Functions

allocatePlace void allocatePlace(uint w, uint h): Allocates space for image data.
blit void blit(Image otherImage, Vecf position): Merges two images (no alpha blending).
bytes ubyte[] bytes(): Gives away bytes as data for an image.
bytes void bytes(ubyte[] data): Accepts bytes as data for an image.
copy Image copy(int x, int y, int cWidth, int cHeight): Redraws the part to a new picture.
draw void draw(IRenderer renderer, Vecf position): Undocumented in source. Be warned that the author may not have intended to support it.
drawEx void drawEx(IRenderer renderer, Vecf position, float angle, Vecf center, Vecf size, ubyte alpha, Color!ubyte color): Undocumented in source. Be warned that the author may not have intended to support it.
empty bool empty(): Whether the data has the current image.
fill void fill(Color!ubyte color): Fills the data with color.
freeData void freeData(): Free image data.
getPixel Color!ubyte getPixel(int x, int y): Returns the pixel at the specified location.
load Image load(string path): Loads a surface from a file. Supported formats are described here: https://code.dlang.org/packages/imageformats
resize Image resize(uint newWidth, uint newHeight): Resizes the image.
scale Image scale(float k): Enlarges the image by a factor.
setPixel void setPixel(int x, int y, Color!ubyte color): Sets the pixel to the specified position.
toTexture void toTexture(): Converts an image to a texture (i.e. for rendering an image with hardware acceleration). At the same time, now, when the image is called, the texture itself will be drawn. You can get such a texture and change its parameters from the "texture" property.
toTextureWithoutShape void toTextureWithoutShape(): Converts an image to a texture (i.e. for rendering an image with hardware acceleration). At the same time, now, when the image is called, the texture itself will be drawn. You can get such a texture and change its parameters from the "texture" property.

Properties

dup Image dup [@property getter]: Dynamic copy of the image.
height uint height [@property getter]: Image height.
pixels Color!ubyte[] pixels [@property getter]
Color!ubyte[] pixels [@property setter]: Image dataset.
texture Texture texture [@property getter]: The texture that was generated by the "toTexture" function. Using the field, you can set the shape of the texture and its other parameters.
width uint width [@property getter]: Image width.
