  • How to make image bigger than the screen to be slideable in the screen in monogame for windows phone 8?

    - by Moses Aprico
    (Idk if my title is correct, because when I google it, there is no related result I guess) I am not sure how to explain it correctly, but I am making a plain 2D, tile based, tactic game in windows phone 8 using monogame. I want to make my map is "slideable". With "slidable" I mean I can draw larger images (in total) than my screen and then slide it so I can view a certain area of the drawn images Example : I have a screen which dimension is 1280x720. I have a 1500x1500px image, which consists of 15 tiles, which is 100x100px each, which each tiles is redrawn each times the "Draw" is called. If the image is larger than the screen, the displayed area will be trimmed and of course, making a 220x780px area that is unseenable. The only way to see all of it is through "sliding" the screen around, so I can see all the area. My question is : How to make that happen? Because in default, the screen is unslideable and the image remains trimmed. Sorry if my question and explanation is not clear enough. Clarify it as much as you like. Thank you.

  • Error -12 hibernation image. Not enough free memory (sometimes)

    - by user99306
    I am having a problem with hibernation in Ubuntu 12.10, it had worked fine in 12.04. When I try and hibernate it sometimes appears to hibernate throws up an error and returns me to the desktop. The error I get is this: PM: Creating hibernation image: PM: Need to copy 375021 pages PM: Normal pages needed: 117957 + 1024, available pages: 110205 PM: Not enough free memory PM: Error -12 creating hibernation image Now I understand what the error means, but it doesn't make sense. My swap file is 5GB and is seldom ever used as I have 4GB of RAM. I know it is recommended to have 1.5 times more swap than RAM etc, but space doesn't seem to be the problem, despite the error. For example, I rarely use more than about 25%-30% of my RAM, yet still have the problem above. Moreover on a fresh boot and login, with no programs open and using only about 12% of RAM, I can get the above error - yet at other times I can hibernate whilst using 25% of my RAM. Also if I keep trying to hibernate, it eventually does after throwing up the above error four or five times. A successful hibernation looks like this: PM: Creating hibernation image: PM: Need to copy 295511 pages PM: Normal pages needed: 95534 + 1024, available pages: 132627 Is there some setting that I need to tweak or something I need to do before hibernating to avoid this problem? I guess the question could be better interpreted as: Is there some way of safely flushing the buffers and the cache before hibernation? Other than attempting to hibernate several times until it is successful! Thanks in advance.

  • django/python: is one view that handles two separate models a good idea?

    - by clime
    I am using django multi-table inheritance: Video and Image are models derived from Media. I have implemented two views: video_list and image_list, which are just proxies to media_list. media_list returns images or videos (based on input parameter model) for a certain object, which can be of type Event, Member, or Crag. It alters its behaviour based on input parameter action, which can be either "edit" or "view". The problem is that I need to ask whether the input parameter model contains Video or Image in media_list so that I can do the right thing. Similar condition is also in helper method media_edit_list that is called from the view. I don't particularly like it but the only alternative I can think of is to have separate logic for video_list and image_list and then probably also separate helper methods for videos and images: video_edit_list, image_edit_list, video_view_list, image_view_list. So four functions instead of just two. That I like even less because the video functions would be very similar to the respective image functions. What do you recommend? Here is extract of relevant parts: http://pastebin.com/07t4bdza. I'll also paste the code here: #urls url(r'^media/images/(?P<rel_model_tag>(event|member|crag))/(?P<rel_object_id>\d+)/(?P<action>(view|edit))/$', views.video_list, name='image-list') url(r'^media/videos/(?P<rel_model_tag>(event|member|crag))/(?P<rel_object_id>\d+)/(?P<action>(view|edit))/$', views.image_list, name='video-list') #views def image_list(request, rel_model_tag, rel_object_id, action): return media_list(request, Image, rel_model_tag, rel_object_id, action) def video_list(request, rel_model_tag, rel_object_id, action): return media_list(request, Video, rel_model_tag, rel_object_id, action) def media_list(request, model, rel_model_tag, rel_object_id, action): rel_model = tag_to_model(rel_model_tag) rel_object = get_object_or_404(rel_model, pk=rel_object_id) if model == Image: star_media = rel_object.star_image else: star_media = rel_object.star_video filter_params = {} if rel_model == Event: filter_params['media__event'] = rel_object_id elif rel_model == Member: filter_params['media__members'] = rel_object_id elif rel_model == Crag: filter_params['media__crag'] = rel_object_id media_list = model.objects.filter(~Q(id=star_media.id)).filter(**filter_params).order_by('media__date_added').all() context = { 'media_list': media_list, 'star_media': star_media, } if action == 'edit': return media_edit_list(request, model, rel_model_tag, rel_model_id, context) return media_view_list(request, model, rel_model_tag, rel_model_id, context) def media_view_list(request, model, rel_model_tag, rel_object_id, context): if request.is_ajax(): context['base_template'] = 'boxes/base-lite.html' return render(request, 'media/list-items.html', context) def media_edit_list(request, model, rel_model_tag, rel_object_id, context): if model == Image: get_media_record = get_image_record else: get_media_record = get_video_record media_list = [get_media_record(media, rel_model_tag, rel_object_id) for media in context['media_list']] if context['star_media']: star_media = get_media_record(star_media, rel_model_tag, rel_object_id) star_media['starred'] = True else: star_media = None json = simplejson.dumps({ 'star_media': star_media, 'media_list': media_list, }) return HttpResponse(json, content_type=json_response_mimetype(request)) #

