draw

问题 I have been trying to find out if it is possible to draw only a section of a shape using EaselJS. For example, is it possible to create a Rounded Rectangle, but only draw the top two thirds of it? (Effectively not displaying the bottom third). Thank you in advance for any advice you may have! 回答1: What is the end goal? Depending on what you want to do, there are a few ways to do it: Mask it using another shape to crop it Cache it to the size you want http://jsfiddle.net/lannymcnie/f1zh3qwx/ /

问题 I'm trying to make a function in Lua or VB based code to draw / plot a filled ellipse. I don't have much knowledge about this math and I can use some help. I Googled everything there is to Google about drawing ellipses with code but I can't find a good simple working example in VB or Lua for a filled one. On a previous post on this site I did get an answer about how to draw a normal ellipse but nothing came up for a filled one, that's why i make a new topic for a filled one. Here are a few

问题 I have a similar question to this one here: Drawing a line by mouse in a panel And i've actually used the first solution in the list, with great success, by creating a UserControl called SuperPanel . However, I want the model for this to be driven by something other than MouseDown and MouseUp on the SuperPanel. I want it to be set to either ON or OFF by calling a public method, which will be called by the event handler of another control like a button... Is that possible? Every which way i've

问题 For my assignment I am supposed to make a Draw a diamond with asterisks using methods. I figured out how to make the first part (centered triangle) I cannot for the love of God figure it out. I have spent over 4 hours trying different things and I figured how to make an upside down triangle, but the diamond is not working out. This is what I have for the first part. Can someone tell me how to flip it so that it will form a diamond when used with an upside down version? { int rows =

问题 Ok! Here goes. I've updated my code. However, after hours of debugging seemingly perfect code, I can't spot the problem. I've set up multiple breakpoints around the Vertex and Index buffer creation, and the class draw call. I've created a temporary vtest struct for the purposes of testing. It carries the definition. struct vtest{ XMFLOAT3 Vertex; XMFLOAT4 Color; }; Linked to a proper IA abstraction: D3D11_INPUT_ELEMENT_DESC InputElementDesc[] = { { "POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT,

问题 I have overwritten onDragShadow for a DragShadowBuilder like so @Override public void onDrawShadow(Canvas canvas) { super.onDrawShadow(canvas); Bitmap bitmap = InGameActivity.getRandomBitmap(); Rect source = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight()); canvas.drawBitmap(bitmap, source, source, null); } I have verified that the bitmap is not null but when I drag, nothing is showing. Any ideas why? 回答1: If you want to draw the bitmap as is (i.e. you want the whole thing), use: canvas

问题 I have been learning from this site for really long time, but this is actually my first appearance here, that is my first question, I am a civil Engineer and i am writing a software for the design of Retaining Walls, I need to draw figures like these shown below ,to be static or dynamic , (i mean by dynamic that i can change the dimensions of the graph via up-down numeric tool and the changes are visible at the graph,), these should be a ready forms to help the user entering the demotions

问题 When i want to use just part of a bitmap without skewing or rotating it, like the top left fourth, the following works well: src_rect.set(0, 0, bmp_test.getWidth()/2,bmp_test.getHeight()/2); canvas.drawBitmap(src_rect, dst_rectF, paint); This draws just one fourth of the bitmap. However, if i want to rotate or skew just part of a bitmap using a matrix, the following does not work as expected: srcpairs[0] = 0; srcpairs[1] = 0; srcpairs[2] = (float)bmp_test.getWidth()/2; srcpairs[3] = 0;
