Call
pygame.Surface()
pygame object for representing images to create a new image object. The Surface will be cleared to all black. The only required arguments are the sizes. With no additional arguments, the Surface will be created in a format that best matches the display Surface.The pixel format can be controlled by passing the bit depth or an existing Surface. The flags argument is a bitmask of additional features for the surface. You can pass any combination of these flags:
HWSURFACE creates the image in video memory SRCALPHA the pixel format will include a per-pixel alpha
Both flags are only a request, and may not be possible for all displays and formats.
Advance users can combine a set of bitmasks with a depth value. The masks are a set of 4 integers representing which bits in a pixel will represent each color. Normal Surfaces should not require the masks argument.
Surfaces can have many extra attributes like alpha planes, colorkeys, source rectangle clipping. These functions mainly effect how the Surface is blitted to other Surfaces. The blit routines will attempt to use hardware acceleration when possible, otherwise they will use highly optimized software blitting methods.
There are three types of transparency supported in pygame: colorkeys, surface alphas, and pixel alphas. Surface alphas can be mixed with colorkeys, but an image with per pixel alphas cannot use the other modes. Colorkey transparency makes a single color value transparent. Any pixels matching the colorkey will not be drawn. The surface alpha value is a single value that changes the transparency for the entire image. A surface alpha of 255 is opaque, and a value of 0 is completely transparent.
Per pixel alphas are different because they store a transparency value for every pixel. This allows for the most precise transparency effects, but it also the slowest. Per pixel alphas cannot be mixed with surface alpha and colorkeys.
There is support for pixel access for the Surfaces. Pixel access on hardware surfaces is slow and not recommended. Pixels can be accessed using the
get_at()
andset_at()
functions. These methods are fine for simple access, but will be considerably slow when doing of pixel work with them. If you plan on doing a lot of pixel level work, it is recommended to use apygame.PixelArray
pygame object for direct pixel access of surfaces, which gives an array like view of the surface. For involved mathematical manipulations try thepygame.surfarray
pygame module for accessing surface pixel data using array interfaces module (It's quite quick, but requires NumPy.)Any functions that directly access a surface's pixel data will need that surface to be lock()'ed. These functions can
lock()
andunlock()
the surfaces themselves without assistance. But, if a function will be called many times, there will be a lot of overhead for multiple locking and unlocking of the surface. It is best to lock the surface manually before making the function call many times, and then unlocking when you are finished. All functions that need a locked surface will say so in their docs. Remember to leave the Surface locked only while necessary.Surface pixels are stored internally as a single number that has all the colors encoded into it. Use the
map_rgb()
andunmap_rgb()
to convert between individual red, green, and blue values into a packed integer for that Surface.Surfaces can also reference sections of other Surfaces. These are created with the
subsurface()
method. Any change to either Surface will effect the other.Each Surface contains a clipping area. By default the clip area covers the entire Surface. If it is changed, all drawing operations will only effect the smaller area.
-
blit
()¶ - draw one image onto anotherblit(source, dest, area=None, special_flags=0) -> Rect
Draws a source Surface onto this Surface. The draw can be positioned with the dest argument. Dest can either be pair of coordinates representing the upper left corner of the source. A Rect can also be passed as the destination and the topleft corner of the rectangle will be used as the position for the blit. The size of the destination rectangle does not effect the blit.
An optional area rectangle can be passed as well. This represents a smaller portion of the source Surface to draw.

Pixel alphas will be ignored when blitting to an 8 bit Surface.
For a surface with colorkey or blanket alpha, a blit to self may give slightly different colors than a non self-blit.
-
blits
()¶ - draw many images onto anotherblits(blit_sequence=(source, dest), ...), doreturn=1) -> [Rect, ...] or Noneblits((source, dest, area), ...)) -> [Rect, ...]blits((source, dest, area, special_flags), ...)) -> [Rect, ...]
Draws many surfaces onto this Surface. It takes a sequence as input, with each of the elements corresponding to the ones of
blit()
. It needs at minimum a sequence of (source, dest).Parameters: - blit_sequence -- a sequence of surfaces and arguments to blit them,
they correspond to the
blit()
arguments - doreturn -- if
True

-
convert
()¶ - change the pixel format of an imageconvert(Surface=None) -> Surfaceconvert(depth, flags=0) -> Surfaceconvert(masks, flags=0) -> Surface
Creates a new copy of the Surface with the pixel format changed. The new pixel format can be determined from another existing Surface. Otherwise depth, flags, and masks arguments can be used, similar to the
pygame.Surface()
pygame object for representing images call.If no arguments are passed the new Surface will have the same pixel format as the display Surface. This is always the fastest format for blitting. It is a good idea to convert all Surfaces before they are blitted many times.
