Compare images

[Lucas]

something wrong?

Code:

Copy      Help

str a="$Desktop$\prueba.bmp"
a.getclip(CF_BITMAP)
str b="$Desktop$\prueba3.bmp"
b.getclip(CF_BITMAP)

if(a<>b) mes("<>")

[Gintaras]

getclip does not store the clipboard data to the variable when CF_BITMAP format is specified. It only writes the bitmap to the file. You can then compare files:

...
a.getfile(a)
b.getfile(b)
...

Ok

[Darkblade]

Is it possible to compare the files to get the X and Y coordinates of the first occurrence of a difference is found in the second image?

Quick Macros does not have such function.
Could get all pixels and compare in loop, but in QM it is slow. Could use C or C#, but in any case need some programming.
Or find a library that can do it. For example, look in Freeimage C documentation: https://freeimage.sourceforge.io/documentation.html
