is an RGB color distance.

describes the engine algorithm that should be used to interpret the pixels in the region.

The available transforms are:

Type Description
N None - This is used for those regions that do not need a transform as their only purpose is to describe a rectangle for use by the scraper engine. An example is button location (i0button - i9button) which informs the Autoplayer engine of the allowed rectangle for mouse clicks.
C Color - This is a calculation of the average RGB color for the entire region. Used in conjunction with the radius, the engine will determine if the contents of the region, as seen during game play, match the color/radius as specified in the Table Map. The color value in the region record defines the center of a cube, and the radius defines the dimensions of that cube. This cube is then mapped to an RGB color space, and if the average color of the region falls within this cube, then a match is reported. A negative radius can also be specified, in which case if the average color of the region falls outside of the cube, then a match is reported.
I Image - This transform does two things. It first searches the Image records in the Table Map for a pixel-by-pixel match, and returns the value of that Image record if a match is found. If no pixel-by-pixel match is found, the transform then searches for the closest match, based on this perceptual difference algorithm: http://pdiff.sourceforge.net/ There is an internal hard-coded limit, which prevents Image records from matching the region if 65% or more of available pixels of that region do not match. If this limit did not exist, then clearly non-matching regions could return all sorts of junk. This exact-match-to-pdiff failover is automatic, and requires no additional work from the Table Map creator other than to set the transform to "I" and to collect the images. This is a powerful transform, but be aware that this power comes at the cost of CPU cycles.
T Text - This is an OCR (http://en.wikipedia.org/wiki/Optical_character_recognition) algorithm for the purpose of converting screen pixels to ASCII text. The color cube specifications (as in the C transform) are used to separate the foreground from the background pixels. A lookup is then performed against the Font records in the Table Map on a character by character basis to produce a resultant text string.
Hn Hash n - This transform reduces the contents of the rectangle to a 32-bit value. OpenHoldem and OpenScrape use only a single, well respected hash algorithm that is open for public review. Because of the selection of this algorithm, we have not yet seen a hash collision (that did not have an unrelated root cause, like record duplication). That is not to say that a hash collision is not impossible, however the mapping of 52 card images (for example) into a 32-bit address space makes this highly unlikely. If a collision ever occurs, there is the option to use hash types other than Type 0. Types 0-3 all use different hash seeds with the same algorithm, and thus if a collision is seen, one could simply change the hash type for that region. The Type 0 hash algorithm uses all pixels in a region to calculate a hash. To use specific pixels in the region, use Types 1-3. Types 1-3 default to using all pixels in a region as well, but if Hash Point records are present in the Table Map and of a matching type, the engine will use those specific points for calculation of the hash. Once a region is hashed, the resultant 32-bit hash value is then looked up in the h$ records in the Table Map. If a match is found, the name of the h$ record is returned and acted on appropriately (i.e. common card 1 is Queen-Hearts, Fold button is present, Player 2 is seated, etc.)


Valid region records and their descriptions:

Record Description
c0cardface0 - c0cardface4 Common cards 0-4; represents the entire card, the best transformation is probably hash. Typically either c0cardfaceX is used, or c0cardfaceXrank / c0cardfaceXsuit, but not both. Valid results are a case-insensitive, two character string. The first character is the rank and should be one of: “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “t”, “j”, “q”, “k”, or “a”. The second character is the suit and should be one of: “c”, “d”, “h” or “s”.
c0cardface0rank - c0cardface4rank Rank of common cards 0-4; the best transformation is probably text. Typically either c0cardfaceX is used, or c0cardfaceXrank / c0cardfaceXsuit, but not both. Valid results are case-insensitive, and are one of “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “10”, “t”, “j”, “q”, “k”, or “a”.
c0cardface0suit - c0cardface4suit Suit of common cards 0-4; the best transformation is probably text. Typically either c0cardfaceX is used, or c0cardfaceXrank / c0cardfaceXsuit, but not both. Valid results are case-insensitive, and are one of “c”, “d”, “h” or “s”.
