  • Can't draw UImage in UIView::drawRect

    - by Joel
    I know this seems like a simple task, which is why I don't understand why I can't get the image to render. When I set up my UIView, I do the following: myUiView.backgroundColor = [UIColor clearColor]; myUiView.opaque = NO; I create and retain the UIImage in the init function of my UIView: image = [[UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"test" ofType:@"png"]] retain]; then my drawRect looks like this: - (void) drawRect:(CGRect) rect { [image drawInRect:self.bounds]; } Ultimately I'll be manipulating that UIImage via bitmap context, and then in drawRect create a CGImage out of the context, and render that, but for now I'm just trying to get it rendering a known image. I've been digging through this site, as well as the documentation. I've gone down the CG path and tried drawing it with CGContextDrawImage by following the numerous examples other people have posted, but that didn't work either. So I've come back to what seems to be the most straightforward way to draw an image, but it isn't working. Any help would be greatly appreciated. Thanks in advance.

  • Adding a Shadow to a NSImageView

    - by Kevin Sylvestre
    Sorry for the seemingly simple question. I have a NSImageView (added in interface builder) and want to add a shadow outline. I tried using the 'Image View Effects' section of the 'Inspector' but this required enabling a core animation layer. If I set it for the 'Content View' I have very strange appearance side effects. If I set it for the 'Image View' the shadow is cropped (sorry, can't resize the image view). Any ideas?

  • Wrong colors when merging images with PHP

    - by OfficeJet
    Hi, I want to get images ID's and creat from files a merged image according to the given ID's. This code is called by ajax and return the image file name (which is the server time to prevent browser caching). code: if (isset($_REQUEST['items'])){ $req_items = $_REQUEST['items']; } else { $req_items = 'a'; } $items = explode(',',$req_items); $bg_img = imagecreatefrompng('bg.png'); for ($i=0; $i<count($items); $i++){ $main_img = $items[$i].'-large.png'; $image = imagecreatefrompng($main_img); $image_tc = imagecreatetruecolor(300, 200); imagecopy($image_tc,$image,0,0,0,0,300,200); $black = imagecolorallocate($image_tc, 0, 0, 0); imagecolortransparent($image_tc, $black); $opacity = 100; $bg_width = 300; $bg_height = 200; $dest_x = 0;//$image_size[0] - $bg_width - $padding; $dest_y = 0;//$image_size[1] - $bg_height - $padding; imagecopymerge($bg_img, $image_tc, $dest_x, $dest_y, 0, 0, $bg_width, $bg_height, $opacity) ; } $file = $_SERVER['REQUEST_TIME'].'.jpg'; imagejpeg($bg_img, $file, 100); echo $file; imagedestroy($bg_img); imagedestroy($image); die(); The images are shown exactly as I want but with wrong colors. I lately added the part with imagecreatetruecolor and imagecolortransparent, and still got wrong results. I also saved the PNG itself on a 24 bit format and also later as 8 bit - not helping. every ideas is very welcomed ! Thanks

  • Interacting with scene cocos2d

    - by cjroebuck
    I'm attempting to make my first cocos2d (for iphone) multiplayer game and having difficulty understanding how to interact with a scene once it is running. The game is a simple turn-based one and so I have a GameController class which co-ordinates the rounds. I also have a GameScene class which is the actual scene that is displayed during a round of the game. The basic interaction I need is for the GameController to be able to pass messages to the GameScene class.. such as StartRound/StopRound etc. The thing that complicates this is that I am loading the GameScene with a LoadingScene class which simply initialises the scene and replaces the current scene with this one, so there is no reference from GameController to GameScene, so passing messages is quite tricky. Does anyone have any ways to get around this, ideally I would still like to use a Loading class as it smooths out the memory hit when replacing scenes.

  • How to enable camera feature in a sencha touch application using phonegap?

    - by Fabre
    I have developed one application in sencha touch2. I want to design a page in such a way that The page has a default image and one button below that. By clicking that button device camera should open(device mainly iPad and iPhone) and after capturing the image lets see it stored in a folder named as "capture" in your device. Then that captured image should replace that default image. I want to use Phonegap compulsorily. I have seen phone gap APIs for camera but I don't get it how to use it exactly. I am using MAC and Xcode for development.

  • C# / XNA - Load objects to the memory - how it works?

