File size/ cropping dimensions on the export

[Olli]

Hi!

Is there a way to fish out the original cropping dimensions after using the resize command when exporting the photo for the Web, and to make them visible on my website?

It would nice to be able to show the original cropped size in stead of merely stating that all the photos on my site are at least 2''' pixels on the shortest dimension.

Any photo on the web has a specific known size in pixels. But how to display it on your web site depends on the software you are using to create the web site.

Technical correction ... export does not crop, it resizes. Cropping happens in the Develop module. I presume you are asking for the resized dimensions of your export.

While cropping does not actually occur until an export JPEG is created, the export uses the cropping instructions in contained in the metadata. It writes this information in the XMP section of the exported file. You will find this information in the ImageWidth and ImageHeight fields of the XMP section of the header. If you resize in Export, the new size not the original crop dimensions will be written there.

So if I understand you correctly, it is not possible to show the original crop dimensions, only the dimensions resized in Export. However, it should not be technically impossible to have the pre-resize dimensions stored somewhere.

Yes, if you examine the header from your exported JPEG with EXIFtool, you can see what I am talking about. There are other fields available to the user that you can manually insert the original cropped dimensions. Often many Web applications used for creating pages of web photos either as a page to review or as an automated slideshow will overlay information from the file header. Typically, the fields displayed are the Title and the Caption fields. You can insert the cropped dimensions in one of those and display it on your web photo view. I do not know of a means of automating this task.