The converted Surface will have no pixel alphas. They will be stripped if the original had them. See
convert_alpha()
for preserving or creating per-pixel alphas.The new copy will have the same class as the copied surface. This lets as Surface subclass inherit this method without the need to override, unless subclass specific instance attributes also need copying.
-
convert_alpha
()¶ - change the pixel format of an image including per pixel alphasconvert_alpha(Surface) -> Surfaceconvert_alpha() -> Surface
Creates a new copy of the surface with the desired pixel format. The new surface will be in a format suited for quick blitting to the given format with per pixel alpha. If no surface is given, the new surface will be optimized for blitting to the current display.
Unlike the
convert()
method, the pixel format for the new image will not be exactly the same as the requested source, but it will be optimized for fast alpha blitting to the destination.As with
convert()
the returned surface has the same class as the converted surface.
-
copy
()¶ - create a new copy of a Surfacecopy() -> Surface
Makes a duplicate copy of a Surface. The new surface will have the same pixel formats, color palettes, transparency settings, and class as the original. If a Surface subclass also needs to copy any instance specific attributes then it should override
copy()
.
-
fill
()¶ - fill Surface with a solid colorfill(color, rect=None, special_flags=0) -> Rect
Fill the Surface with a solid color. If no rect argument is given the entire Surface will be filled. The rect argument will limit the fill to a specific area. The fill will also be contained by the Surface clip area.
The color argument can be either a
RGB
sequence, aRGBA
sequence or a mapped color index. If usingRGBA
, the Alpha (A part ofRGBA
) is ignored unless the surface uses per pixel alpha (Surface has theSRCALPHA
flag).New in pygame 1.8: Optional

-
scroll
()¶ - Shift the surface image in placescroll(dx=0, dy=0) -> None
Move the image by dx pixels right and dy pixels down. dx and dy may be negative for left and up scrolls respectively. Areas of the surface that are not overwritten retain their original pixel values. Scrolling is contained by the Surface clip area. It is safe to have dx and dy values that exceed the surface size.
New in pygame 1.9.
-
set_colorkey
()¶ - Set the transparent colorkeyset_colorkey(Color, flags=0) -> Noneset_colorkey(None) -> None
Set the current color key for the Surface. When blitting this Surface onto a destination, any pixels that have the same color as the colorkey will be transparent. The color can be an
RGB
color or a mapped color integer. IfNone
is passed, the colorkey will be unset.The colorkey will be ignored if the Surface is formatted to use per pixel alpha values. The colorkey can be mixed with the full Surface alpha value.
The optional flags argument can be set to
pygame.RLEACCEL
to provide better performance on non accelerated displays. AnRLEACCEL
Surface will be slower to modify, but quicker to blit as a source.
-
get_colorkey
()¶ - Get the current transparent colorkeyget_colorkey() -> RGB or None
Return the current colorkey value for the Surface. If the colorkey is not set then
None
is returned.
-
set_alpha
()¶ - set the alpha value for the full Surface imageset_alpha(value, flags=0) -> Noneset_alpha(None) -> None
Set the current alpha value for the Surface. When blitting this Surface onto a destination, the pixels will be drawn slightly transparent. The alpha value is an integer from 0 to 255, 0 is fully transparent and 255 is fully opaque. If
None
is passed for the alpha value, then alpha blending will be disabled, including per-pixel alpha.This value is different than the per pixel Surface alpha. For a surface with per pixel alpha, blanket alpha is ignored and
None
is returned.Changed in pygame 2.0: per-surface alpha can be combined with per-pixel alpha.
The optional flags argument can be set to
pygame.RLEACCEL
to provide better performance on non accelerated displays. AnRLEACCEL
Surface will be slower to modify, but quicker to blit as a source.
-
get_alpha
()¶ - get the current Surface transparency valueget_alpha() -> int_value
Return the current alpha value for the Surface.
-
lock
()¶ - lock the Surface memory for pixel accesslock() -> None
Lock the pixel data of a Surface for access. On accelerated Surfaces, the pixel data may be stored in volatile video memory or nonlinear compressed forms. When a Surface is locked the pixel memory becomes available to access by regular software. Code that reads or writes pixel values will need the Surface to be locked.
Surfaces should not remain locked for more than necessary. A locked Surface can often not be displayed or managed by pygame.
