Usually use SLR or cell phone pixel highs, the photos will be very beautiful, but at the same time the size of the photo is also a bit big oh! If we upload to the site is slow, but also seems too big, a bit redundant. So today I'm going to teach you to try to change the size of the picture without damaging the quality of the picture.

This is a technique presented in the book "Professional Processing techniques for digital photography", the author of Scott Kelby, who describes a technique used by master Jim Divitale, a digital photographer. This technique is said to be able to increase the digital camera image to the entire poster size, but with the naked eye can hardly see the quality of the image. Is that so? Let's take a look.
1. Start Photoshop, and then open a
In this paper, the thinkphp watermark function is introduced to repair PNG transparent watermark and to increase the quality of JPEG image can be adjusted. Share to everyone for your reference. The implementation method is as follows:
TP comes with the picture class, has the function of adding watermark to the picture.Here are the perfect:1. PNG watermark Transparency2. Watermark

Bitmapconfig (Bitmap.Config.RGB_565)So what does this Bitmap.Config.RGB_565 mean?Large pictures in Android generally have to be compressed to display, otherwise prone to oom, generally we compress only attention to its size, in fact, in addition to the size, the impact of a picture

Absrtact: We propose an algorithm to remove motion blur from a single image. Our method uses a uniform probabilistic model for estimating the convolution kernel and for the clear image in the process of fuzzy image calculation. We analyze the causes of the artificial traces that usually exist in the current blur method, and then introduce some new terms in our probabilistic model. These terms include the spatial stochastic model of fuzzy image noise, and the new local smoothing priori knowledge.
Using the tool Thumbnailator, it is said that Thumbnailator is a very good image open source tool, easy to use. But not carefully, I just need to compress the picture, so that it occupies less space.
