lapdf – PDF draw­ing di­rectly in TeX doc­u­ments

The pack­age pro­vides the means to use PDF draw­ing prim­i­tives to pro­duce high qual­ity, col­ored graph­ics. It – uses Bézier curves (in­te­gral and ra­tio­nal) from de­gree one to seven, – al­lows TeX type­set­ting in the graphic, – of­fers most of the stan­dard math func­tions, – al­lows plot­ting nor­mal, para­met­ric and po­lar func­tions.
The pack­age has lin­ear, logx, logy, logxy and po­lar grids with many specs; – it can ro­tate, clip and do many nice things eas­ily – it has two loop­ing com­mands for pro­gram­ming and many in­struc­tive ex­am­ple files.
The pack­age re­quires pdfTeX but oth­er­wise only de­pends on the calc pack­age.
