Details of Update
1. Additional Raster Scale options added.
1.1 Nearest neighbour – This is the simplest form of scaling and is the type implemented in earlier releases of Scan2CAD. Each pixel is scaled by the scale factor. When scaling up, the image may display a measure of blockiness/jaggedness, (an effect often referred to as ‘staircasing’). This scaling method can be used on any type of image.
1.2 Tile 2×2 – This scaling option will ignore any X and Y scale factors previously set. The X and Y scale factors will both be set to 2. Scaling with this method attempts to reduce the previously referenced ‘staircasing’. This scaling method can only be used to scale up by a factor of 2 and can be used on any type of image.
1.3 Bicubic – This scaling option applies bicubic filtering to sample nearby pixels in an effort to ‘guesstimate’ what the missing pixels would look like in a larger image. This results in less ‘staircasing’ but will produce a softer, less sharp, image. This scaling method can only be used on 24bit color images.
1.4 Bilinear – As 1.3 above but applies bilinear filtering. Results will be softer than 1.3. This scaling method can only be used on 24bit color images.
1.5 BSpline – As 1.3 above but applies bspline filtering. Results will be softer than 1.4. This scaling method can only be used on 24bit color images.
Select added options from:-
Raster Effects > Scale… Raster Scale Settings dialog
The above Raster Scale options are also available via the command line using the following new commands:-
ScaleNearest (or Scale)
Each command should be followed by the required XScaleFactor and YScaleFactor values.
Note: The ScaleTile command should always have the XScaleFactor and YScaleFactor values set to 2
2. Quicker interruption of a Command Line session.
Pressing the ‘ESC’ key to interrupt a running command line session has been made more responsive.
3. PDF bug removed.
There was an issue when colorspace contained a ‘separated’ flag – issue resolved.
4. BMP bug removed.
There was an issue when the BMP header record contained a ‘mirror’ flag – issue resolved.
