Create Image 36000px width

Post by Didaktik »

I want to order printing on wide-format printers.
I have a lot of pictures of which I want to create one. The size of the final image obtained 36,000 pixels wide (1.3 meters).
Purebasic can create 8192px only.

How can I solve this?

I think you have to make the file similar to the way the print machine handles them - chunks at a time.

I don't have a solution to creating images this large but to ouput to 1.3 meters in width, you usually use a lower dpi setting like 150dpi or so.

Yes, printer has a resolution of 720dpi, and as I print Pixelart, I decided to multiple zoom 6 times.
And I was able to fit in 8192x8192. )

...but won't the print quality be poor on a large sheet of paper?

Nice compilation.
MSX is missing :( :wink:

120 dpi isn't that bad for such a large print, especially when it's a color image.

That's not true.

Your limits are set by available memory and a 2GB limit
(at least it was).
Help states "8192x8192" as a minimum.
If you can create an 8192x8192 image you should also
be able to create an image with 16384x4096.
Did you try x and y larger than 8192? I only get an
compiler error when x or y is larger than 32000.
32000x13000 at 32 bit works for me (16 GB mem).
