A Frame.js question:ããSay I have a frame called "bgframe" and it has three child frames. The childãframes are each partially transparent and stacked on top of each other, soãthat parts of each of the layers are seen in what's rendered in the terminal.ããI have in the past done this exact thing, and it works great on the BBS. ããMy question today: Is there a way in javascript to iterate over the entireãrendered screen (or a flattened, rendered version of bgframe and its children)?ããI can iterate over those individual child frames and getData(), but each frameãis separate, so where a character is transparent, I'm not getting any data fromãthe frame below. ããI can't use getData() on bgframe because it's just an empty holder parentãframe. At least as far as I can tell.ãã--Joshãã////--------------------------------------------------ãBiC -=- http://breakintochat.com -=- bbs wiki and blogãã---ã þ Synchronetã

If MCMLXXIXãis around, he might have some comments. For now I'll suggest:ããI think that we can probably add a method that will return a flattened versionãof each frame's .data array, with the topmost layers taking precedence overãdata from those below. Here's something that you can try:ãã- Get your layers of frames set up as you've describedã- Call .screenshot(system.text_dir + "blah.bin", false) on the parent frameã- Open text/blah.bin in an ANSI editor; column width is same as frame width wasããIf blah.bin has the image that you're expecting (all of the contents of theãframes tht were visible at the time), then that's a good start and we can moveãon from there. I'll make a Frame.dump method that will do what you're lookingãfor.ããIf not ... something else can be done.ãã---ãechickenãelectronic chicken bbs - bbs.electronicchicken.com - 416-273-7230ã þ Synchronet þ electronic chicken bbs - bbs.electronicchicken.comã
