Hi,
I am loading a .bmp image to TImageEnView:
IEImage.IO.LoadFromFileBMP(CustExamFolder+'\'+Exam2View)
Some of the files are displaying totally black. In windows, the file can be viewed with no problem. Other files display properly.
Any suggestions?
Thanks,
Matthew

Hi,
that BMP was unsupported (or malformed?). It specified a color map for 15 (5+5+5) bit RGB image.
In next minor version it will be fixed.
In the meaning time open bmpfilt.pas, replace following code...
if (InfoHead^.biClrUsed > 0) then
...with...
if (InfoHead^.biClrUsed > 0) and (xBitCount <= 8) then

I am new to ImageEn, what do I need to do to include this change? I have located the bmpfilt.pas in the source folder and changed the line of code.
Thanks

| Now recompile ImageEn packages (actually only runtime packages needs to be recompiled). |

Hi,
I am using Delphi XE2.
I loaded PKIECTRL16.dpk and PKIEDB16.dpk and compiled successfully but on DPKIECTRL16.dpk and DPKIEDB16.dpk I get the following errors:
DPKIECTRL16.DPK
contains
IERegCtrl in 'IERegCtrl.pas';
ERROR:
dcc command line for "DPKIECTRL16.dpk"
[DCC Fatal Error] DPKIECTRL16.dpk(50): F1026 File not found: 'IEREegCtrl.dcu'
DPKIEDB15.DPK
contains
IERegDB in 'IERegDB.pas';
dcc command line for "DPKIEDB16.dpk"
[DCC Fatal Error] DPKIEDB16.dpk(40): F1026 File not found: 'IERegDB.dcu'
If I keep the source folder in the lib path when I compile my app I get another error.
If I remove the source folder in the lib path and recompile my app, when I view the .bmp file it is still black.

| Is there "IERegCtrl.pas" in the same folder of DPKIECTRL16.DPK? |

The structure of the Folder is:
c:\Program files\ImageEn\Source
Folder BCBS
...
FOLDER DelphiXE2
FOLDER DelphiXE2_64
FOLDER libs
(files:)
bmpfilt.pas
...
videocap.pas
The DPKIECTRL16.DPK is in the DelphiXE2 folder
there are no .pas files here, they are in the parent folder (Source)

| Please move the content of "DelphiXE2" and "libs" into "Source" (that is the parent dir), and try to recompile. |

I am missing something. My lib path is
c:\program files\ImageEn\DelphiXE2
Is there another step I need? Is there a specific file which should be updated and put in this folder?

| In this case put "libs" content and "Source" (all .pas and .inc files) into "DelphiXE2", and try to recompile all packages. |

No luck.
I copied all the files to that folder - should I see a bmpfilt.obj file here (I don't)? I am sure I missed a step.
Thanks

| You should see bmpfilt.obj here and also bmpfilt.pas: are there both? |

Hi Fabrizio,
Success! Your prompt responses have been greatly appreciative. Do you ever sleep?
Anyway, the bmpfilt.obj has not been created but I must have missed copying other necessary files. Once I copied the folder it appears to be working. Thanks for all your help.
