This curve is actually created using a bicubic Bezier curve, but that's not important I believe. At the moment there should be no "holes" within the drawn shape. So it will just be totally filled in. It seems

问题 In the BGI library's "graphics.h" header there is a function pieslice in that header file,its syntax is: #include <graphics.h> void pieslice(int x, int y, int stangle, int endangle, int radius); [x,y are the center of the circle,stangle and endangle are the starting and end angles respectively] Can we make a pieslice in C/C++ without using this in-built function of the BGI library.Please help. Tried making it with the help of the lines and mid-point circle generation algorithms. My code so

问题 for my iOS Swift project I use vectorized pdf files from which Xcode renders the @1x, @2x, @3x images. When I compare the quality of the images generated from PDF with normal PNG images of the same size I see a big difference in the quality between them. Theoretically the quality of the first row and the third row in the following picture should be the same, because a 108x80 image should be rendered and used from my 54x40 PDF on my iPhone 6 with a normal retina display. Unfortunately the

问题 I have myfile.ps with a vector image included. But when I run ps2pdf myfile.ps it seems that the output page size is A4: the vector image is too large and become cut away, so about one inch is lost. The following pseudo-header is printed in the output PDF file, in addition to the original vector image: PLOT SIZE:8.02x8.62Inches Magnification:7354.21X Is there any option or any way to convert the PS file to a PDF preserving the original paper size? 回答1: I doubt your quoted 2 lines are really