  • Help with design structure choice: Using classes or library of functions

    - by roverred
    So I have GUI Class that will call another class called ImageProcessor that contains a bunch functions that will perform image processing algorithms like edgeDetection, gaussianblur, contourfinding, contour map generations, etc. The GUI passes an image to ImageProcessor, which performs one of those algorithm on it and it returns the image back to the GUI to display. So essentially ImageProcessor is a library of independent image processing functions right now. It is called in the GUI like so Image image = ImageProcessor.EdgeDetection(oldImage); Some of the algorithms procedures require many functions, and some can be done in a single function or even one line. All these functions for the algorithms jam packed into ImageProcessor can be pretty messy, and ImageProcessor doesn't sound it should be a library. So I was thinking about making every algorithm be a class with a shared interface say IAlgorithm. Then I pass the IAlgorithm interface from the GUI to the ImageProcessor. public interface IAlgorithm{ public Image Process(); } public class ImageProcessor{ public Image Process(IAlgorithm TheAlgorithm){ return IAlgorithm.Process(); } } Calling in the GUI like so Image image = ImageProcessor.Process(new EdgeDetection(oldImage)); I think it makes sense in an object point of view, but the problem is I'll end up with some classes that are just one function. What do you think is a better design, or are they both crap and you have a much better idea? Thanks!

  • Precise exposition of an image for set number of frames (Vsync?)

    - by Istrebitel
    I need to make a simple enough program in C#, but it seems to be impossible via usual WinForms means. I need to show something (a string of text, an image) on the screen for very small time interval. Since typical monitors are 60Hz, this interval would be 1 or 2 frames (16,6 or 33,3 ms). I tried doing this with usual WinForms, and it is not possible because, apparently, there is no way to know how many frames were output to the monitor since some point in time. I can only draw on the controls, and monitor output is totally independant. So even if I run the timer, say, for 17 ms, between showing and hiding the image, it still sometimes manages not to draw a single frame of my image on the screen (even though theoretically it should, because 17ms 16,6ms). Moreover, even 20ms seems to slow (even though i should be more than enough). I did some game development as a hobby in the past (Delphi X, XNA) and I know that you usually draw the whole screen by yourself, each frame. Also, I know that there is an option called Vsync in most modern games, that allows you to synchronize your framerate to your monitor's frame rate. So, is it possible? I mean, to actually know how many frames were sent to the monitor with w/e I want to show?

