  • Rmagick, Watermarks, and Image Transparency

    - by Hulihan Applications
    I'm having trouble making an image semi-transparent. I have one image I'd like to set to 50% opacity and position it over another image(using composite operator:OverCompositeOp). Anyone know how an easy way to do such a thing? A little background: I'm trying to make a good watermark to place over images, but I'm not fan of rmagick's built-in watermark() function or the shade-composite method.

  • Fit Lightbox container in window if image is larger

    - by Bobe
    I'm just looking for a simple way to set the max width and height of the Lightbox container and image based on the window size if the image is larger than the current window size. So say the image is 2000x1200 and the window is 1280x1024, then the max-height and max-width of div.lb-outerContainer and img.lb-image should be set to $(window).height() - 286, $(window).width() - 60 and $(window).height() - 306, $(window).width() - 80 respectively. I'm just having a bit of trouble determining where to go about implementing these rules. Do I do it in the lightbox.js file? If so, where? Would it be acceptable to just throw in some script on the page it's used on?

  • Image "moves" when varying heightForRowAtIndexPath in UITableViewCell.

    - by Kalle
    I have a table view with varying height, as defined in the heightForRowAtIndexPath. For some very odd reason, the image is "indented" to the right based on the height; if the height is low enough, the image is stuck to the left side of the cell, but as the height increases, the image for said cell is shifted rightward compared to other rows. The result of this is a very poor looking list, with images floppily laid out in a zig-zag pattern depending on the height of each individual row. The problem is revealed by this simple example: - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return (indexPath.row+1) * 50; } Each cell is set up (simplified) as a "Subtitle" style cell with: // ... cell.textLabel.text = @"foo"; cell.detailTextLabel.text = @"bar"; cell.imageView.backgroundColor = [UIColor redColor]; // for debugging; i have images with transparent bg cell.imageView.image = anImageThatIs55x50pixelsBig; return cell; Any ideas? My head bleeds from the wall-love-affair. Edit: uploaded a screen which displays this. The "image" is just a screenshot of a tiny area of the screen which makes it look a little weird, but you get the picture I'm sure: http://img28.imageshack.us/img28/549/screenshot20100311at172.png

  • How to change default image of derived ToolStripButton?

    - by Special Touch
    It seems like a simple task. Create a C# class that derives from ToolStripButton. The derived ToolStripButton should behave exactly the same as the parent class in the designer and the application, except that the default image should be different. Surprisingly just changing the constructor is not sufficient: public CustomToolStripButton() { base.Image = (Image) new Bitmap(typeof(CustomToolStripButton), "CustomImage.bmp"); } When the ToolStripButton is displayed in the designer, the original default image is shown. There must be a simple solution. What could it be?

  • Obtaining the tropicity of an image on the iPhone

    - by WhiteTiger
    Hello all I was wondering how it's possible to find out if an image in the iPhone photo library is isotropic or anisotropic. Basically how many millimeters each pixel measures in height and in width. In JPG images the information is hardcoded into the data stream so it's possible to do by simply pointing a const char* to the image file, but I'm not sure I can do that with the data the iPhone image returns. Thank you in advance

  • Image improvment methods for OCR Engine

    - by Amir
    Hello every one, We are working on a software that uses OPENOCR engine to do some OCR on given images, given we are using .NET framework , i was wondering if anyone knows about any good possible filters or sharpening methods that can be applied to the image prior to sending it to OCR engine. I have found for example a grayscaled image is much easier for OCR engine to read than a color images. are there any other techniques or image filttering that you guys know of , that can decrease the error margin by OCR engine ? Thanks a million -Amir

  • UITableViewCellStyleDefault image size

    - by Rob Bonner
    Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

  • Novel fitness measure for evolutionary image matching simulation

    - by Nick Johnson
    I'm sure many people have already seen demos of using genetic algorithms to generate an image that matches a sample image. You start off with noise, and gradually it comes to resemble the target image more and more closely, until you have a more-or-less exact duplicate. All of the examples I've seen, however, use a fairly straightforward pixel-by-pixel comparison, resulting in a fairly predictable 'fade in' of the final image. What I'm looking for is something more novel: A fitness measure that comes closer to what we see as 'similar' than the naive approach. I don't have a specific result in mind - I'm just looking for something more 'interesting' than the default. Suggestions?

  • Jquery galleria - make the first image in the gallery appear automatically

    - by Agrajag
    I've added the excellent galleria-plugin to a website I'm working on. However unlike the demo, I've been unable to make the first image display automatically on page-load. Currently, you have to click an image, before one will appear, after that everything works as expected. And yes, I've tried setting the class of the first image to "active", but without that having any effect. Is there anything obvious I'm missing ? There's a live example at: http://kaciekimber.co.za/property/r8453d

  • Silverlight - Image Not Loading from URI at Runtime!?

    - by Sootah
    I've added an image element to my Silverlight app, and while the image pulls right up when in design mode, it doesn't load at all when running the app. Code is: <Image Height="95" HorizontalAlignment="Left" Margin="12,541,0,0" Name="imgBannerAd" Stretch="Fill" VerticalAlignment="Top" Width="828" Source="http://myurl.com/images/theimage.png" /> What's the deal? I'd tried running the file via the local hard drive and localhost, neither has any effect.

  • Retrieving image from database using Ajax

    - by ama
    I'm trying to read image from database with Ajax, but I could not read the xmlhttp.responseText to the img src. The image is saved as binary data in database and also retrieved as binary data. I'm using Ajax in JSP, because I want to give the user the ability to upload images and I will view the last uploaded image, on mouse over action the Ajax will be activated and get the image back, the problem is in reading the img from the response. This is the Ajax function: function ajaxFunction(path) { if (xmlhttp) { var s = path; xmlhttp.open("GET", s, true); xmlhttp.onreadystatechange = handleServerResponse; xmlhttp.send(null); } } function handleServerResponse() { if (xmlhttp.readyState == 4) { var Image = document.getElementById(Image_Element_Name); document.getElementById(Image_Element_Name).src = "data:" + xmlhttp.responseText; } } I also got exception in the server: 10415315 [TP-Processor1] WARN core.MsgContext - Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java:136) at org.apache.jk.common.ChannelSocket.send(ChannelSocket.java:537) at org.apache.jk.common.JkInputStream.endMessage(JkInputStream.java:127) at org.apache.jk.core.MsgContext.action(MsgContext.java:302) at org.apache.coyote.Response.action(Response.java:183) at org.apache.coyote.Response.finish(Response.java:305) at org.apache.catalina.connector.OutputBuffer.close(OutputBuffer.java:281) at org.apache.catalina.connector.Response.finishResponse(Response.java:478) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:154) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:200) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:685) at java.lang.Thread.run(Thread.java:619) 10415316 [TP-Processor1] WARN common.ChannelSocket - processCallbacks status 2

  • FilePageSetupHeader in MS Project VBA project: Display image dynamically

    - by Anne Schuessler
    I want to display an image when printing a page from MS Page using the FilePageSetupHeader. It all works fine if I pass in the parameter for the Text property as a string as such FilePageSetupHeader Alignment:=pjRight, Text:="&P""C:\filepath\image.gif""" However, I'd prefer to be able to pass the filepath to the image to display as a variable. Somehow I can't get it right. So if I try something like the following: vImagePath = """&P""""" & prjFilePath & "\image.gif"""""" FilePageSetupHeader Alignment:=pjRight, Text:=vImagePath it just displays the path as a string. I'm pretty sure it boils down to something simple like escaping the quotes in the correct way, but I've been playing around with it for a while now and I can't seem to get it right. Any idea how this works?
