[GUI Plugin] Resize Cover - Page 4

gingerbeardman · 11-14-2017, 09:19 AM

So the issue in the code is it using KeepAspectRatioByExpanding parameter.

Changing that to KeepAspectRatio fixes the behaviour.

Make sure you set your reader screen dimensions (Width and Height) on the plugin.

Modified plugin attached. Based on the one from post #39

I have the same problem as in Post #40. I want the height to be a specific value, but the PI changes the width to the value in the setting. Using the version in #46.

Can it be changed so the proportionally resized cover has a fixed height, not width as at the moment?
Thanks

My version of the plugin, attached above, does that already.

If you're not seeing that, please can you give an example image and your current plugin settings.

I suspect you have not set the dimensions in the plugin?

I have it set to 768x1024 (Sony Reader) and all of my images are 1024 pixels high and various widths.

cheers

Here is what my version of the plugin (KeepAspectRatio) does with portrait images.

Look only at the KeepAspectRatio column.

I love this plugin but the latest version of calibre removed it for some reason. I reloaded it and while it's listed under my plugins it no longer has the button on my toolbar....? Not sure how to get it back.

Look at your toolbar. Is there an arrow on the right?

(it got crowded off )
otherwise:

Preferences:Toolbars: <select type(s)>:select from left: <optional order>

This is a continuation of this thread ==>> Resizing covers

Firstly a housekeeping problem, I removed the version Narengil uploaded to post #39. I think its labelled version 1.04. If anyone has it could they upload it somewhere and PM me a link, I'd like to restore it until we get this issue resolved.

I've had a look at the experimental unofficial versions posted by Narengil and gingerbeardman and IMO none of them is a viable release candidate. They are not explicit as to which dimension has a fixed value and which is to be adjusted to maintain the original aspect ratio. If you leave the one you want adjusted as 0 that configuration will not be saved and no message is issued.

IMO what's needed is radio button triplet - fixed size, fixed width, fixed height. I don't know if Qt allows for such a thing in a table column, if not then they can be placed outside the list like the "proportional/non proportional" buttons shown in post #36.

Just a quick note, you can resize the cover image with the Calibre editor.

We know Jon - but the plugin can resize the covers of a million books with ONE CLICK.

Can the official plugin resize keeping the cover's aspect ratio and use Calibre's lossless compression?

BetterRed · 01-26-2020, 05:24 PM

No and Don't Know

I don't care

The plugin works by resizing the current cover to the selected size. With the keep aspect ratio, it resizes the cover to fit within the selected size. Whether the height or width is used, depends on the relative aspect ratios of the image and the selected size. This feels like the right way to do it. The size selected is probably related to something else such as the resolution of an ereader. The resize is to fit the cover within that size.