    - by carl
    Hello I'm starting with C# and XNA. In the "Update" method of the "Game" class I have this code: t = Texture2D.FromFile( [...] ); //t is a 'Texture2D t;' which loads small image. "Update" method is working like a loop, so this code is called many times in a second. Now, when I run my game, it takes 95MB of RAM and it goes slowly to about 130MB (due to the code I've posted, without this code it remains at 95MB), then goes immediately to about 100MB (garbare colletion?) and again goes slowly to 130MB, then immediately to 100MB and so on. So my first question: Can You explain why (how) it works like that? I've found, that if I change the code to: t.Dispose() t = Texture2D.FromFile( [...] ); it works like that: first it takes 95MB and then goes slowly to about 101MB (due to the code) and remains at this level. I don't understand why it takes this 6MB (101-95)... ? I want to make it works like that: load image, release from memory, load image, release from memory and so on, so the program should always takes 95MB (it takes 95MB when image is loaded only once in previous method). Whats instructions should I use? If it is important, the size of the image is about 10KB. Thank You!

  • Formula for producing a CGRect for a UIScrollView, that displays a UIImage in scaled to fit way

    - by RickiG
    Hi I am loading in images with varying sizes and putting them in UIScrollViews, all the images are larger than the UIScrollView. The user can scroll and zoom as they please, but initially I would like for the image to be centered and scaled so the largest side of the image aligns with the edge of the scrollView, i.e. if the picture is in landscape I would like to size and scale it so that the left and right side goes all the way to the edge of the UIScrollVIew and vice versa I found a formula in a utility function in the Programming guide but it does not quite fit my needs. My approach is to use: CGrect initialPos = ? [self.scrollView zoomToRect:initialPos animated:YES]; I know the size of my scrollView and the size of my image, what I need to figure out is the scale and CGRect to apply to the scrollView to center and size my image. Hope someone can help out:) Thanks

  • datagrid column custom check mark

    - by Berryl
    I want a read only column bound to a boolean that shows a check mark image when true and nothing when false. The problem is the false value; I just want to show whatever the background of the datagrid is, but I don't see how to clear the image source. What should the Value of the image source be to do this? Cheers, Berryl <DataGridTemplateColumn.CellTemplate> <DataTemplate> <Image Name="imgChecked" Source="\Img_Checkmark" /> <DataTemplate.Triggers> <DataTrigger Binding="{Binding IsPrimary}" Value="False"> <Setter TargetName="imgChecked" Property="Source" Value=""/> *** ??? *** </DataTrigger> </DataTemplate.Triggers> </DataTemplate> </DataGridTemplateColumn.CellTemplate>

    I have an application where I can have an image moving towards the eye. When the image enlarged, I would like to have it resized as 635 px where initial size was 220 px. I have the image with starting position as 0 in z axis. I am wanting to calculate the distance from starting position to the resized image. I have already calculate the distance by hand but when I tried to put it on flash the result is not what i wanted. I am sure that the value I calculated was correct. I know it may be hard to understand my problem. Please help.

  • Would anybody mind taking a look at my XML structure?

    - by Bill H
    I am relatively new to this but I was hoping somebody could offer up a good critique of this XML structure I put together. I am not looking for anything in depth but rather if somebody notices anything inherently wrong with the structure (or any tips to make it better) I'd greatly appreciate it. We have a large amount of products that we wholesale out and our customers were looking for a data feed to incorporate our products into their websites. <product modified=""> <id></id> <title></title> <description></description> <upc></upc> <quantity></quantity> <images> <image width="" height=""></image> <image width="" height=""></image> <image width="" height=""></image> </images> <category> <name></name> <subcategory></subcategory> </category> <sale expiration="">yes</sale> <msrp></msrp> <cube></cube> <weight></weight> <pricing> <tier> <pack><pack> <price></price> </tier> <tier> <pack><pack> <price></price> </tier> <tier> <pack><pack> <price></price> </tier> </pricing> </product> We sell in 3 different pack sizes hence the pricing node.

  • Android how to make ImageView with a minWidth have a border?

    - by Kman
    I want to diplay an image so that it takes up a minmum width of the screen and should scale in its aspect ratio (the image width might be smaller or larger than the minimun width) I also want to have a fixed size border around this image. This is my xml section for it: <ImageView android:id="@+id/detailed_view_boxArt" android:layout_width="wrap_content" android:layout_height="wrap_content" android:minWidth="150dp" android:layout_alignParentLeft="true" android:layout_below="@id/detailed_view_heading" android:padding="10dp" android:layout_marginLeft="5dp" android:scaleType="centerInside" android:background="#000"/> This however does not produce what I want...the problem is that it does not scale the image horizontally far enough (ie. the 10px padding that I have seems a lot more on the right and left) How would I produce the result that I want?

