Jan 13, 2012
7 years 8 months Fixed a legend labelling issue (the zero was some times appearing as a very small number) and a legend under/over range issue for heat (that was not checking that the data was in [0,1])
Commit 763, by Mathias Bavay
Jan 12, 2012
7 years 8 months Fixed the PNG world file (so that we return the coordinates of the center of the cell) and updated the examples so that they perform correctly with the latest version
Commit 762, by Mathias Bavay
7 years 8 months Speed improvement for IDW based on the profiling performed by HES-SO's V. Grivel: the stations' positions are saved in two vectors (eastings and northings) before walking the grid. For low number of stations, this makes no visible difference. For lar
Commit 761, by Mathias Bavay
7 years 8 months After playing with pngcrush, a new filter has been enabled for the PNG compression. A specific compression strategy for deflate is also now enabled for indexed images. This keeps run time identical but offers a significantly smaller file size (compar
Commit 760, by Mathias Bavay
Jan 11, 2012
7 years 8 months Indexed gradients are now handled by the Gradient class and used by the PNGIO plugin to generate indexed PNGs (some consts in the code can toggle it back to non-indexed images). This leads to a significant speedup and large file size reduction. On a
Commit 759, by Mathias Bavay
7 years 8 months clearer error message when the file's header does not match its content
Commit 758, by Mathias Bavay
Jan 10, 2012
7 years 8 months The "freeze" color gradient now has a fixed point at zero celsius. A pointer error (related to the FILE pointer) has been fixed in PNGIO by making this pointer a class member. A much improved error message is now generated when a file can not be open
Commit 757, by Mathias Bavay
Jan 9, 2012
7 years 8 months Introducing smart legends: this tries to find a meanigful range and steps within that range. The choice of rounding the lower and upper bounds (thus not guaranteeing that the whole data fits in the legend) has been made as it could lead to more suita
Commit 756, by Mathias Bavay
7 years 8 months Changing the case of A3D_VIEW in ARCIO, fixed an image corruption issue in PNGIO (libpng just *forgets* to flush the file buffer...). Added a missing include in MeteoIO.h
Commit 755, by Mathias Bavay
7 years 8 months A new key has been added that was missing: GRID2DPATH that can be in intput and output. This key is now properly handled by the appropriate plugins. A new color reduction strategy has been implemented in the gradients and the PNG plugin: instead of r
Commit 754, by Mathias Bavay
Jan 7, 2012
7 years 8 months A few hard coded parameters have been declared as static const (color depth per channel, max color per channel) in order to make the code cleaner. A new method has been introduced in the Gradient class: setNrOfColors. This allows to specify a reduced
Commit 753, by Mathias Bavay
Jan 6, 2012
7 years 8 months The gradients now don't provide a transparency value (since it had to be either fully opaque or fully transparent) but only a boolean. PNGIO now uses a transparent color to encode transparency instead of a true alpha channel, leading to improved run
Commit 752, by Mathias Bavay
7 years 8 months A new gradient type has been added (blue-green isomorphic) and some small things improved thanks to valgrind (one potential out of bounds read and with callgrind some small speed improvements)
Commit 751, by Mathias Bavay
7 years 8 months New methods "moveByXY" and "moveByBearing" have been added to Coords, addressing issue 39. Code cleanup and extensive documenting have been performed on Graphics and PNGIO, that now supports creating world file (optionnally). A new option has also be
Commit 750, by Mathias Bavay
Jan 4, 2012
7 years 8 months Better handling of "autoscale": the min and max are almost always taken into account (this is usefull to set fixed points, like the snow line, the sea level, etc) and the autoscale bool is used to tweak a given gradient for better display in autoscal
Commit 749, by Mathias Bavay
7 years 8 months Now, the plots are fitted/optimized depending on the meteo parameter (if available). The proper metadata is written into the file (again, if available). More gradients have been implemented.
Commit 748, by Mathias Bavay
7 years 8 months A few options have been added to PNGIO and autoscale is now supported by the gradients.
Commit 747, by Mathias Bavay
Jan 3, 2012
7 years 8 months Now the color gradient can be chosen (given as an argument in the Gradient constructor). This is not yet really used by PNGIO, but this will come!
Commit 746, by Mathias Bavay
7 years 8 months The legend class is now free of hard-coded values in the middle of the code (all depends on the static consts).
Commit 745, by Mathias Bavay
Jan 2, 2012
7 years 8 months The NearestNeighbour 2D resampling algorithm has been reshaped in order to offer the same interface as BiLinear. A typo in its name has been fixed. But NearestNeighbour does not work properly (bug not found yet) A better way of submitting metadata t
