Hi everyone,
I need to create a large bmp or prt file using
QPainterPath(moveTo??lineTo...).The image size maybe 60000*30000 pixel,and I
know that QImage supports a maximum of 32768x32768 px images (signed short), so
I must separate to draw the path.My development environment is Win7-64bit, 4G
RAM, Qt 4.8.4.
Now,I have some points for drawing path.And I want to draw one part,then write
the buffer to file.
for example:I draw an image that size is 10000*10000.I want to draw it
twice,one time is 5000*10000.
The path has 100 points, the upper part maybe 30 points,the lower part maybe 70
points.If drawing it twice,the path maybe not incomplete or
orderless.Especially I draw the lower part,even if setting an offset is not
effective.
How to separate to draw it?Can I get a perfect path finally?
If Qt can not solve this problem,can I solve it with algorithm of scanline
filling or Third-Party library like CImg?
Thanks in advance.
