tiling

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. Still i cant figure out a way to split the file into 2 parts only. 2. secondly the split page is

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 way of doing this (The resulting image must be PNG)? // Loads the images to tile (no need to specify

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. Rectangles are not rotated or otherwise transformed - i.e. their sides are either horizontal or vertical.

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. Select the original Texture not the GameOBject. 1 . Change Texture Type to Texture . 2 . Change Wrap Mode to Repeat . 3 . Click

I was trying to tile an array where each index is multi-diminsional. I then remove the i'th sub element from each index. For example, starting with this array: >>> a = np.array([[ 1. , 7. , 0. ], [ 2. , 7. , 0. ], [ 3. , 7. , 0. ]]) >>> a = np.tile(a, (a.shape[0],1,1)) >>> print a array([[[ 1. , 7. , 0. ], [ 2. , 7. , 0. ], [ 3. , 7. , 0. ]], [[ 1. , 7. , 0. ], [ 2. , 7. , 0. ], [ 3. , 7. , 0. ]], [[ 1. , 7. , 0. ], [ 2. , 7. , 0. ], [ 3. , 7. , 0. ]]]) Desired output: b = np.array([[[ 2. , 7. , 0. ], [ 3. , 7. , 0. ]], [[ 1. , 7. , 0. ], [ 3. , 7. , 0. ]], [[ 1. , 7. , 0. ], [ 2. , 7. , 0. ]]

I would like to create a 'graph paper' look to the Bitmap I am drawing via a Canvas, and trying to figure out the best way to do this. I can't pass a source Bitmap containing the graph paper background to the Canvas constructor, as I am getting the Canvas in a SurfaceView via the .lockCanvas() call. Some solutions I've tried: I've tried implementing this solution in my SurfaceView's Thread.run(), but the issue I believe is when the BitmapDrawable is converted to a Bitmap... it loses the tiling properties. canvas = mSurfaceHolder.lockCanvas(null); BitmapDrawable TileMe = new BitmapDrawable
