sdl2-image's Introduction

sdl2-image

Hackage Build Status

Haskell bindings to SDL2_image

Both the raw and the higher level bindings should allow you to use any aspect of the original SDL2_image library. Please report an issue if you encounter a bug or feel that something is missing.

Install
cabal install sdl2-image
Documentation

For documentation, visit Hackage.

The original SDL2_image documentation can also help, as the bindings are close to a direct mapping.

Example

A small example executable is included with the library. It loads and displays a given image. You can find it in the example directory.

cd sdl2-image
cabal run path/to/some/image.type

I uninstalled Stack from my Windows machine to try and build this using this guide. I also installed sdl2-image with:

λ stack exec -- pacman --noconfirm -S mingw-w64-x86_64-SDL2_gfx mingw-w64-x86_64-SDL2_image mingw-w64-x86_64-SDL2_mixer mingw-w64-x86_64-SDL2_ttf

I don't know how often people are using SDL2-image, or if they're just using it on something other than Windows, but without smooth compilations on Windows people aren't going to take gamedev with Haskell seriously, so let me know if there's any data you need me to gather as I've read you don't have access to a Windows machine yourself. I really want this to work as I can't really work on my Haskell game too much until I know there's a way of building it on Windows.

Thanks!

Calling load causes the program to do nothing. (Windows, Stack)

The following program has no output:

module Main where

import SDL.Image

main :: IO ()
main = do
  putStrLn "hello world"

  f <- load "guy.png"
  putStrLn $ seq f "f loaded"

Commenting out the last two lines gives the expected output "hello world".

On Windows with stack, in stack.yaml:

extra-deps:
- git: https://github.com/haskell-game/sdl2-image.git
  commit: 382395c763b473032721c71921b5c9241142178f

load fails while loading PNG images

I get a sdlExceptionError = "Unsupported image format" while trying to open a png file with the load function. It works fine with gif files though.

I am using linux, ghc 7.10.2 and SDL2 2.0.3

Windows 10 build error

Was trying to build a project to experience haskell game programming https://github.com/jxv/dino-rush but it failed when trying building sdl2-image:

  • Stack 1.7.1
  • Windows 10 N 64-bit

It seems to be the same issue as #7 which was fixed with this pull request #8. As an haskell beginner I can probably talk about things that I misunderstood but is Stackage up to date with the latest fix?

Here my build logs:
