In the process of using UG software drawing, sometimes the drawing files can not be saved; When encountered this situation, if not handled well, it is necessary to from the preservation of that step back to design, in this experience, to explain to everyone I encountered in the UG drawing files can not be saved when the solution. 1, in the use of UG9.0

In the previous piece has been introduced to you how to use GDI + to draw a simple image, this piece continues to introduce some other drawing knowledge. 1. First, let's look at the pen we used in the last piece. Pen properties are mainly: color (color), dashcap (dash End shape), dashstyle (dotted style), endcap (line End shape), startcap (thread shape), Width (thickness), and so on. We can use pen to draw dashes, lines with arrows, etc. Pen　p = n

Before the tutorial we gave examples of the proposition: known: trapezoid ABCD, Ad∥bc,ab=ad+bc,e is the midpoint of the CD. Verification: AE, be divided equally ∠bad, ∠abc. The converse proposition of the proposition is: in the trapezoid abcd, the Ad∥bc,∠dab and the ∠CBA of the intersection point E, and point e happens to be on the waist CD. Then: Ab=ad+bc,e is the midpoint of the CD. Obviously, we can learn about ∠aeb=90°. As shown in the following figure, the midpoint of the segment AB is th

My study notes are mainly recorded in the study opencv-python-tutorials the book of the NotesThis evening learn how OpenCV for Python plots, mainly using these functions (these functions can be in: http://docs.opencv.org/modules/core/doc/drawing_functions.html Found):Start by copying the code from the book, the code is as follows:Import NumPy as NP Import = Np.zeros (512,512,3= Cv2.line (IMG, (), (510,510), (255,0,0), 5= Cv2.rectangle (IMG, ( 200,100), (100,200), (0,255,0), 3= Cv2.circle (img,

To give you illustrator software users to detailed analysis to share the drawing of linear fringe geometric art patterns of the tutorial. Tutorial Sharing: First, create art brushes To make a stripe pattern, the first thing we need to think about is what tools are used to achieve it more quickly. Because such as stripes, dots, squares ... This kind of basic pattern has the common character that repeats a certain visual law

To the users of the painter software to the detailed analysis of the painting to share the effect of the tutorial. Tutorial Sharing: 1. Create a new 800x600 pixel file. 2. Add a new normal layer, set composite method for gel. 3. Double-click the new layer, and in the Out Layer property panel, name the layer "XM" (line Drawing). Use the pencils/2b pencil brush, and then select a light gray in the colors panel, sele

June has been busy in the final exam, today to quickly learn the Ggplot2 package of simple drawing.There are also many drawing functions in the base package of R, such as plot (); Barplot (); Qqplot ();But there is also the famous Ggplot2 bag, using the function of this package to draw a beautiful picture, and the use of flexible. In Ggplot's Official Handbook, a statistical graph is made up of data to geometric objects (geometric object, recorded as

The MATLAB Help document is as follows: Hold on holds the current plot and all axis properties, including the current color and linestyle, so that subsequent grap Hing commands Add to the existing graph without resetting the color and LineStyle. Hold OFF returns to the default mode whereby PLOT commands erase the previous plots and reset all axis properties before D Rawing new plots. corresponding translationhold on: maintains the current drawing an

The iOS view mechanism, referring to the iOS view box can be drawn by DrawRect itself, each view of the layer (Calayer) is like a view of the projection, in fact, we can also manipulate it to customize a view, such as a translucent rounded background view.To complete your drawing on the view, be sure to look at the drawing mechanism of iOS. Today I'm trying to talk about iOS

To pull a map is to isolate a particular object from the background, and the premise of the pull is that we have a completely clear image. In the process of image processing, the drawing is very popular, especially for web design, poster design and cover design. The prospect of drawing extraction may be a combination of people, objects or landscapes, or three factors. This issue of foreign quality transla
