Fortran_stb_image

Fortran bindings for stb_image and stb_image_write.

Usage

program test

implicit none

use stb_image_mod
use stb_image

integer :: data(100,100,3), x, y, n_channels, err

data = 255
data(:, :50, 1)=0
! write to png
err = write_image("image.png", data)
! write to jpg with 80 qulaity
err = write_image("image.jpg", data, 80)

! inquire image data without decoding image
err = stbi_info("image.png", x, y, n_channels)

! load png image
x = 100
y = 100
n_channels = 3
image = stbi_load("image.tga", x, y, n_channels, 0)
! check loading failure reason 
print*,stbi_failure_reason()

end program

See app/main.f90 for further examples.

Building

Currently only supports building via fpm
