  • In Corona SDK the background image always cover other images

    - by user1446126
    I'm currently making a tower defense game with Corona SDK. However, while I'm making the gaming scene, The background scene always cover the monster spawn, I've tried background:toBack() ,however it's doesn't work.Here is my code: module(..., package.seeall) function new() local localGroup = display.newGroup(); local level=require(data.levelSelected); local currentDes = 1; monsters_list = display.newGroup() --The background local bg = display.newImage ("image/levels/1/bg.png"); bg.x = _W/2;bg.y = _H/2; bg:toBack(); --generate the monsters function spawn_monster(kind) local monster=require("monsters."..kind); newMonster=monster.new() --read the spawn(starting point) in level, and spawn the monster there newMonster.x=level.route[1][1];newMonster.y=level.route[1][2]; monsters_list:insert(newMonster); localGroup:insert(monsters_list); return monsters_list; end function move(monster,x,y) -- Using pythagoras to calauate the moving distace, Hence calauate the time consumed according to speed transition.to(monster,{time=math.sqrt(math.abs(monster.x-x)^2+math.abs(monster.y-y)^2)/(monster.speed/30),x=x, y=y, onComplete=newDes}) end function newDes() currentDes=currentDes+1; end --moake monster move according to the route function move_monster() for i=1,monsters_list.numChildren do move(monsters_list[i],200,200); print (currentDes); end end function agent() spawn_monster("basic"); end --Excute function above. timer2 = timer.performWithDelay(1000,agent,10); timer.performWithDelay(100,move_monster,-1); timer.performWithDelay(10,update,-1); move_monster(); return localGroup; end and the monster just stuck at the spawn point and stay there. but, When i comment these 3 lines of code: --local bg = display.newImage ("image/levels/1/bg.png"); --bg.x = _W/2;bg.y = _H/2; --bg:toBack(); The problem disappear Any ideas??Thanks for helping

  • Technical reasons for not having large background images in websites

    - by kees-kist
    Most websites tend to have either a solid color as background, or a small image that is repeated. Why aren't more websites using a large image (such as a photo) as background? I can think of the following reasons: 1) Problems with different screen resolutions. Too small and gaps start to appear on the left and/or right side for higher resolutions, too big and lower resolutions only show part of the image. 2) Bandwidth. Although this is unlikely to be a problem for most websites. Are there any other reasons why such backgrounds are not being used more often?

  • rsvg doesn't render linked images

    - by colinmarc
    I use the python rsvg bindings to render an svg image into cairo and save to file, which mostly works. But if the svg file contains a linked image, like so: <image href="static/usrimgs/tmpDtIKpx.png" x="10" y="10" width="600px" height="400px"></image> the image doesn't show up in the final file (the rest of the svg renders just fine). The relative path is correct based on where the script is running, but I'm guessing there's some problem with the fact that it would normally be a relative URL, not a relative filepath. How do I get around this?

  • Not able to see Images with wmd-editor

    - by KhanS
    I am using wmd editor to enter some text. After entering the text, I am saving it as mark down into the database. While inserting the image, if I save as markdown I am not able to see the image in my aspx page.(Because it down not save image in <img> tab in markdown). If I save the text as html then, I am able to see the image. But another problem with html is, while editing the text I am seeing all tags(such as <code1><p>pre> ) in the wmd-editor.

  • Bubble sort dropped images based on their names

    - by user2259784
    I have written a simple bubble sort function that sort an array of Image objects based on image names. For some reason my function is not swapping the elements of array when needed ( basically new assignment is not working) Here is my code : listOfFiles = event.dataTransfer.files; sortImages(listOfFiles); function sortImages(listOfFiles) { var re = /[0-9]/; var temp; for( var index=0; index < listOfFiles.length ; index++) { for ( var index2=0; index2 < listOfFiles.length-1 ; index2++) { var one = parseFloat(re.exec(listOfFiles[index2].name )); var two = parseFloat(re.exec(listOfFiles[index2+1].name)); console.log(one + " : " + two); if (one > two) { console.log(listOfFiles[index2+1]); console.log(listOfFiles[index2]); //following three lines don't work temp = listOfFiles[index2+1]; listOfFiles[index2+1] = listOfFiles[index2]; listOfFiles[index2] = temp; console.log(listOfFiles[index2+1]); console.log(listOfFiles[index2]); } } } }

