The Image object holds an image in memory to be used for drawing.

Initializers

• LoadImage(filename): Load an image from filename.
• GrabImage(x, y, width, height): Grab the screen contents at (x, y, width, height) and store it in a new Image object.
• GetTileImage()
• Surface.createImage(): Create a new Surface using the picture data in the image.

System images

• GetSystemArrow(): Get the right-pointing arrow image that comes with the Sphere engine.
• GetSystemUpArrow(): Get the up-pointing arrow image that comes with the Sphere engine.
• GetSystemDownArrow(): Get the down-pointing arrow image that comes with the Sphere engine.

Methods

• Image.clone(): returns a copy of an existing image object
• Image.blit(x, y): Draw the image with the top-left corner at (x, y).
• Image.blitMask(x, y, mask): Draw the image at (x, y) with mask as the tinting color.
• Image.rotateBlit(center_x, center_y, angle): Draw the image centered at (center_x, center_y), rotated by angle radians.
• Image.rotateBlitMask(center_x, center_y, angle, mask): rotateBlit + mask.
• Image.zoomBlit(x, y, factor): Draw the image zoomed by factor with the top-left corner at (x, y).
• Image.zoomBlitMask(x, y, factor, mask): zoomBlit + mask.
• Image.transformBlit(x1, y1, x2, y2, x3, y3, x4, y4): Draw the image with top-left (x1, y1), top-right (x2, y2), bottom-right (x3, y3) and bottom-left (x4, y4).
• Image.transformBlitMask(x1, y1, x2, y2, x3, y3, x4, y4, mask): Draw the image stretched to fit 4 coordinates clockwise from the top-left, with a masking color.
• Image.createSurface(): Create a new Surface using the picture data in the image.

Members

• width The width of the image, in pixels.
• height The height of the image, in pixels.

Notes

Operations cannot be performed on an Image object, so if you need to change the image you should use a Surface instead.
