Image height in table

[LarsK1]

Hi everyone,
I'm currently trying to automate our reporting. Therefore we do want to use your amazing table feature.
But we keep on failing, how to manually resize images in cells or even better specify a fixed height.

This is our current code:

Dokument = Template(auftragsnummer)
	Dokument.author = "Test"
	Dokument.oversized_images = "DOWNSCALE"
	Dokument.set_image_filter("DCTDecode")
	Dokument.add_page()
	Dokument.set_font("Arial", size=12)
	Tabelle: Dokument.table
	with Dokument.table(text_align=("CENTER", "CENTER")) as Tabelle:
		ueberschrift = Tabelle.row()
		ueberschrift.cell("Raum - Beschreibung")
		ueberschrift.cell("Bild")
		for Inhalt in zeile:
			Reihe = Tabelle.row()
			Reihe.cell(Inhalt[0], padding=(0, 10, 0, 0))
			Reihe.cell(img=bild_umwandeln(Inhalt[1]), img_fill_width=False)
	Dokument.output("Testpdf.pdf")

This creates the following pdf: Testpdf.pdf

How can we specify a fixed image size / row heigth?

Thanks for your help in advance!
Lars

Hi @LarsK1 🙂

I'm a bit in a hurry right now, but just so you know, there this very recent PR regarding images in templates: #1119

Unless @gmischler beats me to it first, I'll test the code sample you provided.
Sadly your code is not executable "as it is" (cf. https://stackoverflow.com/help/minimal-reproducible-example ), so it will take me a few minutes to reproduce your problem. Maybe I'll find the time to do that tomorrow 😊

Hi @Lucas-C ,
thanks for your kind reply.
Here you go:

import fpdf

zeile = (("Example 1", "https://larskusch.b-cdn.net/wp-content/uploads/2023/12/Lostplace-Hotel-062-980x1470.jpg"), ("Example 2", "https://larskusch.b-cdn.net/wp-content/uploads/2023/12/Lostplace-Hotel-059-scaled.jpg"))

Dokument = fpdf.FPDF()
Dokument.add_page()
Dokument.set_font("Arial", size=12)
Tabelle: Dokument.table
with Dokument.table() as Tabelle:
	ueberschrift = Tabelle.row()
	ueberschrift.cell("Raum - Beschreibung")
	ueberschrift.cell("Bild")
	for Inhalt in zeile:
		Reihe = Tabelle.row()
		Reihe.cell(Inhalt[0], padding=(0, 10, 0, 0))
		Reihe.cell(img=Inhalt[1], img_fill_width=True)
Dokument.output("Test.pdf")

EDIT: Updated code, to match the problem

So first, I tested your script with debug logs & warnings enabled, and it works fine:

Now, having fixed height rows has been mentioned in the past:

• have you tried passing line_height to FPDF.table()?
• cf. SVG inside table cell is stretched forcefully #1059 (comment)
• cf. Is there a way to set row height according to the highest column height in the row without calculating the highest column height? #494

I hope those "pointers" will help solve your problem? 😊

Hi,
thanks for your quick response. Yes, the script does work. That's true. I've updated the demo code, my issue is, that with bigger images only one image per page is shown. Our need would be to show two images on every page, therefore the individual image would need to be scaled down. (Only changing the image pixel size didn't help at all)
Test.pdf
This page show's the ideal condition (except, that when using the line_height the heading is way to big as well)
Test - how I would like it.pdf

Alright, I think I understand better your problem now. Thanks for providing examples.

So you have two requirements:

• having at least two table rows with images on each page
• having images filling the cells that contains them

Given your images dimensions, the only solution IMHO is to adapt the width of the table columns:

from fpdf import FPDF

ZEILE = (
    ("Example 1", "https://larskusch.b-cdn.net/wp-content/uploads/2023/12/Lostplace-Hotel-062-980x1470.jpg"),
    ("Example 2", "https://larskusch.b-cdn.net/wp-content/uploads/2023/12/Lostplace-Hotel-059-980x1470.jpg"),
)

doc = FPDF()
doc.add_page()
doc.set_font("Helvetica", size=12)
with doc.table(col_widths=(4, 3)) as table:
	ueberschrift = table.row()
	ueberschrift.cell("Raum - Beschreibung")
	ueberschrift.cell("Bild")
	for Inhalt in ZEILE:
		Reihe = table.row()
		Reihe.cell(Inhalt[0])
		Reihe.cell(img=Inhalt[1], img_fill_width=True)
doc.output("discuss_1120.pdf")

Hi,
thanks for your help. That worked really well. I must admit, I really don't completly understand, why setting the columns width adjust the rows height 😁, but I works like a charm. Many thanks for your help!!!