The Issue now is when I add a Texture the cube then flickers(with the texture on it) and disappears leaving the camera preview upon further research i discovered that the cube with the texture was disappearing behind the Camera preview. My Question is has anyone else had this issue and if yes what approach did you take to solve this. Heres another strange Issue when i take a print screen the cube is on-top of the camera Preview

  • MainMenu with Images

    - by j-t-s
    I have a MainMenu in my app and I would like to have little icons relevant to the Item in each menu. But the MainMenu control does not support this. I would use the MenuStrip control, though that is a pretty ugly option in my opinion. Does anybody have any suggestions? Are there any free/open source alt's out there, or would it be easy/possible to implement that feature into the existing MainMenu control?

  • Why does Android allocate more memory than needed when loading images

    - by Simon
    Folks, I don't think that this is a duplicate and is NOT one of those how do I avoid OOMs questions. This is a genuine quest for knowledge so hold off on those down votes please... Imagine I have a JPEG of 500x500 pixels. I load it as ARGB_8888 which is as "bad as it gets". I would expect Android to allocate 500x500x4 bytes = a little under 1MB however, look at a heap dump and you will see that Android allocates significantly more, often factors of 5-10 times greater. You frequently see questions on here about OOMS where the stack trace shows a heap request of say 15MB and it is ALWAYS much larger than is required simply to hold the bytes of the image. The OP usually catches some downvotes then is bombarded with stock answers and comments about using less memory (thanks Romain!) and in scaling. I think there is more than meets the eye here. Anybody know why this is? If there is no apparent answer, I will put together an SSCCE if it helps. PS. I assume that JPEG vs PNG etc is irrelevant since we're talking about the memory usage of the backing bitmap which is simply x times y times BPP - or am I being slow?

  • java best way to transfer images

    - by d.raev
    I have a application that reads a PDF, transform the content to collection of TIF files, and send them to Glass Fish Server for saving. Usually there are 1-5 pages and it works nice, but when I got a input file with 100+ pages... it throws error on the transfer. Java heap space at java.util.Arrays.copyOf(Arrays.java:2786) at java.io.ByteArrayOutputStream.write(ByteArrayOutputStream.java:94) Putting more resources is not a good option in my case, so I m looking for a way to optimize it somehow. I store the data in: HashMap<TifProfile, List<byte[]> Is there a better way to store or send them ? EDIT I did some tests and the final collections for PDF with 80 pages has size over 280mb (240 tiffs with different settings inside)

    I'm trying to get multiple image paths from my database in order to display them, but it currently doesn't work. Here's what i'm using: def get_image(self, userid, id): image = meta.Session.query(Image).filter_by(userid=userid) permanent_file = open(image[id].image_path, 'rb') if not os.path.exists(image.image_path): return 'No such file' data = permanent_file.read() permanent_file.close() response.content_type = guess_type(image.image_path)[0] or 'text/plain' return data I'm getting an error regarding this part: image[id].image_path What i want is for Pylons to display several jpg files on 1 page. Any idea how i could achieve this?

  • Execute jQuery code when images have loaded from external resource

    - by Nick Swan
    Hi all, I'm getting users profile pictures from Facebook so their loading time varies quite a lot. When they have loaded I want to resize them. I have the resizing code working OK, but cannot get the actual code to execute reliably at the right time. According to the info I've found this should work: $('.userPic').load(function () { ... code to resize pictures }); But it doesn't seem 100% reliable. Any other hints or tips? Thanks Nick Swan

  • Alt for images in JasperReports

    - by Aviator
    Hello all, While putting an image element in PDF report, how can we give the alt description or similar kind of description for that image? The idea is to read the description when some screen reader is used to read the PDF. Currently, the reader (JAWS) says just 'graphic' when encountering an image in the PDF. Thanks!

  • How to systematically generate images from data?