c0handnumber, c0handnumber1 - c0handnumber9 Ten regions to specify where the game state engine should find the current handnumber. The first region found with valid numeric information will be used and the remainder skipped. c0handnumber is searched first, then c0handnumber1 to c0handnumber9 in that order.
c0istournament Used to identify if this table is a tournament game. Any transform can be used equally well with this region. If the result from this region’s transform is anything besides blank (empty string) then this region is considered to represent a tournament game.
c0smallblind Identifies the region on the poker table where the small blind can be found. Title text parsing is much easier to implement if that option is available, otherwise a text transformation can be used with this region to identify the small blind.
c0bigblind Identifies the region on the poker table where the big blind can be found. Title text parsing is much easier to implement if that option is available, otherwise a text transformation can be used with this region to identify the big blind.
c0bigbet Identifies the region on the poker table where the big bet can be found. Title text parsing is much easier to implement if that option is available, otherwise a text transformation can be used with this region to identify the big bet.
c0ante Identifies the region on the poker table where the ante can be found. Title text parsing is much easier to implement if that option is available, otherwise a text transformation can be used with this region to identify the ante.
c0pot0 - c0pot4 The value of the main pot should be identified by c0pot0 using a text transform. c0pot1 to c0pot4 can be used to identify side pots if required.
c0potNchipXY See chip scraping instructions for p0chipXY - p9chipXY below. The difference is that the "N" refers to the different pots - N=0 is the main pot, N=1-4 are side pots.
c0limits, c0limits0 - c0limits9 Identifies the region on the casino table where the limit information can be found; this region is used in conjunction with the Symbol records c0limits and c0limits0-c0limit9 text parse strings. This region should really only be used if title text parsing is not an option.
i0button - i9button Specifies the rectangular area in which the Autoplayer can click the mouse for each button 0-9.
i0label - i9label Specifies the action that should be associated with buttons 0-9. By default, and if not overridden here, button 0 will be interpreted as the fold button, 1 as the call button, 2 as the raise button and 3 as the allin button. The return value from the transformation of this region (hash or text) will determine how the scraper engine interprets the button. All values are changed to lowercase and have spaces and '-' removed. Only the leftmost characters will be tested "allin", "a11in", "allln", "a111n", "aiiin" : button is seen as the allin button "raise", "ra1se", "ralse", "bet" : button is seen as the raise button "call", "caii", "ca11" : button is seen as the call button "check" : button is seen as the check button "fold", "fo1d", "foid" : button is seen as the fold button "autopost", "aut0p0st" : button is seen as the autopost button "sitin", "s1t1n" : button is seen as the sitin button "sitout", "s1tout", "sit0ut", "s1t0ut" : button is seen as the sitout button "leave" : button is seen as the leave button "prefold" : button is seen as the prefold button Examples: "All-In" will be recognized as allin; "Auto-post blinds" will be recognized as autopost
i0labelY - i9labelY Where Y = 0 - 9. As an adjunct to the iXlabel regions, the iXlabelY region definitions allow the specification of an alternative location with alternate properties, such as color, for any button. The specification of these regions is exactly as that of the iXlabel regions with an addition of a numeric (0 - 9) suffix. The iXlabel regions are searched first, then the iXlabelY regions. The first region that resolves to a text value will stop any subsequent evaluations.
i0state - i9state Specifies whether the button0 - button9 is live and available to be clicked. The best transformation is hash or color. If the leftmost characters of the result from this region’s transform are either “true”, "on", "yes", "checked" or "lit" then the button will be seen as available to be clicked. If any other result is returned, such as "false", then the button will be seen as not available to be clicked. Results are case-insensitive.
i3edit Specifies the rectangular region that can be used for entering a SWAG bet.
i86button, i860button - i869button Similar to the i0button - i9button regions, however these regions are intended to be used to combat spam/popups that could occlude the poker window. If the corresponding state region returns true, the Autoplayer will try to click in this region to dismiss the spam/popup.
i86state, i860state - i869state The corresponding state regions for the i86button, i860button - i869button regions above. The best transformation is hash or color. If the leftmost characters of the result from this region’s transform are either “true”, "on", "yes", "checked" or "lit" then the button will be seen as available to be clicked. If any other result is returned, such as "false", then the button will be seen as not available to be clicked. Results are case-insensitive.
