connect them to an outside slot.
Const-ify all visible class methods as they act only on a const pimpl_.
* GraphicsCache.[Ch] (add, remove): const-ify.
* GraphicsCacheItem.[Ch] (startLoading): const-ify.
(statusChanged): move the signal into the Impl class.
(connect): new method, enabling a listener to connect to this signal.

(finishedConversion): move the signal into the Impl class.
(connect): new method, enabling a listener to connect to this signal.
* GraphicsLoader.[Ch] (reset, startLoading): const-ify.
(statusChanged): move the signal into the Impl class.
(connect): new method, enabling a listener to connect to this signal.
* PreviewLoader.[Ch] (add, remove, startLoading): const-ify.
(imageReady): move the signal into the Impl class.
(connect): new method, enabling a listener to connect to this signal.
(emitSignal): new method, enabling PreviewImage to tell the outside
world that the file has been loaded into memory.
* Previews.[Ch] (loader, removeLoader, generateBufferPreviews):
const-ify.
* GraphicsCache.C:
* GraphicsCacheItem.C:
* GraphicsConverter.[Ch]:

* PreviewLoader.[Ch]: whitespace clean-up.
2002-07-16 Jean-Marc Lasgouttes <lasgouttes@freesurf.fr>
* PreviewLoader.C (setConverter): remove unused variable
* GraphicsImageXPM.C (isDrawable): implement
(setPixmap): the opaque color is black, not white
2002-07-15 Jean-Marc Lasgouttes <lasgouttes@freesurf.fr>
* GraphicsImageXPM.C (color_none_id):
(contains_color_none): use ascii_lowercase instead of lowercase
2002-07-16 Angus Leeming <leeming@lyx.org>
* PreviewLoader.C: greater use of STL algorithms.
* Previews.[Ch]: use const in more places.
(generateBufferPreviews): now takes a Buffer const & argument, not a
pointer.
2002-07-15 John Levon <moz@compsoc.man.ac.uk>
* GraphicsImage.h: remove getPixmap/X, add isDrawable()
2002-07-12 Angus Leeming <leeming@lyx.org>
* GraphicsLoader.[Ch]: smart loading of images. Images are loaded only
if visible 2 secs after the call to load them is first made.
* GraphicsSupport.[Ch]: new files. isInsetVisible interrogates the
BufferView to ascertain whether the inset is visible or not.
* Makefile.am: added GraphicsSupport.[Ch].
* PreviewImage.[Ch]: use this smart loader.
* PreviewLoader.C: don't load generated image files indiscimminantly.
Instead emit the imageReady signal and allow the image owner to decide.
2002-07-12 John Levon <moz@compsoc.man.ac.uk>
* GraphicsCache.C: remove init_graphics()
2002-07-09 Angus Leeming <leeming@lyx.org>
* PreviewLoader.C (setAscentFractions): fix bug due to use of integer
arithmetic when it should be floating.
2002-07-09 Angus Leeming <leeming@lyx.org>
* PreviewLoader.C (startLoading): prepend LaTeX file with "\batchmode".
Output equation labels as "(#)" if lyxrc preference is set.
(setFontScalingFactor): use lyxrc variable preview_scale_factor
rather than hard-coding this.
2002-07-09 Angus Leeming <leeming@lyx.org>
* PreviewLoader.C: Further refactoring of the code. Should now be
pretty clean.
* PreviewMetrics.[Ch]: removed. Had a v. short shelf life and is now
past its sell-by date. The code to read the metrics file is now found
as a helper function in PreviewLoader.C.
* GraphicsImageXPM.C (scale): use boost::tie.
2002-07-08 Herbert Voss <voss@lyx.org>
* PreviewLoader.C: use of preview_size_factor to get the right
font-size! 0.9 is the default.
2002-07-08 Angus Leeming <leeming@lyx.org>
* PreviewLoader.C: Add "delayed" and "showlabels" options to the
invocation of preview.sty.
Perform something of an internal clean-up.
2002-07-06 Angus Leeming <leeming@lyx.org>
* PreviewLoader.C: ensure that the metrics data is used by the
correct image!
* PreviewLoader.C:
* PreviewImage.C: (Impl d-tor): remove all generated files that still
exist (perhaps because the process was curtailed before the images
were loaded.)
* PreviewLoader.C (unique_filename): store the files in Buffer::tmppath.
2002-07-05 Angus Leeming <leeming@lyx.org>
* PreviewImage.h:
* PreviewImage.C:
* PreviewLoader.h:
* PreviewLoader.C:
* PreviewMetrics.h:
* PreviewMetrics.C:
* Previews.h:
* Previews.C: new files. The previewed LaTeX snippet stuff.
* Makefile.am: add these files.
2002-07-05 Angus Leeming <leeming@lyx.org>
* GraphicsLoader.h: whitespace.
2002-07-04 Lars Gullik Bj<42>nnes <larsbj@birdstep.com>
* GraphicsImage.[Ch]: newImage and loadableFormats changed to
boost::function from boost::signal.
