How to pixelate a binary (P6) PPM file

问题 I am struggling to pixelate an image which is made up of RGB values stored in a binary (P6) PPM file. The steps to pixelate the image are as follows: Read in the binary data and store it in a 1-dimensional array Iterate through the data stored in this array, in cells of size 'c' (row x columns). This variable 'c' can be changed by the user, but for this program it's currently set to int c = 4; meaning it iterates through pixel data in block dimensions of 4 x 4 Now find the average colour

问题 Top answer in this link How to pixelate a square image to 256 big pixels with python? uses PIL to pixelate image. Converting image from PIL to cv2.Mat is possible but I'm not allowed to use other library, and I couldn't find any good method using opencv. Is there any way to pixelate image using OpenCV library only in Python? Any sample image is fine. Solution with pixel size parameter that I can control for later adjustment would be very appreciated. 回答1: EDIT^2 With the help of himself, I

问题 so I am having a few issues with this program used to pixelate an image. One issue is that I get a "Stack around the variable 'pixArray' was corrupted" and then, when I click continue after breaking it gives the error in the title. I'm not sure if it is acceptable to use pastebin, but I'll use it for the sake of having a "short" post. The Code The Image Being Used Also, when it runs through, all of the pixelated squares are one pixel too short on the left and top of the squares. It is just

问题 Is it possible or is there a trick to make a background pixelated like the one in the image attached? I use a background image, but as you can see it doesn't scale and it flashs on page scrolling. Now I have CSS thanks to vlcekmi3: background-color: white; background-image: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black), linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%, black); background-size:100px 100px; background-position

PHP image pixelate?

由 霸气de小男生 提交于 2019-12-04 09:54:42
问题 I need to make this effect with php. I know that there is IMG_FILTER_PIXELATE in PHP image filter. But I need it to be smoother and embossed? like in this image: This effect will make any image uploaded by user become pixelated and the edge of the picture become red (I know IMG_FILTER_EDGEDETECT but I don't know how to use it to change edge color). I have no idea how to do this. 回答1: As the last answer was theoretical and seemed to be not enough, I've created a practical example: Note: This

How can I pixelate a jpg with java?

问题 I'm trying to pixelate a JPEG with Java 6 and not having much luck. It needs to be with Java - not an image manipulation program like Photoshop, and it needs to come out looking old school - like this: Can anybody help me? 回答1: Using the java.awt.image (javadoc) and javax.imageio (javadoc) APIs, you can easily loop through the image's pixels and perform the pixelation yourself. Example code follows. You will need at least these imports: javax.imageio.ImageIO , java.awt.image.BufferedImage ,
