Saving an Inform picturebox. - James D Jarvis - 05-07-2025
This involves using Inform.
I've figured out how to load images generated within the program into picture boxes and edit them but I haven't figured out how to save a picturebox as an image file.
It is possible to have all graphics commands write to a buffer image that is loaded into a picturebox when needed throughout execution of the program, and save that to a file when desired. But that defeats some of the purpose of using Inform.
Any ideas?

Doesn't inForm have an Image property for the Picture Box Control which is a handle you can use with the newish _SaveImage routine?

you can load an image file into a picturebox with a filename as per doumentation
Code: (Select All)
LoadImage Control(PictureBox), ImageFile$
or you can also do this with BeginDraw and EndDraw
Code: (Select All)
limage& = _LoadImage(Imagefile$)
BeginDraw PictureBox1
_PutImage (0, 0), limage&
EndDraw PictureBox1
but I haven't figure out how to save out a picturebox itself.
my problem is while this would add a circle to the picturebox
Code: (Select All)
BeginDraw PictureBox1
circle(30,30),12,_rgb32(100,100,200)
EndDraw PictureBox1
I have no clue how to save that out as an image file from the picturebox. If I could find an image handle in the inform code I could do it but I just haven't figured it out. (or if it has any for the picturebox itself).

I would think the piture box keeps an image handle property for the current image being displayed after mods to original. How else would refresh work?

Using "BeginDraw foo" sets foo as the current destination image. You could then simply use "_SAVEIMAGE fileName$" to write out the current destination image to disk.
