All rights reserved. But I am scratching my head... Is it possible to use one and the same TImage component in order to save to JPG, BMP and PNG formats just by setting the target file name extension appropriately? code to put the image onto the bitmap ... UpdateMyImages; //This creates the image in gTOffScreenBmp //.

What needs to be done now is to transfer the content to the proper container, which was done by Assign operations then followed by an SaveToFile from the object involved.

First the transparency: This is code from the original LoadPNGintoBitmap32, the critical parts are marked with comments: PNGObject := TPngObject.Create; PNGObject.LoadFromStream(srcStream); destBitmap.Assign(PNGObject); // <--- paint to destBitmap's canvas with transparency (!)

The example on their website shows that the mode should be dmBlend if theres any transparency in the loaded PNG image. this contact form Variant error, please help5. All rights reserved.

It is giving the weird exception above. For a better animation of the solution from NDSolve How can tilting a N64 cartridge cause such subtle glitches? I wouldn't have thought of system restore. http://electrictricycle.net/cannot-assign/cannot-assign-a-nil-to-a.html Borland vs.

So, the solutions are: Do not use TBitmap32; use Vcl.Imaging.pngimage.TPngImage do draw directly on target bitmap (screen, etc.) – this is the most compatible way that deals correctly with various PNG Just have to put in the correct number... I would have thought that one should tell TImage what format its Picture should be saved in, but I cannot find any such property/command. You have to convert the TImage.Picture.Graphic object to the appropriate TGraphic class type first, then save that instead.

THe JPG was saved as before via the JPGImage object and it produced a filesize of 629 kb, whereas the purported PNG image ended up as a size 17505 kb file!!!
