I have a custom list renderer that has a logo for a business in it. It has a label Logo_URLImage that has the placeholder image. In my code I get the data and assign HashMaps to the list model, h.put("Logo_URLImage",imageURL); where imageURL is a string that has the absolute URL to the image.
On Android it seems to always work, but most of the testing has been on iOS devices. What happens is that images are updated as you'd expect the first time or two that you run it. A run later on will show blank images (flash the place holder image and then blank) and once that happens images will never come back.
Any thoughts on what might be causing this?
Check that you defined the LogoName map entry. Check that it is unique per image?
Check that it doesn't include special characters that might cause an issue.

How can I make InDesign render a region of a page, as it would be rendered when exporting the whole file?
I know I can render a PageItem using the exportFile function, but this will ignore any other PageItems sharing the same region.
My current solution is to make a new document the size of the region of interest, with a copy of each PageItem whose coordinates fall into that region. It’s very inelegant, and it seems it cannot be done without the user seeing windows meaningless to them come and go.
Another approach I can think of is to export the whole spread containing the region, then crop the resulting file using something like ImageMagick. But I’d still prefer to be able to render only the region I need, if possible.
You can open the InDesing document without showing its UI as well.
app.open(filepath, false);
and while closing the doc, simple use
doc.close(SaveOptions.NO);
You anyways don't need to save that doc on disk.
This will let you have the document open without showing its UI at all.
I did something like this recently. Here are my steps:
duplicate all spread items and group them
make a frame with a proper size/position
cut and paste the group into this frame
export the frame as PNG
If you need another region on this spread you don't need to repeat all the steps, you can change size and position of the frame and to export it again.
There is a limitation: master page items will be omitted.
I have a weird error with jwplayer.
I configure it from a Angular JS Controller and load it with a simple preview button which loads the jwplayer with the requested conf.
As simple as this.
jwplayer(id).setup(config);
I have a skin and the skin colors (active, inactive, background) configured.
The issue happens when I click the preview button. Sometimes the player loads with the correct colors and sometimes the player loads with the default skin colors.
Every other jwplayer property get loaded correctly. If I change the skin model it will always load that model but will have the same issue with the colors.
I ran a jwplayer(attribute_id).getConfig() to check which conf has been loaded in both cases and they are exactly the same.
So how is it possible the jwplayer has the skin colors loaded but they don't work in some cases?
Skin related conf obtained from the js api:
skin: "seven"
skinColorActive: "#FFFFFF"
skinColorBackground: "#3B0239"
skinColorInactive: "#EE2A7B"
skinUrl: undefined
The player's version I am using is the 7.4.3
UPDATE
I figured out the issue. I have a function to random generate (number and characters) jwplayer id's in case I have a couple of jwplayers in the same page they have different ids.
Every time I generated a new jwplayer it would use a different id. So I noticed the colors weren't working when the jwplayer id was starting with a number.
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be
followed by any number of letters, digits ([0-9]), hyphens ("-"),
underscores ("_"), colons (":"), and periods (".").
So for some reason although the JQuery selector was wrong, just the colors weren't working, the rest of the setup was working fine.
I assume the CSS couldn't work with a wrong id selector and that's why the colors wouldn't show up...
Skin changes are implemented in your CSS file or within <style></style> tags in the header. It looks like your config file is attempting to pull them into the JavaScript player setup. Here are guidelines for designing and implementing your own skin: https://developer.jwplayer.com/jw-player/docs/developer-guide/customization/css-skinning/skins_creating/
Additionally, I would ensure that you're referencing the correct playback states (idle, buffering, playing, paused) as defined in the JavaScript API when you call for the skin change: https://developer.jwplayer.com/jw-player/docs/developer-guide/api/javascript_api_reference/#playback

I'm working on an SSRS template at present which pulls lots of its format information from a database. Part of this format information sets the Background Image of cells.
I'm currently filling the image by setting the Source to External and pulling its value from the database. This works lovely, however It means pulling the image from a network source each time and while a small efficiency hit, I'd like to try and remove that pull if possible by embedding the standard images.
Again this works fine, I can pull either an external image or an embedded image and display on screen. The problem comes when I'd like the option to do either.
I find that I cannot set the image Source from a field, there isn't an option in the GUI.
I've tried going into the code and entering the details there but I get a validation error:
The 'http://scemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition:Source' element is invalid - The value =First(Fields!bodyBackgroundImageSource.Value, "dsTemplate") is invalid according to its datatype String - The Enumeration constraint failed".
Has anyone else come across this and found a solution or know of a workaround? I can continue using only external images, but would prefer to avoid as many external calls as possible.
In our local environment, we tested this scenario and if the expression can return the correct image name, then the image can display properly. You can check if the "First(Fields!bodyBackgroundImageSource.Value, "dsTemplate")" expression return the image name existing under Images folder on Report Data window. And make sure the image source is embedded.
