Access violation in RvThumbMaker while opening old rvf´s

Post by Richter.Duetting »

Hello,

I just moved a project from Delphi 6 to Delphi XE6.

If I open old texts created with the D6 application with the new version I´m getting an access violation exception.

Exception class $0000005, access violation at 0x00747018: read of address 0x039df99a

The problem seems to occur in RvThumbMaker.pas in line 338 (procedure ApplyVertically in procedure ResizeBitmap() )

I´ve also tried to open the text with the demo versions of Richview as well as ScaleRichView. Same problem.

Versions in Delphi 6:
TRichView 11.0.5
ScalerichView 2.2.1

Versions in XE6:
TRichView 14.15.1
ScalerichView 5.11.2

I can provide a sample of a crashing rvf file if necessary.

Meanwhile i found out that the problem is caused by an embedded graphic.

I confirm the problem.

Quick fix:
RvThumbMaker.pas, the line 166, instead of

Code: Select all

            if -y < SrcHeight then begin
must be:

Code: Select all

            if -y[color=red]2[/color] < SrcHeight then begin
