2 Queries around the same idea: 1: Is there a simple way to visualise an arbitrary size matrix with svg? ie say: vary opacity or hue, as a gradient over another arbitrary size rectangle.
very basic method: fill in a rectangle for each value in the matrix one longwinded method: use radial gradient with one stop 0.24 and another using a 3x3 kernel to give an average value ~0.2575** and a radius calculated from the scale of the matrix (19x19) to the displayed size of the graphic 2: is there a way to input colour or alpha values for an image directly? as suggested here: "To illustrate, suppose you have a input image which is 5 pixels by 5 pixels, whose color values for one of the color channels are as follows:" http://www.w3.org/TR/SVG/filters.html#feConvolveMatrixElement Jonathan **using the value at the second row and second column of the matrix attached: 0.235 0.233 0.241 0.236 0.197 0.160 0.127 0.121 0.117 0.138 0.142 0.135 0.164 0.170 0.182 0.212 0.206 0.185 0.179 0.251 0.240 0.252 0.248 0.215 0.171 0.121 0.132 0.119 0.141 0.148 0.161 0.174 0.200 0.220 0.230 0.196 0.174 0.169 0.266 0.280 0.302 0.351 0.288 0.237 0.159 0.184 0.200 0.214 0.241 0.255 0.254 0.251 0.302 0.335 0.263 0.189 0.157 0.250 0.251 0.355 0.716 0.379 0.285 0.311 0.283 0.302 0.317 0.357 0.400 0.344 0.316 0.381 0.698 0.320 0.196 0.168 0.201 0.196 0.298 0.375 0.343 0.332 0.369 0.382 0.402 0.421 0.486 0.822 0.432 0.352 0.311 0.302 0.222 0.145 0.133 0.174 0.166 0.235 0.275 0.320 0.390 0.490 0.491 0.495 0.491 0.505 0.511 0.385 0.288 0.239 0.200 0.157 0.090 0.088 0.116 0.114 0.172 0.220 0.275 0.418 0.859 0.607 0.587 0.598 0.528 0.462 0.336 0.244 0.193 0.144 0.088 0.050 0.048 0.077 0.097 0.124 0.181 0.262 0.371 0.520 0.555 0.647 0.940 0.600 0.470 0.307 0.207 0.154 0.100 0.037 0.009 0.013 0.058 0.068 0.107 0.150 0.209 0.299 0.409 0.509 0.655 0.940 0.588 0.380 0.278 0.175 0.139 0.086 0.018 -0.006 -0.015 0.044 0.045 0.085 0.124 0.177 0.232 0.308 0.451 0.576 0.940 0.548 0.388 0.245 0.158 0.088 0.037 0.006 -0.033 -0.036 0.046 0.045 0.071 0.107 0.154 0.201 0.260 0.334 0.445 0.499 0.402 0.289 0.188 0.121 0.049 0.004 -0.018 -0.043 -0.046 0.066 0.047 0.071 0.086 0.131 0.176 0.219 0.293 0.348 0.343 0.294 0.217 0.147 0.072 0.029 -0.003 -0.037 -0.063 -0.057 0.080 0.074 0.094 0.106 0.132 0.147 0.194 0.238 0.280 0.302 0.238 0.148 0.084 0.038 0.004 -0.010 -0.048 -0.058 -0.058 0.088 0.106 0.138 0.161 0.175 0.161 0.189 0.225 0.255 0.242 0.185 0.106 0.037 0.012 -0.011 -0.032 -0.060 -0.051 -0.069 0.144 0.156 0.214 0.292 0.247 0.193 0.184 0.232 0.273 0.302 0.169 0.036 0.018 -0.005 -0.032 -0.047 -0.056 -0.061 -0.065 0.173 0.198 0.299 0.657 0.308 0.234 0.202 0.225 0.306 0.638 0.127 -0.160 -0.032 -0.012 -0.030 -0.049 -0.063 -0.068 -0.063 0.172 0.193 0.257 0.341 0.276 0.231 0.207 0.209 0.230 0.257 0.118 -0.015 -0.023 0.057 -0.020 -0.017 -0.045 -0.057 -0.060 0.164 0.173 0.205 0.242 0.215 0.184 0.166 0.170 0.166 0.168 0.110 0.014 0.007 0.003 -0.014 -0.020 -0.029 -0.055 -0.063 0.161 0.172 0.200 0.227 0.204 0.190 0.173 0.156 0.161 0.161 0.109 0.037 0.022 0.004 0.007 -0.010 -0.036 -0.041 -0.053 ------------------------------------ ----- To unsubscribe send a message to: [email protected] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ----Yahoo!