p0active - p9active Used to determine if a player is active (sitting in) or not (sitting out). Any transform can be used equally well with this region. If the leftmost characters of the result from this region’s transform are either “true” or “active”, then the region is considered to be active. If any other result is returned, such as "false", "inactive", "out" or "away", then the chair is not considered to be active. Results are case-insensitive.
p0balance - p9balance Used to identify a player's balance. It only makes sense to use a text transform for these regions.
p0bet - p9bet Used to identify a player's bet. It only makes sense to use a text transform for these regions.
p0cardback - p9cardback Used to identify when a seat 0-9 displays a card back. The best transformation is hash or color. If the leftmost characters of the result from this region’s transform are either “true” or “cardback”, then the region is considered to be showing a cardback. If any other result is returned, such as "false", then the chair is not considered to have be showing a cardback. Results are case-insensitive.
p0cardface0 - p9cardface0 The first card for seats 0-9; represents the entire card. The best transformation is probably hash. Typically either pXcardfaceY is used, or pXcardfaceYrank / pXcardfaceYsuit, but not both. Valid results are a case-insensitive, two character string. The first character is the rank and should be one of: “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “t”, “j”, “q”, “k”, or “a”. The second character is the suit and should be one of: “c”, “d”, “h” or “s”.
p0cardface1 - p9cardface1 The second card for seats 0-9; represents the entire card. The best transformation is probably hash. Typically either pXcardfaceY is used, or pXcardfaceYrank / pXcardfaceYsuit, but not both. Valid results are a case-insensitive, two character string. The first character is the rank and should be one of: “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “t”, “j”, “q”, “k”, or “a”. The second character is the suit and should be one of: “c”, “d”, “h” or “s”.
p0cardface0rank - p9cardface0rank The rank of the first card for seats 0-9. The best transformation is probably text. Typically either pXcardfaceY is used, or pXcardfaceYrank / pXcardfaceYsuit, but not both. Valid results are case-insensitive, and are one of “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “10”, “t”, “j”, “q”, “k”, or “a”.
p0cardface0suit - p9cardface0suit The suit of the first card for seats 0-9. The best transformation is probably text. Typically either pXcardfaceY is used, or pXcardfaceYrank / pXcardfaceYsuit, but not both. Valid results are case-insensitive, and are one of “c”, “d”, “h” or “s”.
p0cardface1rank - p9cardface1rank The rank of the second card for seats 0-9. The best transformation is probably text. Typically either pXcardfaceY is used, or pXcardfaceYrank / pXcardfaceYsuit, but not both. Valid results are case-insensitive, and are one of “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “10”, “t”, “j”, “q”, “k”, or “a”.
p0cardface1suit - p9cardface1suit The suit of the second card for seats 0-9. The best transformation is probably text. Typically either pXcardfaceY is used, or pXcardfaceYrank / pXcardfaceYsuit, but not both. Valid results are case-insensitive, and are one of “c”, “d”, “h” or “s”.
p0dealer - p9dealer Identifies if the dealer button is found for seat 0-9, or not. Color transforms are usually used for these regions, but hash, text or image transforms can be used too. If the leftmost characters of the result from this region’s transform are either “true” or “dealer”, then the chair is considered to have the dealer button. If any other result is returned, such as "false", then the chair is not considered to have the dealer button. Results are case-insensitive.
p0name - p9name Identifies the name of the player in seat 0-9. It only makes sense to use a text transform for these regions.
p0seated - p9seated Identifies whether seat 0-9 is occupied (seated) or not. Color transforms are usually used for these regions, but hash, text or image transforms can be used too. If the leftmost characters of the result from this region’s transform are either “true” or “seated”, then the chair is considered to be seated. If any other result is returned, such as "false" or "unseated", then the chair is not considered to be seated. Results are case-insensitive.
