GraphLCD base package Revision History
--------------------------------------
2021-02-08: Version 2.0.3
- Remove usage of FcFini() to prevent race conditions with other users of
fontconfig
2021-01-07: Version 2.0.2
- Remove non-standard "uint" file type which does not exist in some
environments. Thanks to Conrad Kostecki!
- Fixed remaining compiler warnings
2021-01-04: Version 2.0.1
- Replace libvncserver-config with pkg-config to make vncserver driver work
with later libvncserver versions. Thanks to Conrad Kostecki!
2020-08-14: Version 2.0.0
- If a required font file is neither in "FontPath" nor in the "fonts"
subdirectory of "SkinPath", then (if available) fontconfig is used to search
all common system font paths for the wanted font file
2018-11-10: Version 1.0.2
- Improved "trim" function which doesn't cause negative size_type values
2018-05-10: Version 1.0.1
- Fixed building against freetype 2.9.1
2018-04-08: Version 1.0.0
- New driver "st7565r-reel"
- New driver "usbserlcd". With this driver it is possible to diy an USB LCD.
See also: https://github.com/M-Reimer/usbserlcd/
- branch "touchcol" merged back to "master"
- Tag name is now always passed if "GetToken" is called.
This makes it possible to use graphlcd-base without bothering about token id's
- "alphacool" and "sdcmegtron" are now predefined entries in graphlcd.conf
- Makefile optimized for packaging
2011-05-01: branch touchcol, first commit
- glcddrivers changes / enhancements:
- support for colour bitmap data
- support for colours either by using pre-defined colour names or 0xRRGGBB / 0xAARRGGBB (though no alpha channel is supported yet)
- adapted/added methods SetScreen(), SetPixel()-methods in base-class and driver-classes for new colour enabled bitmap data
- added support for events (supported for now: simple touch events)
- added support for requesting and setting driver features
- added GetBackgroundColor(), GetForegroundColor() -> gets default back/foreground colour
- fixed compiler warnings (missing parameters in printf(), ...)
- dm140glnk: bugfix: changed type for vendor and product to 'signed'
- serdisp:
- added support for touch events
- cut support for serdisplib version < 1.95 (-> simplifies code)
- added basic support for GPIs (eg. enable/disable touchpad)
- rotate only when graphlcd-setup says so
- UTF8 should work fine but is not tested very well yet
- vdr 1.3.x should be supported as well but support for it is deprecated and will be removed (-> cleaner code)
- glcdskin changes / enhancements:
- improved update policies (update only display regions that require update) - w/o this displays like l4m320t would be unusable w/ graphlcd.
- new objects / attributes / features for skins:
- increased skin version to 1.1, version info is now verified before loading a skin
- objects can now trigger actions (eg. when touching an object it may trigger a VDR 'Key'-event)
- 'scrolltext' is deprecated and is now an aliases for 'text'
- new object 'button'
- new attribute 'valign': vertical alignment
- attribute 'bgcolor': sets background colour for object (whereas 'color' sets foreground colour)
- new attributes 'alttext' and 'altcondition' for object 'text' (if 'altcondition' is true, 'alttext' is evaluated and used)
- scrolling/looping attributes for 'text': 'loop', 'scrollmode', 'scrollspeed', 'scrolltime'
- new attribute 'default' for variables:
shortcut for <variable id="name" value="value1" condition="somecondition"/> <variable id="name" value="value2"/>:
<variable id="name" value="value1" condition="somecondition" default="value2"/>
this will actually be stored in two variable entries (exactly as in the first version)
- new entity 'condblock': combines variables that use the same condition
<variable id="id1" condition="condition1" value="val1"/>
<variable id="id1" value="valdefault1"/>
<variable id="id2" condition="condition1" value="val2"/>
<variable id="id2" value="valdefault2"/>
can now be simplified to
<condblock condition="condition1">
<variable id="id1" value="val1" default="valdefault1"/>
<variable id="id2" value="val2" default="valdefault2"/>
</condblock>
attention: variable-definitions in a condblock must not contain condition-attributes.
- XML parser:
- parser method XmlParse() optionally may pass an error string
- text-objects may now contain combinations of tokens, constants, and variables
- evaluation of variables in text-objects is now delayed from parsing time to runtime
- attention: 'condblock' and attributes 'alttext', 'altcondition' are case studies for now and may be removed
