Re: [Plplot-devel] Fwd: [plplot - plplot-devel] Plplot print problem on Wingcc driver
Hi, The Wingcc printing function uses a Win3.11 API entry point which is simpler (in all respects) than other APIs windows has for printing. One side-effect is it leaves the burden of responsibility for certain things upon the user to ensure all is correct with the printer; consequently you need to change the default aspect ratio of the printer (through the control panel preferences) to the one closest matching that of the plot window, which usually means changing it from portrait (the usual default) to landscape. When that is done I think the printing will do the whole page. -Andrew At 02:48 PM 20/02/2009 +0100, you wrote: Hi list, maybe some of you have an idea.

Re: [Plplot-devel] plfreetype smooth=1 bug for example 24
I've pinned down the problem, but I'm not quite sure why the code is written the way it is. The problem arises in src/plfreetype.c in FT_PlotChar. There are two different code paths depending on whether the pixel mode is mono (i.e. no anti-aliasing) or not. However, the first path is also taken if icol0 = 0, i.e. the background colour. I can't quite see the logic for this. Normally is is not a problem since you wouldn't display text in the background colour. Example 24 however plots 4 coloured bands so you can't see the background, then switches to the background colour to print the text. The crazy fonts arise because the code assumes a mono font - i.e. each pixel is represented by one bit. This is not the case for the anti-aliased text in the background colour. I've just commented out this special case for icol0 = 0. I don't quite see why it was there in the first place. This fixes example 24. Perhaps someone better familiar with the freetype code could say why this was done originally? My recollection, late at night and a few years down the track, is that with the original anti-aliasing technique (i.e. not the BLENDED ANTIALIASING which 24bit supports, but the ugly anti-aliasing which also works with 8bit), when the text colour had an index of 0, there were either infrequent division by zero errors or some distracting psychedelic anti-aliasing effects/artifacts. I can not remember which for sure, but regardless dropping background coloured text back to non-antialiasing was the quick way to fix the problem which had minimal impact since drawing text with the background colour was virtually never done. In short, it was a quick design compromise to fit the original simplistic code used for anti-alaising when working with limited colours like 8 bit palettes used by GIFs or the lower-resolution drivers of the day. -Andrew -- This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ___ Plplot-devel mailing list Plplot-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/plplot-devel
Re: [Plplot-devel] Plotting time axes

Note, however, hardware is rapidly moving to 64-bit right now. For example, my impression from a recent computer buy is that 64-bit has become the norm rather than the exception for new PC's. Thus, on PC's at least, I don't think the above 32-bit time_t issue is going to be relevant for too much longer. Just to put things in context, even 32-bit versions of Windows now treats time internally as an unsinged 64-bit int measured in 100 nanosecond intervals from 1st January 1601. -Andrew - This SF.net email is sponsored by: Microsoft Defy all challenges.

Re: [Plplot-devel] proposed freetype changes
Hello Werner, At 09:42 AM 24/01/2007 +0100, you wrote: Hi, I have a proposed change for the freetype part of plplot: for the wxwidgets driver I'm using not only one scaling factors but two (for x and y), which is nicer if you resize the windows. But since the freetype interface allows to set only one scaling factor, the font output is a mess if I resize the window for the wxwidgets driver if freetype is enabled. I have now replaced the scaling factor scale, by scalex and scaley, made corresponding changes in the code of plfreetype.c and gd.c and wingcc.c (which set both factors to the same value, so here is no impact). Does anyone have objections if I commit that changes? May I make a suggestion ? Keep scale, add scalex and scaley, and add logic so that if scalex and scaley are defined, they are used to scale the plot, but if they aren't then scale is used ? That way the changes will be 100% backwards compatible. -Andrew - Take Surveys. Earn Cash.

Re: [Plplot-devel] pdf driver
At 10:53 PM 29/12/2006 +0100, you wrote: Hi, while working on a plot for my thesis I thought it would be cool to have pdf output. I was googling around and found a free pdf library (zlib license) in ANSI C, working on all major platforms: http://libharu.sourceforge.net/index.html Nice ! About five years ago I wrote a PDF driver using a PDF library whose source code was available, but wasn't Open Source - rather some unusual licence - so shelved it. I looked at libharu as an alternative when they first released it, but at the time it was dependent on C++, so I didn't pursue it at all. Having looked at their web page just now, it seems that version 2 is ANSI C - is that right ? Or does it still have dependencies with C++ ? 2) The paper size is hardcoded to A4 in the moment - good for Europeans, bad for anybody else, I need to add some flags for other formats. A4 is probably best for everyone EXCEPT North Americans, so don't feel bad about that ! Might I also suggest letting the user set their own explicit page dimensions using plplot's regular command line options as well as flags for pre-defined sizes ? -Andrew - Take Surveys. Earn Cash.