Not all Surfaces require locking. The
mustlock()
method can determine if it is actually required. There is no performance penalty for locking and unlocking a Surface that does not need it.All pygame functions will automatically lock and unlock the Surface data as needed. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock and unlock pair.
It is safe to nest locking and unlocking calls. The surface will only be unlocked after the final lock is released.
-
unlock
()¶ - unlock the Surface memory from pixel accessunlock() -> None
Unlock the Surface pixel data after it has been locked. The unlocked Surface can once again be drawn and managed by pygame. See the
lock()
documentation for more details.All pygame functions will automatically lock and unlock the Surface data as needed. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock and unlock pair.
It is safe to nest locking and unlocking calls. The surface will only be unlocked after the final lock is released.
-
mustlock
()¶ - test if the Surface requires lockingmustlock() -> bool
Returns
True
if the Surface is required to be locked to access pixel data. Usually pure software Surfaces do not require locking. This method is rarely needed, since it is safe and quickest to just lock all Surfaces as needed.All pygame functions will automatically lock and unlock the Surface data as needed. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock and unlock pair.
-
get_locked
()¶ - test if the Surface is current lockedget_locked() -> bool
Returns
True
when the Surface is locked. It doesn't matter how many times the Surface is locked.
-
get_locks
()¶ - Gets the locks for the Surfaceget_locks() -> tuple
Returns the currently existing locks for the Surface.
-
get_at
()¶ - get the color value at a single pixelget_at((x, y)) -> Color
Return a copy of the
RGBA
Color value at the given pixel. If the Surface has no per pixel alpha, then the alpha value will always be 255 (opaque). If the pixel position is outside the area of the Surface anIndexError
exception will be raised.Getting and setting pixels one at a time is generally too slow to be used in a game or realtime situation. It is better to use methods which operate on many pixels at a time like with the blit, fill and draw methods - or by using
pygame.surfarray
pygame module for accessing surface pixel data using array interfaces/pygame.PixelArray
pygame object for direct pixel access of surfaces.This function will temporarily lock and unlock the Surface as needed.
New in pygame 1.9: Returning a Color instead of tuple. Use
tuple(surf.get_at((x,y)))
if you want a tuple, and not a Color. This should only matter if you want to use the color as a key in a dict.
-
set_at
()¶ - set the color value for a single pixelset_at((x, y), Color) -> None
Set the
RGBA
or mapped integer color value for a single pixel. If the Surface does not have per pixel alphas, the alpha value is ignored. Setting pixels outside the Surface area or outside the Surface clipping will have no effect.Getting and setting pixels one at a time is generally too slow to be used in a game or realtime situation.
This function will temporarily lock and unlock the Surface as needed.
-
get_at_mapped
()¶ - get the mapped color value at a single pixelget_at_mapped((x, y)) -> Color
Return the integer value of the given pixel. If the pixel position is outside the area of the Surface an
IndexError
exception will be raised.This method is intended for pygame unit testing. It unlikely has any use in an application.
This function will temporarily lock and unlock the Surface as needed.
New in pygame 1.9.2.
-
get_palette
()¶ - get the color index palette for an 8-bit Surfaceget_palette() -> [RGB, RGB, RGB, ...]
Return a list of up to 256 color elements that represent the indexed colors used in an 8-bit Surface. The returned list is a copy of the palette, and changes will have no effect on the Surface.
Returning a list of
Color(with length 3)
instances instead of tuples.New in pygame 1.9.
-
get_palette_at
()¶ - get the color for a single entry in a paletteget_palette_at(index) -> RGB
Returns the red, green, and blue color values for a single index in a Surface palette. The index should be a value from 0 to 255.

instance instead of a tuple.
-
set_palette
()¶ - set the color palette for an 8-bit Surfaceset_palette([RGB, RGB, RGB, ...]) -> None
Set the full palette for an 8-bit Surface. This will replace the colors in the existing palette. A partial palette can be passed and only the first colors in the original palette will be changed.
This function has no effect on a Surface with more than 8-bits per pixel.
-
set_palette_at
()¶ - set the color for a single index in an 8-bit Surface paletteset_palette_at(index, RGB) -> None
Set the palette value for a single entry in a Surface palette. The index should be a value from 0 to 255.
This function has no effect on a Surface with more than 8-bits per pixel.
-
map_rgb
()¶ - convert a color into a mapped color valuemap_rgb(Color) -> mapped_int
Convert an
RGBA
color into the mapped integer value for this Surface. The returned integer will contain no more bits than the bit depth of the Surface. Mapped color values are not often used inside pygame, but can be passed to most functions that require a Surface and a color.See the Surface object documentation for more information about colors and pixel formats.
