ImageEn support back #19

Closed mhietan closed 2 years ago

mhietan commented 2 years ago

Hi,

Please add ImageEn support back. Please note! after 14.5.2022 some changes thumbnail drawing is broken. I'm using these in my project.

in addins.inc: // ImageEn SUPPORT {$DEFINE USEIMAGEEN}

VirtualThumbnails.pas:

function SpMakeThumbFromFileImageEn(Filename: string; OutBitmap: TBitmap; ThumbW, ThumbH: Integer;
  BgColor: TColor; Subsampling, ExifThumbnail, ExifOrientation: Boolean; var ImageWidth, ImageHeight: Integer): Boolean;
{$ENDIF}

uses {$IFDEF USEIMAGEEN} ImageEnIo, ImageEnProc, hyieutils,ievision, iexBitmaps, iexHelperFunctions, {$ENDIF}

I readded the code for USEIMAGEEN. I cannot say if the code is compiling or working.

mhietan commented 2 years ago

Thanks. I will test it tomorrow.

Hello,

Thank you, it works now perfectly.

Only few additions needed: To VirtualThumbnails.pas, cause now it misses few uses:

uses
{$IFDEF USEIMAGEEN} ImageEnIo, ImageEnProc, hyieutils, iexBitmaps, iexHelperFunctions,{$ENDIF}
  Types,
  Math;
procedure TCustomThumbsManager.FillImageFormats(FillColors: Boolean = True);

Also in to Addins.inc file:

// ImageEn SUPPORT
// You may need to add Path to ImageEn: Delphi Compiler, Windows 64bit, Search path \ImageEn\Source\Delphi11Alexandria_64

// {$DEFINE USEIMAGEEN}
romankassebaum commented 2 years ago

I added your changes. Please check again.

mhietan commented 2 years ago

Now its okay. Big thank you!

Note for other users: About the FillImageFormats. It depends on your needs, for ex. coloring might need to change. :)

mhietan commented 2 years ago

For the Addins.inc one more note, sorry :)

// ImageEn SUPPORT // You must add the ImageEn package to the VirtualShellToolsD.dpk "Requires" section PKIECtrl28 // You may need to add Path to ImageEn: Delphi Compiler, Windows 64bit, Search path \ImageEn\Source\Delphi11Alexandria_64

// {$DEFINE USEIMAGEEN}

romankassebaum commented 2 years ago

I improved the notes.