  • Stopping the animation after you let go of a key

    - by Michael Zeuner
    What I have right now is an animation that starts when I press space: if(input.isKeyDown(Input.KEY_SPACE)) player = movingRightSwingingSword; However when I stop clicking space my animation continues. until I move my player, how do I make it so it stops the animation right when you let go of space? A few lines Animation player, movingUp, movingDown, movingLeft, movingRight, movingRightSwingingSword; int[] duration = {200,200}; public void init(GameContainer gc, StateBasedGame sbg) throws SlickException { Image[] attackRight = {new Image("res/buckysRightSword1.png"), new Image("res/buckysRightSword2.png")}; movingRightSwingingSword = new Animation(attackRight, duration, true); } public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException { if(input.isKeyDown(Input.KEY_SPACE)) player = movingRightSwingingSword; } Full Code package javagame; import org.newdawn.slick.*; import org.newdawn.slick.state.*; public class Play extends BasicGameState { Animation player, movingUp, movingDown, movingLeft, movingRight, movingRightSwingingSword; Image worldMap; boolean quit = false; int[] duration = {200,200}; float playerPositionX = 0; float playerPositionY = 0; float shiftX = playerPositionX + 320; float shiftY = playerPositionY + 160; public Play(int state) { } public void init(GameContainer gc, StateBasedGame sbg) throws SlickException { worldMap = new Image("res/world.png"); Image[] walkUp = {new Image("res/buckysBack.png"), new Image("res/buckysBack.png")}; Image[] walkDown = {new Image("res/buckysFront.png"), new Image("res/buckysFront.png")}; Image[] walkLeft = {new Image("res/buckysLeft.png"), new Image("res/buckysLeft.png")}; Image[] walkRight = {new Image("res/buckysRight.png"), new Image("res/buckysRight.png")}; Image[] attackRight = {new Image("res/buckysRightSword1.png"), new Image("res/buckysRightSword2.png")}; movingUp = new Animation(walkUp, duration, false); movingDown = new Animation(walkDown, duration, false); movingLeft = new Animation(walkLeft, duration, false); movingRight = new Animation(walkRight, duration, false); //doesnt work! vvv movingRightSwingingSword = new Animation(attackRight, duration, true); player = movingDown; } public void render(GameContainer gc, StateBasedGame sbg, Graphics g) throws SlickException { worldMap.draw(playerPositionX, playerPositionY); player.draw(shiftX, shiftY); g.drawString("Player X: " + playerPositionX + "\nPlayer Y: " + playerPositionY, 400, 20); if (quit == true) { g.drawString("Resume (R)", 250, 100); g.drawString("MainMenu (M)", 250, 150); g.drawString("Quit Game (Q)", 250, 200); if (quit==false) { g.clear(); } } } public void update(GameContainer gc, StateBasedGame sbg, int delta) throws SlickException { Input input = gc.getInput(); if(input.isKeyDown(Input.KEY_UP)) { player = movingUp; playerPositionY += delta * .1f; if(playerPositionY>162) playerPositionY -= delta * .1f; } if(input.isKeyDown(Input.KEY_DOWN)) { player = movingDown; playerPositionY -= delta * .1f; if(playerPositionY<-600) playerPositionY += delta * .1f; } if(input.isKeyDown(Input.KEY_RIGHT)) { player = movingRight; playerPositionX -= delta * .1f; if(playerPositionX<-840) playerPositionX += delta * .1f; } if(input.isKeyDown(Input.KEY_LEFT)) { player = movingLeft; playerPositionX += delta * .1f; if(playerPositionX>318) playerPositionX -= delta * .1f; } if(input.isKeyDown(Input.KEY_SPACE)) player = movingRightSwingingSword; if(input.isKeyDown(Input.KEY_ESCAPE)) quit = true; if(input.isKeyDown(Input.KEY_R)) if (quit == true) quit = false; if(input.isKeyDown(Input.KEY_M)) if (quit == true) {sbg.enterState(0); quit = false;} if(input.isKeyDown(Input.KEY_Q)) if (quit == true) System.exit(0); } public int getID() { return 1; } }

  • Change ListView background - strage behaviour

    - by Beasly
    Hi again, I have a problem with changing the background of a view in a ListView. What I need: Change the background image of a row onClick() What actually happens: The background gets changed (selected) after pressing e.g. the first entry. But after scrolling down the 8th entry is selected too. Scroll back to the top the first isn't selected anymore. The second entry is selected now. Continue scrolling and it continues jumping... What i'm dong in the Code: I have channels, and onClick() I toggle an attribute of channel boolean selected and then I change the background. I'm doing this only onClick() thats why I don't get why it's actuelly happening on other entries too. One thing I notices is: It seems to be only the "drawing"-part because the item which get selected "by it self" has still the selected value on false I think it seems to have something to do with the reuse of the views in the custom ListAdapters getView(...) Code of onClick() in ListActivity: @Override protected ViewHolder createHolder(View v) { // createHolder will be called only as long, as the ListView is not // filled TextView title = (TextView) v .findViewById(R.id.tv_title_channel_list_adapter); TextView content = (TextView) v .findViewById(R.id.tv_content_channel_list_adapter); ImageView icon = (ImageView) v .findViewById(R.id.icon_channel_list_adapter); if (title == null || content == null || icon == null) { Log.e("ERROR on findViewById", "Couldn't find Title, Content or Icon"); } ViewHolder mvh = new MyViewHolder(title, content, icon); // We make the views become clickable // so, it is not necessary to use the android:clickable attribute in // XML v.setOnClickListener(new ChannelListAdapter.OnClickListener(mvh) { public void onClick(View v, ViewHolder viewHolder) { // we toggle the enabled state and also switch the the // background MyViewHolder mvh = (MyViewHolder) viewHolder; Channel ch = (Channel) mvh.data; ch.setSelected(!ch.getSelected()); // toggle if (ch.getSelected()) { v.setBackgroundResource(R.drawable.row_blue_selected); } else { v.setBackgroundResource(R.drawable.row_blue); } // TESTING Log.d("onClick() Channel", "onClick() Channel: " + ch.getTitle() + " selected: " + ch.getSelected()); } }); return mvh; } Code of getView(...): @Override public View getView(int position, View view, ViewGroup parent) { ViewHolder holder; // When view is not null, we can reuse it directly, there is no need // to reinflate it. // We only inflate a new View when the view supplied by ListView is // null. if (view == null) { view = mInflater.inflate(mViewId, null); // call own implementation holder = createHolder(view); // TEST // we set the holder as tag view.setTag(holder); } else { // get holder back...much faster than inflate holder = (ViewHolder) view.getTag(); } // we must update the object's reference holder.data = getItem(position); // call the own implementation bindHolder(holder); return view; } I really would appreciate any idea how to solve this! :) If more information is needed please tell me. Thanks in advance!

