How to Resize TPicture?
«
on:
February 18, 2020, 05:59:31 pm »
Hello
I'm creating and loading a picture with:
Code: Pascal
[Select]
[+]
[-]
LocalPicture
:
=
TPicture
.
Create
;
LocalPicture
.
LoadFromFile
(
FileName
)
;
The file can be either a jpg or png.
I would like to ask: what is the right way to resize it? Should I use LocalPicture.Bitmap.SetSize(AWidth, AHeight) ?

Stretchdraw? That is the obvious way. Note you would want to apply a dithering to obtain "sharp" images in extreme cases.
But stretchdraw is the way to start...
StretchDraw is a method of canvas.
btw, aside,: more updates?

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

@Thaddy,
I feel so honored in getting a reply from you!
I'll give a try to your solution and post here if it works.
BTW, do you have any public repo with your own code? I presume that I'll find interesting code...
Anyway, I've been working with Tiny ImageNet 200 and Plant Leaf Disease data sets. So, soon, we'll have examples with these data sets.
