Article transferred from: http://blog.csdn.net/zpf03/article/details/5903484 During this time, I developed an image recognition project based on wince6.0 + 6410, using the Development Board of youjian hengtian. This development board has an ov9650 camera connection port, but one of the biggest problems is that the image obtained by the camera is too small and only 320*240 images can be seen. I need 1280*1024 images, therefore, it can only be modified. If you want the driver to provide an interf

Php uses regular expressions to process values that are not required in strings. Today, when collecting images from the Momo website, the resolution of the images will be changed to 320*480, and the original images contain pixel information. For example, the clear Hut (320 today, when collecting images on Mo's Web site, because I will eventually change the image resolution to 320*480, the original image con

based on screen resolution only. That is, the device is based on the screen resolution. This is also the source of the commonly seen VGA class name:Differentiate different devices according to different screen resolutions, such as some common names: QVGA: 240*320 Quarter VGA One-fourth meaning (for a quarter) HVGA: 320*480 Half size VGA meaning one-second (1 = a) VGA: 480*640 T

Php makes good use of regular expressions to process the Value nbsp, in the end, I will change the image resolution to 320*480, and the original image contains pixel information. Nbsp; e. g.: clear cabin (320*480) Wallpaper nbsp; in the end, php makes good use of regular expressions to process the values required in strings. Today, when collecting images from the Momo website, the resolution of the imag

These two standards have been implemented through code, with the official code attached here: public camera.size getoptimalpreviewsize (list When loading the preview screen, you need to consider the dimensions (getsupportedpreviewsizes) supported by camera and the Surfaceview dimensions (layout_width/layout_height) that load the preview, and in the preview phase, The re

Android divides the screen size into four types: small, normal, large, xlarge;The screen density is divided into: low (LDPI), Medium (MDPI), High (hdpi), Extra High (xhdpi), and the relationship between each screen density is as follows: Density name reference value for density (DPI) Relationship the corresponding screen resolution xxxhdpi 640dpi xxhdpi 480dpi xhdpi 320dpi

Today, when collecting images from the Momo website, the resolution of the images will be changed to 320*480, and the original images contain pixel information. For example, clear cottage (320*480) Wallpaper So what should I do if I want to leave the "Clear cottage Wallpaper? First, we should immediately think that we should first find the string and remove it. Well, first of all, I thought so too. I define

resources in assets or no-dpi can also avoid high peak memory caused by scaling. If your program often loads an image, but if you want to continue using it, you can also directly use: try {// load big memory data} catch (java. lang. outOfMemoryError e) {// TODO alternative solution} test: 1 place image A in no-dpi, the memory is loaded only once, and no scaling is performed. 2 only in drawable-hdpi: put A-PNG Image, 2.1 when the test machine is avd2.3.3-320-
