tiling

问题 I'm having trouble finding an answer as to why the tile sheets I am making for our tile maps create vertical white lines and jittery horizontal lines while moving around on screen, using libGDX. Here is a video showing the white vertical lines: https://www.youtube.com/watch?v=34V64WacMo4 Here is one showing the horizontal jittery lines: https://www.youtube.com/watch?v=LiozBZzxmy0 For comparison, here is a project I worked on earlier this year without GDX. You can see the tilemap moves

问题 When its translated in an integral value (1,2,3, etc....), there are no black lines in-between the tiles, it looks fine. But when it's translated to a non-integral (1.1, 1.5, 1.67), there are small blackish lines between each tile (I'm imagining that it's due to subpixel rendering, right?) ... and it doesn't look pretty =P So... what should I do? This is my image-loading code, by the way: bool Image::load_opengl() { this->id = 0; glGenTextures(1, &this->id); this->bind(); // Parameters...

问题 I need some help in converting a 2X2 matrix to a 4X4 matrix in the following manner: A = [2 6; 8 4] should become: B = [2 2 6 6; 2 2 6 6; 8 8 4 4; 8 8 4 4] How would I do this? 回答1: A = [2 6; 8 4]; % arbitrary 2x2 input matrix B = repmat(A,2,2); % replicates rows & columns but not in the way you want B = B([1 3 2 4], :); % swaps rows 2 and 3 B = B(:, [1 3 2 4]); % swaps columns 2 and 3, and you're done! 回答2: In newer versions of MATLAB (R2015a and later) the easiest way to do this is using

问题 I'm looking for a way to Merge some PNG tile images into a big image. So I search and found some links. This is not answered properly. This is not tiling, it's good for overlaying images and this is not using WPF. So I'm making this question. Problem Definition: I have 4 PNG images. I want to merge them into a single PNG image, like this ------------------- | | | | png1 | png2 | | | | ------------------- | | | | png3 | png4 | | | | ------------------- Question: What is the best and efficient

问题 I have been trying to make an infinite scrolling 2D background in Unity using a quad to display a Texture. My idea was to change the offset of the quad depending on the player's position. For some reason when I change the offset my image does not repeat properly and once an offset of 2 has been reached completely disappears. An image of 3 different x offset values on my texture If anyone knows how to fix this if you could get back to me it would be much appreciated. 回答1: Select the original

问题 I am trying to tile an image(16x16) over a Rectangle area of dimensions width=1000, height=16 using TextureBrush to get a strip like UI. Rectangle myIconDrawingRectangle = new Rectangle(x, y, 1000, 16); using (TextureBrush brush = new TextureBrush(myIcon, WrapMode.Tile)) { e.Graphics.FillRectangle(brush, myIconDrawingRectangle ); } When I draw with x=0, y=0 tiling happens as expected starting from (0,0). When I draw with x=0, y=50 tiling starts at (0,50) but the the painting rectangle does

问题 I am searching for a way using Tensorflow to extract all of the sub-elements except for the one corresponding to the tensor's index. (eg. if looking at index 1 then only sub-elements 0 and 2 are present) Very similar to this approach using Numpy. Here's some example code to create a tiled tensor and a boolean mask: import tensorflow as tf import numpy as np _coordinates = np.array([ [1.0, 7.0, 0.0], [2.0, 7.0, 0.0], [3.0, 7.0, 0.0], ]) verts_coord = _coordinates n = verts_coord.shape[0] mat

问题 I have three BitmapImages that I would like to stitch together to create a composite image. The three images to be stitched together are aligned in the following way: The images are of a type System.Windows.Media.Imaging.BitmapImage. I have looked at the following solution, but it uses System.Drawing.Graphics to perform stitching. I find it unintuitive to convert my BitmapImage to System.Drawing.Bitmap everytime I want to stich them together. Is there a simple way to stitch three images of

问题 I have a requirement to insert Content into the middle of the page in a PDF. The Content may be a Dynamic Table or an Image. My Concept was to first split the PDF into 2 parts, then get the new Content that is to be added and append by replacing a place holder field. the Splitting is called Tiling as per IText and here is an example for the same. http://itextpdf.com/examples/iia.php?id=116 The Code above has 2 drawbacks: 1. It splits the page into 16 parts. but that is part of the example.

问题 I am looking for some pointers to algorithms that should allow to tile with no overlap different size rectangles. Given a set of different sized rectangles, tile them on an area of size H x W with no overlap. The objective would be to maximize the space used or conversely - minimize area of gaps. If there is not enough space, proceed on the second area of the same size and so on. It is assumed that each rectangle's width and height are smaller than respective dimensions of the tiling area.
