Is posible create a png surface from a png buffer read from a zip file?

thanks for your
​s​
answer

. The Png_data already contains png data. I 'm
looking for a
​simple ​
function
​ ​
like
​:​


sf:=cairo_image_surface_create_from_png_buffer(PNG_data);​

​I managed to load the buffer​ with my own code. Something like this.

dim as integer bytes
dim f as file
dim PNG_data as byte ptr

PNG_data = allocate(100000)

open "mypng.png", #f
read #f, PNG_data,bytes
sf:=cairo_image_surface_create_from_png_buffer(PNG_data,bytes)
close #f
​
