When I try to save a bitmap to an image file, it works OK if both dimensions are less than 4096 pixels. But if a dimension of the bitmap is greater than 4096 then the bitmap is scaled in that direction to equal 4096.
Here is an example
set display mode 1024,768,32,1
sync on
create bitmap 1,1024,4096
set current bitmap 1
cls rgb(255,0,0)
box 0,0,512,512
get image 1,0,0,1024,4096,3
save image "testa.bmp",1
create bitmap 2,2048,8192
set current bitmap 2
cls rgb(255,0,0)
box 0,0,1024,1024
get image 2,0,0,2048,8192,3
save image "testb.bmp",2
The reason I am interested in this is that I would like to produce high resolution images to display as posters.
For example, snapmad.com advises that (http://snapmad.com/about.php) a print of size 45 x 30 inches is OK at 6750 x 4500 but looks better at 13500 x 9000.
(Perhaps though this only applies to camera images where pixels are not entirely independent.)
Is there any way I can create images larger than 4096 x 4096?
