From: speleo3 Date: Tue, 16 Dec 2008 15:52:36 +0000 (+0000) Subject: * remove sp_item_i2root_affine and sp_item_i2r_affine and replace all calls by X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=025db6f90298127a666cd24bcfc2e22fd35ca84d;p=inkscape.git * remove sp_item_i2root_affine and sp_item_i2r_affine and replace all calls by sp_item_i2doc_affine or sp_item_i2d_affine respectively * remove sp_root_bbox, root->c2p was considered in the wrong place there * in sp_item_i2doc_affine do not consider SP_ITEM(object)->transform for root node, because node does not have a transform attribute * fix style scaling for boolean operations (with viewBox) * fix zoom to fit drawing (with viewBox) * fix export area size for "export drawing" (with viewBox) * fix simultaneous movement of clone + original (with viewBox) --- diff --git a/src/dialogs/export.cpp b/src/dialogs/export.cpp index f1a68c999..cce57486d 100644 --- a/src/dialogs/export.cpp +++ b/src/dialogs/export.cpp @@ -1099,7 +1099,7 @@ sp_export_export_clicked (GtkButton */*button*/, GtkObject *base) } Geom::OptRect area;
