  • Uploading an image file with Paperclip (in RoR) causing error.

    - by mtay
    This should be a simple thing to do, but I'm running into a wall and I'm not sure how to debug this response. In my Image model, I have: class Image < ActiveRecord::Base has_attached_file :image, :styles => { :display => "500x500>", :thumbnail => "95x95>"} Then in my Views, my form contains this: -form_for @image, :html => { :multipart => true } do |image| %tr %td.woc_left =label_tag :image, 'photo to upload', :class => 'required' %td.woc_center =image.file_field :image In my Mysql table, I have a column called "image_file_name" (string). However, when I try to upload an image and submit it, I see 2 errors prohibited this from being saved There were problems with the following fields: Image Paperclip::CommandNotFoundError Image Paperclip::CommandNotFoundError What am I doing wrong? Thank you for your help!

  • Page Speed and it&rsquo;s affect on your business

    - by ihaynes
    Originally posted on: http://geekswithblogs.net/ihaynes/archive/2014/05/29/page-speed-and-itrsquos-affect-on-your-business.aspxPage speed was an important issue 10 years ago, when we all had slow modems, but became less so with the advent of fast broadband connections that even seemed to make Ajax unnecessary.  Then along came the mobile internet and we’re back to a world where page speed and asset optimisation are critical again. If you doubt this an article on SitePoint discussing ’Page Speed and Business Metrics’ may change your mind. http://www.sitepoint.com/page-speed-business-metrics/ Here are some of the figures it quotes: Walmart – saw a 2% increase in conversions for every second of improvement in page load time. Put another way, accumulated growth of revenues went up 1% for every 100 milliseconds of load time improvement. Yahoo – for every 400 milliseconds of improvement, the site traffic increased by 9%. The bottom line is that if people have to wait more than a few seconds for a page to fully render, particularly on a mobile device, they’ll probably go elsewhere. Ignore this at your peril.   For two previous posts on the subject see: Page Weight: 10 easy fixes Xat.com Image Optimiser – Useful for RWD/Mobile

  • How to Detect Sprites in a SpriteSheet?

    - by IAE
    I'm currently writing a Sprite Sheet Unpacker such as Alferds Spritesheet Unpacker. Now, before this is sent to gamedev, this isn't necessarily about games. I would like to know how to detect a sprite within a spriitesheet, or more abstactly, a shape inside of an image. Given this sprite sheet: I want to detect and extract all individual sprites. I've followed the algorithm detailed in Alferd's Blog Post which goes like: Determine predominant color and dub it the BackgroundColor Iterate over each pixel and check ColorAtXY == BackgroundColor If false, we've found a sprite. Keep going right until we find a BackgroundColor again, backtrack one, go down and repeat until a BackgroundColor is reached. Create a box from location to ending location. Repeat this until all sprites are boxed up. Combined overlapping boxes (or within a very short distance) The resulting non-overlapping boxes should contain the sprite. This implementation is fine, especially for small sprite sheets. However, I find the performance too poor for larger sprite sheets and I would like to know what algorithms or techniques can be leveraged to increase the finding of sprites. A second implementation I considered, but have not tested yet, is to find the first pixel, then use a backtracking algorithm to find every connected pixel. This should find a contiguous sprite (breaks down if the sprite is something like an explosion where particles are no longer part of the main sprite). The cool thing is that I can immediately remove a detected sprite from the sprite sheet. Any other suggestions?

  • how to retrieve img alt text with jquery or javascript? [on hold]

    - by kate
    Which is the code with which we can retreive alternative text of image: It is a Cataloge with clothes. Dressers, Shirts, Skirts e.t.c. in front page of a site. The featured images of the categories can be changed manually from someone. I did a check and it is asking me to give alt text. I did it to some images with alt="". But to the cataloge I cannot do it. the code is below: {{ 'option_selection.js' | shopify_asset_url | script_tag }} {{ 'api.jquery.js' | shopify_asset_url | script_tag }} {% if template contains 'customers' %} {{ 'shopify_common.js' | shopify_asset_url | script_tag }} {{ 'customer_area.js' | shopify_asset_url | script_tag }} {% endif %} {% if settings.display_slideshow %}{{ 'jquery.slider.js' | asset_url | script_tag }}{% endif %} {% if settings.include_masonry %}{{ 'jquery.masonry.js' | asset_url | script_tag }}{% endif %} {% if settings.enable_product_image_zoom %}{{ 'jquery.zoom.js' | asset_url | script_tag }}{% endif %} {{ 'fancy.js' | asset_url | script_tag }} {{ 'shop.js' | asset_url | script_tag }} Shopify.money_format = '{{ shop.money_format }}'; {% if template contains "product" %} jQuery(document).ready(function($){ {% if product.variants.size 1 or product.options.size 1 %} new Shopify.OptionSelectors("product-select", { product: {{ product | json }}, onVariantSelected: selectCallback }); {% assign found_one_in_stock = false %} {% for variant in product.variants %} {% if variant.available and found_one_in_stock == false %} {% assign found_one_in_stock = true %} {% for option in product.options %} $('#product-select-option-' + {{ forloop.index0 }}).val({{ variant.options[forloop.index0] | json }}).trigger('change'); {% endfor %} {% endif %} {% endfor %} {% endif %} }); $(function() { $( "#tabs" ).tabs(); });

  • How do I mount a .iso or .dmg image as a CD on a Mac so that it's recognised as a CD and not just a volume?

