20.2.2014: V3.12.2'
+ The 32 bit edition now does JPEG2000 decoding (JPXDecode)
* change in drawing code to avoid fine lines in images consisting of several parts (GDI+ Rounding)
- fix problem with Tw handling
- COMPDF_ScreenToClient did not provide correct information it was supposed to
COMPDF_ScreenToClient can be used to convert a screen coordinate into a logical page x, y coordinate
- ScreenToPage now works as documented
12.3.2014: V3.12.3
* smarter caching which can be also controlled by this new commands: COMPDF_SetMaxCachePixels
COMPDF_SetMaxCachePixelsThumbs,
COMPDF_SetMaxCachePathLockTime
+ added additional functionality to command COMPDF_DisableSecurityOverride to enable print and high quality print.
- improved text stamping, "numformat=..." did not always work as expected.
- VCL: Improve popup menu handling
2.4.2014: V3.12.4
+ Support for text state "Tz"
* better support for hyperlink with launch action
- fix problem with bitmap masks which are inverted
22.3.2014: V3.12.3''
- with R2 PDF security (40bit) the HQ-Print Flag was evaluated, although it is only used in R3 security (128bit)
23.4.2014: V3.12.6
- fixed: DrawObject text was drawn rotated by 180 degrees
+ It is now possible to add transparency to draw object texts
+ It is now possible to specify the font of draw objects
- fixed problem with Type1 fonts
+ added possibility to set origin position to for added draw objects (see demo).
- fixed function pdfPrint
- PageToScreen did not correctly revert the coordinates provided by ScreenToPage
30.4.2014: V3.12.7
* There is an updated JBIG2 plugin available online - it fixes problems which occurred with incomplete JBIG2 data streams.
+ wpdfSetGlobalParameter("StopIGDIPlus", 0) can be called before the DLL is unloaded to avoid trouble with GDI+ which under certain circumstances cannot be shutdown in finalization of a DLL. The VCL will automatically make this call before the FreeLibrary in "StopEngine".
* changed code to handle "EI" which marks the end of an embedded image.
- fix AV which occured when no file was loaded and clicking with right mouse button
28.4.2014: V3.12.6'
- when font names in PDF used '-' in their names it was required that they were embedded
- Find method changed zoom to full page - it now will not change zoom anymore
- option "MEMORYSIZE" was broken in function pdfprint
+ pdfPrintW can now alo load data from a memory buffer provided as parameter data + datalen
24.6.2014: V3.12.8'
- fix problem when printing was started with a page which uses a different orientation than page 1
+ use COMPDF_SetSaveMode with parameter 1024 to remove PDF/A marker when saving file
11.6.2014: V3.12.8
- small change in font handling to render subset fonts which did not define encoding
1.7.2014: V3.13.1
* optimized loading routine will open PDF data a lot faster
- improved threading routine fixes some stability issues
+ With SetGlobalParameter("DisableThreading=1") multithreading can be disabled. If highest possible stability is required, we recommend this Setting - it will still operate very fast due to the added optimation.
+ WPViewPDF.SetGlobalParameter now stores the parameters if the DLL was not yet loaded. The parameters will be sent to the DLL after the DLL was loaded.
+ SetGlobalParameter("MinimizeMemoryUsage=1") will disable caching of the PDF page paths. Text selection is impossible in this case.
- fix problem with ScreenToPage/PageToScreen on rotated pages
- fix problem when printing was started with a page which uses a different orientation than page 1
+ use COMPDF_SetSaveMode with parameter 1024 to remove PDF/A marker when saving file
16.7.2014: V3.13.1''
- UseImage did not work with wpPageWidthPC and wpPageHeightPC
- COMPDF_StampMetafile, COMPDF_StampMetafileUnder scale incorrectly
The behavior was not changed for backward compatibility, but we recommend to call command( COMPDF_StampMetafile_Scaling, 72 ) to fix this problem.
+ decode 2 bit grayscale images
- command COMPDF_MakeGetMEMORY did not return the required size when passing a null pointer but -2
- when rendering left aligned text draw objects they became centered
+text draw objects can now also be right aligned
+SaveSelection did not work correctly with an invisible control
20.7.2014: V3.20
WPViewPDF now includes integrated and very fast JBIG2 decoding. JBIG2 is an Image format used by many scanning applications.
You only have to copy the correct DLL, there is one for 32 and for 64 bit.
28.7.2014: V3.20.1
- fix save problem which occurred in few PDF files when objects were entirely empty
6.8.2015: V3.25.4.8
- Patterns are now not filled anymore. There are PDF files which draw pattern over the page which would otherwise erase the contents
- fix problem with XREF syntax used by few PDF files
- fix problem with PDF files consisting of appended singular PDF files
+ SetGlobalParameter("LoadAllEncodingNames=1") activates the use of names to locate glyphs in fonts. This works better in some PDF files but can cause in problems if the names were not correct (which we sometimes saw)
30.8.2015: V3.25.4.8''
- accept * as character for a PDF name
- experimental: interprets code EI in embedded images also if not proceeded by whitespace
when SetGlobalParameter('LazyDecodeEI=1') was used
- GOTOPREV was not working when the end of the last page was visible.
17.8.2015: V3.25.4.8'
- fix for prediction decoding for 1 bit data
- update to 1 bit image decoding to avoid inverse display
- change in standard GDI renderer to fix problem with subset fonts
25.9.2015: V3.25.4.9'
- fix problem with prediction decoder which was not defining BitsPerComponent
18.9.2015: V3.25.4.9'
- in rare cases embedded images in CCITT fax compression were not read completely
9.9.2015: V3.25.4.9
- fix problem with sometimes visible hairline stripes around rectangles.
- fix problem with screen update after programmatic page selection.
* After moving a page the new current page is the first page which was moved.
18.12.2015: V3.26'
- fix rare problem when saving to new PDF
- fix a memory leak problem which occurred on rare PDF files
12.12.2015: V3.26
* watermarks are now clipped by BBox property
+ support for grayscale indexed color space
