Hi

My project is getting crashed when tried to Export a graph/chart

in the right side of window there is Compression with two radio buttons
LZW
RLE
if i select the RLE
after saving the graph it gives an error saying
Invalid Parametrs Used... and application will crash which is a serious bug

can anybody please suggest me the correct way to Export the Imgae in TIFF format selecting RLE as the option?

Hello,

I've been able to reproduce your problem here and have fixed it for the maintenance release due out in September.

Please note that the GDI+ TIFF encoder will encode RLE compression only for 1bpp input. This means having to convert the 32bpp tchart bitmap to a 1bpp bitmap before exporting to RLE compressed TIFF files, a conversion which is very slow in managed code and which produces a monochrome TIFF file.
