stretching for dummies

Bolg is not just an original article. Of course there are somePseudo-originalThe article, the pseudo-good or bad, the selection of the article, has been plagued by new users such as me. Many of my friends copied some popular articles and made changes, and then posted them on their websites in a rush. Finally, Baidu only recorded the homepage, it is very difficult, but google is doing better in this regard, and the record is OK. Here, Chen tofu also shares the operating ideas and techniques of hi

I feel sick when I see the dummies of my dreams !" Lu Fei: suo long, this is definitely not a fight! Have you ever wondered why this is definitely not a fight? Why not defend your dreams? Lu Fei knew that they were not a means to defend their dreams, so he

I really want to spend a lot of time studying how Linux works documents, only a few Linux developers and enthusiasts can access the Internet and achieve multimedia.======================================The features you need can be fully met in windows. I don't know why you have to look for Linux. If you really want to study it, be humble.A little. Windows is like a dummies camera. It's very easy to use. Linux is a professional ca

how did you do it? There are hundreds of thousands of combs, but there are hundreds of thousands of dollars. Where do you come with so much money ?" LV Bu smiled and said, "What is it about weak meat? Where is the weakness? All on this head! Therefore, every business-minded person will look at a group of dummies and dummies. Dong Zhuo will be like this, so will Lu Bu. He used his monthly salary of Yuan as

When adjusting the overall effect of a graphic in cad, stretching is a common method, most of which is stretching the rectangle. To change the width or size of a rectangle, you can use stretching to resolve it. First, before you explain, emphasize the two key points of stretching: 1. When

}; 2.1 EXACT_FIT EXACT_FIT is completely projected to the full screen. This is the perfect thing for programs and fine arts, but it will be stretched. The above is the original image of 960x540. I have added a reference object to the four corners. The total figure is an image. Assume that the resolution of the target mobile phone is 1136x500 (the actual resolution does not exist). Using EXACT_FIT is the following effect: In fact, it is acceptable to stretch the background. The ma

Forstate:uicontrolstatenormal ];//Add button [Self.view Addsubview:button];Run:As you can see, the effect is very poor. The reason is very simple, because the original size is 24x60, and now the entire picture is stretched to 150x50, the more serious is the 4 corners of the picture.Some people may immediately think of a solution, you call the artist to enlarge the picture is not good, how to stretch all right. Yes, it's a solution, but it's not recommended. The reason is simple: 1. The picture

in the upper right corner, and put it in the position (960,640. You do not need to consider visibleSize or anything in cocos2d. In reality, the resolution of a mobile phone cannot be a multiple of 960x640. And we need to display it in full screen, so we have the third parameter to specify the specific projection method. There are currently five resolutionpolicies for cocos2d: enum class ResolutionPolicy{ EXACT_FIT, NO_BORDER, SHOW_ALL, FIXED_HEIGHT, FIXED_WIDTH}; 2.1 EXACT_FIT

increased. Here combined with the above (2) to set the variable area for the whole picture, can solve this problem, see the principle of seamless mappingThe sample code is as follows:UIImage(named:"tile")let resizeImage = image?.resizableImageWithCapInsets(UIEdgeInsetsZero)self.bkImageView.image = resizeImage2.2.2 Asset catalogs Way (recommended)Xcode provides the Asset catalogs way to manage the image resources, Asset catalogs provides a visual interface to set the variable area of the picture

. drawimage ( BMP, 10, 10 );Rect (130, 10, BMP. getwidth (), BMP. getheight ());Graphics. drawimage ( BMP, rect ); It should be noted that the image also provides the getthumbnailimage method to obtain a thumbnail pointer. After drawimage is called, the thumbnail can be displayed, which is extremely useful in image preview. For example, the following code: Graphics graphics (PDC-> m_hdc );Image image (L "sunflower.jpg ");Image * pthumbnail = image. getthumbnailimage (50, 50, null,

The English name of histogram equalization is histogram equalization.Image Contrast enhancement can be divided into two types: direct contrast enhancement and indirect contrast enhancement. Histogram stretching and histogram equalization are two of the most common indirect contrast enhancement methods. Histogram stretching is to adjust the histogram by contrast stretchi
