I find it interesting that, for every page in this PDF which includes an image, that page is rendered as a raster image itself, including the text, which then becomes unselectable (e.g. pages 12, 14, 15). This seems like a pretty severe bug in Typst to me.
- orangepanda 4y agoInteresting. Page 5 also includes an image but text is selectable there.
- bradrn 4y agoI think the diagram on Page 5 is created within Typst itself, rather than being included from elsewhere — note that it’s a vector rather than raster image.
- rustEU 4y agoWorks for me
- bradrn 4y agoWeird… I tried it in Firefox, SumatraPDF and Acrobat Reader, and it worked in none of them for me. (In case you didn’t notice, it’s only specific pages which have the bug, namely those with raster images.)
- codetrotter 4y agoKeep in mind that some PDF readers are able to OCR text in images and thus make even bitmapped text select and copyable. It’s possible that this is why the parent to your comment was able to do so.
- tln 4y agoAgreed, that's not a feature! It's not every page with an image, eg pages 1, 5, 11 are set with text. Interestingly the rasterized text seems to use Windows-style subpixel aliasing with the red and blue fringes on the text.
- reknih 4y agoAuthor here: this is the fault of Adobe Acrobat unfortunately. I converted the thesis to PDF/A using that software and redacted my student registration number. Acrobat apparently did not like my file, therefore it converted many pages to images.
