Help & Questions / Re: Sample code for APNG Support
« Last post by Isaev on 10 May 2017, 14:00:29 »
Basically you need to load the image into TMultiImage and then convert each frame to VCL TBitmap descendant which you can easily display on form.
Code: [Select]
Var
  FImage: ImagingClasses.TMultiImage;
begin
  FImage := TMultiImage.Create;
  FImage.LoadMultiFromFile('post_63_33.png');
  //img1.Picture.Bitmap.Assign(FImage); ???
  FImage.Free;
end;
How to display animation in TImage? Whether it is possible or I need ExtraGIF?
write an example of use if it isn't difficult, for apng file

Suggestions, Feature Requests, Contributions / TImage differential
« Last post by syncovery on 24 December 2016, 15:50:33 »
Dear image developers,
please suggest me a simple way to compare two TBaseImage objects and get third differential image object.


my question is very relative to this post
http://galfar.vevb.net/imaging/smf/index.php/topic,274.0.html

but i want to get as output smaller image. e.g Picture 1( Desktop ) - Picture 2( Desktop + Dialog) = Picture 3( Dialog ) but small size image of the dialog only.

thanks in advance,

Suggestions, Feature Requests, Contributions / DX10 DDS and BC5/7 compression
« Last post by zilav on 20 December 2016, 18:18:00 »
Any chance for DX10 DDS format and BC5/BC7 support?
Vampyre Imaging is the only pascal library which supports DDS files without DirectX requirement and works perfectly for handling textures DX9 games, but newer ones often use BC5/7 comressions.

I've just got my First Texture - absolutely stunning - couldn't have done it without the amazing Vampyre. The same Lazarus pascal code works identically in Ubuntu and Windows 8.
Thank you thank you thank you.

Hi,

i created a patch to introduce a new option for the Jpeg2000 decompression.
It allows to control wether the decompressed output will be upscaled or not.

This is essential for us (medical image viewer) since we need the data to stay "untouched" and unscaled.

Btw, have you considered moving your repositories to github? I would love to see more delphi libraries there for the community ;)

Thx for your work, the lib is awesome.

Help & Questions / Re: How to determine image size
« Last post by Galfar on 20 March 2015, 16:34:44 »
This would be very helpful but unfortunately is not supported.

For each image format this must be done differently but at least the most common formats (JPEG, PNG) would be nice.