    - by despicable
    I have a knackered super-drive, and need to install software from a CD. However I do have backup images (as .dmg's) of all my install disks. Usually it all works fine, but with two particular installs it tells me to insert the CD into the drive. Is there anyway to fool the system into mounting the .dmg and make it look like a CD? I believe that Toast can do this, so it's possible. I was just hoping to be able to do it without forking out £80 - I could get an external drive for that (just not right this second)

  • jQuery: script remember values between times it is triggered?

    - by Marius
    Hello there, I am writing an ajax script in jQuery. The script gets new or previous page from a php documents that returns HTML. If, located on page 1, I click next, the script IS able to find the next page number (page2), but when I click it AGAIN, the script again has to be able to find the next page number (page3) and at the minute it doesnt. I was wondering how I can save a variable between time a script is triggered, so that I can just + 1 to each time somebody clicks "next", and -1 when somebody clicks "previous". This is my code: $('.buttonNeste').click(function(event){ event.preventDefault(); if (page == null || id == null ) { var page = parseInt($(this).closest('.paginationFullWidth').attr('id')) + 1; var id = $(this).closest('.paginationFullWidth').siblings('.jtextfill').children('h1').attr('id'); } else { var page = page + 1; } var target = $(this); $.post( 'http://www.example.com/controllers/foo.php', { 'page': ( page ), 'id': id }, function(data) { $(target).closest('.paginationFullWidth').siblings('.commentsContainer').html(data); }); }); Thank you for your time. Kind regards, Marius

  • Saving "heavy" figure to PDF in MATLAB - rendering problem

    - by yuk
    I generate a figure in MATLAB with lot amount of points (100000+) and want to save it into a PDF file. With zbuffer or painters renderer I've got very large and slowly opened file (over 4 Mb) - all points are in vector format. Using OpenGL renderer rasterize the figure in PDF, ok for the plot, but not good for text labels. The file size is about 150 Kb. Try this simplified code, for example: x=linspace(1,10,100000); y=sin(x)+randn(size(x)); plot(x,y,'.') set(gcf,'Renderer','zbuffer') print -dpdf -r300 testpdf_zb set(gcf,'Renderer','painters') print -dpdf -r300 testpdf_pa set(gcf,'Renderer','opengl') print -dpdf -r300 testpdf_op The actual figure is much more complex with several axes and different types of plots. Is there a way to rasterize the figure, but keep text labels as vectors? Another problem with OpenGL is that is does not work in terminal mode (-nosplash -nodesktop) under Mac OSX. Looks like OpenGL is not supported. I have to use terminal mode for automation. The MATLAB version I run is 2007b. Mac OSX server 10.4.

  • Scale background image to wrap content of layout

    - by bjg222
    I have a layout that contains some text fields and has a background image that's displayed at the top of my activity. I'd like the background image to scale to wrap the content (don't care about aspect ratio). However, the image is larger than content, so the layout instead wraps the background image. Here's my original code: <RelativeLayout android:layout_width="fill_parent" android:id="@+id/HeaderList" android:layout_gravity="top" android:layout_height="wrap_content" android:background="@drawable/header"> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/NameText" android:text="Jhn Doe" android:textColor="#FFFFFF" android:textSize="30sp" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:paddingLeft="4dp" android:paddingTop="4dp" /> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:textColor="#FFFFFF" android:layout_alignParentLeft="true" android:id="@+id/HoursText" android:text="170 hours" android:textSize="23sp" android:layout_below="@+id/NameText" android:paddingLeft="4dp" /> </RelativeLayout> After searching through some other questions, I found these two: How to wrap content views rather than background drawable? Scale a Drawable or background image? Based on this, I created a FrameLayout w/ an ImageView showing the background. Unfortunately, I still can't get it to work. I want the height of the background image to shrink/expand w/ the size of the text views, but with the FrameLayout, the ImageView fits to the size of it's parent, and I can't find a way to make the parent fit to the size the text view layout. Here's my updated code: <FrameLayout android:layout_width="fill_parent" android:layout_height="wrap_content" > <ImageView android:src="@drawable/header" android:layout_width="fill_parent" android:scaleType="fitXY" android:layout_height="fill_parent" /> <RelativeLayout android:layout_width="fill_parent" android:id="@+id/HeaderList" android:layout_gravity="top" android:layout_height="wrap_content" > <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/NameText" android:text="John Doe" android:textColor="#FFFFFF" android:textSize="30sp" android:layout_alignParentLeft="true" android:layout_alignParentTop="true" android:paddingLeft="4dp" android:paddingTop="4dp" /> <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:textColor="#FFFFFF" android:layout_alignParentLeft="true" android:id="@+id/HoursText" android:text="170 hours" android:textSize="23sp" android:layout_below="@+id/NameText" android:paddingLeft="4dp" /> </RelativeLayout> </FrameLayout> Does anybody have any suggestions for how best to make an image scale to the size of the contents of some layout? I'm not concerned with the aspect ratio of the image, as it won't matter, I just want it to fill the background. Thanks!

  • How to acquire still webcam image

    - by Silv3rSurf
    I need some help deciding what to use to acquire an image from a webcam. I want to acquire a single image. I know you can typically acquire a still image at a higher resolution than a single video frame. Currently, I am using MATLAB's image acquisition toolbox.. which apparently only supports obtaining frames in video mode(so lower resolution). Which other libraries do you recommend? Has anyone else encountered this problem?
