GraphicEx - a Delphi image loader library

GraphicEx

GraphicEx is an addendum to Delphi's Graphics.pas to enable your application to load many common image formats. This library is primarily designed to load images as background (buttons, forms, toolbars) and textures (DirectX, OpenGL) or for image browsing and editing purposes as long as you don't need to save images. Currently only TTargaGraphic also supports saving an image. GraphicEx is open source under the Mozilla Public License (MPL).

The code here includes some bug fixes and enhancements I have never made available on my homepage. Since I cannot work on this lib any longer I open it up for forks and contributions by others if they interested. If there's significant feedback with fixes and new code I'm willing to publish new releases on my homepage as well.

IDE and compiler versions

Library was tested under various IDE from Delphi 7 up to Delphi 10 Seattle, both win32 and win64. Right now, it works only with VCL, but support of FMX is also planned in some near future.

Compilation

Almost all the code here is native Delphi code, so compiling is straight forward. The only exception is DelphiZlib which is included in this repository as 3rd party. Good thing, it is already compiled for both win32 and win64, so C compiler is not necessary after all, Delphi is enough.

Just add all the units in root folder of GraphicEx to your project and also from subfolders and that's it. Now all the graphic formats are available: line like

Image1.Picture.LoadFromFile(OpenPictureDialog1.Filename);

is everything which is needed to load any of files listed above.

Multi-language support

Recent version greatly simplifies writing international application: there is just no worries about translating GraphicEx strings and error messages: they are already translated and will be fetched in correct language at runtime. So far, there are translations to German, French, Italian, Spanish, Catalan, Polish and Russian and even two English versions: US and UK which differ by spelling of 'color'.
