ActionScript 3.0 :: Detect Width At Specific Y Value?

Apr 28, 2009

I have a MovieClip that has a bunch of MovieClips inside it. I am trying to figure out how wide the MC is at a specific y value. Not sure if there is an easy way to do this.

For an example.

Code:
OOOOOOOO
O O
O O

[code]....

This is the shape of the MC. It is not solid all the way through, it has MCs strewn about inside this outline. I am trying to figure out how wide it is from, say the second 'O' from the bottom. Left to right. The actual MC.width would be 12 'O's wide. But at that bottom portion, it would be 10 'O's wide. I'm not sure how I can do this.

ActionScript 2.0 :: Can't Detect Screen Width

Oct 13, 2003

The problem that I'm facing is in regards to the width of a sliding menu that I've created. The menu slides based on mouse x position and width of the movie. I would like the menu to fit to the entire screen regardless of the users resolution. I wanted to know if there's a way to detect a users screen width and then adjust the variable for screen width within my actionscript.

ActionScript 3.0 :: Detect Converted Width Of String?

Nov 6, 2009

I'm setting up a menu system powered by an XML feed that will have everything created dynamically (graphics, textFields, etc), and I've started pondering something...Since the menu will essentially be in list form, with each button stacked on top of the other, and since the titles will be passed as strings out of attribs in the XML, I was wondering if there was a way (there has to be) to essentially define a width of the text box, but leave the height open, allowing for multiline = true;, and then to dynamically draw the button graphic based off of either the height of the textField or the number of lines the textField uses.

Will this just be a matter of ordering, in that I won't actually draw the box until the textField has been set up, and the title passed to it? That way, the get height method would return the height of the box with the text in it, and I can adjust accordingly? Or should I try to base it off of the number of characters that will be passed to the box, and just set a limit via modulo or something else to "catch" when it goes to the next line (The problem I see with this is that not all characters are == when it comes to width. "i" < "e" in terms of character width, but they are both just single characters).

I would prefer to set something up that auto adjusts, as this list will be changed in the future, and I have no way of knowing if the titles will be a uniform/won't exceed a certain length. I could try to just "go big" to make room, but then you end up with boxes that look empty, and if I undershoot, I've got to go back to code.

IDE :: Detect Width Of JPG Dynamically Loaded Into Blank Movieclip?

Feb 4, 2009

I am loading jpgs into an MC. I make sure I wait to run and modification to the MC by confirming the image is loaded first.If I comment out the IF statements within the function "RW_pic_modifications()" and I trace the width and height of the MC AFTER each photo is loaded, I successfully trace the correct W and H.

My issue, however is when I DO RUN IT THROUGH the conditions within the "RW_pic_modifications()" function. Then any modifications to the MC W and H seem to compound and apply it to each iteration of the next MCs.I confirmed that my code and logic is correct. I just dont understand why performing a resize to the MC with one jpg loaded into it is not reset to the NEW JPG loaded into it, after the new JPG is loaded.

NOTE - I have an MC that stops on a frame until all the code here is executed. Once complete, then this MC plays to allow the pic to stay on screen for a given amount of time THEN it calls on the RW_Pauser() function.I am way over deadline.

Code:
How_long_to_pause = 4000;
Maximum_Image_Width = 137;[code].....

Flash :: Calculate The X & Y Coords - Width And Height Of Specific Piece Of Text Inside A PDF Document

Oct 28, 2010

On my website, I display uploaded PDF files in a flash player for my users to read. I already use various tools to extract the text and produce a serious of high quality images from the file and the system works well. The last piece of the puzzle is to be able to highlight specific parts of the document to help users with accessibility issues.

However I cannot figure out how to calculate where the specific text is positioned on the page? Notes: The documents uploaded to the system are from 3rd parties, so fonts may be embedded. Meaning that I cannot be sure of the width of specific letters. The text to be highlighted may not be unique, the same text may be repeated How can I calculate the coordinates, height and width of a specific piece of text on a PDF, so that I can then draw a box around it?