2002-07-01 Jean-Marc Lasgouttes <lasgouttes@freesurf.fr>
* GraphicsConverter.C (convert): do not use ChangeExtension
because to_file_base may contain a dot.
2002-06-28 Angus Leeming <leeming@lyx.org>
* GraphicsCacheItem.[Ch]: refactor some of the more convoluted logic
by moving those SignalPtrs into the grfx::Image and grfx::Converter
classes where they really belong.
Use the Pimpl idiom to hide the class internals from public view.
* GraphicsTypes: remove the typedefs, leaving only the enums.
* GraphicsImage.h: now has a finishedLoading signal, as opposed to being
passed a reference to one in the load() method.
* GraphicsConverter.[Ch]: totally refactored. An instance of
grfx::Converter now represents a single conversion process.
Thus grfx::CachItem now has a grfx::Converter * that is set when the
conversion is initiated and destroyed on completion.
* GraphicsCache.[Ch]:
* GraphicsCacheItem.[Ch]:
* GraphicsConverter.[Ch]:
* GraphicsLoader.[Ch]: use the Pimpl idiom to hide the class internals
from public view.
Note that I have done this only after making the above changes,
so not only should we have a clean, minimal and well documented
interface to these classes in the header files, but the class internals
should be much clearer too.
* Renamed classes
grfx::GCache -> grfx::Cache,
grfx::GCacheItem -> grfx::CacheItem,
grfx::GConverter -> grfx::Converter,
grfx::GImage -> grfx::Image,
grfx::GImageXPM -> grfx::ImageXPM,
grfx::GParams -> grfx::Params.
2002-06-26 Angus Leeming <leeming@lyx.org>
* GraphicsLoader.[Ch]: use boost::scoped_ptr in preference to
std::auto_ptr. Define an empty Loader d-tor out-of-line to ensure it
compiles.
2002-06-26 Angus Leeming <leeming@lyx.org>
* GraphicsTypes.h: add "Ready" to the ImageStatus enum.
move the DisplayType enum out of grfx::GParams to here.
* GraphicsCacheItem.h: re-write preliminary description to reflect
current reality.
* GraphicsParams.[Ch]:
* GraphicsImageXPM.C (load, setPixmap): changes aassociated with moving
grfx::DisplayType out of grfx::GParams.
* GraphicsLoader.[Ch]: new files. Factor out the image loading stuff
that was in frontends/screen.C and insets/insetgraphics.C into a
single, easy-to-use class.
* Makefile.am: add these files.
2002-06-25 Angus Leeming <leeming@lyx.org>
* GraphicsCache.[Ch]:
* GraphicsCacheItem.[Ch]:
* GraphicsTypes.h: rewrite the graphics cache to just load a graphics
file into memory. The cache no longer controls the generation of the
pixmap. Instead, it just emits a signal when the loading status of an
image changes.
The cache no longer stores InsetGraphics pointers and nor does it
assume responsibility for modifying an image (scaling, rotating etc).
Instead, that must now be performed elsewhere.
2002-06-19 Angus Leeming <leeming@lyx.org>
* GraphicsConverter.C: add using std::endl directive.
2002-06-17 Herbert Voss <voss@lyx.org>
* GraphicsCachItem.C: (findTargetFormat)return xpm-format as a
default when nothing different was found
(convertToDisplayFormat): handle zipped files in the right way and
choose always convert as a default converter when no other
userdefined was found
* GraphicsConverter.C: add more lyxerr comments and choose
convert when no other userdefined converter was found
2002-06-10 Herbert Voss <voss@lyx.org>
* GraphicsImageXPM.C (convertTo7chars): get another special color
format from convert work in the right way
2002-06-12 John Levon <moz@compsoc.man.ac.uk>
* GraphicsCache.C: use right colormap incantation
2002-06-12 John Levon <moz@compsoc.man.ac.uk>
* GraphicsCache.C: use lyx_gui namespace
* GraphicsImageXPM.C: back down to using xforms
directly again
2002-06-07 Angus Leeming <leeming@lyx.org>
Fixes needed to compile with Compaq cxx 6.5.
* GraphicsConverter.h: forward declare class ConvProcess.
* GraphicsImageXPM.C:
all c-library variables have been moved into namespace std.
Wrap using std::xyz declarations inside a #ifndef CXX_GLOBAL_CSTD block.
2002-06-06 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsImageXPM.C (rotate): rotate in the same sense as xdvi!
2002-05-30 Lars Gullik Bj<42>nnes <larsbj@birdstep.com>
* GraphicsImageXPM.C: SigC to boot::signals changes.
(newImage): fix () bug when using new.
2002-05-29 Lars Gullik Bj<42>nnes <larsbj@birdstep.com>
* switch from SigC signals to boost::signals.
2002-05-29 Andr<64> P<>nitz <poenitz@gmx.net>

