In the layout file of Android, dp is often used as the width and height of the control, but in Java code, the size unit obtained by calling the getWidth () methodThe difference is pixel px. The two units have obvious differences: dp is related to the screen density, while px is irrelevant to the screen density. Therefore, twoMutual conversion between users. The sample code is as follows:Public int Dp2Px (Context context, float dp ){Final float scale =

Format ("font width: {0}, Height: {1}", Sizef.width, Sizef.height)); Graphics. Dispose ();Use G. MeasureString () obtainedThe width of the characters measured with measurestring is always larger than the actual width, and as the length of the character increases, the gap between the actual width and the width of the measurement is increasing.

When writing a raster renderer, you need to load a picture to get pixels for texture interpolation, and try several methods to find out that the following comparisons are simple, efficient and acceptableTexture2d is a class of my own definition, where M_pixelbuffer is a dynamic two-dimensional array, with each element ZCFLOAT3 (the custom type is used to hold the color RGB values).1#include"LoadBitmap.h"2#include 3#include 4 5#include 6#include 7#include 8 9 #pragmaComment (lib, "Gdiplus.lib")Te

When a floating element is adjacent to a non-floating element, this 3-pixel Bug occurs, and it is offset by 3 pixels. As long as the hasLayout of IE is triggered, non-floating elements have a layout. Therefore, you can fix this problem by using the hack rule unique to IE6 to write a style for it separately: _ Zoom: 1; Margin-left: value; _ Margin-left: value-3px; Zoom is one of the Layout conditions triggered by IE, because it is a CSS rule uniq

Android is self-adapting to screen size and density. Android provides the following folders to store image resources in order to ensure app interface effects on different screens. Different folders correspond to different pixel density picture resourcesDRAWABLE-LDPI:120DPI around the screen (low density)Drawable-mdpi:160dpi or so screen (medium density)The drawable-tvdpi:213dpi screen (medium high density) is introduced primarily in api13 to optimize

(120/160/240)In Android, 1pt is roughly equal to 2.22SP. above for reference, if the UI can provide the best design in SP, and if there is no concept of SP in the design, the developer can also take approximate values by appropriate conversion. Android supports all of the following units.PX (pixels): The point on the screen.In (inches): unit of length.MM (mm): unit of length.PT (lb): 1/72 inches.DP (density-independent pixels): An abstract unit based on screen density. 1DP = 1px on a monitor 16

Always want to write an image processing of their own software. On the network to find a variety of image processing technology articles. But find often not advanced theory, is to use C + + and other languages written out of the routine, very inconvenient. In fact, most of the time, I want to find a description, or pseudo code, both for understanding, but also conducive to rewriting the version of any language. Recently, I have learned some of the image processing of knowledge to write a imageca
