I am trying to make a seamless process for creating engineering part drawings that have interactive balloons that will somehow go to the part you clicked. A part balloon contains a part number, I want the user to be able to click that part number to go to that selected part number drawing.
What I am asking help for is if anyone knows or has any recommendations how to achieve this.
We use Solidworks as our CAD software. Currently we create save a copy of the drawing in Solidworks to PDF and that is then converted to an enlarged PNG programmatically. There are currently no hooks, anchors or tags associated with the PNG. The PNG is displayed on our parts browsing website. Currently you cannot interact with the drawing on the webpage other than zooming in and out.
I can change that process to whatever will work, but it needs to be almost completely automated. Any ideas would be appreciated.
So far I have looked into adding JavaScript to the actual PDF document programmatically, but I do not fully understand the interaction between web based JavaScript and PDF JavaScript. There is not much online either, or else I couldn't find it. I have also looked into adding links to the PDF, but i cannot get it to open in the current iFrame when a user clicks a link on the PDF, where i would normally user target="_self" to mitigate this.
Please let me know if I can clarify something, as there is a lot of information and it would be overwhelming to write on here.

I've tried to ask this question before, but I failed completely there. After useful input, I decided to leave that one, and to try again.
I'm looking to create a web-based application where users can draw images built from a set of pre-defined icons. There is a need to be able to save the final image (encoded jpg/png), and also save a "current setup" that can be re-loaded later for further editing (a "settings" file?).
My question : What would be the best approach for this matter? Flash+AS3? HTML5+JS? Something else?
For better understanding of what I want to create, here are 2 screenshots that illustrate in what direction I'm thinking:

Thanks in advance, and I really hope I've made my question more clear this time.
Since you need advice...
Draw your icons in some art software (even online) and save as transparent PNG's
Look-up HTML5 Drag & drop tutorials that involve "Canvas". You'll want to meaure the positions of objects dragged (mouse position on Canvas) and their order. The drag function could update a JSON String (this hold entries of items, type, position, etc)
Look-up How to save JSON as text file, also how to parse text file as JSON. This becomes the "settings file".
To save images best use PHP language code. PHP must be installed on the server (most have, or is installable or else get a better host). There are tutorials on how to save an image with content from "snapshot of Canvas"
flash is unsupported on IOS and android mobile browsers and google is giving a lower index to websites using it.
I would use javascript with HTML5 canvas with PIXI.JS ,CreateJS or PANDA.JS.
These libraries make it easier to create the canvas elements you need (draggable objects, buttons ) from sprites and adding event listeners to them.
And drawing graphics on the canvas (lines, shapes).
Since you have a lot of sprites you can pack them in a spritesheet with TexturePacker for faster loading ( and PIXI works great with spritesheets).
You can package this web page to android/ios with phonegap,ionic,crosswalk, cocoonjs etc ( i recommend ionic + crosswalk webview it gives great performance)
for saving i would also use a json file to save the setting . You can use PHP to load and save it.
I am making my website and I want to show some images on it in small area, say in a 300x300 <div>.
What I want is that the images can be previewed/enlarged when someone clicks on them, so that the user can have a better and bigger view of the image.
For ex.- when you click a product image on flipkart.com / jabong.com, you can see an enlarge view of the image. In flipkart, it magnifies the image, and in jabong, you can rollover the image(which is kind of a zoom).
I have searched a lot over google for some kind of API for this but I couldn't find anything. So, my question is - 'Is there an API which could do this kind of job? If not, then how is can this be implemented? Especially, what jabong does - rolling over the image'.
If there are no APIs, please guide me on how this can be implemented. I don't want any code for implementation. Just give me some good pointers to follow.
You're probably looking for something like this:
Magnifier.js
If this doesn't fit your needs.. a Google Search will reveal a few suggestions:
jquery-zoom-effect-plugins
I have an application that auto-generates a report page.
I.e. a HTML5 webpage with plots and tables.
In some cases users need to edit mark certain details in the report, so they take screenshots/copy paste content into Microsoft Word or similar and then edit it.
I would like to enable the user to do annotation on top of the report inside the browser. For instance draw a circle on top of a spike in a plot. Or insert an arrow pointing at something important. and adding a comment next to it.
They can then print/save the report to pdf including their annotations.
This should not be too hard to do using canvas for drawing and so on. But I guess there should be some framework/library doing that. I just can't find it.
Do you think this makes sense to do and do you know any libraries that supports that?
I guess you mean something like Annotator.
I'm currently using an application that generates large images for organizational maps, unfortunately the content is quite small due to the volume of data being output. I would like to find a way that allows the user to view segments of the map in an intuitive manner, yet still allow the user to click content inside of the map.
The first thing that came to mind was an image magnifier using something similar to the loupe jQuery plugin. This works great for magnifying the image, but I can't select content once magnified. If anyone has any suggestions for possible solutions to this issue I would greatly appreciate the help.
Thanks!
You might try Etalage: http://frique.me/demos/etalage/ -- if you click on the image, the link works (triggers the javascript alert), almost no other image zoomer seems to do that.
I'm trying to find something that returns the coordinates on a click, so I can ask users to zoom and and find things within a picture, and then I'll have the coordinates to crop the picture to extract the items they've found. But I haven't found a script that does that yet, either.
I'm seeing in another forum if the best way to do this is with Javascript or Ajax but I'm wondering if there is an even easier simpler way. I'm trying to create a web service where users can check which countries they have visited from a list of 175 or so and a World map image would then instantly update with a filled color.
There are other similar services, but I'm envisioning mine to be both updating from checks in checkboxes and by clicking on the target country in the displayed image say with an imagemap. Additionally other solutions display all the visited countries in the same color. I would like different colors for different countries or at least for those countries that touch. Eventually I would like to include a feature that enables the choice of which colors to assign countries.
I found a Sourceforge project called pwmfccd. It's simply an open source image of the world and the coordinates on the PNG image for all the countries. You can use mogrify from ImageMagick and floodfill to fill the countries with color. I have done this successfully, locally with batch files.
My ISP has told me where mogrify is located, basically "/usr/bin/mogrify". I now have a horrendously complicated cgi script which if it worked is set to redraw the world map image with each checkbox. It's here. It also redraws the whole web page with each check. The web page starts here. Of course this is not at all efficient, and I think probably the real way to go is Ajax or Javascript, so that maybe just the image gets changed and redrawn, not the whole web page. Sorry I don't even know the difference between Javascript and Ajax and their relative merits at this point.
I suppose you could make just one part of the image update with each check or click on the image instead of even just the image redrawing, but I have never even heard of a hint at being able to do that for irregularly shaped image elements like countries. So I guess an Image map and sister checkbox entries tied to mogrify events redrawing the user's personal copy of the image with an image refresh would be the only way to go.
So how do you do this with something other than Javascript or Ajax or is that definitely the way to go and if so, how would you do it? Or can you after all cut up a web based image into irregular puzzle shaped piece which you can redraw individually at will.
Thanks in advance for reading and considering answering this post.
Well, it looks like maybe my hosting company only supports using PHP with ImageMagick. At least I know better what to try create. I'm completely new to PHP, but I guess that is alright