* GraphicsTypes.h: ditto
* GraphicsImage.h: ditto
* GraphicsConverter.h: ditto
2002-04-28 John Levon <moz@compsoc.man.ac.uk>
* GraphicsImageXPM.C: understand convert's use of "opaque"
as a colour name
2002-04-19 Marco Morandini <morandini@aero.polimi.it>
* GraphicsCache.[Ch] (loadableFormats): new method. A wrapper for
GImage::loadableFormats() that ensures that the signal is connected
to the derived class' method.
2002-04-18 Lars Gullik Bj<42>nnes <larsbj@birdstep.com>
* GraphicsImageXPM.C (convertTo7chars): drop all conversions and
only work on the string.

the simple image loader when it encounters colour strings like
#rrrrggggbbbb.
2002-04-16 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsCacheItem.C (convertToDisplayFormat):
* GraphicsConverter.C (build_script): remove the Alerts when things go
wrong as the inset displays the message anyway. Moreover, Alert seems
pretty temperamemtal at the moment.
2002-04-16 Rob Lahaye <lahaye@users.sourceforge.net>
* GraphicsImageXPM.C: fix clipping for boundingbox y-coordinates
2002-04-08 Angus Leeming <a.leeming@ic.ac.uk>

a reference to a temp object that's going out of scope...
2002-04-09 Herbert Voss <voss@lyx.org>
* GraphicsParams.C (BoundingBox c-tor): fix rounding errors by using
LyXLength::inBP instead of inPixels.
2002-04-10 Herbert Voss <voss@perce.de>
* GraphicsCache.[Ch]:
* GraphicsCacheItem.[Ch]: add width/height functions from Angus
to read the "Bounding Box" from non (e)ps files.
2002-04-08 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsParams.C (c-tor): if clipping, then check the Bounding Box of
the EPS file too, to ensure that the clipped Bounding Box is relative
to the original. (From Herbert.)
2002-04-04 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsParams.C (BoundingBox c-tor): ensure that the member

* GraphicsCacheItem.C: ws change
2002-03-05 Angus Leeming <a.leeming@ic.ac.uk>
* Makefile.am: if there is no image loading class leveraging the power
of the appropriate gui library, then compile the basic alternative
found in GraphicsImageXPM.[Ch].

* GraphicsCache.C: change associated with move of initialiseGraphics
to GUIRuntime.
2002-02-28 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsParams.[Ch]:
* GraphicsImage.C:
* GraphicsImageXPM.C: properly resolve more warnings about comparison
between signed and unsigned integer expressions.
* Makefile.am: add GraphicsTypes.h which I'd carelessly left out.
* GraphicsCache.C: move connections to the GImage-derived classes to
the frontends.
* GraphicsImageXPM.C (copy c-tor): don't copy pixmap.
* GraphicsCacheItem.C (findTargetFormat): if we can load direct without
conversion, then do that.
2002-02-27 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsCache.C: improve commentary to graphicsInit and where it
should really go.
* GraphicsImageXPM.C (~Data, free_color_table): resolve the crash
that became a memory leak properly. (Let the shared_c_ptr free the
color table.)

with crappy color entries. Print out a nice friendly message on what's
gone wrong and how to resolve it properly.
2002-02-27 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsImageXPM.[Ch]: more rigorous use of types (signed/unsigned).
(Data d-tor): introduce memory leak temporarily, to "fix" a crash
in free_color_table.
(unique_color_string): use the correct string c-tor.
2002-02-15 Angus Leeming <a.leeming@ic.ac.uk>
* ImageLoader.[Ch]:
* ImageLoaderXPM.[Ch]: removed.
* GraphicsConverter.[Ch]:
* GraphicsImage.[Ch]:
* GraphicsImageXPM.[Ch]:
* GraphicsParams.[Ch]:
* GraphicsTypes.h: new files.

