217<p>DistortImage() distorts an image using various distortion methods, by mapping color lookups of the source image to a new destination image usally of the same size as the source image, unless 'bestfit' is set to true.</p>
218
219<p>If 'bestfit' is enabled, and distortion allows it, the destination image is adjusted to ensure the whole source 'image' will just fit within the final destination image, which will be sized and offset accordingly. Also in many cases the virtual offset of the source image will be taken into account in the mapping.</p>
220
221<p>If the '-verbose' control option has been set print to standard error the equicelent '-fx' formula with coefficients for the function, if practical.</p>
222
223<p>The format of the DistortImage() method is:</p>
224
225<pre class="code">
226 Image *DistortImage(const Image *image,const DistortImageMethod method,
227 const size_t number_arguments,const double *arguments,
228 MagickBooleanType bestfit, ExceptionInfo *exception)
229</pre>
230
231<p>A description of each parameter follows:</p>
232
233<h5>image</h5>
234<p>the image to be distorted.</p>
235
236<h5>method</h5>
237<p>the method of image distortion.</p>
238
239<p>ArcDistortion always ignores source image offset, and always 'bestfit' the destination image with the top left corner offset relative to the polar mapping center.</p>
240
241<p>Affine, Perspective, and Bilinear, do least squares fitting of the distrotion when more than the minimum number of control point pairs are provided.</p>
242
243<p>Perspective, and Bilinear, fall back to a Affine distortion when less than 4 control point pairs are provided. While Affine distortions let you use any number of control point pairs, that is Zero pairs is a No-Op (viewport only) distortion, one pair is a translation and two pairs of control points do a scale-rotate-translate, without any shearing.</p>
244
245<h5>number_arguments</h5>
246<p>the number of arguments given.</p>
247
248<h5>arguments</h5>
249<p>an array of floating point arguments for this method.</p>
250
251<h5>bestfit</h5>
252<p>Attempt to 'bestfit' the size of the resulting image. This also forces the resulting image to be a 'layered' virtual canvas image. Can be overridden using 'distort:viewport' setting.</p>
253
254<h5>exception</h5>
255<p>return any errors or warnings in this structure</p>
256
257<p>Extra Controls from Image meta-data (artifacts)...</p>
258
cristybaacd172011-04-30 23:11:03 +0000[diff] [blame]259<p>o "verbose" Output to stderr alternatives, internal coefficents, and FX equivalents for the distortion operation (if feasible). This forms an extra check of the distortion method, and allows users access to the internal constants IM calculates for the distortion.</p>
cristy6f77f692011-02-15 15:31:39 +0000[diff] [blame]260
261<p>o "distort:viewport" Directly set the output image canvas area and offest to use for the resulting image, rather than use the original images canvas, or a calculated 'bestfit' canvas.</p>
262
263<p>o "distort:scale" Scale the size of the output canvas by this amount to provide a method of Zooming, and for super-sampling the results.</p>
264
265<p>Other settings that can effect results include</p>
266
267<p>o 'interpolate' For source image lookups (scale enlargements)</p>
268
269<p>o 'filter' Set filter to use for area-resampling (scale shrinking). Set to 'point' to turn off and use 'interpolate' lookup instead</p>

275<p>SparseColorImage(), given a set of coordinates, interpolates the colors found at those coordinates, across the whole image, using various methods.</p>
276
277<p>The format of the SparseColorImage() method is:</p>
278
279<pre class="code">
280 Image *SparseColorImage(const Image *image,const ChannelType channel,
281 const SparseColorMethod method,const size_t number_arguments,

284
285<p>A description of each parameter follows:</p>
286
287<h5>image</h5>
288<p>the image to be filled in.</p>
289
290<h5>channel</h5>
291<p>Specify which color values (in RGBKA sequence) are being set. This also determines the number of color_values in above.</p>
292
293<h5>method</h5>
294<p>the method to fill in the gradient between the control points.</p>
295
296<p>The methods used for SparseColor() are often simular to methods used for DistortImage(), and even share the same code for determination of the function coefficents, though with more dimensions (or resulting values).</p>
297
298<h5>number_arguments</h5>
299<p>the number of arguments given.</p>
300
301<h5>arguments</h5>
302<p>array of floating point arguments for this method-- x,y,color_values-- with color_values given as normalized values.</p>
