Do you have a specific place where you think i return the wrong message ? I mainly use this link, for the psd specification : https://www.adobe.com/devnet-apps/photoshop/fileformatashtml/ @Rostislav : > I don't think you need the checks, it was pointed out that > ff_set_dimensions already does that. > Also IIRC lavc doesn't support widths or heights over 16384 anyway. Andreas ask why i choose 30 000 for check widths/heights And the choice come from the Adobe documentation : "Supported range is 1 to 30,000." But i doesn't know about the 16384 limit, in lavc. I wrongly suppose, it was int max So if this is the real limit value is under 30 000, you're right, the check is not need.
