Hello
Delphi XE2, Windows 64 bit, ImageEn 4.1.4
a) With ImageEnMView.GridWidth := 3 I would like to be able to load 8 images and have grid location #5 empty or null. Code snippet 1 below works fine if the second if statment is remarked out and all 8 images are loaded. However, if code snippet 2 is implemented and I try to either skip the #5 grid space (by remarking out the code folloiwng the second if statement) or use a null value in the #5 location the code fails.
Code Snippet 1
if formViewPhotographs.ImageEnMView1.MultiSelectedImagesCount = 8 then
begin
for I := 0 to 9 - 1 do
begin
formViewPhotographs.kbmMemTablePhotos.First;
formViewPhotographs.kbmMemTablePhotos.MoveBy(formViewPhotographs.ImageEnMView1.MultiSelectedImages[I]);
with ImageEnMView1 do
begin
InsertImage(I);
SetImageFromFile(I, tempPtPhotoPath + formViewPhotographs.kbmMemTablePhotos.FieldByName('FileName').AsString);
ImageBottomText[I].Caption := formViewPhotographs.kbmMemTablePhotos.FieldByName('EXIF_OriginalDate').AsString ;
end;
end;
end;
CodeSnippet 2
if formViewPhotographs.ImageEnMView1.MultiSelectedImagesCount = 8 then
begin
for I := 0 to 9 - 1 do
begin
formViewPhotographs.kbmMemTablePhotos.First;
formViewPhotographs.kbmMemTablePhotos.MoveBy(formViewPhotographs.ImageEnMView1.MultiSelectedImages[I]);
if I <> 4 then {second if statement}
begin
with ImageEnMView1 do
begin
InsertImage(I);
SetImageFromFile(I, tempPtPhotoPath + formViewPhotographs.kbmMemTablePhotos.FieldByName('FileName').AsString);
ImageBottomText[I].Caption := formViewPhotographs.kbmMemTablePhotos.FieldByName('EXIF_OriginalDate').AsString ;
end;
end
else
begin
with ImageEnMView1 do
begin
InsertImage(I);
SetImageFromFile(I, null);
end;
end;
end
end;
Suggestions?
b) in a 12/11/2011 post there were comments that the properties SelectionGridWidth and SelectionGridHeight were to be added to the ImageEnMView component with the next minor upgrade. Are there still plans to expose these properties?
TIA
John

Why not just call InsertImage(I) without SetImageFromFile to leave "I" empty? SetImageFromFile(I, null) is not valid, of course.
Instead of SetImageFromFile(I, null), you could call SetImage(I, ThumbWidth, ThumbHeight, ie24RGB).
About (b) please could you past the topic link? |
