Some issues I'm having (using Imager 0.60 from the ppd on Win32):
1. If I paste a 3 channel PNG image into a 4 channel image,
the result is not properly rendered (sometimes not rendered at all).
I'm trying to port GD::Tiler to Imager::Tiler, and need to be able
to mix 3 and 4 channel images. I'm also trying to port DBD::Chart to Imager,
and will need the 3 => 4 channel paste for it as well.
2. If I paste a 4 channel image w/ transparent pixels into a
4 channel image with existing content (e.g., a filled box() for
a background color), the pasted image's transparent pixels overwrite
the existing content, i.e., the resulting image has transparent pixels,
rather than the prior image contents. Is there an option to do a blended
Are these known issues, or should I open tickets in rt.cpan.org ?
3. What are the existing charting modules for Imager ? I've thus far
found Imager::Plot, Imager::Graph, and Imager::Chart::Radial.
What does Imager::Plot support, just linegraphs ?
lines and scatter graphs ? The docs seem silent on the subject.
I've got current implementations of line, scatter, and area graphs,
boxcharts, pie charts, barcharts, quadtrees/treemaps, and a simple Gantt
chart in DBD::Chart::Plot which I'm porting over to Imager from GD,
and I'm adding bubble charts and bulletcharts, and maybe gauges.
(see www.presicient.com/dbdchart and www.presicient.com/dbixchart for info)
It might be nice to merge these efforts into a single package (the
rendering engines, not the SQL interface).
4. Is there any plan to create a new PPD for version 0.62 soon ?
