[GUI Plugin] Generate Cover

[Androscan]

Is it possible to have a custom resizing of the image? All the imported jpgs are shown at the same size on the generated cover.

I do not want the imported image to "Stretch image to use as cover background", I just would like to make the image a bigger size than the default.

thanks,

A

Did you try setting a larger default cover size in the options under the Dimensions tab? Importing the image after setting your desired size should work I think.

Changes in this release:

• Support the user typing \n or or <br> or <br/> as part of the title, author or series to control split across multiple lines
• Add a checkbox option to allow scaling up the cover image to fit the available area if it is too small.

This work only in "custom text" and "other options", but not in "metadata" field title and author.

There are some things which calibre just cannot do when dealing with cover images and captions. For that you need to get outside of calibre and look at the ImageMagick suite of tools, in particular the 'convert' program and its caption tag. which has been tweaked in recent revisions to properly wrap a long title line, into a display box (rather than overhanging at each end). Best yet, this can be done with variable scripting, so doing 3750 covers is as difficult as doing one. Just push 'GO' and go for coffee!

I needed/wanted 3 sections to the cover image title, and a publisher banner. The bash code looks something like this.

echo $line1 > "${captionfile}" # Investment abd Lending activities....
echo $line2 >> "${captionfile}" # O.Reg. 122/08
echo $line3 >> "${captionfile}" # Insurance Act

#captionfile has three lines in it

label="${captionfile}"
# so $label is the name of the file: caption will deal with each line in order

# the main work is done here
# lt.png is the background image on which the titles will appear

rm -f label1.png
rm -f label2.png
rm -f output1.png
rm -f output2.jpg

# create title overlay
convert -background black -transparent black -font "Liberation-Serif" -pointsize 36 -fill "dark blue" -size 720x440 -gravity center caption:@"${label}" label1.png

# then create publish-banner overlay image
convert -background black -transparent black -font "Liberation-Serif" -pointsize 36 -fill "dark blue" -size 760x80 -gravity center caption:'MANDAMUS PUBLISHING INC.' label2.png

# compose first overlay
composite -geometry +35 label1.png lt.png -blend 99 output1.png
# add second overlay to the first -> cover image
composite -geometry +20+900 label2.png output1.png -blend 99 output2.jpg

# and output2.jpg is your cover image to be used with ebook-convert --cover output2.jog

convert can also re-size images
See the sample jpg attached, It has a long first line which is wrapped and balanced in the 'write-box' which I note is actually not quite centered!

It has always worked for Custom text. I added the ability to also do it in that same tab in the Metadata section for Title, Author and Series. Title and Series are working perfectly fine for me, however I will concede that Author is not which I forgot to actually do. I will fix that shortly.

Hi Kiwidude,

is there a way to cirkumwent the gaps between the lines caused by the usage of \n or <br>?

Set the Text Padding to 0 to reduce the spacing (on the Dimensions tab).

Can I suggest a brief note be added to the Contents tab to remind users that Custom Text can include other columns via a template.

I probably knew this at one time, but I forgot and...

Hi!
I've been using this plugin in successfully for months, but I updated calibre today (*big* mistake) and now everytime I click on it, the following error arises:

...and it won't work. Any ideas please?

When did you last check for updates to this PI?

I just tried it, it (1.5.14) works fine on 1.6 (Win 64)

I've made a dozen or so covers in the past couple of hours without any problems.

I've checked this morning, and uninstalled/reinstalled GC, and the error is still occuring

[theducks]

GC has user settings stored in the: <configuration folder>\plugins\Generate Cover.json

and saved images are stored in the <configuration folder>\calibre\resources\images\generate_cover folder in case there was a damaged image

You might try a (temporary) rename of the Json file (with Calibre shut down first). All you would lose is your cover template
