Fellows <fellowsd@cs.man.ac.uk> + + * tests/imgPhoto.test: Added tests of -compositingrule + + * doc/photo.n: Added documentation for "-compositingrule". + * generic/tkImgPhoto.c (ImgPhotoCmd,ParseSubcommandOptions): New + "-compositingrule" option for [$photo copy] subcommand, using + OPT_COMPOSITE flag and compositingRule field in SubcommandOptions + structure. + + * doc/FindPhoto.3: Documented the extra argument for the + compositing rule and the action to take if anyone wants to + maintain total backward-compatability. + + * generic/tk.h (TK_PHOTO_COMPOSITE_*): Defined values for use as + compositing rules. + (USE_OLD_PHOTO_PUT_BLOCK): Added a way for users to select the old + interface to Tk_PhotoPutBlock to provide an easier upgrade path. + + * generic/tk.decls: Alter Tk_PhotoPut*Block to Tk_PhotoPut*Block_Old + and introduce new slots for the old name of function with an extra + argument at the end for the compositing rule. + + * generic/tkImgPhoto.c (ImgPhotoCmd): Updated "transparency set" + subcommand to use TkSubtractRegion(). + + * win/tkWinRegion.c (TkSubtractRegion): + * mac/tkMacRegion.c (TkSubtractRegion): + * generic/tkInt.decls (TkSubtractRegion): + * unix/tkUnixPort.h (TkSubtractRegion): Added function to perform + the set-difference operation on regions; it seems all platforms + can support it, and it makes removing rectangular bits from + regions much easier. + + * generic/tkImgPPM.c (FileReadPPM): Reading a PPM/PGM always uses + the SET compositing rule because it is faster and the format does + not have any transparency information. + + * generic/tkImgGIF.c (FileReadGIF): Reading a GIF always uses the + SET compositing rule because GIF files model transparency as a + single special colour. + + * generic/tkImgPhoto.c (Tk_PhotoPutBlock, Tk_PhotoPutZoomedBlock): + Added a compositing rule to allow better control over what happens + to transparent pixels when inserting data into a photo image. + 2002-06-13 Mo DeJong <mdejong@users.sourceforge.net> * tests/winfo.test: Add basic tests for winfo ismapped. |