  • Rotating images makes ui slow

    - by 5w4rley
    i'm trying to implement kind of speedometer. i'm getting informations about rounds per minute, boost and load of an engine over bluetooth and i try to display them on the screen witch 3 arrows witch should point in the right direktion. i tried to use a rotate animation evry time i get data(10-100ms) to setup the arrows. but that makes my ui extremly slow. 500ms to react on a buttonclick. Doese someone know how to make it work better? source code: public void setTacho() { //rotate Tachonadel Rpmcurrentdegree=Rpmcurrentdegree+Rpmdegree; Rpmdegree=((rpms-lastrpm)*RPMtoDegree); RpmAnim=new RotateAnimation((float)Rpmcurrentdegree, (float)Rpmdegree, ivNadel.getWidth()/2, ivNadel.getHeight()/2); RpmAnim.setFillEnabled(true); RpmAnim.setFillAfter(true); ivNadel.setAnimation(RpmAnim); RpmAnim.start(); //rotate Boostbalken currentBoostDegree=currentBoostDegree+BoostDegree; BoostDegree=(boost-lastBoost)*BOOSTtoDegree; //rotate Loadbalken currentLoadDegree=currentLoadDegree+LoadDegree; LoadDegree=(load-lastLoad)*LOADtoDegree; BoostAnim=new RotateAnimation((float)-currentBoostDegree, (float)-BoostDegree, ivBoost.getWidth()/2, ivBoost.getHeight()/2); BoostAnim.setFillEnabled(true); BoostAnim.setFillAfter(true); ivBoost.setAnimation(BoostAnim); BoostAnim.start(); LoadAnim=new RotateAnimation((float)currentLoadDegree, (float)LoadDegree, ivLoad.getWidth()/2, ivLoad.getHeight()/2); LoadAnim.setFillEnabled(true); LoadAnim.setFillAfter(true); ivLoad.setAnimation(LoadAnim); LoadAnim.start(); } when i try to make the rotation only if the values have changed then it works only while they are changing but if they aren't the arrows jump back to the zero position. isnt setfillafter to tell the image that it should hold the new position? code: public void setTacho() { //rotate Tachonadel Rpmcurrentdegree=Rpmcurrentdegree+Rpmdegree; Rpmdegree=((rpms-lastrpm)*RPMtoDegree); if(Rpmdegree!=0) { RpmAnim=new RotateAnimation((float)Rpmcurrentdegree, (float)Rpmdegree, ivNadel.getWidth()/2, ivNadel.getHeight()/2); RpmAnim.setFillEnabled(true); RpmAnim.setFillAfter(true); ivNadel.setAnimation(RpmAnim); RpmAnim.start(); } //rotate Boostbalken currentBoostDegree=currentBoostDegree+BoostDegree; BoostDegree=(boost-lastBoost)*BOOSTtoDegree; //rotate Loadbalken currentLoadDegree=currentLoadDegree+LoadDegree; LoadDegree=(load-lastLoad)*LOADtoDegree; if(BoostDegree!=0) { BoostAnim=new RotateAnimation((float)-currentBoostDegree, (float)-BoostDegree, ivBoost.getWidth()/2, ivBoost.getHeight()/2); BoostAnim.setFillEnabled(true); BoostAnim.setFillAfter(true); ivBoost.setAnimation(BoostAnim); BoostAnim.start(); } if(LoadDegree!=0) { LoadAnim=new RotateAnimation((float)currentLoadDegree, (float)LoadDegree, ivLoad.getWidth()/2, ivLoad.getHeight()/2); LoadAnim.setFillEnabled(true); LoadAnim.setFillAfter(true); ivLoad.setAnimation(LoadAnim); LoadAnim.start(); } } i don't get it =( thx 4 help EDIT: part of the bluetooth Thread that calls the callback while (run) { try { bytes = mmInStream.read(buffer); if (connection.btCallback != null) { connection.btCallback.getData(buffer,bytes); } } catch (IOException e) { break; } the callback methode of the bluetooth thread: public void getData(byte[] bytes, int len) { setTacho(); }

