Edge Rasterizer Revision History
v1.23b (3/4/2013)Droplet Placement Optimization
Droplet generation has been optimized by removing unnecessary placement checking.
v1.22 (4/4/2012)Droplet Placement Optimization
Speed of the Edge Rasterizer was greatly improved.
Pitch is no longer expressed in percent values. Both Gbrvu's Edge Rasterizer GUI and the independent GUI have been altered to this effect.
v1.21 (1/5/2012)Image Reversal.
Added image reversal mode with margins.BMP Output.
Added BMP Output on top of the existing TIFF and Gerber.Scale
Added scaling option for output data.
v1.20 (3/8/2011)Round flashes to Droplet.
Added mode for dropping single droplet pads for features smaller than a specified threshold. Both the Gbrvu Edge Rasterizer tool and the independent Edge Rasterizer shell were revised to control this.
v1.19 (4/28/2009)Speed Improvement.
This version runs twice as fast as the previous version.
v1.18 (4/2/2009)Exceptions generated from tiff output.
There were exceptions generated from tiff output of an entire file, 132-233-91 l7p.gbr. This was caused by insufficient precision in unionizing droplets. This has now been fixed.Narrow path.
A change was made to handle paths which are close to
the dot size in width. Extra droplets were appearing under
these conditions. This has now been fixed.
v1.17 (3/4/2009)Staggering Placement of Droplets.
All interior filling is now done with staggering placement of droplets.
v1.16 (2/9/2009)Fixing issue with Filling between Interior and Outer Edge.
The method of interior filling has changed. There is the additional filling to cover the area between the interior and outer edge. However, it may or may not affect the flatness of top side, i.e., the ink density because the amount of ink coverage in outer edge is smaller than the ink coverage of the interior.Higher Density on the Neck
This issue was fixed.Different Superposition Ratio
Additional droplets caused the superposition ratio, e.g., nominal pitch is higher
than 30% and 40%.
This issue was fixed.GBRVU 3.12A Edge Rasterizer Enhancement
Added "Min Void Area" Settings - this allows the user to define a minimum value so voids will be smaller than this value.
v1.15 (12/9/2008)Staggering placement of droplets
Narrow lines have staggering placement of droplets.Edge Rasterizer GUI Changes
Changed "Dot Size" label to "Droplet Dia."
v1.14 (10/7/2008)Improved filling
The edge rasterizer has the latest droplets engine with an improved filling algorithm.Edit Droplet Location
Removal of redundant droplets associated with "patching" of holes.
v1.12 (9/17/2008)Improved filling
The edge rasterizer has the latest droplets engine with an improved filling algorithm (files l1_metal.gbr and l2_er.gbr).Edit Droplet Location
Gbrvu's "Edit Droplet Location" dialog box has a check box to move a droplet ten pixel grids at a time.
v1.11 (9/17/2008)Improved filling
The edge rasterizer has the latest droplets engine with an improved filling algorithm.
v1.10 (8/17/2008)Number of droplets
Minor changes made to reduce the number of droplets at the neck of a trace.
v1.08 (2/1/2008)Filling alogorithm
This image improves the filling alogorithm to better handle the transition area between the edge rasterizer data and the interior fills.
v1.07a (12/12/2007)Drop data
This image fixes the dropped data problem that occurred for the following
v1.07 (10/3/2007)Problems fixed
Problems fixed in this version are:
Added dialog controls displaying the "Notch Depth" and "Pitch Bounds" in
relation to the current raster settings. These controls are updated
for the following events:
|Ink Coverage Simulator||Download Program|
|TIFF2DROPLET Utility||Price List|
