Hi Tilman,
I think its better if i get to know the code more, Is there any issues
related to the shading components I can try. Can you please assign/direct
me to some issues on pdfbox ( related to shading )

Hello Thimal,
Don't start prematurely because there are three students who have
applied. I haven't done any ranking (all three applications are good, so
it will be a tough decision). So please don't work on the coons / tensor
shadings yet, and don't optimize anything.
Of course I can't
Hi Tilman,
I'll look in to the PDF spec related to Function Type thanks for the that.
Thanks for the tips on the proposal
I uploaded my proposal to the melange
here is the url

Hello,
The URL doesn't work except for you, the text appeared in the mentors
list and I can also see it in the dashboard. I will give feedback there.

Hi Tilman,
Thanks for the feedback. What you mean by the function calculations is it
function evaluation method can you please give more information on it.
About the proposal what advise can you give, is there specific way that
pdfbox expect apart form the gsoc format and is there any sample
Hello,
The function is something used mostly by shading types 1, 2 and 3. It
uses as input either the coordinates, or the result of a formula based
on them. Enter FunctionType in the PDF spec.
Re: the proposal, no I don't have a sample. I don't even know how the
google format looks like.
Thanks Tilman
for optimization in speed I think we need to facus on methods which use
again and again like getRaster
for the axial shading part current implementation in the getRaster method
we calculate the x' value for the raster inside the for by for loop
for (int j = 0; j h; j++)
Hello,
Yes this is an interesting idea. It would save the recalculation of
y1y0 * (y + j - coords[1]) everytime. (Unless the java compiler
detects this already)
But don't expect too much from it - I believe more time is lost in
function calculation (at least for types 1, 2 and 3 where
Thanks Tilman for the feedback

Hi,
I checked the code related to the shading and studied the pdf spec related
to the type 6. As I see it is going same as the type 4
From what I feel this is need to be done correct me if I'm wrong
first need to get the 12 control points and colors related to each unit
from stream
create the 4

yeah I'm using trunk code(2.0) and I wanted to render the image got it,
thanks. I'm currently studying the 1 to 5 shading implementations and the
pdf spec related to 6 and 7 type shading and i'll buzz you if i got issue.
Once again thanks for quick reply

Hi,
I'm Thimal Kempitiya, third year computer science and engineering
undergraduate at university of moratuwa. I'm interested in the project idea
implement shading with Coons and tensor-product patch meshes. I have the
basic knowledge about the cubic Bézier curves, , bilinear interpolation,
and
You’ll need to use the latest 2.0.0 snapshot jar, which is the unstable version
from trunk
and the place where new development occurs.