-
unmap_rgb
()¶ - convert a mapped integer color value into a Colorunmap_rgb(mapped_int) -> Color
Convert an mapped integer color into the
RGB
color components for this Surface. Mapped color values are not often used inside pygame, but can be passed to most functions that require a Surface and a color.See the Surface object documentation for more information about colors and pixel formats.
-
set_clip
()¶ - set the current clipping area of the Surfaceset_clip(rect) -> Noneset_clip(None) -> None
Each Surface has an active clipping area. This is a rectangle that represents the only pixels on the Surface that can be modified. If
None
is passed for the rectangle the full Surface will be available for changes.The clipping area is always restricted to the area of the Surface itself. If the clip rectangle is too large it will be shrunk to fit inside the Surface.
-
get_clip
()¶ - get the current clipping area of the Surfaceget_clip() -> Rect
Return a rectangle of the current clipping area. The Surface will always return a valid rectangle that will never be outside the bounds of the image. If the Surface has had
None
set for the clipping area, the Surface will return a rectangle with the full area of the Surface.
-
subsurface
()¶ - create a new surface that references its parentsubsurface(Rect) -> Surface
Returns a new Surface that shares its pixels with its new parent. The new Surface is considered a child of the original. Modifications to either Surface pixels will effect each other. Surface information like clipping area and color keys are unique to each Surface.
The new Surface will inherit the palette, color key, and alpha settings from its parent.
It is possible to have any number of subsurfaces and subsubsurfaces on the parent. It is also possible to subsurface the display Surface if the display mode is not hardware accelerated.

mysurf.get_rect(center=(100, 100))
to create a rectangle for the Surface centered at a given position.
-
get_bitsize
()¶ - get the bit depth of the Surface pixel formatget_bitsize() -> int

This function will temporarily lock and unlock the Surface as needed.
New in pygame 1.8.
-
get_view
()¶ - return a buffer view of the Surface's pixels.get_view(<kind>='2') -> BufferProxy
Return an object which exports a surface's internal pixel buffer as a C level array struct, Python level array interface or a C level buffer interface. The pixel buffer is writeable. The new buffer protocol is supported for Python 2.6 and up in CPython. The old buffer protocol is also supported for Python 2.x. The old buffer data is in one segment for kind '0', multi-segment for other buffer view kinds.
The kind argument is the length 1 string '0', '1', '2', '3', 'r', 'g', 'b', or 'a'. The letters are case insensitive; 'A' will work as well. The argument can be either a Unicode or byte (char) string. The default is '2'.
'0' returns a contiguous unstructured bytes view. No surface shape information is given. A
ValueError
is raised if the surface's pixels are discontinuous.'1' returns a (surface-width * surface-height) array of continuous pixels. A
ValueError
is raised if the surface pixels are discontinuous.'2' returns a (surface-width, surface-height) array of raw pixels. The pixels are surface-bytesize-d unsigned integers. The pixel format is surface specific. The 3 byte unsigned integers of 24 bit surfaces are unlikely accepted by anything other than other pygame functions.
'3' returns a (surface-width, surface-height, 3) array of
RGB
color components. Each of the red, green, and blue components are unsigned bytes. Only 24-bit and 32-bit surfaces are supported. The color components must be in eitherRGB
orBGR
order within the pixel.'r' for red, 'g' for green, 'b' for blue, and 'a' for alpha return a (surface-width, surface-height) view of a single color component within a surface: a color plane. Color components are unsigned bytes. Both 24-bit and 32-bit surfaces support 'r', 'g', and 'b'. Only 32-bit surfaces with
SRCALPHA
support 'a'.The surface is locked only when an exposed interface is accessed. For new buffer interface accesses, the surface is unlocked once the last buffer view is released. For array interface and old buffer interface accesses, the surface remains locked until the BufferProxy object is released.
New in pygame 1.9.2.
-
get_buffer
()¶ - acquires a buffer object for the pixels of the Surface.get_buffer() -> BufferProxy
Return a buffer object for the pixels of the Surface. The buffer can be used for direct pixel access and manipulation. Surface pixel data is represented as an unstructured block of memory, with a start address and length in bytes. The data need not be contiguous. Any gaps are included in the length, but otherwise ignored.
This method implicitly locks the Surface. The lock will be released when the returned
pygame.BufferProxy
pygame object to export a surface buffer through an array protocol object is garbage collected.New in pygame 1.8.
