Hmm... are we sure the GDI measurement will work always for the fonts for which we must use DirectWrite? For example, the color fonts? If GDI might fail for some fonts, perhaps leaving the metrics code in w32_dwrite_text_extents, and then _overriding_ that by GDI values if available, would be safer? Thanks.

The attached patch fixes this by using the GDI measurement for the vertical size of text. Doing the same with DirectWrite would be too expensive, and would imply using the "layout" parts of DirectWrite, to get the same results most of the time. Horizontal extents is different, we need to keep using DirectWrite for that. --------------0cpI14QPugXTTpxK0y0cRtmy Content-Type: text/plain; charset=UTF-8; name="0001-w32-fix-problem-with-font-vertical-measurement-for-d.patch" Content-Disposition: attachment; filename*0="0001-w32-fix-problem-with-font-vertical-measurement-for-d.pa"; filename*1="tch" Content-Transfer-Encoding: base64 RnJvbSA2MDE2NTVhNGVmZmM3YjY4NDQ4ZTgwYjdiNzk4YTczOGQ2NmM3Y2IxIE1vbiBTZXAg MTcgMDA6MDA6MDAgMjAwMQpGcm9tOiBDZWNpbGlvIFBhcmRvIDxjcGFyZG9AaW1heWhlbS5j b20+CkRhdGU6IFR1ZSwgMSBBcHIgMjAyNSAxMDoxODoxNCArMDIwMApTdWJqZWN0OiBbUEFU Q0hdIHczMjogZml4IHByb2JsZW0gd2l0aCBmb250IHZlcnRpY2FsIG1lYXN1cmVtZW50IGZv ciBkd3JpdGUKCkdseXBoIGJ5IGdseXBoIG1lYXN1cmVtZW50IG9mIHZlcnRpY2FsIHNpemUg aXMgdG9vIGV4cGVuc2l2ZSB3aXRoCkRpcmVjdFdyaXRlLiAgR0RJIG1lYXN1cmVtZW50IGZv ciB2ZXJ0aWNhbCBzaXplIGlzIGdvb2QgZm9yIERpcmVjdFdyaXRlCnRvby4KCiogc3JjL3cz MmR3cml0ZS5jICh3MzJfZHdyaXRlX3RleHRfZXh0ZW50cyk6IFVzZSB0aGUgdmVydGljYWwK bWVhc3VyZW1lbnQgZnJvbSBHREkuCiogc3JjL3czMmZvbnQuYyAodzMyZm9udF90ZXh0X2V4 dGVudHMpOiBXaGVuIERpcmVjdFdyaXRlIGlzIGFjdGl2ZSwKbWVhc3VyZSB0ZXN0IHVzaW5n IEdESSBjb2RlIGJlZm9yZSBjYWxsaW5nIHczMl9kd3JpdGVfdGV4dF9leHRlbnRzLgotLS0K IHNyYy93MzJkd3JpdGUuYyB8IDQgKy0tLQogc3JjL3czMmZvbnQuYyAgIHwgNiArKy0tLS0K IDIgZmlsZXMgY2hhbmdlZCwgMyBpbnNlcnRpb25zKCspLCA3IGRlbGV0aW9ucygtKQoKZGlm ZiAtLWdpdCBhL3NyYy93MzJkd3JpdGUuYyBiL3NyYy93MzJkd3JpdGUuYwppbmRleCAxMGFm ODU0NWExMS4uYmMzNzljZDczOTUgMTAwNjQ0Ci0tLSBhL3NyYy93MzJkd3JpdGUuYworKysg Yi9zcmMvdzMyZHdyaXRlLmMKQEAgLTY3OCw2ICs2NzgsNyBAQCB3MzJfZHdyaXRlX2VuY29k ZV9jaGFyIChzdHJ1Y3QgZm9udCAqZm9udCwgaW50IGMpCiAgIHJldHVybiBGT05UX0lOVkFM SURfQ09ERTsKIH0KIAorLyogRG9lcyBub3QgZmlsbCBpbiB0aGUgYXNjZW50IGFuZCBkZXNj ZW50IGZpZWxkcyBvZiBtZXRyaWNzLiAgKi8KIGJvb2wKIHczMl9kd3JpdGVfdGV4dF9leHRl