Help & Questions / Re: Get orientation from EXIF

You cannot get this info from Imaging alone.
You can try something like CCR.EXIF for Delphi or fpexif for FPC/Lazarus.

Help & Questions / Re: TIFF

Hi,
yes that would be pretty quick change to support loading only single user-specified page from multi-page image.
Some long missing "basic info about image without decoding all the pixels and stuff" would be useful
to first get you the number of pages in a file.

Help & Questions / Re: TIFF

Hello, Galfar. I like your library for its accessibility in lazarus and ease of use.
However, I have a few suggestions. One of them is:
Is it possible to download multi-page documents (tiff) one page at a time. For example, my tiff files may contain about 180 pages scanned in high resolution. When downloading a file less than 1mb in size, several tens of megabytes of RAM is consumed. Since only 1 is needed for the display..3 pages, I could dynamically load the necessary ones.

Bugs And Other Insects / ImagingPcx.pas doesn't compile
Last post by cathalex - 6 May 2021, 16:57:58
I downloaded imaginglib0264.zip and tried to compile it using BuildLibraryFPC.sh.  Tje const declarations in the function TPCXFileFormat.LoadData, namely:
function TPCXFileFormat.LoadData(Handle: TImagingHandle;
  var Images: TDynImageDataArray; OnlyFirstLevel: Boolean): Boolean;
const
  ifMono: TImageFormat = TImageFormat(250);
  ifIndex2: TImageFormat = TImageFormat(251);
  ifIndex4: TImageFormat = TImageFormat(252);

generates the error messages:

ImagingPcx.pas(94,26) Warning: range check error while evaluating constants (250 must be between 0 and 225)
ImagingPcx.pas(94,43) Error: range check error while evaluating constants (250 must be between 0 and 225)
ImagingPcx.pas(95,28) Warning: range check error while evaluating constants (251 must be between 0 and 225)
ImagingPcx.pas(95,45) Error: range check error while evaluating constants (251 must be between 0 and 225)
ImagingPcx.pas(96,28) Warning: range check error while evaluating constants (252 must be between 0 and 225)
ImagingPcx.pas(96,45) Error: range check error while evaluating constants (252 must be between 0 and 225)
ImagingPcx.pas(379) Fatal: There were 3 errors compiling module, stopping
Fatal: Compilation aborted

I am using the Free Pascal Compiler (fpc) for x86_64 version 3.2.0 (released 2021/04/29) on Linux.

Is there anywhere to report bugs other than in this forum?

Last post by Galfar - 1 April 2021, 01:20:58
I actually switched my other project to MPL2 just today and will do the same with Imaging in coming future.
The original notice in the code is I think from 2003 and I haven't looked at the licenses since then.

Yes, the homepage and SF are hopelessly outdated, sorry to keep you on 2009's version for so long :)