The old LyXImage and ImageLoader have been combined in a new class
GImage. Ditto, ImageLoaderXPM's functionality has been moved into
GImageXPM.
2002-02-07 Herbert Voss <voss@lyx.org>
* GraphicsCacheItem.C: use unzipFile() from support/filetools
2002-01-31 Herbert Voss <voss@lyx.org>

2001-09-21 Angus Leeming <a.leeming@ic.ac.uk>
* ImageLoaderXPM.C (runImageLoader): If the pixmap contains a
transparent colour, then set it to the colour of the background.
Also take account of the monochrome, grayscale of color
preferences option.
2001-09-20 Angus Leeming <a.leeming@ic.ac.uk>
* GraphicsCacheItem.C (convertImage): only convert if "from" and "to"
are different. Thus, don't delete the "to" if it's the original!
2001-09-01 John Levon <moz@compsoc.man.ac.uk>

* ImageLoader.h: ditto
* GraphicsCacheItem.h: ditto
2001-04-16 Allan Rae <rae@lyx.org>
* ImageLoaderXPM.C (runImageLoader): #warning triggers an error on Sun
CC 6.0 as an unrecognised preprocessor directive. So ensure they're
wrapped.
2001-04-02 Baruch Even <baruch@lyx.org>
* GraphicsCacheItem.[Ch]: Changed to used the Converter class instead
of hard coding ImageMagick.
2001-03-10 Baruch Even <baruch@lyx.org>
* GraphicsCache.C: Style change from (*it).field to it->field
2001-03-15 Lars Gullik Bj<42>nnes <larsbj@trylle.birdstep.com>
* GraphicsCache.h: noncopyable is in namespace boost
* ImageLoader.h: ditto
* GraphicsCacheItem.h: ditto
2001-03-07 Baruch Even <baruch@lyx.org>
* GraphicsCache.C (d-tor): Removed the assert, the assumption it carried
was false and it's not needed anyhow since the shared_ptr's in the cache
will destroy everything on exit.
2001-02-28 Baruch Even <baruch@ev-en.org>
* GraphicsCache.h:
* GraphicsCache.C: Changed the singleton pattern implementation, the
former version "leaked" in the sense that it was not deallocated at
program end.
2001-02-20 Baruch Even <baruch@ev-en.org>
* GraphicsCache.C: Changed to use shared_ptr<GraphicsCacheItem>
instead of a pure pointer.
* GraphicsCacheItem.[Ch]:
* GraphicsCacheItem_pimpl.[Ch]: Collapsed them into GraphicsCacheItem,
removed the reference counting that was inside. Also fixed a bug where
a temporary file wouldn't get erased.
* ImageLoader.[Ch]: Changed the semantics of the image_ pointers usage.
Ownership is now dropped when the caller requests the image_ pointer.
2001-02-20 Baruch Even <baruch@ev-en.org>
* GraphicsCache.C: Cleared up the confusion on when and how it is
emptied.
* GraphicsCacheItem.C: Indentation change.
* GraphicsCacheItem_pimpl.C: Fixed the loading logic so that it will
figure correctly when the image has been loaded successfully.
2001-02-08 Jean-Marc Lasgouttes <Jean-Marc.Lasgouttes@inria.fr>
* ImageLoader.C: add a "using" directive.
* ImageLoader.h: remove extra comma at the end of enum; add an
std:: qualifier for vector.
2001-01-21 Baruch Even <baruch@ev-en.org>
* GraphicsCacheItem.[Ch]: Changes due to the storage of width and
height in the image itself and minor cleanups.
* GraphicsCacheItem_impl.[Ch]: Changes due to the switch to use a
new ImageLoader class instead of the older Renderer class. This
means change of responsibilities.
