http://issues.apache.org/bugzilla/show_bug.cgi?id=37891 Summary: ImageTranscoder always maintains aspect ratio even when both width / height are set Product: Batik Version: 1.6 Platform: Other OS/Version: other Status: NEW Severity: normal Priority: P2 Component: Utilities AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] JavaDoc for KEY_HEIGHT and KEY_WIDTH indicate that the aspect ratio is maintained if one of these values isn't set. This is true except if you set both values, the aspect ratio of the rendered image is still maintained. The buffered image will be created at the values suggested, but the SVG is rendered to fit within the size at the same aspect ratio as the original document. I would expect that it would be rendered to the full extent of the width and height provided unless one of the values wasn't set. This could be supported alternatively using a new key KEY_MAINTAIN_ASPECT ratio that is checked to see if rendering should always respect the original document aspect ratio. i.e. code to calculate AffineTransform: boolean maintainAspectRatio = true; if (hints.containsKey(KEY_MAINTAIN_ASPECT_RATIO)) { maintainAspectRatio = ((Boolean)hints.get(KEY_MAINTAIN_ASPECT_RATIO)).booleanValue(); } if (maintainAspectRatio) { try { Px = ViewBox.getViewTransform(ref, svgRoot, newWidth, newHeight); } catch (BridgeException ex) { throw new TranscoderException(ex); } if (Px.isIdentity() && (newWidth != docWidth || newHeight != docHeight)) { // The document has no viewBox, we need to resize it by hand. // we want to keep the document size ratio float d = Math.max(docWidth, docHeight); float dd = Math.max(newWidth, newHeight); float scale = dd/d; Px = AffineTransform.getScaleInstance(scale, scale); } } else { float xscale = newWidth / docWidth; float yscale = newHeight / docHeight; Px = AffineTransform.getScaleInstance(xscale, yscale); } -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
