Extends TImage with JPEG support and image manipulation like flip, invert, saturation, lightness, graying and more. Easy to use. Correctly handles image aspectratio. Requires PASJPG10.ZIP by NOMSSI NZALI Jacques H. C.

Note: if you have troubles with PASJPG10.ZIP when recompiling the library (i.e. installing the component), then apply the following patches by hand:
- rename file JMEMNOBS.PAS to JMEMWIN.PAS
- in file JMEMMGR.PAS at line 41 change JMEMNOBS to JMEMWIN
- if you’re installing the component into Delphi 3: 
in file JIDCTRED.PAS at line 452 change JSAMPLE(dcval) to dcval. The rest of the line remains unchanged

 

Version Release date What's new
2.07 13 may 1999 - added full support for Delphi 4 even in the trial version (BPL included)
2.06 26 nov 1998 - added event OnSelection to allow the end user to select a rectangle on the image

2.04 may 1997 - correctly loaded an image when using Windows with 256 colors and ForceGray property set to true