p0chipXY - p9chipXY Note: Chip scraping should *only* be used if the actual numeric bet text cannot be found elsewhere on the poker table. Text transformation is magnitudes of effort easier to accomplish. Step 1 : Ensure that the poker site uses static landings for all of the chip stacks. Step 2 : Determine the size of an individual chip, and should include any portion of the chip that is painted anywhere within the window regardless of how faded or transparent. Step 3 : Create regions for the initial base of each player's chip stacks with the size determined in step 2; p0chip00, p1chip00, ..., p9chip00. Step 4 : Create vertical stride chip regions for each player's chip stack; p0chip01, p1chip01, ..., p9chip01. These regions should perfectly surround the 2nd chip that rests above the base pXchip00. Step 5 : Create horizontal stride chip regions for each player's chip stack; p0chip10, p1chip10, ..., p9chip10. These regions should perfectly surround the base chip in the second stack. Step 6 : Optional and rare: If the vertical stride between chips in a stack is not uniform, then you will need to define pXchip02-pXchip09 for each chip in the stack. For those sites with non-uniform vertical chip strides, this means that there is a limit of 10 chips per stack that will be recognized by the engine. Step 7 : Optional and rare: If the horizontal stride between chip stacks is not uniform, then you will need to define pXchip10-pXchip90 for each stack. For those sites with non-uniform horizontal chip strides, this means that there is a limit of 10 stacks that will be recognized by the engine. In a worst case situation, there may be 100 chip regions * 10 players = 1000 region definitions required to scrape chips! (So now go look at scraping the bet text instead)
u0active - u9active These are alternatives to the p0active-p9active regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. Any transform can be used equally well with this region. If the leftmost characters of the result from this region’s transform are either “true” or “active”, then the region is considered to be active. If any other result is returned, such as "false", "inactive", "out" or "away", then the chair is not considered to be active. Results are case-insensitive.
ubalance, u0balance - u9balance These are alternatives to the p0balance-p9balance regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. It only makes sense to use a text transform for these regions.
u0bet – u9bet * New Symbol in version 2.0 These are alternatives to the p0bet-p9bet regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. It only makes sense to use a text transform for these regions.
u0cardface0 - u9cardface0 These are alternatives to the p0cardface0-p9cardface0 regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. Valid results are a case-insensitive, two character string. The first character is the rank and should be one of: “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “t”, “j”, “q”, “k”, or “a”. The second character is the suit and should be one of: “c”, “d”, “h” or “s”.
u0cardface1 - u9cardface1 These are alternatives to the p0cardface1-p9cardface1 regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. Valid results are a case-insensitive, two character string. The first character is the rank and should be one of: “2”, “3”, “4”, “5”, “6”, “7”, “8”, “9”, “t”, “j”, “q”, “k”, or “a”. The second character is the suit and should be one of: “c”, “d”, “h” or “s”.
u0dealer – u9dealer * New Symbol in version 2.0 These are alternatives to the p0dealer-p9dealer regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. Color transforms are usually used for these regions, but hash, text or image transforms can be used too. If the leftmost characters of the result from this region’s transform are either “true” or “dealer”, then the chair is considered to have the dealer button. If any other result is returned, such as "false", then the chair is not considered to have the dealer button. Results are case-insensitive.
uname, u0name - u9name These are alternatives to the p0name-p9name regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. It only makes sense to use a text transform for these regions.
u0seated - u9seated These regions are alternatives to the p0seated-p9seated regions, and are used for the player's seat. They are typically used when the player's seat changes appearance when it is the player's action, to avoid misscrapes due to change in color/size, whatever. Color transforms are usually used for these regions, but hash, text or image transforms can be used too. If the leftmost characters of the result from this region’s transform are either “true” or “seated”, then the chair is considered to be seated. If any other result is returned, such as "false" or "unseated", then the chair is not considered to be seated. Results are case-insensitive.
tablepointNNN These regions are used when the "Green Circle Button" is clicked on the OpenHoldem toolbar to "automagically" find a table to connect to. These regions must be one pixel wide by one pixel tall and must use a color transform. All tablepoint records must match the pixel colors on the casino window for it to be recognized on a connect. See {How the “Green Circle Button” finds tables} for more details.
