Different signatures from the same image

While testing my DLL which interfaces MagickWand to the REXX scripting language I came across an oddity with image signatures. I converted wand/drawtest.c to a rexx script and then verified that the rexx script and the C program output the same image by doing a verbose identify (on the command line)...

Thanks.
MagickSetImageMatte isn't in the 6.2.6 code that I've been using - it only has MagickSetImageMatteColor. I really must upgrade.

Setting image/wand opacity

I would like to use MagickWand to read in a JPG image, which does not have an opacity layer, and then set it so that it does have a given opacity (which should implicitly force the image's matte value to MagicTrue) so that I can use it in subsequent operations requiring that it have a matte/opacity ...

That's the compiler I'm using now.
Is there some way you could post or email me the code, .sln file etc. for me to try?

MagickWand and Animation

I've written a simple C program which uses MagickWand to convert 11 successive GIF images into a single animated GIF file. This is the code for the function which does that: #include <windows.h> #include <wand/MagickWand.h> #include "animate.h" char *flist[] = { "animate-00.gif", "animate-01.gif", "...

I installed 6.2.6-1 from the windows binary and tried it again (I was previously using my own compiled version). GetConfigureList now correctly returns 8 items but ListTypeInfo, ListCoderInfo and ListConfigureInfo all crash when used as shown in the second code snippet in my original message. I vagu...

We assume you declared *p as char **p?

Problems with GetConfigureInfo, ListConfigureInfo etc.

I'm using 6.2.6 on Win XP Pro system. The GetConfigureInfo function doesn't seem to be returning the correct info. The configure.xml file contains eight configure entries but the GetConfigureInfo function says that there are 16 and when I list them, it has each of those eight entries duplicated. Thi...

Your problem may be related to the bug I have described in my post "BMP resolution units". If you interpret 28.34 as being pixels per centimetre then multiplying by 2.54cm/in gives 72 pixels per inch. So that number is correct provided that you realize that it is pixels per centimetre rather than pe...

BMP resolution units

There's a bug in the bmp.c coder. It correctly converts the x and y resolution values from pixels per metre to pixels per centimetre but it leaves the units as undefined which means that the resolution and units won't be correctly propagated when converting to other image formats (such as PNG,JPG et...