  • How do you get the total asset size (or total resource size) in an Android game?

    - by tom_mai78101
    In an Android Java project, there are two folders, asset and res. To me, I usually put some stuffs, like PNG files, sound files, etc. in either one of the two folder. When resources are increasingly becoming more and more in those folders, the time it takes to load them will increase. Therefore, a loading screen is a must in these situation. The total size is to be used in a loading screen, so that I can guess the average time it takes to load each resources, from 0 bytes to its individual resource file size. I only know that by adding all individual sizes in a respective order, I will then obtain the total asset or res folder size, simply by adding them up. So, when it comes to getting the total file size from either folder, how do you obtain their individual resource/object sizes, respectively? Thanks in advance.

  • Load balancing on Ubuntu Server

    - by SabreWolfy
    I have Ubuntu 10.04.4 server (32-bit) installed on a headless quad-core machine with 2GB RAM. I'm running a command-line analysis which is analyzing a large amount of data, but which does not require a large amount of RAM. The tool does not provide any multi-threading, so the CPU load is sitting at 1.00 (or sometimes just a little over). I ran top and pressed 1 to see the load on each of the cores and noticed that "Cpu1" is always running at 100%. I thought that the load would be distributed between the cores, rather than loading one core all the time. I'm sure I've seen this load-balancing behaviour before in Ubuntu or Debian Desktop versions. Why would the Server edition work differently? The analysis will likely take several hours to run, so loading one core at 100% for many hours while the other 3 remain idle is surely not the best approach?

  • JQuery removed background from iframe

    I'm trying to remove the background image on a page that's being loaded via an iframe within a lightbox effect. I have verified that body is the correct element within the iframe that's being selected, but I can't get the background image to go away. Am I missing something obvious? var body = jQuery('#fancybox-frame').contents().find('body'); body.css({ 'background': '', 'background-image': '', 'background-color': '#fff' });

  • Android Service Multiple Thread Design

    - by Gernot
    Hello, A new question about android and services. Currently I'm developing a App that should send images to a server. It should also be possible to send more images parallel. I made a service that creates for every image a new image. The activity can bind to that service and gather information about the progress. I want to show the current status for every image in a notification (and when the user clicks a notification, an activity with the progress for that image should be shown). But I get several problems with that approach. There are errors with binding, the notification pending event starts the activity completly new, so I lose information about currently sending images and so on. Can someone plase tell me, how I could design such a problem in a appropriate way. thx

  • How to Store and Retrieve Images Using MsSQL (Server Management Studio)

    - by Joe Majewski
    I am having difficulties when trying to insert files into an MsSQL database. I'll try to break this down as best as I can: What data type should I be using to store image files (jpeg/png/gif/etc)? Right now my table is using the image data type, but I am curious if varbinary would be a better option. How would I go about inserting the image into the database? Does Microsoft SQL Server Management Studio have any built in functions that allow insertions of files into tables? If so, how is that done? Also, how could this be done through the use of an HTML form with PHP handling the input data and placing it into the table? How would I fetch the image from the table and display it on the page? I understand how to SELECT the cell's contents, but how would I go about translating that into a picture. Would I have to have a header(Content type: image/jpeg)? I have no problem doing any of these things with MySQL, but the MsSQL environment is still new to me, and I am working on a project for my job that requires the use of stored procedures to grab various data. Any and all help is appreciated. Thank you very much for your responses!

  • Fade animation UITableViewCell

    - by Tomas
    Hi everyone, I have a UITableViewController that populates a UITableView with some data that I pull off the net. The data for each cell consists also of an image used as background, which I'm downloading in a separated NSOperation added to a NSOperationQueue with a MaxConcurrentOperationCount set to 4. As long as the image is not downloaded I'm showing a generic placeholder which I would like to replace (fading out/fading in) with the downloaded image once it's being successfully downloaded. I'm using the following code placed inside the cellForRowAtIndexPath of the UITableViewController. [UIView beginAnimations:@"fade" context:nil]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationDuration:3.0]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; cell.placeholderUIImage.alpha = 0.0; cell.backgroundUIImage.alpha = 1.0; [UIView commitAnimations]; This is unfortunately just working randomly for a couple of rows, since for the most the background image is set instantly, as if the animation started on one cell would have been "overwritten" by the next call of beginAnimations.