bnRzIChzdHJ1Y3QgZm9udCAqZm9udCwgY29uc3QgdW5zaWduZWQgKmNvZGUsIGludCBuZ2x5 cGhzLAogCQkJIHN0cnVjdCBmb250X21ldHJpY3MgKm1ldHJpY3MpCkBAIC02OTQsOSArNjk1 LDYgQEAgdzMyX2R3cml0ZV90ZXh0X2V4dGVudHMgKHN0cnVjdCBmb250ICpmb250LCBjb25z dCB1bnNpZ25lZCAqY29kZSwgaW50IG5nbHlwaHMsCiAgIGlmIChmb250X3NpemUgPD0gMC4w ZikKICAgICBmb250X3NpemUgPSBGUkFNRV9MSU5FX0hFSUdIVCAoU0VMRUNURURfRlJBTUUg KCkpOwogCi0gIG1ldHJpY3MtPmFzY2VudCA9IGZvbnQtPmFzY2VudDsKLSAgbWV0cmljcy0+ ZGVzY2VudCA9IGZvbnQtPmRlc2NlbnQ7Ci0KICAgcmV0dXJuIHRleHRfZXh0ZW50c19pbnRl cm5hbCAoZHdyaXRlX2ZvbnRfZmFjZSwgZm9udF9zaXplLCBjb2RlLCBuZ2x5cGhzLAogCQkJ CW1ldHJpY3MpOwogfQpkaWZmIC0tZ2l0IGEvc3JjL3czMmZvbnQuYyBiL3NyYy93MzJmb250 LmMKaW5kZXggZjQ0YTdjMTI0YzkuLjdmNTRkNmM2OGYxIDEwMDY0NAotLS0gYS9zcmMvdzMy Zm9udC5jCisrKyBiL3NyYy93MzJmb250LmMKQEAgLTQ0NCwxMCArNDQ0LDYgQEAgdzMyZm9u dF90ZXh0X2V4dGVudHMgKHN0cnVjdCBmb250ICpmb250LCBjb25zdCB1bnNpZ25lZCAqY29k ZSwKIAogICBtZW1zZXQgKG1ldHJpY3MsIDAsIHNpemVvZiAoc3RydWN0IGZvbnRfbWV0cmlj cykpOwogCi0gIGlmICh3MzJfdXNlX2RpcmVjdF93cml0ZSAodzMyX2ZvbnQpCi0gICAgICAm JiB3MzJfZHdyaXRlX3RleHRfZXh0ZW50cyAoZm9udCwgY29kZSwgbmdseXBocywgbWV0cmlj cykpCi0gICAgcmV0dXJuOwotCiAgIGZvciAoaSA9IDAsIGZpcnN0ID0gdHJ1ZTsgaSA8IG5n bHlwaHM7IGkrKykKICAgICB7CiAgICAgICBzdHJ1Y3QgdzMyX21ldHJpY19jYWNoZSAqY2hh cl9tZXRyaWM7CkBAIC01MzAsNiArNTI2LDggQEAgdzMyZm9udF90ZXh0X2V4dGVudHMgKHN0 cnVjdCBmb250ICpmb250LCBjb25zdCB1bnNpZ25lZCAqY29kZSwKICAgLyogSWYgd2UgZ290 IHRocm91Z2ggZXZlcnl0aGluZywgcmV0dXJuLiAgKi8KICAgaWYgKGkgPT0gbmdseXBocykK ICAgICB7CisgICAgICBpZiAodzMyX3VzZV9kaXJlY3Rfd3JpdGUgKHczMl9mb250KSkKKwl3 MzJfZHdyaXRlX3RleHRfZXh0ZW50cyAoZm9udCwgY29kZSwgbmdseXBocywgbWV0cmljcyk7 CiAgICAgICBpZiAoZGMgIT0gTlVMTCkKIAl7CiAJICAvKiBSZXN0b3JlIHN0YXRlIGFuZCBy ZWxlYXNlIERDLiAgKi8KLS0gCjIuMzUuMS53aW5kb3dzLjIKCg== --------------0cpI14QPugXTTpxK0y0cRtmy--

Sans serif collection is an important font collection on Windows, since it supports a lot of scripts. So it would be good for Emacs to support it in a reasonably good fashion.

The problematic font here is "Sans serif collection", which gives very big ascent and descent values for glyphs. Not even Windows own tools, such as charmap or the font selection dialog, render this font correctly. Emacs' code without directwrite directly inspects the glyph outlines to get metrics. I'm looking for a way to do the same with directwrite, or find another solution.
