Method Details

getBindCode()

Get the Image's bindcode. This is for texture loading using BGL calls. See, for example, BGL.glBindTexture and glLoad.
Returns:
int

getDepth()

Get the pixel depth of this image.
Returns:
int

getEnd()

Get the Image's end frame. Used for animated textures.
Returns:
int

getFilename()

Get the filename of the image file loaded into this Image object.
Returns:
string

getMaxXY()

Get the x & y size for the image. Image coordinates range from 0 to size-1.
Returns:
[x, y]
           (type=list of 2 ints)

getMinXY()

Get the x & y origin for the image. Image coordinates range from 0 to size-1.
Returns:
[x, y]
           (type=list of 2 ints)

getName()

Get the name of this Image object.
Returns:
string

getPixelF(x, y)

Get the the colors of the current pixel in the form [r,g,b,a]. Returned values are floats normalized to 0.0 - 1.0. Pixel coordinates are in the range from 0 to N-1. See getMaxXY
Parameters:
x - the x coordinate of pixel.
           (type=int)
y - the y coordinate of pixel.
           (type=int)
Returns:
[ r, g, b, a]
           (type=list of 4 floats)

getPixelI(x, y)

Get the the colors of the current pixel in the form [r,g,b,a]. Returned values are ints normalized to 0 - 255. Pixel coordinates are in the range from 0 to N-1. See getMaxXY
Parameters:
x - the x coordinate of pixel.
           (type=int)
y - the y coordinate of pixel.
           (type=int)
Returns:
[ r, g, b, a]
           (type=list of 4 ints)

getSize()

Get the [width, height] dimensions (in pixels) of this image.
Returns:
list of 2 ints

getSpeed()

Get the Image's speed (fps). Used for animated textures.
Returns:
int

getStart()

Get the Image's start frame. Used for animated textures.
Returns:
int

getXRep()

Get the number of repetitions in the x (horizontal) axis for this Image. This is for texture tiling.
Returns:
int

getYRep()

Get the number of repetitions in the y (vertical) axis for this Image. This is for texture tiling.
Returns:
int

glFree()

Delete this image's data from OpenGL texture memory, only (the image itself is not removed from Blender's memory). Internally, glDeleteTextures (see BGL.glDeleteTextures) is used, but this method also updates Blender's Image object so that its bind code is set to 0. See also Image.glLoad, Image.getBindCode.

glLoad()

Load this image's data into OpenGL texture memory, if it is not already loaded (image.bindcode is 0 if it is not loaded yet).
Returns:
the texture's bind code.
           (type=int)

Note: Usually you don't need to call this method. It is only necessary if you want to draw textured objects in the Scripts window and the image's bind code is zero at that moment, otherwise Blender itself can take care of binding / unbinding textures. Calling this method for an image with nonzero bind code simply returns the image's bind code value (see getBindCode).

reload()

Reloads this image from the filesystem. If used within a loop you need to redraw the Window to see the change in the image, e.g. with Window.RedrawAll().
Returns:
None

Warning: if the image file is corrupt or still being written, it will be replaced by a blank image in Blender, but no error will be returned.

save()

Saves the current image.
Returns:
nothing
           (type=none)

setEnd(end)

Set the Image's end frame. Used for animated textures.
Parameters:
end - The new value in [0, 128].
           (type=int)

setFilename(name)

Change the filename of this Image object.
Parameters:
name - The new full filename.
           (type=string)

Warning: use this with caution and note that the filename is truncated if larger than 160 characters.

setName(name)

Set the name of this Image object.
Parameters:
name - The new name.
           (type=string)

setPixelF(x, y, (r, g, b, a))

Set the the colors of the current pixel in the form [r,g,b,a]. Color values must be floats in the range 0.0 - 1.0. Pixel coordinates are in the range from 0 to N-1. See getMaxXY
Parameters:
x
           (type=int)
y
           (type=int)
r
           (type=float)
g
           (type=float)
b
           (type=float)
a
           (type=float)
Returns:
nothing
           (type=none)

setPixelI(x, y, (r, g, b, a))

Set the the colors of the current pixel in the form [r,g,b,a]. Color values must be ints in the range 0 - 255. Pixel coordinates are in the range from 0 to N-1. See getMaxXY
Parameters:
x
           (type=int)
y
           (type=int)
r
           (type=int)
g
           (type=int)
b
           (type=int)
a
           (type=int)
Returns:
nothing
           (type=none)

setSpeed(speed)

Set the Image's speed (fps). Used for animated textures.
Parameters:
speed - The new value in [1, 100].
           (type=int)

setStart(start)

Get the Image's start frame. Used for animated textures.
Parameters:
start - The new value in [0, 128].
           (type=int)

setXRep(xrep)

Texture tiling: set the number of x repetitions for this Image.
Parameters:
xrep - The new value in [1, 16].
           (type=int)

setYRep(yrep)

Texture tiling: set the number of y repetitions for this Image.
Parameters:
yrep - The new value in [1, 16].
           (type=int)
