Re: FlexPrintJobScaleType doesn't work for me
I did it as you suggested and create a PDF on the server side instead of using FlexPrintJob now. To achieve this I've introduced a new endpoint to my server side API that expects an image and some metadata. The services scale the image, create a PDF and returns an url to the created PDF. Maybe it makes more sense to scale the image at client side... To be able to pass the image within some meta data via JSON I've encoded the image as base64. (This means that the payload increases at approximately 30%, but this no issue here). I've created a gist [1], maybe it is helpful for others. Thanks for the help!

Re: Re: FlexPrintJobScaleType doesn't work for me
Hi Doug, good to know that I'm not alone ;-) >send the doc to a pdf creator on the server That's a good idea. What do you mean with 'doc'? Do you send an image representation of the Flex component to the server? If so, how do you create this?

Re: FlexPrintJobScaleType doesn't work for me
We have tried to use FlexPrintJob in the past with or without printAsBitmap set. But we found the final print usually has odd artefacts included just as you are seeing. Unless you have a fairly simple document and you know it will never be more than one page long, I would suggest these alternatives. ** And of course this is the great beauty of Flex - it's fle-e-ex-ible! Option 1 : Wrap up your document in the simplest DataGrid you can devise and then use PrintDataGrid. This works well but you may need to paginate manually and put the pages in different rows otherwise single lines of text can get split through the middle. Option 2 (which is my current preference) : When user clicks Print, send the doc to a pdf creator on the server and return the url of the saved pdf. On receipt of url, spawn Adobe Reader so that the user can print with the superb print interface in Adobe Reader. At first sight this appears a 'clunky' solution, but users quickly appreciate the sheer power of the Adobe Printer and the output is always perfect no matter what you throw at it.

Thanks Alex, I'll take a look at it soon! >Regarding alpha, I think if the thing you print has alpha < 0, you >actually want to print the parent of that thing. Mhhh... there's a transparent rectangle on top which has an alpha <1. I just would like to print exactly the same that is on the screen. But this transparent rectangle is printed as a black rectangle so the underlying content is hidden [1].

Re: FlexPrintJobScaleType doesn't work for me
In looking at the source for FlexPrintJob, if the thing you are printing isn't the main app, then the currently size of the thing is used to compute how to scale to fill the page, but after that, validateNow() is called. If the thing you print computes to a different size that is too large for the page then it will split the page. So step into it again and watch how the width/height is computed and handled and see if it changes on the validateNow() calls. Regarding alpha, I think if the thing you print has alpha < 0, you actually want to print the parent of that thing.

Re: FlexPrintJobScaleType doesn't work for me
Hi Alex, sorry for the late response, I've overlooked your post. It seems to me that sometimes mails from the list doesn't reach my local inbox for whatever reason. >What are you printing? I am trying to print a s:Group that contains several Spark components including a Timebar component that comes from Ardisialibs as an external vendor. >Debug into addObject and watch the size computation. I found that the print job splits the content into a multiple number of pages if it does not fit the size of the page . I thought the print job was able to scale the content automatically by using e.g. 'FlexPrintJobScaleType.FILL_PAGE' to fit the page? Do I have to scale it by myself before printing? I've one more issue with transparent components. If the alpha of a component is <1 that the print job just outputs a black area. It seems to me that this is a known issue. Is there a workaround for this?