  • Ruby on rails: Image downloads with Authentication/Authorization/Time outs

    - by ak1dnar
    Hi Guys, I'm having few doubts on implementing file downloads. I'm creating an app where I use attachment_fu with Amazon s3 to upload files. Things are working pretty well so far on uploading side. Now its the time to start the file downloads. Here is what I need, a logged in user search and browse for Images and they should able to add the files in to a download basket (Let's say its a Download Shopping Cart). Finally the user should be able to download these file(s) from S3 probably as a zipped file. Is there any plugin/gem where I can use for this?

  • Jquery cycle plugin image resizing issue opera

    - by Sam Gregory
    I am using the cycle plugin within Joomla and it works fine on IE6,FF,SAFARI,CHROME however when you view it in OPERA breaking happens. It loads fine but when it brings in the next slide and every consequent slide after that it re-sizes them to what i can only assume to be the browswe window's width and height. here's my javascript <script type="text/javascript"> $('.fullScreen').cycle({ speed: 1000, timeout: 100 }); </script> css <script type="text/css"> .fullScreen { margin-left: 0px; height: 355px; clear: both; width: 475px; z-index: -1; overflow: hidden; } </script> and finally HTML <div class="fullscreen"> <img width="475px" src="images/someimage1.jpg" /> <img width="475px" src="images/someimage2.jpg" /> <img width="475px" src="images/someimage3.jpg" /> </div> hope I'm not the only one having this problem.

  • jQuery to select where no children or first child is not image

    - by hacker
    I'm trying to dynamically style some elements on my pages. So, if I had the following code: <a href="#"> Select Me </a> <a href="#"> <img src="blah.jpg" /> Don't select me </a> <a href="#"> <div>Don't select me either</div> <img src="blah.jpg" /> </a> <a href="#"> <div>You can select me too.</div> </a> I would like it to select the first and fourth tags. From what I could tell, by using: $("a:first-child") Won't select the first tag because it doesn't have any children (just text). The second tag should not get selected so something like: $("a:first-child").not("img) but that leaves out the first item. EDIT: If there is an IMG anywhere in the A element, don't select it.

  • django admin: Add a "remove file" field for Image- or FileFields

    - by w-
    I was hunting around the net for a way to easily allow users to blank out imagefield/filefields they have set in the admin. I found this http://www.djangosnippets.org/snippets/894/ What was really interesting to me here was the code posted in the comment by rfugger remove_the_file = forms.BooleanField(required=False) def save(self, *args, **kwargs): object = super(self.__class__, self).save(*args, **kwargs) if self.cleaned_data.get('remove_the_file'): object.the_file = '' return object When i try to use this in my own form I basically added this to my admin.py which already had a BlahAdmin class BlahModelForm(forms.ModelForm): class Meta: model = Blah remove_img01 = forms.BooleanField(required=False) def save(self, *args, **kwargs): object = super(self.__class__, self).save(*args, **kwargs) if self.cleaned_data.get('remove_img01'): object.img01 = '' return object when i run it I get this error maximum recursion depth exceeded while calling a Python object at this line object = super(self.__class__, self).save(*args, **kwargs) When i think about it for a bit, it seems obvious that it is just infinitely calling itself causing the error. My problem is i can't figure out what is the correct way i should be doing this. Any suggestions? thanks

  • Correct flip/mirror of pixels of an image?

    - by igor
    http://tinypic.com/r/fwubzc/5 That shows what a flip should be and what a mirror should be. Code for both types of mirrors: void mirrorLeftRight() { for (int x = 0; x < width/2; x++) { for (int y = 0; y < height; y++) { int temp = pixelData[x][y]; pixelData[x][y]=pixelData[width-x][y] pixelData[width-x][y]=temp; } } } void mirrorUpDown() { for (int x = 0; x < width; x++) { for (int y = 0; y < height/2; y++) { int temp = pixelData[x][y]; pixelData[x][y]=pixelData[x][height-y] pixelData[x][height-y]=temp; } } } Does this seem right for mirrors? And for flip, just a matter of using width and height w/o dividing by 2?
