I have a circuit drawing built with KolourPaint which when printed is about 1/5 the size at which it was drawn on the screen.
Is there a secret squirrel trick to increase the size of the original by perhaps stretching the canvas or something like that without involving another application?
There's no relation between the size on your screen and the size on your printer. Printers are actually much higher-resolution(hundreds of dots per inch).
Unless it's a vector graphic, stretching it would make it blurry.
I was able to find a means to increase the size of a bmp file.
1) Use convert (Slackware command from ImageMagick) to create a postscript file.
2) Use gv to view the created file.
3) There are several options tp increase the size of the PS file. I used 10x and the image is beautiful with complete color transferance.
4) I have not yet tested converting the PS to bmp after increasing the size but feel it is likely an direct method.
Thnx for info but I think this solves my problem. Admit it requires a second application but it is so direct it works for me.
