From 6bce36b6ede16d28626d40a0b4d60954a35ad48f Mon Sep 17 00:00:00 2001 From: Michael Schwarz Date: Thu, 6 Aug 2015 17:32:53 +0200 Subject: Inkscape export: Fix wrong units in Asymptote export. The generate asymptote file would use the Inkscape document coordinates but Asymptote always uses PostScript points. --- support/inkscape/effect.py | 25 ++++++++++++------------- support/inkscape/inkscape.py | 8 ++++---- 2 files changed, 16 insertions(+), 17 deletions(-) diff --git a/support/inkscape/effect.py b/support/inkscape/effect.py index 5fe0daf..c111926 100644 --- a/support/inkscape/effect.py +++ b/support/inkscape/effect.py @@ -97,19 +97,16 @@ class ExportEffect(inkex.Effect): self._layers_by_inkscape_name = { i.inkscape_name: i for i in self._layers } user_unit = self._get_user_unit() - document_unit = self._get_document_unit() - height = self._measure_to_pixels(self._get_document_height_attr()) - - document_transform = simpletransform.composeTransform( - [[1 / document_unit, 0, 0], [0, 1 / document_unit, 0]], - [[1, 0, 0], [0, -1, height]]) + document_height = self._measure_to_pixels(self._get_document_height_attr()) + document_transform = [[1, 0, 0], [0, -1, document_height]] element_transform = [[user_unit, 0, 0], [0, user_unit, 0]] for node in self.document.getroot().xpath('//svg:path', namespaces = inkex.NSS): self._add_shape(node, document_transform, element_transform) def write_dxf(self, file): + document_unit = self._get_document_unit() layer_indices = { l: i for i, l in enumerate(self._layers) } file.write(pkgutil.get_data(__name__, 'dxf_header.txt')) @@ -120,19 +117,19 @@ class ExportEffect(inkex.Effect): handle = 256 - for layer, points in self._paths: - for (x1, y1), (x2, y2) in zip(points, points[1:]): + for layer, path in self._paths: + for (x1, y1), (x2, y2) in zip(path, path[1:]): write_instruction(0, 'LINE') write_instruction(8, layer.export_name) write_instruction(62, layer_indices.get(layer, 0)) write_instruction(5, '{:x}'.format(handle)) write_instruction(100, 'AcDbEntity') write_instruction(100, 'AcDbLine') - write_instruction(10, repr(x1)) - write_instruction(20, repr(y1)) + write_instruction(10, repr(x1 / document_unit)) + write_instruction(20, repr(y1 / document_unit)) write_instruction(30, 0.0) - write_instruction(11, repr(x2)) - write_instruction(21, repr(y2)) + write_instruction(11, repr(x2 / document_unit)) + write_instruction(21, repr(y2 / document_unit)) write_instruction(31, 0.0) handle += 1 @@ -143,6 +140,8 @@ class ExportEffect(inkex.Effect): def write_line(format, *args): print >> file, format.format(*args) + ';' + # Scales pixels to points. + unit_factor = self._unit_factors['pt'] lines_by_layer_name = collections.defaultdict(list) for layer, path in self._paths: @@ -152,7 +151,7 @@ class ExportEffect(inkex.Effect): write_line('path[] {}', layer_name) for path in paths: - point_strs = ['({}, {})'.format(x, y) for x, y in path] + point_strs = ['({}, {})'.format(x / unit_factor, y / unit_factor) for x, y in path] # Hack.
