exgauge - what's new

14.1.0.1 Oct 16, 2017
*NEW:   Multiple improvements for expression-like properties
*Added: a `like` b binary-operator compares the string a against the pattern b. The pattern b may contain wild-characters such as *, ?, # or [] and can have multiple patterns separated by space character. In order to have the space, or any other wild-character inside the pattern, it has to be escaped, or in other words it should be preceded by a \ character. For instance "value like `F*e`" matches all strings that start with F and ends on e, or "value like `a* b*`? indicates any strings that start with a or b character.
*Added: The 0x or 0X sequence proceed the hexa-representation of a number, in properties that support expressions. For instance, "value = 0x100" specifies whether the value is 256 ( 0x100 in hexa-representation ) 
*Added: `hex` a unary-operator converts the giving string from hexa-representation to a numeric value, or converts the giving numeric value to hexa-representation. For instance, hex(`FF`) returns 255, while the hex(255) or hex(0xFF) returns the `FF` string. The hex(hex(`FFFFFFFF`)) always returns `FFFFFFFF` string, as the second hex call converts the giving string to a number, and the first hex call converts the returned number to string representation (hexa-representation). 
*Added: a `bitand`, `bitor`, `bitxor` b binary/bitwise-operator computes the AND/OR/XOR operation on bits of a and b, and returns the unsigned value. For instance, 0x01001000 bitand 0x10111000 returns 0x00001000, 0x01001000 bitor 0x10111000 returns 0x11111000, 0x01110010 bitxor 0x10101010 returns 0x11011000.
*Added: a `bitshift` b, binary/bitwise-operator shifts every bit of a value to the left if b is negative, or to the right if b is positive, for b times, and returns the unsigned value. For instance, 128 bitshift 1 returns 64 ( dividing by 2 ) or 128 bitshift (-1) returns 256 ( multiplying by 2 )
*Added: `bitnot` x unary/bitwise-operator flips every bit of x, and returns the unsigned value. For instance, bitnot(0x00FF0000) returns 0xFF00FFFF.

14.0.0.1 Aug 14, 2017
*NEW:   Display a placeholder for missing icons, images in HTML captions.
*Added: The Key parameter of the HTMLPicture property is case insensitive, so you can display the picture using the insensitive key. For instance, <img>picA</img> is equivalent with <img>pica</img>, or <img>PICA</img> and so on.
*Added: The HTML caption shows a missing image placeholder for images whose source is missing. The missing placeholder displays the index of the icon being missing, or the key of the HTML picture being missing. 
*Added: The Version property includes the SpecialBuild number of the assembly so it provides information like Major.Minor.Build.Revison.SpecialBuild.Type...
*Fixed: Prevents "Do you want to save ..." / "Save changes...' input box, when the user opens the form in design mode, and close it.

13.0.0.4 Feb 03, 2017
*Added: `sqrt` unary-operator returns the square root of the element, so sqrt(81) returns 9, as 9^2 is 81
*Added: date(`now`) unary-operator returns the current date-time ( as double ), while the date(``) returns the current date ( no time included )
*Fixed: Prevents a memory leak when loading icons, pictures, from BASE64 encoded strings (Images method, HTMLPicture picture).

13.0.0.3 Dec 09, 2016
*NEW:   Support for EBN 1003 version.
*Added: EBN 1003 implements Colorable Region Support which defines a portion/region of the EBN object where the color of the EBN is applied. For instance, at runtime the identifier 0x1FF0000 applies blue color to all colorable parts that compose the EBN object. The EBN color is not applied to not-colorable portions of the EBNs.
*Added: `MIN` and `MAX` binary-operators to get the MIN and MAX value. For instance, the expression `value MIN 10 MAX 100` returns always a value between 10 and 100.
*Added: `sin`, `asin`, `cos`, `acos` unary-operators to get the associated trigonometric functions. For instance `2 * asin(1)` returns the value of PI

13.0.0.2 Nov 10, 2016
*NEW:   Ability to make the control's form transparent, such as a widget (using layered windows)


*Added: LayerUpdate property specifies where the control updates its content. For instance, LayerUpdate property on exLayerUpdateScreen, makes the control to draw itself on the screen ( no form behind, form transparent )
*Added: AllowMoveOnClick property allows moving the window that contains the control to a new position, as you would do by clicking the form's title/caption.

13.0.0.1 Sep 19, 2016
*NEW:   Inplace support for eXRadialMenu component ( eXRadialMenu component can host the eXGauge component )
*Added: The Handle parameter of Images method can be a string that specifies the ICO file to be loaded. The ICO file format is an image file format for computer icons in Microsoft Windows. ICO files contain one or more small images at multiple sizes and color depths, such that they may be scaled appropriately. For instance, Images("e:\working\sync.ico") method  adds the sync.ico file to the control's Images collection.
*Fixed: Captions on layers are not clearly displayed (Layer.Foreground.Caption property)

12.0.0.1 Jul 28, 2016
*Added: DPI-Aware Support
*NEW:   Support for EBN 1004 version ( DPI-Aware support ).
*Added: The exClientExt attribute of the EBN/BackgroundExt/BackgroundExtValue supports DPI values, if the number is followed by a D character. For instance, if the DPI scaling is 100%, the 16d is 16, while for a 150% DPI scaling, the 16d is 24. In other words, "top[4,back=RGB(0,0,255)]", draws a blue line on the top side of the object's background, of 4-pixels wide, no matter of DPI scaling, while "top[4D,back=RGB(0,0,255)]", draws the line of 4-pixels wide if DPI scaling is 100%, or 6-pixels wide if DPI scaling is 150% )
*Added: The coordinates of the CP clause of the Skin parameter of VisualAppearance.Add method can be followed by a D character, which indicates the value according to the current DPI settings. For instance, "CP:1 -2 -2 2 2", copies the EBN with the identifier 1, and displays it on a 2-pixels wider rectangle no matter of the DPI settings, while "CP:1 -2D -2D 2D 2D" displays it on a 2-pixels wider rectangle if DPI settings is 100%, and on on a 3-pixels wider rectangle if DPI settings is 150%.
*Added: The expression properties support `dpi`, `dpix` and `dpiy` constants that returns the current DPI setting on x/y scale. For instance, the "value * dpi" returns the value if the DPI setting is 100%, or value * 1.5 in case, the DPI setting is 150%

11.0.0.1 Jun 24, 2016
*NEW:   Ability to make the control's form transparent, such as a widget (using regions)


*NEW:   Ability to include transparency of a picture in the clipping region. Previously, all transparent pixels of the picture are clipped off 
*Added: LayerClipToParent property indicates if the LayerClipTo method clips the control itself, parent or the root/owner of the control.
*Added: Layer.LayerClipToAlpha property 
returns or sets a value that indicates the value of the alpha channel to be included in the LayerClipTo region.
*Added: ClipPicture.AlphaFrom property Gets or sets a value that specifies the alpha-byte to start clipping the picture from. By default, the AlphaFrom property is 0.
*Added: ClipPicture.AlphaTo property Gets or sets a value that specifies the alpha-byte to end clipping the picture to. By default, the AlphaTo property is 254. 255 is an opaque pixel
