I am trying to load the image picked by the camera into Gl editor but its showing black. Here is example of my code
const t = {uri:"content://media/external/images/media/148757"}; // Local storage file path from the camera <Surface style={{width: 250, height: 250}}> <Node shader={shaders.sharpen} uniforms={{ factor, resolution: [250, 250], t, }} /> </Surface>
shaders Config:
const shaders = Shaders.create({ sharpen: { frag: GLSL` precision highp float; varying vec2 uv; uniform sampler2D t; uniform float factor; uniform vec2 resolution; void main() { float test = factor; vec2 step = 1.0 / resolution; vec3 texA = texture2D( t, uv + vec2(-step.x, -step.y) * 1.5 ).rgb; vec3 texB = texture2D( t, uv + vec2( step.x, -step.y) * 1.5 ).rgb; vec3 texC = texture2D( t, uv + vec2(-step.x, step.y) * 1.5 ).rgb; vec3 texD = texture2D( t, uv + vec2( step.x, step.y) * 1.5 ).rgb; vec3 around = 0.25 * (texA + texB + texC + texD); vec3 center = texture2D( t, uv ).rgb; vec3 col = center + (center - around) * factor; gl_FragColor = vec4(col, 1.0); } ` } });
This doesn't work, but if I change the URL to some website image URL for example
const t = {uri: "https://cdn.pixabay.com/photo/2014/02/27/16/10/flowers-276014__340.jpg"}
It was expected to render the image as it renders for an external URL
But it just shows a black screen