    - by adamvickers
    I work for a performing arts nonprofit. We have seating charts for each of the theaters we work with; each seating chart shows the number of sections, the shape of each section, and the number of rows in each section. We'd like to create dynamic seating charts based on this info. We'd like them to look/feel kinda like this: http://www.fansnap.com/tickets/177754-on. But the tricky part is we'd like to be able to store all the info about each theater (the section names, shape/size of each section, and number of rows in each section) as data and then build a system that reads this data and uses it to create a dynamic map. I'm a life-long web developer, but I don't have have any experience with a difficult graphics problem like this. I realize it's a complex problem and I don't expect anyone to give me a complete answer here, but I would love direction on where I should be looking for more info. Is what I'm describing possible? Does this sort of technique have a name? Where can I learn more about how to accomplish this? What software should I use? Any info would be helpful.

  • Memory leaks getting sub-images from video (cvGetSubRect)

    - by dnul
    Hi, i'm trying to do video windowing that is: show all frames from a video and also some sub-image from each frame. This sub-image can change size and be taken from a different position of the original frame. So , the code i've written does basically this: cvQueryFrame to get a new image from the video Create a new IplImage (img) with sub-image dimensions ( window.height,window.width) Create a new Cvmat (mat) with sub-image dimensions ( window.height,window.width) CvGetSubRect(originalImage,mat,window) seizes the sub-image transform Mat (cvMat) to img (IplImage) using cvGetImage my problem is that for each frame i create new IplImage and cvMat which take a lot of memory and when i try to free the allocated memory I get a segmentation fault or in the case of the CvMat the allocated space does not get free (valgrind keeps telling me its definetly lost space). the following code does it: int main(void){ CvCapture* capture; CvRect window; CvMat * tmp; //window size window.x=0;window.y=0;window.height=100;window.width=100; IplImage * src=NULL,*bk=NULL,* sub=NULL; capture=cvCreateFileCapture( "somevideo.wmv"); while((src=cvQueryFrame(capture))!=NULL){ cvShowImage("common",src); //get sub-image sub=cvCreateImage(cvSize(window.height,window.width),8,3); tmp =cvCreateMat(window.height, window.width,CV_8UC1); cvGetSubRect(src, tmp , window); sub=cvGetImage(tmp, sub); cvShowImage("Window",sub); //free space if(bk!=NULL) cvReleaseImage(&bk); bk=sub; cvReleaseMat(&tmp); cvWaitKey(20); //window dimensions changes window.width++; window.height++; } } cvReleaseMat(&tmp); does not seem to have any effect on the total amount of lost memory, valgrind reports the same amount of "definetly lost" memory if i comment or uncomment this line. cvReleaseImage(&bk); produces a segmentation fault. notice i'm trying to free the previous sub-frame which i'm backing up in the bk variable. If i comment this line the program runs smoothly but with lots of memory leaks I really need to get rid of memory leaks, can anyone explain me how to correct this or even better how to correctly perform image windowing? Thank you

  • Threads to make video out of images

    - by masood
    updates: I think/ suspect the imageIO is not thread safe. shared by all threads. the read() call might use resources that are also shared. Thus it will give the performance of a single thread no matter how many threads used. ? if its correct . what is the solution (in practical code) Single request and response model at one time do not utilizes full network/internet bandwidth, thus resulting in low performance. (benchmark is of half speed utilization or even lower) This is to make a video out of an IP cam that gives a new image on each request. http://149.5.43.10:8001/snapshot.jpg It makes a delay of 3 - 8 seconds no matter what I do. Changed thread no. and thread time intervals, debugged the code by System.out.println statements to see if threads work. All seems normal. Any help? Please show some practical code. You may modify mine. This code works (javascript) with much smoother frame rate and max bandwidth usage. but the later code (java) dont. same 3 to 8 seconds gap. <!DOCTYPE html> <html> <head> <script type="text/javascript"> (function(){ var img="/*url*/"; var interval=50; var pointer=0; function showImg(image,idx) { if(idx<=pointer) return; document.body.replaceChild(image,document.getElementsByTagName("img")[0]); pointer=idx; preload(); } function preload() { var cache=null,idx=0;; for(var i=0;i<5;i++) { idx=Date.now()+interval*(i+1); cache=new Image(); cache.onload=(function(ele,idx){return function(){showImg(ele,idx);};})(cache,idx); cache.src=img+"?"+idx; } } window.onload=function(){ document.getElementsByTagName("img")[0].onload=preload; document.getElementsByTagName("img")[0].src="/*initial url*/"; }; })(); </script> </head> <body> <img /> </body> </html> and of java (with problem) : package camba; import java.applet.Applet; import java.awt.Button; import java.awt.Graphics; import java.awt.Image; import java.awt.Label; import java.awt.Panel; import java.awt.TextField; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.net.URL; import java.security.Timestamp; import java.util.Date; import java.util.concurrent.TimeUnit; import java.util.concurrent.atomic.AtomicBoolean; import javax.imageio.ImageIO; public class Camba extends Applet implements ActionListener{ Image img; TextField textField; Label label; Button start,stop; boolean terminate = false; long viewTime; public void init(){ label = new Label("please enter camera URL "); add(label); textField = new TextField(30); add(textField); start = new Button("Start"); add(start); start.addActionListener(this); stop = new Button("Stop"); add(stop); stop.addActionListener(this); } public void actionPerformed(ActionEvent e){ Button source = (Button)e.getSource(); if(source.getLabel() == "Start"){ for (int i = 0; i < 7; i++) { myThread(50*i); } System.out.println("start..."); } if(source.getLabel() == "Stop"){ terminate = true; System.out.println("stop..."); } } public void paint(Graphics g) { update(g); } public void update(Graphics g){ try{ viewTime = System.currentTimeMillis(); g.drawImage(img, 100, 100, this); } catch(Exception e) { e.printStackTrace(); } } public void myThread(final int sleepTime){ new Thread(new Runnable() { public void run() { while(!terminate){ try { TimeUnit.MILLISECONDS.sleep(sleepTime); } catch (InterruptedException ex) { ex.printStackTrace(); } long requestTime= 0; Image tempImage = null; try { URL pic = null; requestTime= System.currentTimeMillis(); pic = new URL(getDocumentBase(), textField.getText()); tempImage = ImageIO.read(pic); } catch(Exception e) { e.printStackTrace(); } if(requestTime >= /*last view time*/viewTime){ img = tempImage; Camba.this.repaint(); } } }}).start(); System.out.println("thread started..."); } }

  • Werid onclick behavior of images on home screen widget

    - by kknight
    I wrote a home screen widget with one image on it. When the image is clicked, browser will be opened for a url link. Generally, it is working. But a weird thing is that, when I click background, then click the picture, the browser will not be open. Until I click the second time on the picture, the browser opens. The steps to reproduce is below: Click on the home screen widget background. Click on the image on the home screen. The browser is not opened. Click on the image again. The browser is opened. If I didn't click on the background, the image will react to click very well, i.e. browser will be open when the image is clicked the first time. The widget XML file is as below: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/widget" android:layout_width="320dip" android:layout_height="200dip" android:background="@drawable/prt_base" > <ImageView android:id="@+id/picture1" android:layout_width="134dip" android:layout_height="102dip" android:layout_marginLeft="62dip" android:layout_marginTop="6dip" android:scaleType="center" android:src="@drawable/picture1" /> </RelativeLayout> The code to set OnClick on the picture1 ImageView is as below: defineIntent = new Intent(Intent.ACTION_VIEW, Uri .parse("http://www.google.com")); pendingIntent = PendingIntent .getActivity(context, 0 /* no requestCode */, defineIntent, 0 /* no flags */); updateViews.setOnClickPendingIntent( picId, pendingIntent); Anyone knows what's wrong? Thanks.

  • iPhone Scroll images horizontally like in AppStore

    Hi there, I was wondering if it's possible to create a HTML div container with some CSS magic that shows a horizontal scrollbar like the one with the screenshots on the iTunes preview on the web. I want this to work in Safari on the iPhone. e.g. http://itunes.apple.com/app/super-monkey-ball/id281966695?mt=8 I would like to use that to display thumbnails in an UIWebView on iPhone. I experimented with the overflow css property but didn't get it to work. Thanks for your replies.

  • iPhone transparent images rendering poorly

    - by alku83
    I'm developing an iPad application. I have been provided with a PNG image that contains some transparency - basically a drop shadow. The problem I'm having is that this is rendering poorly within the application, both on the device and in the sim. I can't provide the whole image but I've made up some samples to illustrate. The first is how the image appears in the PSD (correctly that is). The second is how it appears on the device. You can see that the strip of shadow in the middle of the image is distinctly more yellow and poorly looking. Any ideas what I'm doing wrong?