I have a table view controller with a cell that contains an UIImageView. I also have a NSMutableArray that contains the url's. I want the url's to download the images and place them in the correct order. The NSMutableArray also contains some empty Strings and the cell that it corresponds too I want to have my placeholder image from my image assets.
How can I get it to work? I have also populated each cell with a title and summary but cannot workout how images work.
UPDATE
The code used for the image download. Note the photoLabels contains the array of images. Some of the photos are in the incorrect place once the first placeholder image occurs (It is one index late). Why is it doing that. Does anyone know why. I have println(photoLabels) and all the 50 strings are correct (with some just being "")
If anyone can help that would be great.
let imageURL: String = photoLabels.objectAtIndex(indexPath.row) as String
println(imageURL)
if imageURL == "" {
cell.imageContainer.image = UIImage(named: "placeholder")
} else {
cell.imageContainer.setImageWithURL(NSURL(string: imageURL))
}
return cell
Thanks
This seemingly innocent question actually entails a rat's nest of interesting details. These include:
Use lazy loading of the image, loading them just-in-time, rather than trying to download them up front;
Download the images asynchronously;
While downloading the images as needed, cache them (using NSCache, not NSMutableArray) so that if you scroll back to see some images recently downloaded that you don't have to download them again;
But, in response to memory pressure, make sure to empty the RAM-based cache (but still avail yourself of the persistent storage cache);
If user scrolls quickly down to the 100th row in the table example, make sure that the images for the visible cells don't get backlogged behind the requests for the previous 99 images (nb: you should test your app in suboptimal conditions, e.g. a poor 2G or 3G cellular environment, which can be simulated with the network link conditioner); and
You might want a placeholder image to show until the asynchronously retrieved image is downloaded (or retrieved from the cache).
The bottom line is that this takes a non-trivial amount of effort to do properly. As a result, I'd encourage you to use an existing solution, for example the UIImageView categories that are available from SDWebImage or AFNetworking. Both of these two frameworks offer a nice category for UIImageView that allows you to request the image to be downloaded asynchronously (it's sd_setImageWithURL in SDWebImage; it's setImageWithURL in AFNetworking).
I am trying to figure out how to make a hyperlink in a Livecycle Form which points to a URL which will change on different days that the form is rendered. For example on one day I might want the hyperlink to point to:
mywebsite/mypage?option=XXX
and on another day I want it to point to:
mywebsite/mypage?option=YYY
The XXX and YYY can be passed into the form's data pretty easily as XML, but I just don't know how to make it so that the hyperlink is changed to correspond to this.
Any suggestions?
This can be accomplished with JavaScript in LiveCycle Designer. The following script, placed on the Form's docReady event will let you dynamically change the URL of a text object.
form1::docReady - (JavaScript, client)
// If this code is running on the server, you don't want it to run any code
// that might force a relayout, or you could get stuck in an infinite loop
if (xfa.host.name != "XFAPresentationAgent") {
// You would load the URL that you want into this variable, based on
// whatever XML data is being passed into your form
var sURL = "www.stackoverflow.com"; // mywebsite/mypage?option=xxx
// URLs are encoded in XHTML. In order to change the URL, you need
// to create the right XHTML string and push it into the Text object's
// <value> node. This is a super simple XHTML shell for this purpose.
// You could add all sorts of markup to make your hyperlink look pretty
var sRichText = "<body><p>Foo</p></body>";
// Assuming you have a text object called "Text1" on the form, this
// call will push the rich text into the node. Note that this call
// will force a re-layout of the form
this.resolveNode("Text1").value.exData.loadXML(sRichText, false, true);
}
There are a couple of caveats: URLs in Acrobat are only supported in Acrobat 9.0 and later. So if someone using an older version of Acrobat opens your form, the URLs won't work.
Also, as you can see from the "if (xfa.host.name !=...)" line, this code won't run properly if the form is being generated on the server, because forcing a re-layout of a form during docReady can cause problems on certain older versions of the LiveCycle server. If you do need to run this script on the server, you should probably pick a different event then form::docReady.
I a number of complaints from users in WorkSpace that clicking links opened them in the same tab so they lost their WorkSpace form, and there's no option to change that in Designer 11. I think the solution I came up with for that would work for you too.
I made buttons with no border and no background, and in their click event have this line (in Javascript, run at client)
app.launchURL("http:/stackoverflow.com/", true);
It would be easy to add some logic to choose the right URL based on the day and it doesn't cause any form re-rendering.
In some spots where the hyperlink is in line with other text, I leave the text of the link blue and underlined but with no hyperlink, and just place the button (no background, no border, no caption) over it. Does require positioned and not flowed subforms for that to work, so depending on your layout it could get a little clunky.
Wow, just realized I am super late to the party. Well, for anyone using ES4 facing a similar problem . . .
Ended up using a 3rd party component to manipulate the PDF's hyperlinks...wish there was a better solution as this one costs about $1000.
