Yeah, I've fond it surprisingly easy to implement the swft:color-matrix element. This is now all working, translating brightness, contrast, saturation and hue coloe adjustments into an IDE-compatible matrix. However, something's up with my earlier work on filter support in swfmill-ll. It seems to read to much information for two of the filters (though I'm not sure which ones yet), and writes too much information for the color matrix filter. I'll get to the bottom of it though, but not tomorrow - a small matter of a World Cup opener for England. Night all, Steve PS. Dan. Did you get chance to have a look at the float bug test case as mentioned in my original mail? No worries if not - I know you're busy with xinf - but I need that bug fix to be committed before my filter stuff. -- Steve Webster http://dynamicflash.com ___ swfmill mailing list swfmill@osflash.org http://osflash.org/mailman/listinfo/swfmill_osflash.org

Hi Folks, Just to keep you all updated, I now have a working implementation of a ColorMatrix class in C++. All I need to do now (he says, tongue in cheek) is plum this into swfmill-s somehow. I also noticed that the element contains one two many s. I'll look into that soon-ish.

Perfect - thank you very much for these. No wonder I couldn't guess my way to an implementation. It'll take a while to get this implemented.

Re: [swfmill] Filter and blending mode support
Hi All, > > > > > > Actually the IDE exposes the colour matrix filter as brightness, contrast, saturation and hue sliders from -100 to 100. So, what I'm thinking is do away with the matrix and just have: However, I need to work out a way to translate those values into a matrix. So far I've been reverse engineering a couple of IDE-generated examples, but I can't work out how they get from the BCSH values to the matrix. I can tell you that with all the values at 0, we get an identity matrix: 1, 0, 0, 0, 0 0, 1, 0, 0, 0 0, 0, 1, 0, 0 0, 0, 0, 1, 0 Note that there is a final row to this matrix (so it's 5x5) which is always: 0, 0, 0, 0, 1 ...and is NOT stored in the SWF because it never changes. This completes the identity matrix. The product of this matrix and RBGA value for each pixel to which the filter is applied is the resultant value for each component of the rendered pixel. [R'] [1, 0, 0, 0, 0] [R] [G'] [0, 1, 0, 0, 0] [G] [B'] = [0, 0, 1, 0, 0] [B] [A'] [0, 0, 0, 1, 0] [A] [1'] [0, 0, 0, 0, 1] [1] So the RGBA values stay the same. Here are some of the other values I've reverse engineered thus far: B0 C0 S0 H0 1, 0, 0, 0, 0 0, 1, 0, 0, 0 0, 0, 1, 0, 0 0, 0, 0, 1, 0 B100 C0 S0 H0 1, 0, 0, 0, 100 0, 1, 0, 0, 100 0, 0, 1, 0, 100 0, 0, 0, 1, 0 B0 C100 S0 H0 11, 0, 0, 0, -635 0, 11, 0, 0, -635 0, 0, 11, 0, -635 0, 0, 0, 11, 0 B0 C50 S0 H0 2, 0, 0, 0, -63.5 0, 2, 0, 0, -63.5 0, 0, 2, 0, -63.5 0, 0, 0, 1, 0 B0 C-100 S0 H0 0, 0, 0, 0, 63.5 0, 0, 0, 0, 63.5 0, 0, 0, 0, 63.5 0, 0, 0, 1, 0 B0 C-50 S0 H0 0.5, 0, 0, 0, 31.75 0, 0.5, 0, 0, 31.75 0, 0, 0.5, 0, 31.75 0, 0, 0, 1, 0 If there's a standard algorithm for doing this that someone knows (anyone want to contact [EMAIL PROTECTED] - this is right up his street) then please feel free to enlighten me.

Re: [swfmill] Filter and blending mode support
Have just checked the XML spec - and tags can't start with a number as a character, so unfortunately erix's version won't work. Also, just thinking it through - tags which vary their names (i.e. we don't know whether the first child of would be <1> or <2> or <99>, or whether any given element <1> would have children or not) make it harder for the XSL transform and also for creating a validating schema (if you wanted to do so).

Re: [swfmill] Filter and blending mode support
(I'm afraid I don't like erix's use of numbers as tag names - in fact, I'm not convinced it's legal XML...) or possibly just a string of numbers: 1,2,3,4, 4,2,5,4, 1,1,3,9, 9,2,3,1 ... and leave it up to the coder how to format it - but I think this version is too error-prone (very easy to miss off a comma, for example).

Re: [swfmill] Filter and blending mode support
Okay folks, I've drawn up a draft of how filter and blending mode support might look in swfmill-s syntax. http://mirror1.cvsdude.com/trac/osflash/swfmill/attachment/ticket/14/filter.swfml Please have a look and let me know what you think. Oh, and if anyone has any great ideas on how to represent a 4x4 matrix as easy to read/write xml (for the filter) let me know. 'night all, Steve PS. I've yet to check some of the datatypes for existing swfmill-s compatibility. For example, if swfmill-s doesn't currently support 3 digit RGB hex values (#rgb instead of #rrggbb) then this won't be supported in the filter syntax. Having said that, anything here that swfmill-s doesn't currently support might be worthy of its own ticket. -- Steve Webster http://dynamicflash.com ___ swfmill mailing list swfmill@osflash.org http://osflash.org/mailman/listinfo/swfmill_osflash.org
